Have worked with A-1 twice: to fix a furnace and a loose dryer duct. Great experience both times: fast appointments, excellent work, clear communication. Would definitely recommend.

A1 Heating and Cooling installed a replacement two-stage, four-ton HVAC system at my home late last year, 2023. Miguel and his team did a great job. His whole team showed up and were very professional. They were quiet and they cleaned up after themselves each day. Each of Miguel's teams worked diligently the whole time they were there on all the tasked assigned to them, including upgrading my electrical disconnect near the outside condenser coils. I doubt the smaller companies would have done all this. I feel that some companies would have cut corners, but A1 didn't do this. And the price was actually lower than some of those other companies. So it was a great value. After Miguel was done, I looked upstairs in the attic at the air handler/evaporator coils area, and the final result looked like something out of a brochure. All the aluminum foil tape, etc., was applied with care, and it showed. It was not at all sloppy work like you get sometimes with contractors. Miguel even fixed something in one of my zones that was not right. He increase the size of the branch ducts to my smallest zone to a ten-inch duct to increase airflow to that small zone. And it was done at no extra charge. A couple months after all this fine work was done, I noticed a few action items that I thought might improve the job. A1 sent Francisco over to work on it, and his professionalism and attention to detail was excellent also. It turns out that the problem was my fault. I just needed to be more aggressive with swapping out the filter. He showed me this fact without trying to make me feel dumb about it. In the end, Francisco even made a modified filter for me because the original installers (not A1) did not make the intake register properly. The "box" for that register was not made square, which means that *no* off-the-shelf filters fit. I need to fix that register, but Francisco created a filter that will work until I get that fixed. All this makes me want to give that job to A1 Heating and Cooling also. Good work.

Vent was clogged up - they removed an Easter basket of fuzz-cotton and cleared it...

Bryce did an excellent job with the furnace tune up. He is knowledgeable, friendly, and efficient. I was looking for a company for routine HVAC maintenance. A-1's prices are competitive. Looking forward to going with this company next year.

Bryce Pierce did a great job at maintaining our furnace! He found a vent problem which could have been hazardous (CO backup) and a drain problem which could have created an expensive leak in our attic. He returned a 2nd time to replace a blown fuse at no charge. We appreciate his diligence, clear explanations and knowledge!
