If your home was built in the last 10 – 20 years, it’s probably pretty efficient – airtight doors, thermal windows and no gaps whatsoever. While this is good for maintaining HVAC efficiency, it doesn’t exactly facilitate fresh air getting into your home and moving stale air out. In fact, all of these energy efficiency techniques are among the leading causes of poor indoor air quality in most Maryland and Washington, DC homes, resulting in indoor air quality that is up to 100 times worse than outdoor air! You could keep your doors and windows open to let fresh air flow in (along with all the heat, humidity and assorted nasty pollutants that might be out there too), or you could install an air exchanger as part of your HVAC system!
What is an air exchanger?
An air exchanger is basically a ventilation system that pulls humid, stale air out of your house, and replaces it several times a day with fresh air from outside. To do this, the air exchanger draws air in from an open port facing the outside of the building. The air moves into a chamber (the exchanger), where it is passed over by the stale air coming from the inside of the house. The air from outside passes through a filter and is then distributed through your house, while the air from inside the house is expelled outside. The air exchanger can work independently or can be connected to your existing forced air HVAC system without compromising the efficiency of any of your appliances. Best of all, the temperature of the air can usually be saved from the inside air to the outside, meaning that you can retain almost all of your heating and cooling energy even while moving from inside to out.
What are the benefits of installing an air exchanger?
The benefits of installing an air exchanger in Maryland are numerous. You can think of it like this: air exchangers perform basically the same function as electronic air cleaners, with the added bonus of bringing fresh air into your house and moving germs, odors, bacteria and other pollutants out. You can even outfit your air exchanger with a HEPA filter to trap any incoming particles and pollutants before they can get into your home’s air supply.
