Why is an air exchanger mandatory?

Quebec is known for its harsh winters and hot, humid summers. For this reason, it is essential to maintain good indoor air quality in our homes and buildings. That is where air exchangers come in. Air exchangers are ventilation systems that renew indoor air while recovering some of the heat or freshness from the outgoing air. They have been mandatory in new construction in Quebec since 2012. In this blog, we will explore why air exchangers are mandatory. We will also explain how they can improve your home’s indoor air quality.


What Is the Novoclimat Program?


Established by the Quebec government, the Novoclimat program is a major initiative that enables homeowners to build energy-efficient buildings. Homes built to Novoclimat standards are more efficient in terms of energy consumption, which translates into savings on electricity and heating bills. What’s more, homeowners can receive financial assistance for the construction of their energy-efficient homes. The amount of assistance depends on a number of factors, including the size of the house, the type of construction and the level of energy efficiency. They can also benefit from advice and assistance in the design and construction of their home. Program experts can help homeowners choose the most efficient materials and systems. Homes built to Novoclimat standards are certified by an independent organization to guarantee their energy efficiency. This certification is a guarantee of quality for homeowners and potential buyers. Finally, the program helps to combat climate change and preserve the environment for future generations.


Regulations on Air Exchangers


Since the summer of 2012, a new Building Code regulation influenced by the Novoclimat standard has been in place in Quebec, with the main objective of improving the energy efficiency of buildings in the region by a significant 25% margin. This means that air exchangers must be designed to recover at least 54% of the heat from the outgoing air to heat the incoming air when the outside temperature is -25°C. The installation of an air exchanger is therefore mandatory in all new constructions or renovations of more than 50% of the residence subject to the Building Code. This includes single-family homes, apartment buildings, businesses, and public buildings.


Why Is an Air Exchanger Mandatory?


First of all, an air exchanger helps maintain good indoor air quality by evacuating stale air and introducing fresh air. This reduces the concentration of pollutants and humidity, which can be the cause of various health problems such as asthma and allergies. In addition, an air exchanger reduces heating and cooling costs by recovering heat from the outgoing air and transferring it to the incoming air. It also reduces excessive humidity in winter and summer, which can damage your home’s structure and encourage mould growth. In short, an air exchanger is an essential element in maintaining a healthy, comfortable atmosphere in your home.


Keeping Your Air Exchanger in Good Working Order


To keep your air exchanger running smoothly, it is essential to follow a few best practices. First of all, it is important to clean your filters regularly, as they can accumulate dust and particles that can block airflow. Next, it is advisable to have it inspected once a year to make sure it is working properly. Finally, it is important to have your air exchanger ducts professionally cleaned. Dirty ducts can affect the quality of the air you breathe. Allergens, mould and bacteria can accumulate in the ducts and cause health problems. Clogged ducts can also reduce the efficiency of your air exchanger, increasing your heating and cooling costs. Professional cleaning will remove contaminants and ensure that your air exchanger is operating at full capacity, allowing you to breathe healthier air and reduce your energy bills.


In conclusion, air exchangers play a crucial role in maintaining air quality inside your home and simultaneously reducing humidity levels, while saving energy. Not only are they mandatory in Quebec, but they are also a sound investment for your health, comfort, and wallet.
