With windows and doors tightly closed to keep the warm air inside, you might notice the air in your home is stale. Regularly replacing furnace filters can help, but sometimes you need the help of an additional home system, like an air exchanger, to keep your indoor air fresh and healthy.
There are two main types of air exchangers, an HRV (heat recovery ventilator) and an ERV (energy recovery ventilator). HRVs and ERVs are ventilation systems that circulate air throughout your home using your existing forced-air furnace. These units draw stale air out of your home and replace it with an equal volume of fresh outside air. Filters catch allergens before they enter the home and they both incorporate a heat recovery component. The heat from the warm air leaving your home is transferred to the cool incoming air. This increases efficiency and helps to decrease monthly bills.
The difference between the two systems is that an ERV not only conditions the incoming air but also helps regulate the moisture level. Heat and moisture are pulled from the exiting air and transferred to the dry incoming air, helping to keep the humidity level more constant in the wintertime. Because of this added benefit, we usually recommend ERV systems for homes in our area, since the humidity level can drastically drop in the winter and greatly increase in the summer.
Benefits of an ERV:
- Provide an energy-efficient means to exhaust indoor pollutants to improve indoor air quality.
- Maintain a continuous supply of fresh, filtered, and tempered outdoor air throughout the home
- Recover heat from the exhaust air in winter.
- Help prevent excess dryness in the cold season
Don’t suffer from poor indoor air this winter. Improve air quality and overall home comfort with the addition of an air exchanger.
