Ensure ventilation and eliminate excess moisture, preventing the growth of mould that can cause health problems. Air exchangers also prevent condensation from forming on walls and windows. Many factors can increase the humidity in your home (showers, condensation from breath, plants, cooking, etc.).
Can you install an air exchanger yourself?
A: The short answer is yes. A heat recovery ventilator can work in a home with no ducts.
Is an air exchanger good?
Exchangers use one fan and vent system to blow indoor air outside, while another sucks fresh air in. Air exchangers are a great solution to indoor air quality problems–especially when the cold forces you to stay indoors.
Should I use my air exchanger in the summer?
The answer depends on your home’s air conditioning system, your ERV wall control, the outdoor temperature and, most importantly, the outdoor relative humidity. As a rule of thumb, if you are more comfortable outside than inside your house, you should run your air exchanger in the summer.
Does an air exchanger remove humidity?
How Do Air Exchangers Work? During the summer and in warm weather, the air exchanger will remove the outdoor heat and humidity before the filtered air enters the home. Typically, homes in colder climates have a heat recovery ventilator that is designed to retain heat without reducing the humidity.
Do I need a dehumidifier if I have an air exchanger?
Do You Need a Dehumidifier If You Have An HRV? The answer is Yes, generally speaking. Just like we already stated, an HRV may not remove as much humidity as a dehumidifier. This is because a lot of heat and moisture exchanges take place depending on the season.
How much are HRVs?
Cost of an HRV or ERV System. A whole-home HRV or ERV system can range anywhere from $1000 to $4,500+ with installation.
Are air exchangers mandatory in Ontario?

What size air exchanger do I need?
ERVs/HRVs are typically sized to ventilate the whole house at a minimum of . 35 air changes per hour. To calculate minimum CFM requirements, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by .
Can you put air exchanger in attic?
Advantages of installing an air exchanger in the attic
Air exchangers can be noisy, and they usually take up a lot of room. By placing it in the attic, the inhabitants aren’t bothered by the noise of the fan and can take full advantage of the benefits of such an installation.
Does an air exchanger cool the house?

How long does it take to exchange air in house?

Should you turn your air exchanger off in the winter?
Should I Run The Air Exchanger During Winter? Every home is different depending on how much condensation builds up during the winter, Simple answer is yes. During the winter, your home will experience high amount of condensation due to the insulation and moisture barriers (Thermo poly).
How long does an air exchanger last?
Like most other HVAC systems, an air exchanger can last as long as 15 to 25 years, depending on how well or badly it is used.
When should you turn off your air exchanger?
Pulling humid summer air into your home forces your air conditioner to work harder to compensate for it. As a result, your air conditioner will run longer and drive up your bills. As long as you’re using your air conditioner, consider switching off your air exchanger.
