This company is officially “My HVAC” go-to Company. Always very responsive to request made for Help. They scheduled my appointment and fortunately was able to move appt earlier due to another cancellation. With upcoming heat wave in couple days and Guest (of course) in room that required the (split air) hvac fix I’m grateful Evan had us up and running within minutes. I’m soooo appreciative of the professionalism and expertise of this wonderful company.
Again, Thank you all sooo much! -

Our old AC was having issues, and we had no AC on a very hot day. 100% Guarantee Heating and AC came out to diagnose the problem, fix it, and give good advice on moving forward. Ryan was great! I would recommend using them.

Speedy scheduling, fair pricing, quick trouble shooting and stable repair work. Second time in a month (different houses) that I had to call on "A 100% Guarantee" and they did great again. Last time they came out in <4 hours and were right on time and had the issue identified fixed and back our the door in <20 minutes. This time (moved to a new house) and I called around 4pm and they were to fit me in the next day for a 1-3pm slot. They landed right in their slot, around 1:45, and I got a text confirmation of the appt. And when he was then en route. I had Evan both times, and again he identified the issue, swapped out a capacitor this time, for a just fine cost per my internet research, and was back on the road in a timely fashion. Friendly and easy to work with, and better availability than the 5 shops I called the first time, so Evan was the first guy I called the second time.
