I’m never disappointed with the service from A-1. They installed my system and have kept it running optimally ever since. Ashley performed the most recent service and she did a great job. She was efficient and friendly.
Ash was great! She answered all of my many questions and was happy to do so. She was easy to talk to and great with dogs!
Ash was very professional in servicing my unit. I would suggest one thing for the company. On days like today when it’s rainy and wet, shoe or boot covers coming into the Howe would be an excellent idea

Ash was very knowledgeable and precise in communicating and working on my AC. I felt confidant she knows her job well and worked to check all in my system to be sure it was working at its best. Thank you Ash.
Dear A-1 Certified, I want to take a moment to praise the exceptionally professional and proficient job that Ash, your technician, did during my service call today. As you probably know I have been a customer for many years and I have not always been satisfied with your service. On this occasion I can say that I am extremely pleased. Ash took the time to explain the work that she was doing and clearly demonstrated her outstanding knowledge of the equipment and its proper operation. Unlike previous visits from other technicians, Ash was very thorough and did not need to be reminded of any maintenance items to be performed. Ash is a great asset to your company and I hope that you are able to retain her for many years to come. Regards, Norman T. Ford mobile: 865.696.8998
Ash called before arriving, was spot on with her arrival time. She introduced herself when she arrived, said hello to our welcome committee Shitzhu, which is important to us ;) Briefed me on what she was going to be doing. She was extremely professional, polite & got to work right away. She went over paper work I needed to sign, explained everything checked out to be working properly & ook garbage filters with her. From what I could see, Ash did a great job! The pricing has nothing to do with Ash, that's determined in office.
Thank you to Ash T who is professional, knowledgeable and friendly. You can trust this tech from A1 Certified - she’s a 10!
Ash did a great job - thank you!

The HVAC service I’ve been looking for for 20 years! Thank you
Josh and Tommy went above and beyond to replace my worn out heat pump with a sleek and efficient new dual-fuel heat pump. They were on time and worked all day in hot and humid weather.
Stayed in contact regarding a repair that took a few visits to get done, but Josh and office staff always followed through.
