Why Charleston Homeowners are Installing Heat Recovery Systems



If you’re familiar with South Carolina weather, you know that the long and sultry summers are often followed by frigid winters. The colder months often necessitate retreating indoors until any semblance of warmth returns in spring.

A home without proper ventilation is not only uncomfortable, but also prone to moisture buildup that creates unhealthy mold situations. This can be especially challenging to manage when heating costs are high and it’s too cold to open the windows. Fortunately, an HRV (heat recovery ventilation) system provides the best of both worlds.

How HRV Systems Work

In short, heat recovery ventilators extract damp, stale indoor air before replacing it with fresh, filtered air from outside. An exchange core collects heat along the way and transfers it to the incoming air stream. This efficiently raises ambient temperatures, which saves money otherwise spent on heating bills.

The two air streams are separated to prevent contamination and positioned specifically in areas where moisture is high, such as the kitchen and bathroom. Following is an overview of the key benefits this system offers.

  • Adjustable remotely
  • Better air quality
  • Balanced room temperatures
  • Eliminates contaminants
  • Reduces wasted heat
  • Lowers energy costs

Not convinced? Let’s take a closer look at why Charleston homeowners are installing heat recovery ventilators.


Where are HRV units placed? In most cases, ventilation systems are installed in the attic, plant room, or void spaces that are out of sight. The pipes are then distributed throughout your home. Both new and old buildings can be fitted with an HRV system, although they work best in modern structures that are adequately sealed.

While DIY kits are available, you can always opt for professional installation. By working with an accredited installer, you can have a custom system designed based on your requirements. Head over to for more information.

Health and Hygiene

Now more than ever, a major draw of heat recovery ventilators is their ability to create a healthier atmosphere in your home. Air circulation plays a significant role in the spread of dust, pollen, allergens and respiratory illnesses. Having a constant flow of fresh air prevents the growth of mold and mildew as well.

Drafts and Leaks

HRV systems also eliminate the reliance on air leaks that, while helpful for ventilation, put pressure on boilers and other heating solutions. This of course drives up your utility bills, not to mention lacking any of the air filters that HRVs use to keep out particulates. With a heat recovery ventilator in place, you need not have any drafts in your home.


Another advantage of HRV systems is that they’re appropriate for all climates. This is because despite their name, heat recovery ventilators can also be used as air conditioners in the summer, helping to clean and cool indoor air on hot days. Plus, they markedly lower humidity levels, which can save money otherwise spent on a dehumidifier.

It’s clear that homeowners have good reason to install a heat recovery system. Be sure to consider it moving forward.
