Service One installed my system 11 years ago and has taken great care of it ever since. I would not go with anyone else. All of the technicians that have come out have been polite, courteous, and professional. 9/5/26: John came out to replace a capacitor and some wiring due to a hungry mouse who had its last meal. Work was completed efficiently.
Service 1 Technician re-leveled and moved my A/C unit which had severely tilted. The work involved was completed in a professional manner .
Service Technician was professional, friendly and made sure I understood what the issue was. He made me aware of additional service/maintenance packages that they offer. I would highly recommend Service 1.
Service 1 took care of our central air unit today. They sent a technician, John, within a reasonable time frame. He was professional, knowledgeable, explained the problem and the "fix," answered all my questions, and didn't hesitate to get right back to work when stung by a bee! Great attitude and customer service.…
97 degrees and the AC went out. After unsuccessful attempts going thru our home warranty service we reached out to Service 1. Why we didn't in the first place is a mystery as we have always had excellent service from them. Shout out to Mike our tech who got us up and running as well as explained the importance of…

Mike was great! He communicated well about when he would get to our house and was able to tell us what the problem was quickly. He was honest and professional. He was able to fill our refrigerate and get us back up and running quickly.
We had a fabulous experience. Our technician was thorough and explained everything on our level! We are forever customers!
The service person was exceptionally pleasant and efficient. Provide a good explanation and repair. Same was true of the customer service person who set the appt. I had to cancel and move the time twice. She couldn’t have been nicer or more accommodating.
My daughter recently bought her first house and during the home inspection we found there was water dripping from the plenum. Service 1 installed the system in July of 2018. They came out and took a look and took care of the problem at no cost. They could of easily just said it is beyond warranty. But, they took…
