AC Heating and Air Conditioning Services

I had a Trane HVAC installed back in 2014 by AC Heating and Air. Unfortunately, we had quite a few electrical issues that resulted in multiple tripped breakers, blown fuses, issues with the thermostat and the heat(3rd stage)never really working correctly. After about 5 years of that, AC techs said it was the wiring in the house and completely disengaged the third stage and suggested that we have an electrician out to install different breakers for the HVAC they installed. So this past week, the system had a leak in the coil and we had AC Heat and Air service the system(8/24/25) while we we debated what to do. We opted to replace the system. I got 3 quotes including one from AC heating and air (I am a real estate broker and always suggest getting multiple quotes). I ended up going with a different company because they were priced better, had better financing offers and a better warranty. They looked at the older system and said that there was nothing wrong with our wiring and that all of our issues were likely from a faulty heat kit installation or faulty heat kit (AC Heating and Air did the install). Lastly, we paid for our annual service contract 5/30/25 which covers two services per year. Being as we had a new unit installed by another company which provided a service contract with the new unit, I called AC Heating and Air to see if I could get a partial refund for the unused service and they declined. This is just my own experiencs so draw your own conclusions
