Check out what homeowners are saying about A-1


Worked quickly and efficiently

“Brad and his team were quick to respond with providing an estimate, scheduling, and questions we had about the placement (and safety) of the unit. On installation day, a team of three guys worked quickly and efficiently, and they cleaned up after themselves. I highly recommend A-1 for any heating and cooling needs.”

– Lydia H., San Jose, CA

Very professional and punctual

“Brad and his team were very professional and punctual. If there is ever an issue, the team comes out immediately to fix it. Would definitely recommend them to anyone who is looking for heating/cooling services.”

– Jessica F., Los Gatos, CA

Respectful of COVID precautions

“We looked into getting several bids, and finally decided to proceed with A-1 Heating and Cooling through the Lowe’s program because their prices are competitive, awesome customer service and most importantly they were respectful of COVID precautions.”

– G. N., Fremont, CA

Had someone out the same week

“My grandmother’s AC unit was not working properly, kept overheating and popping her breaker. Gave A-1 a call and they had someone out within the same week. The two gentlemen that performed the service were super cool and polite.”

– Alex P., Cupertino, CA
