"Trinity was the most reasonably priced contractor to install my smart thermostat. James was really helpful and also helped diagnose some additional issues that were going on with my system while he was here, but in no way made me feel pressured to do additional work right now. I now know what to look for to avoid issues in the future and will absolutely call them first when I'm ready for a new air conditioner!"

"Air Tech was great. I would HIGHLY recommend. I initially had 2 other companies besides Air Tech come out for a replacement estimate. Price wise Air Tech was right in the middle but were doing a lot more than the other 2 quotes I got. For example they were changing the copper refrigeration lines, which the other 2 weren’t going to do. When I called the other 2 companies to add the lines in there was going to be an additional $1500-$2000 charge. I’m very pleased with this the work that was done by Air Tech"

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."
