6 Chronic Respiratory Diseases That Can Be Caused by Contaminated Ducts

The presence of mould and bacteria in indoor spaces has become a major concern in Canada, as it carries serious risks for the health of the occupants of a place. The inhalation of the particles and mould spores retained in the ducts of household appliances causes many respiratory illnesses. Here are 6 respiratory diseases that can be caused by contaminated ducts.

Contaminated ducts and respiratory illnesses

The ducts of your household appliances, such as those of poorly maintained washers and dryers, can quickly get clogged with mould and dust that then spread through the air, especially due to the venting of hot and contaminated air inside a home. Mould related to moisture in the ducts of household appliances proliferates and colonizes the unit and quickly finds itself in the ambient air.

Many of these mould spores produce mycotoxins, which are metabolites or by-products of mould. These particles are recognized as being highly toxic to both humans and animals. Indeed, over time, these toxins will weaken the immune system and lead to sudden allergies as well as trouble breathing.

The most common symptoms of diseases related to the contamination of the ducts of household equipment are the following:

  • Irritation of the eyes, nose, and throat
  • Strong, dry cough
  • Nasal congestion,
  • Wheezing
  • Difficulty breathing
  • Shortness of breath
  • Fatigue
  • Headache
  • Trouble concentrating

When it comes to breathing problems in particular, the mould spores, dust, and germs that contaminate ducts may also increase allergy symptoms such as wheezing, trouble breathing, and shortness of breath. Children, the elderly, people with immunosuppression, and people who recently had surgery are usually the most likely to experience health problems caused by mould spores. If the mould problem isn’t treated at its source, over time, the contaminated ducts can lead to certain serious conditions such as:

  • Rhinitis
  • Bronchitis
  • Asthma
  • Hypersensitivity pneumonitis
  • Allergic alveolitis
  • Allergic bronchopulmonary aspergillosis

Getting rid of the mould in your ducts

If you have one or more symptoms of a respiratory illness, in addition to consulting a doctor as soon as possible, you absolutely must try to determine the cause of your health problems so as not to make the situation worse. The cause of the presence of mould can be found in the ducts of your appliances and may be due in particular to the presence of moisture. Once the presence of mould in your ducts has been noted, it’s recommended to do a big cleaning according to the recommendations of professionals and to replace – if possible – any items that are overly contaminated with infected material or likely to reproduce the same problem. Avoid producing any dust during the cleaning, and clean your filters and ducts using good disinfectant products that are safe for your health.

The recommended cleaning method varies according to the extent of the contamination and the severity of the damage caused to the ducts by the mould. Before starting any cleaning of a contaminated duct, it’s necessary to take a few precautions; in particular, make sure that you can ensure your respiratory protection. To tackle mould problems without risking infecting yourself again, it may be necessary to rely on a company that specializes in cleaning these types of elements, that is familiar with the problems related to humidity and mould, and that has items to protect themselves as well as the appropriate equipment for long-term decontamination.

Our Cleaning Tips for Confined Spaces

The most confined spaces of a house or a building hosting professional spaces are real hiding places for germs. Unfortunately, they are also more or less enclosed spaces that are very hard to access for a truly effective cleaning. Here are our most effective cleaning tips for getting rid of germs and making the confined spaces of your home as clean and healthy as possible:

Clean your vacuum cleaner: Because the vacuum cleaner sucks up dirt but also expels air, it moves the germs and bacteria present all over the house when you use it hoping to clean your interior. To prevent the germs from spreading everywhere, or a little less, you should regularly throw away the dust bag and clean the filter as often as possible. Vacuum cleaners and their accessories are great nests for bacteria. However, you should be aware that some modern vacuum cleaners are equipped with a system that only expels clean air.

Give your interior a big spring cleaning: Once or twice a year, and especially when the seasons change, it’s a good idea to give your interior a big spring cleaning to get rid of the germs and bacteria that may be hidden in the confined spaces. A big spring cleaning lets you:

  • Purify the air in your house
  • Make your interior shine
  • Clean all the surfaces
  • Eliminate any trace of dirt
  • Regain total well-being
  • Put your things in order

Choose your disinfectants well: In confined spaces, there’s a tendency to clean and disinfect the space too much using extremely aggressive chemical detergents to reassure yourself that you’ve eliminated the germs. However, you should know that these products have an impact on the environment, the air you breathe, and therefore the health of the occupants. These products can be much more harmful than some germs! So consider using the most neutral detergents possible. Generally speaking, the longer a product’s list of ingredients, the more harmful it is! It’s best to use scent-free cleaning products with a plant-based cleansing base.

Regularly air out confined spaces: When we allow the air to renew itself by opening the windows for a few hours or even a few minutes a day, the results are there: the germs and bacteria fly away. If a space is confined, you’ll have to find some way to create ventilation, such as by installing a hatch that lets the air pass through it and renew itself regularly.

Opt for high-pressure cleaning: Depending on the type of confined space that you want to clean without the risk of damaging it, you can opt for high-pressure cleaning using a special machine. Whether it’s for industrial cleaning or cleaning a rather confined space, the high pressure lets you powerfully clean the hardest areas to clean by hand, as well as furniture. High-pressure cleaning lets you clean even the dirtiest areas quickly and efficiently.

If the confined space that you need to clean to sanitize your interior is too full of embedded dirt and grime, don’t hesitate to call on cleaning professionals who have the experience to get rid of everything that’s unbearable for you to clean. A company that specializes in cleaning has the high-pressure equipment you need and will do a thorough cleaning with products that respect your health as well as the environment.

Dryer Vent Hose: How to Choose Between Aluminum and Plastic

Did you know that the poor maintenance of dryers and dryer vent hoses carries a high risk of fire in your home? Some types of dryer vent hoses are more likely to cause fires. You should therefore make the right choice between aluminum and plastic.

Our precautions to take

  • It’s best to have your dryer installed and maintained by a professional capable of taking precautions against fires.
  • It’s best to choose a material such as rigid metal for your dryer vent hose, which is much less flammable than plastic or aluminum.
  • If you install your dryer yourself, follow the instructions from the manufacturer before installing the dryer vent hose. Run your hose along the most direct possible route to the outside to prevent the accumulation of lint in the curves and bends of the hose.
  • Using rigid or flexible metal vent hoses is the best alternative. Plastic hoses are more likely to warp, sag, and get crushed, which encourages the accumulation of lint. Plastic hoses are also much more likely to melt and catch on fire.
  • For better removal of the hot air, choose the shortest and straightest possible exhaust air hose.
  • Dryers installed in a closet or a confined space in a small apartment, for example, must have an air intake sufficient for their proper functioning.
  • Avoid the formation of condensation and the accumulation of lint as much as possible from the very beginning of your machine’s operation. Don’t wait for it to get clogged.
  • Insulate your hose if it runs through an unheated area such as a basement.

The ideal dryer vent hose:

The ideal dryer vent hose is made of metal, preferably smooth and rigid, and 4 inches in diameter. It is also as short and straight as possible, and its corner connectors are assembled without screws or fasteners that extend inside the device. Finally, it is connected to an exterior element equipped with a valve that opens automatically when the device is working and protected by an insulating sheath if it runs through an unheated space.

Daily precautions:

  • Make sure that your dryer’s connection hose and exhaust duct are always in good condition, not damaged, and well placed.
  • If you have a dryer with a white plastic hose, try to replace it to reduce the risk of fire.
  • Consider inspecting and cleaning your dryer filter after each load of laundry by removing the clumps of material.
  • Clean the inside of your dryer regularly as indicated by the manufacturer.
  • Stop the dryer if you are going out so as never to leave it running unattended.
  • Make sure to never put a flammable object near the dryer while in use to prevent fires.
  • Make sure to have a fire and smoke alarm installed in your home on each floor, especially near the bedrooms.
  • Avoid drying too much laundry at the same time and avoid drying laundry that may have come into contact with flammable chemicals.

To choose a hose for your dryer, follow the advice of professionals and consider having your device maintained by people who specialize in duct cleaning to prevent any risk of fire, whatever material the hose is made of. Relying on a specialized company means avoiding the obligation to replace your dangerous and defective equipment. Indeed, professionals can repair your dryer and give you great advice for better maintenance.

Dryer Vent Exhaust Inside the House: Why Is It Not Recommended?

As you can imagine, the air in a dryer contains a large amount of dust and fine particles that you don’t want to see build up in the indoor air that you breathe. In addition, for each load of laundry, at least a gallon of water is removed from the dryer vent exhaust inside, which makes the humidity level in a house increase and causes condensation as well as the appearance of mould!

Why shouldn’t you release the air from the dryer inside?

Because a regular dryer filter only traps the biggest fibres, the dust and the finest particles present in the laundry that you’re drying will stay in the exhaust air released inside your house. If you want to release the exhaust air from the dryer in your laundry room to save energy, then you should add a second filter to trap the fine particles and take rigorous maintenance precautions.


According to the Canada Mortgage and Housing Corporation (CMHC), the humidity level in your home should not exceed 50% in the winter and should be further reduced to around 30% when the temperature falls below -10 degrees Celsius. An indoor dryer vent exhaust can raise the humidity level and create condensation and mould issues, which are dangerous for your health. So consider closely monitoring the humidity level in your home.

The negative effects of humidity

An excessive humidity level in a home can cause the appearance of mould on the walls and tile joints, the formation of fungi and saltpetre, the rotting of the woodwork, or very bad smells. Moisture can therefore damage the furniture and all the elements of a home very quickly if it’s not controlled.

However, the worst part is the negative effects that moisture can cause to the health of the occupants of a place. It promotes the appearance of various allergies that didn’t exist before, such as allergies to mould and dust mites. If the presence of fungi and dust mites becomes too great, these allergies can then turn into respiratory diseases such as chronic bronchitis and asthma, as well as conditions such as rhinitis and conjunctivitis. In particular, it’s the youngest and the oldest who are most at risk of contracting these diseases, which usually begin with sneezing and a heavy cough.


Did you know that many dryer fires are reported each year due to dryer hoses clogged with fibres from clothing? Neglecting the cleaning of your dryer ducts can therefore have serious consequences.


To avoid the risks:

  • Empty and clean the lint filter after each use
  • Rinse and wash the filter with soapy water every 6 months
  • Choose metal hoses instead of plastic
  • Don’t run your dryer unattended
  • Don’t run your dryer without the lint filter
  • Have your pipework inspected and maintained by professionals
  • Avoid overfilling your dryer
  • Take care to ventilate the area near your dryer
  • Moderate the use of paper, such as fabric softener sheets

In all cases, to prevent moisture problems, polluted air, and the risk of fire, you should clean up your dryer filter after each use and have a more substantial cleaning carried out regularly by professionals. You can also replace the filter fairly often to prevent the thickness of the compact dust from interfering with the normal operation of your dryer.

What Are the Ventilation Options for a Bathroom Without Windows?

Choosing the right ventilation system for a bathroom without windows is essential, because ventilation lets you reduce the humidity and breathe healthy, unpolluted air. If the ventilation isn’t ensured by a window, it can come from a CMV or an air extractor. In a bathroom, ventilation is also important for the comfort that the renewal of the air provides to this very humid room.

The importance of ventilation in a bathroom

The ultimate humid room, the bathroom, much like the kitchen, is a separate room in a house that needs to be properly ventilated, especially because it receives direct contact with water and moisture. Its proper ventilation is necessary to ensure the well-being of the occupants of the premises, whose health can be affected by an excessive humidity level in the air, which can cause breathing problems or skin or eye infections. It also helps prevent condensation and therefore the deterioration of the paint, coatings, furniture, or electrical systems.

The solutions for proper bathroom ventilation

  • Natural ventilation: Even if your bathroom doesn’t have a window to the outside, it can have direct contact with the outdoor air via a grid or a ventilation duct. You can also opt for a window aerator, which is a possible solution only if your bathroom has a condemned window. In effect, the window aerator is installed on either side of a window thanks to a cut-out in the panes. It works manually or by being connected to the home’s power grid. However, bathrooms are too humid for this type of light ventilation system to be enough to eliminate the moisture, and you should therefore invest in an additional system.
  • Centralized mechanical ventilation (CMV): A regular or double-flow CMV is installed in most bathrooms in new homes in Québec. Affordable on the price level, a CMV continuously removes the air and moisture present in the room and works by being connected to an air extractor duct, generally located in the attic of a house. A simple CMV has the disadvantage of sometimes making a room colder, while a double-flow CMV, which is more expensive, will preserve the heat in the room for the comfort of its occupants.
  • An air extractor: An alternative to a CMV, an air extractor, also known as occasional mechanical ventilation (OMV), is a simple duct connected to a ventilation duct that starts working with a switch that allows you to turn the system on and off. Some models also let you automate the ventilation at fixed and scheduled times or detect moisture and movement. Easy to have installed by professionals, it’s an economical ventilation system that is often implemented during a bathroom renovation. In particular, you can opt for a hot air extractor that will store the heat emitted in the bathroom to distribute it throughout all the rooms in the house and thereby save energy.

If you have the ability to choose, especially in terms of the budget for the ventilation of your bathroom without a window, we recommend opting for a hot air extractor, especially a model with a switch that is independent from the one that is connected to the lighting. An independent fan lets you leave the fan on long enough to eliminate all the moisture while allowing you to leave the room or turn off the light.

Air Duct Cleaning: What Are the Risks of Not Doing It?

Ventilation ducts are indoor air ducts that are used to circulate air and extract and recover the air from the heating or air conditioning systems in residential buildings, offices, industries, or any other type of building. If ventilation ducts aren’t cleaned, they circulate contaminated air that can transmit pollution that is dangerous for your health.

The risks associated with not maintaining an air duct

Essential to the exchange of air between the inside and the outside and to the use of the heating and air conditioning systems, ventilation ducts are heavily used and cleaning them contributes greatly to managing the quality of the ambient air and therefore to the health and well-being of the people present in a place. If the ventilation ducts in your building aren’t regularly cleaned, there are several types of risks:

  • Risks to the health of the occupants of the premises: Poorly cleaned air ducts will be a place where dust proliferates, which will cause the formation of mould, various bacteria, and allergens that will then be transported in the ambient air. In this case, the air breathed by the occupants of the place can cause irritations in the respiratory tract, itching, asthma, and incessant allergies. The major risk is developing serious lung problems due to the impure air breathed on a daily basis.
  • Risks of fire: The accumulation of dust, grease, and smoke in the ventilation ducts, and especially in the hood vents in the kitchen, represents a high fire risk as soon as you turn them on. In addition, in terms of comfort, the risk of poorly maintained kitchen hood vents is having unpleasant odours appear that won’t go away because they’re caused by the incrustation of dirt on the walls of the device.
  • Risks of reduced quality and durability in your devices: The risk of the premature deterioration of your devices – whether it’s your heating systems, your air conditioner, or your kitchen hood vent – is great if you don’t take the cleaning of the ventilation ducts seriously. The motor of your ventilation ducts can also overheat if they aren’t regularly cleaned, because the amount of air will become too large compared to the volume of the ducts lined with impurities.
  • Risks of additional costs: The regular maintenance of a ventilation duct helps ensure the smooth operation of your devices but also reduces the overall cost of the repairs that may be required if its maintenance is not ensured. A ventilation duct maintained by a professional in a high-quality way on time will prevent you from having to buy expensive maintenance products regularly or having to completely replace your ducts! Without cleaning the ventilation systems, your heating devices will also function worse, which will force you to increase the thermostat and therefore make your heating bill go up more and more.

For maximum efficiency and because air duct cleaning requires safe and appropriate professional equipment, you should have your air ducts cleaned by experienced cleaning professionals. Experts will be able to offer you lasting maintenance, sanitation, decontamination, and cleaning services for your ventilation ducts because they’re carried out with the proper required equipment. For an optimal result, you can have your ventilation ducts cleaned once or twice a year, before and/or right at the end of winter.

Hot Air Extractors: How Do They Work?

In both new and older homes, ventilation problems can arrive quickly and cause health problems such as eye irritation, headaches, and breathing problems in the inhabitants of the premises. These symptoms caused by the pollutants contained in the ambient air can be avoided by installing a hot air extractor.

How does an air extractor work?

Air extractors are sophisticated technological devices that replace the impure air contained in your walls that pollutes your atmosphere with fresh, unpolluted air. Indeed, the ambient air may contain fumes from the chemicals that we use to clean our interiors, for example, as well as harmful gases, volatile organic compounds, bacteria, mould, moisture, tobacco smoke, or bad smells. The modern insulation of new homes is likely to bring us even more atmospheric pollution due to its high capacity to prevent the movement of the air. Moisture and pollutants therefore remain trapped in the interiors of buildings. The standard for air renewal is considered to be a renewal every two to three hours in a home or professional space occupied all day or night. In that sense, it seems difficult to achieve this standard in the middle of winter in Québec, where the temperatures don’t allow for proper ventilation without consuming energy unnecessarily.

The features of an air extractor

  • Replacing the indoor air with outdoor air in well-insulated homes.
  • Managing excess humidity levels, which are dangerous for our health, especially in the winter.
  • Ridding the ambient air of various pollutants, such as chemicals, gases (radon), bacteria, and mould.
  • Ensuring that the air you breathe is of good quality.

The additional features of a hot air extractor

An air extractor extracts and introduces air simultaneously in an interior environment, which helps purify the air by ridding it of atmospheric pollutants. In addition to that, a hot air extractor recovers the heat from the air extracted from the home to the outside and transmits it to the air introduced into the home. The hot air extractor is generally installed in bathrooms and introduces the outdoor air into the rooms of a house, such as the living room, the bedrooms, and the regularly closed rooms. It’s a very useful device in the winter and a particularly good option in Québec, a region with a cold climate during the season. If not, there are two other options for devices: the air extractor without heat recovery and the air extractor with energy recovery. An air extractor with heat recovery also has the advantage – compared to a simple air purifier – of saving you energy and therefore money on your bills.

What humidity level should be maintained in a home?

The humidity level refers to the amount of water present in suspension in the air. When it’s between 10 and 20 degrees Celsius outside, this can be 55%, while it should be 35% when it’s a temperature between -10 and -20 degrees Celsius.

Note: The Canada Mortgage and Housing Corporation (CMHC) alerts Canadians about the humidity level inside their homes, especially during the winter, when it may exceed 50% due to poor ventilation, which promotes the development of harmful mould.

You can have a hot air extractor installed by professionals or have a device already present in your new home cleaned to make it work before the arrival of winter to prevent any risk to your health and that of your family.

What are the Best Ventilation Duct Cleaning Equipments?

A ventilation duct is a relatively confined space where dust naturally gets lodged that tends to form the perfect environment for the rapid proliferation of bacteria, mould, and dust mites. Because a ventilation duct distributes air in an indoor environment, it will therefore distribute – little by little – everything found inside and which is unclean and cause health problems in the living beings who are breathing the ambient air on a daily basis. Fortunately, there is cleaning equipment out there for ventilation ducts.

Ventilation duct cleaning equipment

  • Pulsion and friction nozzles

A nozzle is a piece of cleaning equipment for ventilation ducts that allows a pulsion and friction system to dislodge any fine particles, grease, and dust from the ventilation ducts. Inserted into each duct one by one, it follows the interior and the walls to dislodge and blow any dirt present to the exit, where it will then be sucked up by an ultra-powerful vacuum cleaner. The nozzle is equipped with a whip often made of rubber as well as air holes that help blow away the dirt on the surface in addition to scrubbing any more embedded dirt thanks to the high-speed rotating action of the whip.

  • HEPA (High Efficiency Particulate Air) vacuum filters

Once the dust has been dislodged from the walls of the ducts through pulsion and friction, it’s time to suck it out of the ventilation ducts with a powerful vacuum cleaner. The equipment for cleaning and sucking up the dust in ventilation ducts doesn’t work according to the same principle as the traditional equipment that dislodges the visible contaminants found inside the system. Professional vacuuming equipment for ventilation ducts consists of specific elements: vacuum cleaners equipped with a HEPA filter that can retain 99.97% of particles over 0.3 microns. A HEPA filter is connected to a vacuum cleaner and to the ventilation duct system to create negative pressure that won’t let any pollutant from the air pass.

These two cleaning methods using pulsion, friction, and suction generally take several hours to obtain a flawless result and keep it over the long term. If you rely on a company that specializes and – above all – has experience in cleaning ventilation ducts, the experts will take the time to check their work, in particular by using a camera inserted into the duct.

  • Biocide to sterilize the ducts

For a thorough cleaning of your ventilation ducts, professional cleaners will also take the precaution of properly cleaning the filter of the ventilation system using specific products so as not to damage your equipment. At the end of the cleaning, it’s also good for the durability of your equipment to use a natural biocide to sterilize the ducts with a biodegradable product that is safe for your health. To do this, rely on a company that has high-quality, eco-friendly products that can sterilize your air ducts to see more lasting effects from your professional cleaning.

Cleaning your ventilation ducts isn’t just a matter of cleanliness; it’s also an important health issue, because they’re the ducts of the ambient air in your interior and the air you breathe, and can therefore transport dirt and microbes of all sorts. Whether you’re the owner of a residential or professional building, make sure to take the necessary precautions for the health of all the occupants of the premises.

Sludge Removal from a Heater: What Are the Causes of this Accumulation?

Sludge removal involves cleaning the entire central heating system to eliminate any sludge that may have accumulated in the circuit of a building naturally over time. Sludge accumulation is a natural phenomenon that occurs when the oxygen contained in the heating system reacts with the metals and triggers a redox reaction.

What are the causes of sludge accumulation?

Because the central heating system uses water as a heat transfer liquid for the energy and water is a corrosive element, the metallic parts made of copper, steel, or aluminum are subject to corrosion. Sludge is formed and affects the pipes, radiators, and even boilers at a speed that depends in particular on the quality of the water in your water system. Sludge removal is therefore recommended when a sign of deterioration appears in your circuit – every 5 to 10 years for regular heaters, depending on the quality of the water in your circuit, and every 5 years maximum for heated floors. When replacing and installing a new boiler or new heaters in your home, sludge removal must also be systematically performed.

Recognizing sludge accumulation

  • Coloured purge water: When you go to purge or even replace your radiators, consider checking that the purge water isn’t red, orange-ish, or black in colour to recognize sludge accumulation and prevent the deterioration of your heating system, which can be very rapid in this case.
  • Increased energy consumption: Because sludge accumulation doesn’t allow your boiler to work at its maximum capacities, it will consume much more than usual and therefore increase your energy consumption and your bill!
  • Blocked heating system: If you notice a decrease in the heat level and significant difficulty reaching the same temperature as before, your boiler may be blocked by sludge. Sometimes, cold zones may also appear because of poor hot water circulation due to a sludge accumulation that is blocking an area.
  • A very noisy heating system: If your heaters and/or boiler are noisier than usual, the accumulation of sludge, like that of limescale, may be the source of this problem, which can only be solved after cleaning. Be careful: uneven deposits that cause targeted and considerable noises in certain places in the heating system can also cause cracks.

Sludge removal techniques

Often, people who want to remove the sludge from their heating system use water combined with a powerful cleaning solution to rinse the system, but this generally only eliminates the sludge and limescale in suspension. For deposits that are embedded in the system, the pipes, or the heated floor, the best cleaning solution involves using a mechanical machine with a forced air system. These devices use hydrodynamic sludge removal to create jets that will dislodge then propel the particles, which can then be removed by rinsing the entire circuit with clear water.

Rely on cleaning professionals who know how to remove sludge from specific systems such as heating systems for the fast and effective maintenance of your heating system.

Sludge removal is a maintenance and protection solution for your heating system and an effective way to reduce your bill by saving energy and reducing your impact on the environment. Finally, it’s a solution to have a heating system that performs at all times and to avoid finding yourself with breakdowns during the winter!

Cleaning a Wall-Mounted Air Conditioner in 3 Steps

To optimize the performance of your wall-mounted air conditioner, it’s important to clean it at least once a year, and before its period of heavy use – that is, the summer season. If you have pets, you’ll undoubtedly need to maintain it regularly to remove the hair that often gets lodged in the filter of the device. Here are the 5 steps for cleaning a wall-mounted air conditioner before the warm season:

Before starting your wall-mounted air conditioner cleaning job, always take the precaution of checking that it is in the off position and disconnect it from the power supply.

Remove the casing from your wall-mounted air conditioner

To start cleaning your device, you must first remove its casing to be able to access the evaporator coil, which is the most important part to clean. To do this, equip yourself with a cleaning product specially designed for refrigerator or wall-mounted air conditioner coils, which you can find in large specialty stores. This product will probably be a chemical that you will have to handle with care and especially with gloves. It will also need to be a powerful antibacterial product that will prevent the formation of mould or bacteria in the long term. Finish this step with the complete rinsing of the coil with clear water to remove any excess dirt. The mould and bacteria that accumulate within this type of device are very hazardous to human health and are responsible for poor indoor air quality, which can cause asthma, various respiratory illnesses, lung infections, and even lung cancers.

Clean the interior unit

Using a sufficiently powerful vacuum cleaner, begin by vacuuming the dirt inside the unit, then scrub the surface with a damp sponge soaked in soapy water and wrung out well, then dry everything with a soft, clean cloth. The filter must always be perfectly dry before being replaced in the interior unit of the wall-mounted air conditioner. This cleaning of the interior unit should ideally be carried out every two weeks for the duration of its daily operation to reduce the accumulation of dust on its walls and filter. If you don’t clean the interior unit often enough during the warm season, you risk losing significant air flow, which will reduce the efficiency of the machine and increase the energy consumption and noise of the device. If you don’t think you’ll remember to clean the filter of your wall-mounted air conditioner regularly enough, you can opt for a device equipped with an indicator that will notify you of the right time to clean it.

Clean the condenser

While cleaning the inside of a wall-mounted air conditioner might seem like the most essential step, it’s also necessary to regularly clean the condenser, which is located in the exterior part of the device, in order to keep your device in good working order. To do this, move a cloth dampened in soapy water and thoroughly wrung out along the entire exterior surface of the unit, then wipe the whole thing with a soft, dry cloth that won’t risk creating scratches. Then, make sure that the exterior coil is also clean or wipe it with a damp cloth to get rid of all the accumulated dust and dirt.

If your wall-mounted air conditioner is very dirty but still in working order and the task seems difficult, you can always call on a professional cleaning company, which will take care of making it like new again while being careful not to damage it.
