“I had a problem with my water heater earlier this year. It was very frustrating, I called Naperville One Hour Heater. Krunal came over and educated me on my options. He also educated me about my home air quality. I never heard about air quality even though I had a quarterly service but never mentioned anything about that. We agreed on a job that fits my needs and budget. His team replaced the water heater and they did great job, it was neat and clean. They cleaned my duct, and placed an amazing filter and a Led to purify my hole air quality. I am very happy with their service and I have a membership with them to make sure our air quality stays the same. Definitely consult with them”

“My wife and I were very pleased with the service from beginning to end with One Hour Heating and Air Conditioning of Naperville. They were responsive to our needs in helping us to select a new AC and Coil system and were reasonably priced. Highly recommend.”

“Had an old unit which wasn’t working up to standards. Kept shutting off. The folks at One Hour Air came out gave me a very fair price and replaced the unit. From my first communication with with them to the installation everything went smooth and professional. I also used their duct cleaning which made the air inside my house free of contaminants. Great all around!”

“Best servicecompany in the area. We called them about 30 minutes before they show up at our door steps. Great education presentation by KC and Zo. I highly recommend them if you are looking to improve the indoor air quality, comfort and efficiency of your new or existing system. These guys takes time to educate you and your need.”
