How to Maintain Your Air Exchanger in the Summer

Air exchangers are being installed more and more in our homes, which are more and more airtight and tend to lack air. Generally used during the winter to keep the room temperature up while refreshing the air brought in from outside, air exchangers are used differently once the beautiful days arrive. Many owners of these ingenious devices wonder how to use their air exchangers once the summer comes. And with good reason: Air exchangers aren’t used the same way in the summer, because you’re mostly looking to filter the outdoor air while avoiding heating up the room. This is especially an issue for people with an air exchanger and an air conditioning system at home, to avoid wasting energy.

Adjust the settings

Before wondering about the maintenance of your air exchanger, you should adjust it to the temperature outside. Indeed, by continuously bringing in fresh air from outside into your home, these machines could potentially be bringing in more heat and humidity. You should therefore adjust the settings of your air exchanger by referring to the brand’s conditions of use. If possible, you should adjust the settings to switch to “recirculation” mode during the warm season. This effectively limits the entrance of moisture and lets the air circulate throughout the house.

Replace the filters

Some air exchangers come with replaceable filters, while others are permanent. In both cases, it’s important to note the replacement of the filters on your calendar each season, or more often if you live on a street with a lot of car and truck traffic. Replaceable filters should be replaced according to the instructions from the manufacturer, and for those that aren’t, you should also refer to the user manual to learn how to remove the filters. These should be cleaned with a vacuum cleaner before being washed with warm water and mild soap.

Clean the exchanger

Often considered one of the most neglected machines in the house, the air exchanger is one that must be maintained very regularly. For an exchanger to be able to filter and purify the air inside, it seems logical for it to be as clean as possible. You should therefore clean the exchanger core each season, especially before the summer, because the beautiful season comes with allergens, dust, and other pollutants.

Observe

Once all these elements have been taken into account, it’s important to observe the effect of your air exchanger on your interior. For example, the issue of moisture is important, and you should make sure to monitor the humidity level in your home and the impact of your air exchanger on it. The same goes for the air conditioner. If you notice that you tend to reduce the temperature more than usual in the summer, it’s best to see if the warm air isn’t being caused by the use of the air exchanger. In these cases, you might consider completely shutting off the air exchanger in the summer to avoid wasting more energy. As a reference, here are the humidity levels that you should aim to have in a house, depending on the temperature outside:

  • Outdoor temperature between 10°C and 20°C: approximate humidity level of 55%
  • Outdoor temperature between 0°C and 10°C: approximate humidity level of 50%
  • Outdoor temperature between -10°C and 0°C: approximate humidity level of 40%
  • Outdoor temperature between -20°C and -10°C: approximate humidity level of 35%
  • Outdoor temperature between -30°C and -20°C: approximate humidity level of 30%

Keeping your indoor environment fresh and ventilated is essential for a healthy home that will be kept in good condition for longer. Air exchangers are an excellent option for this, especially with increasingly insulated homes. In any event, consulting a professional is always recommended to ensure proper maintenance.
