Best Automation Solutions in San Antonio TX

I wish they gave me a coupon or something for my review like other service companies, but I feel compelled to write one anyway as this is the 3rd HVAC repair company I have tried in San Antonio and they were by far the best. I won't say the other companies names but I tried one of the biggest companies in SA the first time and a company run by one man the second time. The tech I called from the big company cussed in front of me, bad mouthed the home inspector, and charged me around $400 to replace a $20 part that ultimately needed to be replaced a few months later as they didn't diagnose the issue correctly. The guy that runs his own company wasn't friendly at all and when I asked him questions about what he was soldering/brazing he seemed offended and instead of answering my question told me that I was free to inspect his work after he was done (I was interested because I tried to do the repair myself and couldn't, so I wanted to see how the professionals did it). The techs from Comfort Air took the time to explain everything and they were friendly. They also got to my house very quickly. Oh, and the dispatcher was nice as well. After my first two experiences I was legitimately convinced that the HVAC repair industry was a total scam but you guys have restored my faith. Thank you!!!!
