Love working with service one and the service people are also very nice and friendly. Brandon is great to work with.
Used Service1 for the annual servicing of our AC system and it was well worth it! Branden came out and performed a thorough and detailed servicing of our system, explaining what was necessary and what wasn’t. Highly recommend this company and plan to use them again in the future!
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 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.
Been using Service 1 for twenty years, great work at a fair price. Recommended!
We are extremely pleased with Service 1and their service technicians Branden & Mr. Morales for their exceptional work. Highly recommend them for all your heating/ac/plumbing needs. Reasonable, prompt & professional.
Brandon arrived within the designated time slot and went right to work. Very Professional
Everyone we've dealt with has been amazing! We have used Service 1 for plumbing and HVAC both and have been so impressed!! I recommend them 100%! Every technician has been so professional, cost efficient, and extremely knowledgeable. I would recommend Service1 to everyone!
Called in the morning and they were able accommodate on the same day! Jimmy and Brandon were very helpful and knowledgeable really appreciated the quick friendly service.
Have used the company 3 or 4 times now. All for HVAC work. And once to install a sink/faucet and all Were very responsive and knowledgeable. They give you recommendations on what to repair but leave it up to you and don’t feel pressured like a car salesman. Came out last year with in 2 hours when furnace went out…
Showed up as scheduled and did quality work.
Branden Schuster just came to our house and he was AMAZING! We are new homeowners and have no idea what is what. He was so through and he even explained each part and what they did, how they function, etc. AND he saved us $800 from an Air Duct company who said we had mold when there was none! HIGHLY HIGHLY RECOMMEND!!!
They were very quick to service our broken heater in December. So, it was a no brainer to schedule an AC inspection and cleaning in the Spring. Brandon was very respectful of our property and told us what he did and what we can expect coming up.
Patrick and Wyatt are great. Arrived earlier than scheduled, courteous, professional and efficient. Great service on a very cold Xmas weekend. Thanks 🙏
The technician provided professional and quality service during the AC maintenance. I was provided information and options for replacing my thermostat. I will definitely be calling them for wiring and installation of digital thermostat.
Randy was timely and professional! No complaints.
I had a basement hot water copper pipe and a water heater pressure relief valve water leak. Called Service 1 plumbing & heating and got me on the schedule quickly. Service plumber "Al" came on time, replaced the hot water pipe, pressure relief valve, and expansion tank in 1 visit. He was quick (1.25Hrs),…
Cannot recommend this company enough! They came out earlier than anticipated, provided us options for how best to service our AC unit and it's already working better. We tried them out because we got a coupon and were pleased.
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!
