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
Technician appeared to be knowledgeable and courteous. She arrived in a timely manner and explained what she had done and why. Appointment for replaced part was scheduled same day of service.
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!
Ashley was very prompt in arriving at the appointed time and very courtesous. Checked out our system and gave me an update. Great service.
Nice to see a woman doing a man’s job?? Ash was very professional, knowledgeable, thorough and very nice. She’s doing her job and I commend Ash and A-1 for doing the right thing, hiring her! Thanks!
Technician was very friendly and knowledgeable!
Josh B was prompt, very fast, very courteous. I could tell right away that this young man was a hard worker and knew what he was doing.
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.
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.
Josh was professional, polite, and quick to solve the problem with my ac.
Josh was professional and friendly, quickly diagnosed and fixed the problem.
Did a good service and explained everything he was doing.
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.
We received great service with a very quick response time! Tommy and Tyler were very professional and helpful. We will definitely use them again and would recommend them to others!
