The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.
It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.
Your filter should be changed every one to three months, depending on conditions in your home and your region’s climate.
We work built relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.
Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.
HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter.

In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house.

Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.
The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.

“By far, the best company we've dealt with in 35 years. Timely and affordable. Charles and Michael did a fantastic job!”

Peggy Rapp

“After waiting all day for a scheduled air duct cleaning from another company ,& unreturned calls .. I reached out to One Hour Heating & Air conditioning. From the first contact, Craig was helpful & personable! He expedited my service & they arrived as promised! Michael & Charles were timely & polite. They went out of their way to explain everything they were doing &beyond mannerly & knowledgeable. It was a great gift that the other company never responded! I plan future work with One hour & I recommend them to anyone looking for dryer vent cleaning to Heating & Air. I am grateful to have found this company!”

Kate Myers

“I had asked for a recommendation on our local community neighborhood website for someone to service a gas fireplace. Several of the responses were for the same person, who came highly recommended. I made arrangements for that person to come out. He said he was busy but could come out the following week. No problem - we could wait a week. In the meantime, Craig from One Hour Heating sent me a message in response to my posting. I didn't respond at first, because I thought we were all set. A week goes by and we hear nothing from that other person. I text him and he says he was super busy and he would have to come out the following week. Seeing as how he didn't proactively reach out to me to say he couldn't come and that I had to contact him instead, plus the new delay, I contacted Craig. Craig was very responsive and set up the appointment for the next business day. Not one, but three service technicians showed up - on time!. They were very courteous and friendly. I showed them what needed to be done - replace a gas valve which I had already purchased - and they got right to work. It took about 90 minutes and the job was completed with no issues. The fireplace is now running again and looks great. Interestingly, just before I started writing this review, the "other guy" texted me and said he couldn't come by yesterday (Thursday) because he got busy, but he could come out later today (Friday). Well, he never even made arrangements to come yesterday. By texting today, he was giving me an hour or two notice. Not a good method of communicating with customers or scheduling. One Hour Heating communicated perfectly and followed up after the job to make sure I was all set. While they were at the house, the three technicians said they would come back if there were any problems. Good way to win customers! Craig gave me a price ahead of time and that's what the final bill was - exactly what he quoted! And the price was fair. I would definitely recommend them and use them in the future. Thanks to Craig and his team.”

Fran Hart

“My home HVAC system quite working and was without heat. They responded to my call in a couple hours. After checking out my system they came back and replaced my compressor and blower fan and some electrical components. Technician was very professional and had my system back up in no time.”

Mike Ingham

“Craig and his team were incredibly responsive and persistent in fixing a complicated issue. They did this while helping me minimize cost. Can’t recommend enough!”
