You want cleaner fresher air inside your home or business? 

Breathe fresher air and feel more comfortable with an ERV from Hess Air.

ERVWhat is an ERV?

An ERV or Energy Recovery Ventilator is a whole-house ventilation system.


  • An ERV takes dirty air out and brings fresh air in.
  • As the ERV pulls fresh air into your home, it conditions the air and makes it easier for you to maintain perfect comfort levels.

Here’s a fact - The air quality in most homes needs improving.  So much energy saving focus has been toward sealing the house from air leakage, that many homes never actually circulate any “fresh clean air” into their homes.

That’s pretty gross if you think about it.

Add some pollen to the mix, and some extra heat and extra humidity that we have so much of here in the Rio Grande Valley of South Texas, and improving indoor air quality becomes even more important if you want to keep your home or business healthy.

Hess Air Indoor Air Quality Tip:

Add an energy recovery ventilator (ERV) to your HVAC central air conditioning system and make a huge impact on the effective ventilation of your home.  Every home should have good ventilation in order to get the stale air out and fresh air in.  Poor ventilation leads to a buildup of polluted air within your home.  Dirty air in your home is a major cause of health problems including aggravating the symptoms of asthma and allergies.  Proper ventilation provides your home with fresh, clean air, increasing indoor air quality and thermal comfort.

HVAC means Heating Ventilating and Air Conditioning.  The V is for ventilation, and without an energy recovery ventilator (ERV), you’re ignoring this critical component of indoor air quality, comfort and health.

An ERV is an easy and smart way to make your Rio Grande Valley home cleaner and much more comfortable.  Adding an ERV in our hot and humid RGV climate can make a big difference in how you feel every day in your home or business.

Here’s why you should ask about an ERV system from Hess Air:

  • An ERV gives your home cleaner air to breathe for your families better health
  • A Hess Air ERV improves your control over the humidity level in your home, and that feels so nice.

“My system already has a filter. Is a filter the same as an ERV?”

No. A Filter is NOT an ERV. It’s just a filter.

  • A filter does not create fresh air; it just runs the same air through over and over and over.
  • If your filters get dirty quickly, it’s probably a good sign that you need an ERV (energy recovery ventilator).


Energy Cost Savings.

An ERV can actually help you reduce your cooling costs.

With the good ventilation that an ERV from Hess Air provides, you’ll have less humidity inside.  Dry air feels cooler than humid air, and most people don’t keep their temperature settings as low once their ERV is installed.  When you raise your air conditioner’s thermostat temperature, you save energy.
