One Hour Heating & Air Conditioning® of Elk Grove 3540 Swenson Avenue, St. Charles, IL 60174

"I will always recommend One Hour Heating & AC to anyone in need of hvac assistance. They are prompt, thorough and always come through. Jose has been our technician for years and he has always taken excellent care of us. I'd give more than 5 stars if I could...they are that good."

"I could not believe how smooth the install went and as promised within 2-3 hours including a new thermostat. Joe was happy to answer any questions and helped with setting up the app on my phone. I could tell the entire team knew exactly what they were doing. Another aspect I truly appreciated was their professionalism. They were so cordial. The professionalism told me I chose the right company. From the sales call with Paul to the install of my new furnace, I’m extremely pleased. I will continue to do business with them and recommend their service."

"One Hour Heating always does a great job. They’re proactive, great with providing options, they don’t oversell and their technicians know what they’re doing. I am a member of the annual maintenance plan - great, affordable way to stay on top of my equipment, avoiding costly, unexpected expense. Piyush Rami just completed the winter maintenance service on our furnace - he was super helpful, walked me through the work he did and took the time to answer my questions regarding what’s coming now that my furnace is 13yrs old."

"Gerald was a real lifesaver!! We requested same day service because our furnace stopped working during one of the coldest days of the year. It was a dire emergency!! He very kindly called to let us know when to expect him, and arrived exactly when he told us he would. Gerald immediately put us at ease with his friendly, reassuring manner and we were highly impressed by his professionalism, knowledge and meticulous attention to detail. He quickly diagnosed our problem and explained the science behind each step of the repair process to us while he resolved our furnace issues. Then, once the repair was completed, Gerald thoroughly checked and then rechecked his work to make sure our furnace was heating up our house properly again. He provided us with very valuable safety tips and left the work area around the furnace cleaner than it was before he got here. Thank you so much Gerald for doing a fantastic job!!"

"Our power went out in negative temperatures and Jeff couldn’t have been more knowledgeable! He got everything working quickly and he was a delight to have in our home. 10000% will refer anyone to One Hour Heating and Air Conditioning because of how great Jeff was!!"
