Excellent service




Review of A-1 Certified Service, Inc

Had our biannual maintenance on hvac. Good report but many wait until a problem occurs before ask for service. They try to save money. You can save by scheduling maintenance checks. Well worth it. Our Service tech was very professional and completed the service in a timely manner.

Service




Review of A-1 Certified Service, Inc

I appreciate the way Josh handled our repair. We have been experiencing problems ever since it was installed. Twice due to zip ties that should have been cut when installed. We have put more money into this system than we should have and several times due to the installer. I appreciate the way Josh and A-1 did their best to make it right. Josh went above and beyond and was very courteous. Thank you.


Friendly and Knowledgeable Staff!

Review of A-1 Certified Service, Inc

I had basic air sealing done at my home. Built in 1925, it’s very drafty and I’m hopeful the air sealing will make a difference in my KUB bill. Everyone I met with the company was personable and knowledgeable.


You always send the best!

Review of A-1 Certified Service, Inc

My heat pump went out twice in 72 hours during the extremely cold weather. Matt got it running again,took the time to research the history of problems and arranged for a warranty replacement of the heating unit. He was very professional and took the time to explain what he was doing.


Wonderfully patient experienced workers!




Review of A-1 Certified Service, Inc

I didn’t understand how they were going to fix my ducts and they explained it to me in layman’s terms. They cleaned up after themselves and everything looks great! I had some additional questions and they told me other services they offered. I use these guys for regular maintenance too. Will continue to call on them as this old house grows older!
