If you own a home, you’re probably bracing for higher monthly energy bills this summer as temperatures rise and your air conditioner is put to greater and greater use. But just because you pay more during the summer doesn’t mean that you should pay more than is necessary. Some of that can be mitigated with common-sense tips such as setting the temperature a little higher than you might otherwise. But you can do much more with the timely installation of an upgrade to your existing air conditioning system. Now is the ideal time to install such a system since the summer has not yet begun in earnest.

Among the types of updates you can consider is an energy recovery ventilator, or ERV. It’s installed in your attic, and can contribute hugely to the energy efficiency of your home. We’ve provided a breakdown on how it all works below.


An ERV and its cousin the heating recovery ventilator, essentially consists of two lengths of duct, each including a fan. One fan blows air out of your home, while the other pulls outside air into your home. the ducts never touch, but a heat exchange connected to both of them ensures that the temperature of the incoming air is the same as the temperature as the outgoing air.


That may feel like a lot of effort for very little effect but in fact, an ERV does a number of beneficial things for your home. First and most importantly, it helps keep the air fresh in your home when you don’t open the doors or windows very much. We tend to button up our homes in the summertime, when the high temperatures and higher humidity mean you need to keep your doors and windows closed. That can lead to a stagnant, stale feeling in the air, as well as encouraging the circulation of germs and bacteria. With nowhere to go, they can easily spread in your home, passing illnesses on to various family members and ever worse.

An ERV can help curtail all of that, removing older stale air in your home and replacing it with fresh air from outside. Your home will feel fresher and cleaner as a result, and don’t be surprised to find instances of colds and other illness dropping down.

In the process, it provides another huge benefit to your home. As it swaps the air out with fresh air, it helps ease the strain on your air conditioner by helping your home better retain its cool temperature. The same thing occurs in the winter when your home has to retain heat. In both summer and winter, that helps reduce the cost of your monthly energy bills, as well as reducing the wear and tear on the system itself and lowering the chances of a more serious breakdown.
