Phoenix's AC Breaks in the Middle of the Night.

Get in TouchA Family Business Built on Showing Up
Kowalski HVAC was founded by Stan Kowalski in 1998, and his son has run the company for the past eight years — keeping the same hands-on approach that built our reputation one job at a time. We work on homes and smaller commercial spaces across Phoenix, and nearly everything we do comes from word of mouth. That means every call matters to us personally, not just professionally. We're licensed, bonded, and insured, and every one of our technicians holds NATE certification — the highest standard in the industry.
What We Do
From a quick tune-up before summer hits to a full system replacement, we handle it all — for homes and small businesses up to 5,000 sq ft across the Phoenix area.

After-hours emergency fee: $149 + parts
AC Tune-Up
A thorough seasonal check-up before the heat arrives. We inspect, clean, and test your system so you're not scrambling for repairs in July.
