A-1 Heating and Cooling
Heating & Air Conditioning Contractors in Union City, CA
Average rating: 5 out of 5 stars10 October 2014
“I had a whole new furnace, ducts and air conditioning unit installed by A-1 The workers showed up when they said they would, were very respectful and cleaned up each day after the job. It took them only 3 days to do the full installation. There was a problem with one of the A/C parts and the owner sent someone right away and ordered a new part to get the problem fixed. I was not only impressed with the initial work, but you truly know a company is good with how they handle any problems that arise afterward. I would highly recommend A-1 to anyone looking for Hvac service!”

BAYHILL HEAT & AIR
Heating & Air Conditioning Contractors in Union City, CA
Average rating: 5 out of 5 stars7 May 2020
“We renovated a "fixer" into owner's area, plus an ADU. We wanted super energy efficient systems, and fool proof, so went with heat pumps. Bayhill's quote was lower than some, and it was clear they "spoke heat pump" better than others. Was pleased with their work, their pricing, and their knowledge. Highly recommend BayHill Heat & Air.”
