Wow, these guys are legit. Zach came out and diagnosed my heating issue right away, then fixed it on the spot. He was incredibly kind, explained everything in a way that actually made sense, and even gave me a few maintenance tips so I can stay ahead of things. Solid guy, great service, and the whole visit gave me a lot of peace of mind.

Impressed How Soon I Got on the Schedule
Impressed how soon to get on schedule and have technician arrive. Technician explained everything he checked and showed me issues he found. I did not know I had an issue with my heater as we only ran AC all summer. Turned out I had 2 birds fall into exhaust blower motor. So glad Zack came out before we would have switched heater on for the season.

I Highly Recommend Quality First
I called Quality First at 3:30 on a chilly Saturday afternoon, and they arrived at 5. Our furnace had been down one day, and without their help it might have been a couple of days more. An hour after their serviceman arrived everything was working, and the charge was quite reasonable. I highly recommend Quality First.
