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.
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!
We called service one when our heating wasn't working. They were able to get me on literally 2 hours after I called. It was the first time turning it on for the season. Brandon identified the issue with our flame sensor and had the problem fixed without any issues. He took the time to explain exactly what was going…
10 years warranty on parts and labor service is garbage and is false advertise on the warranty all your service is based on lies when you have a contact I will give your a poor rating on your service contract no star rating
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),…
On a cold, Wintery morning here in Chicago it is never fun to wake up to your furnace not running. Called Service 1 and they were able to make it out the same day (Wasn't necessarily expecting that) and the technician was able to quickly diagnose the problem and get me back up in running in now time. Highly recommend Service 1!
Excellent customer service was able to fix my heating issue the same day during a very cold day. Very friendly and knowledgeable.
Very professional, quick to respond and realistic with our options. Would definitely use again for both hvac and plumbing. With previous companies multiple people come out to look at the same problem before we’ve gotten any answers or time frame. With. These guys, they arrived at the very beginning of their time…
Brian was very knowledgeable and immediately identified the issue. The heating unit was fixed 20 minutes later and I would definitely recommend using this company.
On time. Informative. Great service!!!!
My heater went out at like 3:30am, they answered the phone and had someone dispatched reasonably quick. Fast efficient professional service. I would recommend this company to anyone.
Our furnace went out late at night and it's 3 degrees out. I haven't had it serviced before in our new home so I wasn't sure who to call. I tried another company first that said they did emergency service but I kept getting an answering service that said they would call back in the morning. I'm so glad after that I…
Mike Johnson came by on time and was very professional with excellent customer service skills and did a great job fixing my whole house humidifier. I would recommend.
Fast response and Quality work! I will definitely let my neighbors Know !
I hired Service 1 to shorten the natural gas service pipe that was sticking out of the floor in my kitchen. Their technician arrived promptly at the scheduled time, got to work immediately, and shortened the pipe. He also was extremely professional, and he followed social distancing and mask-wearing protocols. The…
They have always been reasonably priced. Quick to come out. Their estimate and final bill have always either been the same or one time less than the estimate. I highly recommend them toanyone that has heating or a/c problems.
I highly recommend Service1. We have been using them for a few years now and they are always on time, professional and reasonably priced. They have never over charged us, even for emergency last minute calls and they have always done quality work.
