“I have been using One Call for over 20 years for both my home and business. I highly recommend them for their prompt service and excellent customer relations!”
Dennis Adkins, Owner AMSA

“Our 1994 air conditioning unit died on Tuesday, July 31, 2018 (right in the middle of the summer–you can’t beat the timing or the heat!). The next day, the folks from One Call Service were out at our home to look at the dead unit and to explain the various options we had to replace it. Amazingly, on August 2, the One Call crew was at our home with a new unit at 7:30 AM, and the entire 5-ton AC unit and new furnace were installed by 2:00 PM. My wife and I couldn’t be happier with the phenomenally prompt service or the new HVAC system.”
Mark Hagemeier, Residential Customer

“Sam Coulter has done my HVAC work for the last 25 years. He has taken calls all hours of the day and night, weekends, holidays, given reasonable prices on equipment. He has always been willing to spend time with the property owner ensuring they knew what the problem was and how to best resolve it. When there has been the rare callback, his crew has been quick to resolve the issue. Many of my property owners use him for their personal properties as well. I use his company for my personal properties and trust him completely.”
Mike Hoffman, Property Manager

“One Call Service Group was assigned by my home warranty to service my heating unit. I submitted the request late that night on 3/13/17 and they called me the next morning to set up an appointment for that afternoon on 3/14/17. They actually called back and said they could come earlier and they were in and out of my house in less than 30 minutes. They were very nice and fixed my issue and educated me on the issue. I had a positive experience.”
Kawannia W., Residential Customer

“My a/c quit working in June 2017. I called One Call late in the day and they sent someone out the next day at a time convenient for me. They confirmed what I already suspected, my unit was an old R-22 refrigerant system and it was not repairable. One Call provided a very reasonable estimate and installed a new unit. In short: They came when they said they would. They did what they said they’d do. They charged what they said it would cost. They were courteous and friendly. They did good work and didn’t leave any mess. My air hasn’t worked this well since I bought the place new nearly 16 years ago. I’m very satisfied.”
James K., Residential Customer

“I am a property manager, I have used this company for years. They are great, very dependable, and professional. I use them on my personal home and would recommend them to anyone.”
Courtney B., Property Manager/Residential Customer

David M., Residential Customer

“We are so thankful we found One Call! Our air went out in our pediatric therapy center over the weekend and wasn’t found until late Sunday afternoon. We called several companies only to find they were booked or not open. One Call was able to come out within the hour and had all repairs (needed new fan motor and compressor) completed quickly with no worries about a bill! ‘We will send you an invoice.’ The bill was very affordable based on other companies we have used in the past. We will use One Call when we have any commercial or residential needs! THANK YOU!”
Stacy A., Commercial Customer

“Super nice guys! The service is prompt and thorough! They didn’t spend hours trying to sell me a new condenser (mine is original to the house but still ticking). But you can bet when ours kicks the bucket I
know who I’m calling!”
