Where do I start. The builder that built my house spared EVERY single expense possible. The A/C unit was no exception. As the years went by, it started becoming less and less efficient. My power bill was the first indication. Every season the bill went up.Earlier this year, the heat pump was freezing up. The emergency heat didn't work either. I got it fixed, but it cost me for the labor. The parts were still under warranty.The same exact thing happened this season. I had enough of throwing money at this system, so I began my search for a company to replace it. I got plenty of suggestions from various places, however, I eventually when with Estes Heating & Air. It was the best decision I could have made!I met with Jimmy and he quoted me a Bryant (made by Carrier) system. There were some supply chain issues, so I had to choose a better system. They were super generous giving me the best deal possible!To make a long story short, which this review is not, all the shortcuts that the builder took were fixed by the most professional techs I've ever seen.Everything that could be replaced, was. I couldn't believe it!!!!! The entire process was symphonic. The only evidence that any work was done, is a warm and comfortable house.It's right before Christmas so I'm going to finance it through Alabama Power for now. I may pay it off early, not sure. TBH, my power bill was $250 - $300/mo over the summer. I'm guessing I'll save about $100/mo because this new system is ultra-efficient.Bottom line, I'm VERY happy and HIGHLY recommend Estes Heating & Air.
