Air exchangers work by circulating stale indoor air out of your home and circulating in fresh air from outside. Exchangers use one fan and vent system to blow indoor air outside, while another sucks fresh air in. … Here are the top four reasons why you should consider having an air exchanger installed today.
Should you run air exchanger all the time?
Your air exchanger is most effective when run continuously. As long as it’s on, your exchanger continuously filters out polluted air and brings in the clean stuff. … Keep your exchanger operating at low settings constantly, and you won’t have to worry about stale air buildup.
How does an air exchanger control 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 you use an air exchanger 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. … You’ll want to set your Air exchanger to the proper humidity level for the winter.Should you run your air exchanger in the summer?

What setting should my air exchanger be on in the winter?
Set the control to the highest setting in warmer weather; lower the setting as the weather gets colder. In winter, set the dehumidistat just low enough to prevent condensation on windows.
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 do you know if your air exchanger is working?
If your air exchanger is working properly, the air exchange must be balanced, meaning that the stale air being drawn out of the living space is being replaced by an equal amount of fresh air. … Turn on the air exchanger and then go outside and find the exhaust air outlet, which is the one that has air blowing out of it.Are Home air exchangers worth it?
For the reason air exchangers save heat, they help saving money as well. As they keep the temperature inside the house regulated, the frequent need of turning on or off the heating or cooling system is eliminated that results into reduced electricity bills.
Do air exchangers have filters?Air exchangers, ERVs and HRVs contain air filters to trap larger contaminants, but some of the dust slips through and settles inside the core, which directs airflow in very specific patterns to facilitate proper ventilation, heat exchange and/or humidity control.
Article first time published onWhat should an air exchanger be set at?
As a general rule of thumb, you should set your system’s dehumidistat to 25 percent to 50 percent depending on the temperature to keep condensation at bay. For instance, 50 percent is the maximum relative humidity you should have if the outdoor temperature is between -11 degrees Celsius to 18 degrees Celsius.
How long should 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.
What is the difference between an air exchanger and an air purifier?
Air exchangers and purifiers remove environmental contaminants from the home. An exchanger exhausts stale air from inside and replaces it with fresh air from outside. Conversely, a purifier detoxes the existing air, making it supplementary to a ventilation system—not substitutional.
When should you have your air exchanger on?
Air exchangers should be run at all time, summer and winter. Depending on the size of your home, energy-efficient air exchangers can cycle through all the air in your home in just a few hours.
Should HRV be turned off in summer?
In a nutshell, you should shut off the HRV humidistatic control as soon as the furnace is not being used on the heat setting. … The damp-feeling air and moisture on the windows in the summer months is proof that running the HRV unit at this time of year is detrimental.
Does a ERV dehumidify?
Although, it should be made clear that ERV systems are not a reliable source to remove moisture; an ERV system is not a dehumidifier and actually guarantees that a dehumidification system will be necessary.
What is a ventilating dehumidifier?
Ventilating Dehumidifier Use as a stand alone dehumidifier, or duct it to your HVAC system, to keep your home’s air dry in the summer. The 70V can be used as a dedicated ventilator to bring fresh air into your home on a schedule determined by you and your dealer.
What is the air exchanger open or closed?
Leaving the vent open allows more fresh air in, but also draws more heat and makes your air conditioner work harder. Leaving the vent closed won’t bring as much heat in, but you would be relying more on filtered air.
Does air exchanger help condensation Windows?
A: Air exchangers are supposed to prevent condensation and mold by bringing in enough fresh air without losing heat through the exhaust air in the winter or adding it in the summer via the incoming air.
Do air exchangers need to be cleaned?
How to keep your air exchanger running smoothly. Some of the components on your air exchanger, such as the recovery core, ventilator, drain pan, and exhaust duct, need to be cleaned at least once a year.
Why does my air exchanger keep shutting off?
A clogged filter limits the amount of cool air that passes over the heat exchanger, causing it to overheat and shut off. At the same time, your blower turns on to help cool it down. … So, if your air filter looks like the one to the right, replace it immediately and see if that fixes the problem. 2.
Do air exchangers make noise?
Clunking and banging noises tend to occur when scale accumulates on the heat exchanger. According to 24/7 Home Rescue, “This blocks the flow of water and causes some water to boil, steam and expand,” as in a kettle. Boilers also whistle, which could be an effect of either kettling or trapped air in the system.
How do you clean the core of an air exchanger?
- Remove the polypropylene heat recovery core from the unit.
- Let is soak in a mixture of either cold or luke warm water with a mild soap (dishwashing liquid).
- Rinse the heat recovery core thoroughly and shake to remove excess water.
How do you dry an air exchanger core?
Remove the heat recovery core. Let it soak in a cold or lukewarm solution of water and mild soap (dishwashing liquid). Rinse thoroughly. Shake the core to remove excess water, and then let it dry.
What is an air to air exchanger?
An air-to-air heat exchanger brings two air streams of different temperatures into thermal contact, transferring heat from the exhausting inside air to incoming outside air during the heating season.
Can you use an air purifier and a fan at the same time?
The general rule is “No.” Air purifiers aren’t fans alone. That is, while they do move and circulate air, most can’t do so with the high speed & larger airflow of a basic electric fan.
Is HRV an air purifier?
The new THH 1.0 True HEPA Heat Recovery Ventilation (HRV) system is setting the standard in the industry as the very first HRV system incorporating true HEPA filtration right into the unit for an optimal indoor air environment.
