I had a problem with my Air Conditioning Control and Thermostat. I’m a fairly technical person and couldn’t figure it out setting the thermostat. The compressor would not start when cooling. I set the temperature at 73 degrees F. When indoor temperature increases to 75 degrees F., the air supply fan would start but the outside condensing unit compressor will not start. I observed the compressor would start only after it was 4 degrees F. or above the setpoint. I called Affordable Heating and Air and spoke to Sara and explained the situation. She was very courteous and showed me a lot of empathy and compassion about my frustration and problem. Sara assured me that she would send Juan to diagnose the problem. A couple of hours or so later Juan came to my house and he was very friendly and eager to see the controls to see what is going on, as I have a Venstar T1800 thermostat. Juan was very friendly, courteous, and knowledgeable and checked all the install connections to my furnace air handler and condensing unit. The connections seemed fine. It was a bit complicated as my condensing unit was a heat pump able multi-stage compressor. My thermostat, although compatible, was not wired to work with this system. Juan along with a call to Jimmy, Affordable Heating and Air’s Tech Manager, diligently, and thoroughly diagnosed the problem texting photos and diagrams of the system. After several hours of troubleshooting and diagnosing, they were not only able to identify and fix the problem via wiring corrections, but ensure that the multi-stage compressor on my condensing unit performed as it was designed. Jimmy spoke to me on the phone and thoroughly explained everything to me. Wow, I am blown away, and so pleasantly surprised at the level of service I received from Juan and Jimmy. They are both so professional, courteous, and so knowledgeable. I enjoyed and appreciate talking to Jimmy as I like technical things about HVAC and he is a walking encyclopedia and wealth of information regarding HVAC and wiring diagram schematics. Juan and Jimmy not only provided me exceptional customer service, but ensured my HVAC was working as designed. I strongly recommend them.
