An air exchanger is one of the devices in the house that we end up forgetting: it works, you have found a way to regulate its control and you don’t think about it anymore. However, there is one thing all air exchangers have in common: a filter!
It is not uncommon to hear from air exchanger owners who have never touched the unit since it was installed… a few years ago! Whether in the laundry room, a closet or in an attic, its cleanliness is essential to allow it to function well over a long period of time. It is therefore recommended to clean it four times a year, not counting the annual maintenance of the heat or energy recovery core.
The consequences of a lack of maintenance
The filter is used to prevent the air exchanger from becoming clogged with dust and various debris that was suspended in the outside air and sucked into the unit. The filter can become clogged enough that air cannot pass through! A situation like this can cause certain problems: as the filter on the exhaust side of the air exchanger becomes clogged much less quickly, the air continues to come out even if it cannot enter. The house is then in depression and the air infiltrates through the cracks, crevices, and openings more numerous than one thinks.
When the exhaust filter is also clogged, the operation of the air exchanger is unnecessary, as it no longer does its job. You, therefore, find yourself in an envelope sealed with the outside and you breathe the stale and polluted air of your house because it is not renewed.
Ultimately, the lack of filter maintenance also makes the fans dirty and requires cleaning. The operation which must be carried out by a qualified technician.
When to call a professional?
Even if you do a minimum of the maintenance yourself, you should do a thorough cleaning of your air exchanger and ducts at least every three to five years. If you are doing renovations or have smokers or long-haired pets in the house, maintenance will need to be done more frequently. Observe the state of cleanliness inside your air exchanger. If it is dirty, it is a good indicator that professional maintenance is needed.
What type of maintenance do professionals do?
When servicing your air exchanger, the technician checks the appliance controls. This means that it checks the electrical connections, the condition of the propeller, the sound level and the vibration level. It also checks the operation of the components and adjusts them as needed. Clean the filter and core and lubricate the motors. The technician then cleans the air filters, takes a look at the exhaust ducts and the air exchanger, and cleans the latter as needed.
While cleaning the ducts, professionals use an industrial vacuum with a rotating brush and a HEPA filter. Its cleaning techniques provide clean ducts, free of dust, bacteria and mold, adequate ventilation and clean air. The quality of your air will improve considerably. At the same time, they check the condition of the ducts and change or clean the air filters.
