What 142+ clients say about One Hour Heating & Air Conditioning of Naperville

I couldn’t be happier with my new furnace installation. After my old unit failed in middle of winter. I called multiple companies to give a quote, one company pressured us so much we were very put off the by whole process. I called One hour and Krunal, the manager, came that night to assess the situation. He provided us with a fair and transparent quote without feeling like we were being pressured. Krunal and the technicians arrived the next day with a new furnace and were incredibly professional. We also decided to get the oxyquantum LED and electronic air filter. The difference in my home's comfort and air quality was noticeable within the hour. If you are looking for reliable and personable HVAC service, I highly recommend this team for their expertise and exceptional customer service!

“One Hour Review My wife and I after 22 years decided it’s time to replace our A/C Furnace system.”

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.

“I highly recommend these guys.”

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…

“Had an old unit which wasn’t working up to standards.”

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!

I've had my share of bad experiences with previous HVAC vendors who are typically unprofessional, just looking for a sale, or untimely. However, One Hour Heating & Air Conditioning changed that for me. They are always on time, provide me with unbiased recommendations, and really show their care for customer relationships. I've used them for my all-home humidifier replacement, as well as duct cleaning and UV light system installation. Great value and professionalism, which is difficult to find these days. Za and Krunal especially are always a pleasure to interact with.

“My HVAC system died at my yoga studio on a night it was below zero.”

My HVAC system died at my yoga studio on a night it was below zero. it was well after 8 PM and I immediately went onto Thumbtack in a state of panic knowing i had early classes the next morning. KC from one hour responded immediately to my request and he was very helpful and reassuring. By the next morning he had a technician out to my studio and it was fixed by that afternoon. Rami the technician worked very fast and diligently. My unit is on the roof and he was up there in freezing temperatures! I highly recommend them for commercial HVAC situations! KC even came to my studio to explain exactly what parts were needed and helped me understand the pricing. you should definitely use them just be patient with their customer service people 🥴
