A/C Company Reviews and Testimonials

Fantastic!!

★★★★★
5 5 1
Fantastic!! From the start working with Chuck to the follow-up getting the system tuned has been amazing. We had 5 other companies come out and they couldn’t get our old downstairs unit running properly. Northside came out replace a $150 part and there you go. We have made it through 2 Texas summers and no problems. The new system they installed is spectacular and they really went above and beyond to get it right for us. My wife raves about these guys. When we build our next house they will be putting the AC in. Only company to go with in our opinion.

Very Satisfied

Serviced (2) AC units and added refrigerant to both. We were very satisfied by the work performed and the professionalism displayed by the technician. We have now contracted them to replace some duct work to improved air flow into a couple of bedrooms.”
