The National Difference

national_truckCincinnati Heating and Air Conditioning Services

National Heating and Air Conditioning is not your typical heating and cooling contractor. We employ a number of practices that set us apart in the HVAC industry that we believe will help you get a sense of who we are and how we do business.

“The National Heating and Air Conditioning Team did a whole house energy audit for us and found that our return air duct was pulling attic air into our home, causing our air conditioner to run constantly on hotter days. They also noticed that certain areas in our attic were not insulated properly, causing hot and cold spots in certain rooms. After giving us a few options to fix the issues, they proceeded to air seal the return duct, insulate the small areas of the attic, and seal the duct work, leaving our home more comfortable and energy efficient.

The guys used white drop cloths and booties throughout the process, and were very respectful of our home, which was very much appreciated!”

A Thorough Process

We are in the heating and air conditioning business to work hard, and to resolve complex problems for our customers’ comfort, safety, and energy efficiency as it relates to their home comfort system.
