- CSChris Spencer1 day ago5.0Had our AC go out suddenly. Jimmy was here just a few hours later and had our AC going again in no time. They also have helped us resolve a challenge issue with our furnace, even calling in the manufacturer to address an issue. Great service. We'd never call anyone else.
- JWJeff Webb2 days ago5.0Jimmy was great and very helpful, and fixed our issue the same day. Took the time to explain everything and was just great overall.
- JLJennifer Loveday5 days ago5.0The A-1 team is always quick to respond and provides great service. Technicians Jimmy and Stuart are friendly and helpful!
- RHRobert HierholzerMay 11, 20265.0We were very pleased with the work done on our HVAC. The technician was courteous and professional. I highly recommend this company.
- BFBruce La FetraApr 24, 20265.0Zach and the whole team at A-1 Certified are great. My A/C seemed unbalanced. They spent quite a bit of time checking temperatures and measuring air flows. They couldn't find a problem, perhaps because the weather was mild. Zach gave me a few things to watch for when the weather gets hotter and said he could come back. When A-1C insulated my attic and garage, they did a great job then. 2 for 2.
