Customer Testimonials

Very grateful that Nick and Cameron cane out to help us out. We were drowning in sweat with no AC for a couple of days in this crazy heat. They came out and took care of the problem quick and helped us cool off.

In the Design/Construction business for 42 years but now retired. I have dealt with HVAC companies all over the world in my business. After working with several of the large HVAC companies in San Antonio over the past 20 years, I decided to find another smaller contractor to look at a problem that I was having with one of my AC systems in our home. I called Elmer's and a technician arrived on time, the very next morning. Nick Venne was very professional, found the problem almost immediately and worked closely with me on developing a price and execution plan for repair. His work was very professional and completed in a timely manner. We will certainly use Elmer's for our HVAC needs in the future. Excellent repair and very timely.

Elmer’s is a real honest business that cares for their clients and has awesome people who come out to check our issues like Kyle did.
He was sweet and went over and made sure I understood what I was getting myself into and explained everything.

Air handlers are an integral part of any HVAC system. Usually, an air handler is a large metal box inside your home (often in a closet), containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators and dampers. Air handlers generally connect to ductwork that distributes the conditioned air through the home unless attached to a ductless split system. If even one of these parts is functioning poorly or failing, your entire air conditioning system, including the air handler, will not work.

At One Hour Heating & Air Conditioning, we make our clients' comfort our utmost priority. We've specialized in residential air conditioner replacement and installation in San Antonio and surrounding areas since 1998, so you can expect complete customer satisfaction on every project - big or small.

What is a Heat Pump? A heat pump is different from a furnace in that it doesn't create heat. Heat pumps simply move warm air from one place to another, whether that is moving hot air into or out of your house. It's ability to run in reverse means that it can both heat your home in the winter and cool it down in the winter. What is a Air-Source Heat Pump? An air-source heat pump transfers heat indoors from the air outside in the winter and does the opposite in the summer. An air-source heat pump makes the most sense for homeowners living in warmer climates.
