“Furnace was not working and he got it diagnosed and presented me with a couple of options with repairing or replacing my current unit. My furnace came with my home and is only about 5 years old so I’m hoping to avoid purchasing a new one as long as possible but he was able to get ny furnace in working condition for the time being. I appreciated his upfront explanation of my options moving forward so I will be using company again for my future repairs or replacement. The part I needed was pretty expensive and though I haven’t price checked I’m sure that price was probably pretty standard with industry pricing. Very professional and did everything in a timely manner.The company overall is very accommodating and quick to be there anytime I have needed them so I plan to stay with them if they continue with the way they conduct their business. I would feel comfortable recommending this company to anybody who has any heating or air conditioning needs. And I would highly recommend Tristen as he seemed to do an excellent job overall.”

“One of our furnaces was not coming on. We received same day service within the hour. A reset to a safety switch was made with no cost to us because of our customer care membership. The technician was informative about the tests and service that he performed.”

“Our heat is out. He came within a couple let of hours of calling. Unfortunately I heater is from 1997 and needed to be replaced. They worked out a payment plan that would work for our budget that also gave us a discount. Better than a credit card interest rate. Our new furnace will be here within 24 hours, including installation.”

“We've been using One Hour Heating & Air Conditioning for 15+ years now and have always been impressed with their service. Their staff is always very professional, down-to-earth, and friendly. Explaining what they're doing, why they're doing it, and can walk you through any potential issues, providing their personal opinion, and a variety of options on how to move forward if a problem does exist. In this particular instance, we had a few failing parts on one of our furnaces. Both were expensive to replace, and we were told that other components may fail in the near future as the furnace was 15+ years old. They offered the option of replacing the entire unit rather than just replacing the two parts, which was only a bit more expensive and seemed like the right move, considering the new unit would be under warranty. In addition to that, we found that our chimney liner (which is where the exhaust runs through, then out of the house) had become disconnected and that the exhaust was just leaking into the brick chimney and not exiting the house properly. They told me that they might have to install a new liner, which was an additional cost, but that the previous one looked good in their opinion, and they thought they might be able to reattach. I thought for sure this would be an added cost, but they were able to utilize the existing one, and did not charge me for parts and labor of installing a new one. I believe a less trustworthy company might have installed a new one anyway in able to charge more and increase their margin. I truly feel like they have our best interests in mind, as I've always found them to be trustworthy, as they are never trying to oversell or overcharge, in my opinion. Kirby Alaimo and the rest of the crew that did the install were incredibly friendly and helpful! I would recommend this company/service to anyone! Very happy with their continued service. -B”

“One Hour has serviced our HVAC system for a number of years and our experience with the company has been excellent. Each of the many technicians has been professional, knowledgable, respectful, and always clearly explains everything thoroughly. We also recently had our old HVAC system replaced by One Hour and can’t say enough of how well it went. Tristen was superb and walked us through various options, asking good questions to help justify our decisions on the right components for our needs, and without any pressure. Kirby led the team on the installation. He was fantastic, kept us well informed of everything from beginning to end, and made sure to engage us on any decisions or questions. The new system works great and even has a few extra features that make it easy to use and ensures our comfort all day, every day. We couldn’t be more pleased with the end result!”
