From the first phone call to the final walkthrough, everything was professional, honest, and stress-free. They showed up on time, explained every step, gave a fair price, and left the work area spotless. The quality of the installation was outstanding, and you can tell they take pride in doing the job right—not just getting it done. If you're tired of unreliable contractors, this is the company to call. Excellent customer service, top-quality workmanship, and people who truly care. I wouldn't hesitate to recommend them to anyone who needs heating or air conditioning work.
One Hour Heating & Air Conditioning is a great and reliable company. The staff is very professional, and the job was completed promptly and efficiently. They provided excellent service, and I was very pleased with the entire experience. I highly recommend them to anyone in need of heating and air conditioning services. Vili and Kris Mirtchev
This company is amazing!! I called yesterday (day before Mother’s Day) because I had a clogged sink and was literally about to loose my shit. They were so helpful and got me an appointment next day (on Mother’s Day) where I didn’t have to stop my day because they send you a link where you can track their eta. Ralph was so knowledgeable and informative he took his time to help us understand the issue. The pricing was great, these guys aren’t looking out to get you! Hire them!!
One Hour was very responsive. I booked an appointment at 8AM, Scott called by 10 to say he was in the area, I explained I need to be out by 12 and he got here by 11. He was very knowledgeable and professional and was able to diagnose the problem. I highly recommend them.
Fast and very professional service. Explained what would be better for us and an estimate. The day of replacing the furnace they were on time and other men showed up with Mark. When we saw the crew we knew they would be able to get it done fast. Great job.
