Wait, What Are HRVs and ERVs?

question-markUnless your true passion is HVAC, odds are, you probably haven’t heard much about HRVs and ERVs. In fact, it might just sound like a bunch of gibberish!

But here’s the thing: HRVs and ERVs are actually pretty neat. See, our homes are often tightly sealed up and, while this is great for energy efficiency, it’s terrible for indoor air quality! This is why these nifty little devices were invented — to give you the best of both worlds!

Below, we’ve explained why we think these systems are a worthwhile investment — that way, you can decide for yourself! All you’ve got to do is keep reading to find out more (and of course, remember to call our team when you need HVAC services in Morganton, NC.)

What are HRVs and ERVs?

HRVs (heat recovery ventilators) and ERVs (energy recovery ventilators) are essentially mechanical ventilators, but with a twist: the heat exchanger. This allows them to transfer heat between air streams, allowing for proper ventilation without sacrificing efficiency.

Simply put, during the summer, the HRV or ERV will transfer heat from the fresh, but warm, incoming air to the stale, but cool, outgoing air. This precools the incoming air so that your AC doesn’t have to work quite as hard. The reverse applies in the winter, as the system prewarms the incoming air, taking work off of your heater’s plate.

What’s the Difference Between an HRV and ERV?

HRV and ERV systems work similarly to each other in terms of temperature regulation. However, the major difference between these two systems is that an ERV, unlike an HRV, can transfer humidity in addition to heat.

What are the Benefits?

There are plenty of reasons to consider having an HRV or ERV installed in your home:

  • Better Efficiency: Perhaps the number one benefit of having one of these systems installed is better efficiency. When your heater and AC are energy efficient, it means you’ll spend less money on your energy bills.
  • Better Indoor Air Quality: With an HRV or ERV system in place, you won’t have to worry about allowing fresh air into your home. You can certainly expect your indoor air quality to improve.
  • Improved Comfort: Better indoor air quality combined with better efficiency means that you can expect your overall comfort to improve.
