Our serviceman, Brennan, arrived right on time, went right to work, stopped to answer a few questions and did a great job. He was knowledgeable, friendly and efficient, will definitely request him in the spring for air conditioner.Thanks.
Love working with service one and the service people are also very nice and friendly. Brandon is great to work with.
If it was possible to grade the service I received a ten out of ten I would because the service was exceptional. I was impressed with the professionalism of Vance the technician and the level of knowledge and expertise. He took the time to make sure I understood what he was doing and why. Also he shared tips every…
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.
Thanks Brennan! Amazing work!
Very professional. Neighborhood business. I will continue to use them when I have my furnace installed.
Service rep was great, he doubled checked everything to make sure my system was good.

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!
Branden was outstanding. Very knowledgeable, courteous and professional. We just switched companies to service our hvac needs and are glad we did.
I only did the clean and checks on the furnace, ac , and water heater so I cannot leave a review for larger jobs. Brandon was our tech and he was on time and very professional. He didn't try to upcharge anything and even put my hose away for me. I called on Wednesday and got an appointment for Saturday morning so mo complaint here.
Very professional. He was able to get here earlier than my appointment. I was able to my day started earlier.
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!!!
Most reasonably priced in the area. Service technician was very professional and friendly. Responded to my service request in a timely manner. Would recommend to all my friends and family!!
Super Super excellent service. We were scheduled for a 7PM call and they arrived at 9AM. Given options on repair, we took every one of them based off the excellent knowledge of the Technician explaining everything in detail. Thank You Service One!!!
Very polite and knowledgeable! A++ service! Would definitely use in the future!!
Service1 was extremely timely when we needed them. The free estimate was helpful to see our problem and quickly know our options. We felt the pricing was fair, and we were able to quickly get on their schedule for an installation. The team at install was extremely professional and clean. Would recommend. thank you.

Mike Johnston worked on our a/c. He was friendly, informative, and thorough. I highly recommend Service 1.
They are a very reliable and trustworthy company. I’ve used them for years and they have an excellent and knowledgeable team.
The technician came at the scheduled time. He was courteous and worked quickly to diagnose the issue and solve it. He also cleaned the unit. I always use Service1 Heating Cooling.
I just bought my townhouse so they were very helpful in helping me understand my ac and furnace a little better to make sure they last longer and run better.
The service technician Mike was excellent. He was very professional and detailed all of the options for potential repair and replacement but did not pressure into a solution.
I have used them several times and am very pleased with the service. All of the techs have been very polite and addressed any questions I had in great detail.
Randy was a great tech and installed our new humidifiers with a high attention to detail. Was on time, communicative in what we needed to do to avoid issues and was in and out in a reasonable time.
Great job on time and explained what was being cleaned.
Happy with service provided by Randy.
Very friendly and professional service. Service personnel fully explained details of the maintenance that was provided. He also walked me through steps to utilize newly installed thermostat.
I've been a repeat customer several times this summer and this company and their employees have provided quick efficient, and reasonably priced service each time. Polite, friendly, explained things in a way I understood and offered super quick resolution to my plumbing, AC and water heater issues. I would strongly recommend them!!!
Absolutely no one better in the industry. Had them out last year for annual maintenance and the tech mentioned I had a small leak in my refrigerant. He was able to top it off and lasted all year. I knew I needed to replace both AC and Furnace this year. Their prices were outstanding. The tech was in and out in 1…
