A/C Company Reviews and Testimonials

The service was excellent: all lines blown, refrigerant recharged, filters changed. The techs also took great care to cover their shoes every time they entered the house in order to prevent tracking dirt onto our carpets. Everything was very professional and I feel very confident going forward that Northside is a company my wife and I can genuinely trust.

Just had system check and a weird noise checked and fixed. Very impressed with Northside! The technician was excellent at diagnosing and explaining. Highly recommended!
