Here is what our customers have to say about us…
Efficiency and caliber of personnel doing installation of our air conditioner and heater was impressive. They worked very hard even though they had 102 degree heat to work in that day. This company’s efficiency is amazing and they’ve done an excellent job and we would certainly recommend them to anyone.

The quality of the installation was exceptional and was finished in a timely manner. I expected the install to last the whole day but instead it was done in several hours. The installer completed the job quickly and professionally. He did not try to force any unnecessary parts or labor on me.

They arrived promptly at the time they had informed me. Minimal interruption to my household activities, they completed the work without disruption. They maintained clean working area and left my house exactly as it was when they entered. Installers answered all my questions, explained maintenance and operation. It was a pleasure to feel as though a contractor was not out to take advantage of you or rip you off.

Joe & Dan were very knowledgeable and professional. They worked all the time they were here. The job was completed and the area was cleaner when they finished than when they started. They did everything as promised and I am very satisfied. Everything is working as it should be. You will be very lucky if you hire them to do your installation. A-1 Guaranteed is fair and great at what they do.

We are glad we chose A-1 Guaranteed first because it is local and easy to get service or information if needed. Also, we are glad they are members of the Better Business Bureau. We found Richard and his workers very courteous and knowledgeable of the Trane product they installed.

It is so nice to have every room cool. It doesn’t take long to get cool either. We are really enjoying our new central air and can’t wait for winter to enjoy our heat. Richard and his crew were great. They were neat, very polite and trustworthy. We would recommend them highly. As a matter of fact, we already have.

Richard was quick to come and look at the job when I called. He took great pride in the work that needed to be done. He came by to check on how the job was going and all of his workers were very friendly and helpful. Joe was very nice and helpful, he went over everything with me to make sure I know how to work everything. Joe went the extra mile to build a box so my heater would work better. I would use him again if I wanted another job done.
