The Basics of HRV systems and ERV Systems

Both types of systems do one main job—they recover energy from a home’s exhaust air. This energy is applied to an incoming current of fresh air to either pre–heat it in the winter or pre–cool it in the summer. So without losing the conditioning you get from your HVAC system, you’re able to enjoy the intake of fresh air into your home.

The reason these systems have both become so popular is because of how homes are constructed nowadays throughout Richardson, TX and beyond. They are built very tightly and not able to "breathe" as well as they once did. This prevents heat loss and gain, making your HVAC system more efficient. But, without a properly installed ERV or HRV system, you could end up with stale air as a result.

Deciding Between an ERV and HRV System

As stated above, HRV and ERV systems are pretty similar. They both essentially serve as heat exchangers, which are installed in the ductwork of your home. They have their own duct, which extends through the wall and out of your home, so that they can bring in fresh air.

As air flows through the heat exchanger, one side flowing out and one in, these two airflows equalize each other’s temperature. The only thing that makes an ERV different from an HRV is that ERVs are able to transfer humidity levels, too. This typically makes ERVs the best choice for most homes in the Richardson, TX area due to our climate.

Examining the Benefits

Whether you choose a heat recovery ventilator or an energy recovering ventilator, as a Richardson, TX resident you can benefit in a number of ways, form having a system that pre–treats incoming air to maximize energy efficiency.

  • Better HVAC System Performance: You may not feel the need to adjust your thermostat as much with an ERV or HRV system in place.
  • Lower Energy Bills: When you use your HVAC system more efficiently, it has a significant impact on your utility bills.
  • Better Air Quality: You’ll no longer have to contend with stale and stuffy air.
