“One Hour Review My wife and I after 22 years decided it’s time to replace our A/C Furnace system. We did our homework and this is what we found. Without going into models of system, it was very important to have a company who would stand behind the product they sell. Our first search led us to a big box store. We knew they would be behind the company they subcontract to. The sales person who came to our home was very nice. He set us up with a couple good systems to choose from. He also offered us a few thousand in cash back incentives to be spent at the big box store. It was very tempting. The next company we contacted was One Hour. KC was and still is our salesman/point person who went out of his way to meet our needs with a system appropriate to the square footage of our home. He made sure at any time we were his primary focus. The pricing was slightly more for the three systems he had shown us. The one we choose, I can say is the best system I have ever experienced. Quiet, efficient and quality! No silly business. No free credit card to spend at the big box store. The money we invested was all for the unit One Hour provided. We are extremely happy with the entire team. You almost feel like you become part of the One Hour family. A family commitment. From Jane our contact person who answered every question and kept communication strong, to Rami and Jessi our technicians who completed the installation…..completely professional. The entire team! Thank you KC! Thank You One Hour / Service First Mentality!! I’m posting a couple photos.”

“KC was awesome today. He went above and beyond explained to me what we need to replace the old system including the indoor air quality products, the price compared to the other installer is a lot less. Thank you KC”

“Got a new AC unit installed for a good price. Krunal was thorough with initial appointment, gave an estimate and also offered quick installation. Within 3 days I had my AC unit replaced and running. The installation crew were professional as well.”

“I highly recommend these guys. Not only did they do an amazing job, they went above and beyond. They walked in as strangers that never felt like strangers. I felt like I had some friends coming over to put in an air conditioner unit for me. If I could go more than 5 stars I would have… I give them 10 stars. So nice from the first phone call to the end of taking out the trash…”

“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”
