Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

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.

How often should I service my HVAC system?

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.

How often do I need to change my HVAC filter?

Your filter should be changed every one to three months, depending on conditions in your home and your region's climate.

Do you offer purchase financing?

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.

What are the advantages of a smart Thermostat?

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.

What is a SEER Rating?

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.

“He ts the problem and unit required replacement. He talked to us and got our info to set us up credit and finance . ×××××××××××÷÷÷÷÷××××××××××××××××× Trice did come out second time after several failed attempts to get financing. We secured financing thru a different company and he came out and completed contract and setup time for install for system. He was very professional and complete in all his answers. He was on time and we got it done quickly. We were able to schedule for next day for removal and install of new system. Would definitely recommend company to friends and use them again. Xxxxxxxxxxcxxxxxxxxxxxxxxxxxxxxxxxxx The guys that did the the replacement dud a great job. They were about 25 minutes late getting here but said the distributor was late. They didn't waste any time and started right in on the task. I showed then we're everything was and got out of the way. They kept at it for approx 4 hours and got the whole job done. They were very quick and polite when using our stairs and doors. They put my things back in order when they were done in the backyard. System was running and thermostat instructions were given to us upon completion. Overall great experience and company. Would use again and recommend to friends.”

“Jacqueline and Adam came over and showed me a lot of the deficiencies. On my ductwork that I did the whole house there was a lot of places the tape was not missing and also the air conditioning unit heater was completely off, but no duct tape. Adam Jacqueline was so nice that they taped everywhere. I need to tape that Hometown didn’t do that was supposed to do they did it for free. I definitely will use them from now on until I sell this house. I’m very disappointed with Hometown heating and air plus the person that came over was not a nice person at all Jeffrey did the estimate . I will not use them again ever.”

“Gary answered his phone on the weekend and showed up to diagnose my issue. He was there within 1 hour and gave me an estimate the next morning. The quote was fare so he sent his help over and got us done quickly. We are very happy with our new A/C as well as our renters....”

“Initially I was super angry because Mr sparky broke my air conditioner after doing an electrical fix for some wires. I had been waiting over 8 hours for this company to fix my unit and I was hot and aggravated!! Called so many times for updates I’m sure they were sick of me. But let me tell you when John got here he showed genuine concern for my problem. Asked me to explain my situation and i quickly remembered it wasn’t his fault or this companies fault. He was kind professional and fixed my unit so fast. To go into something angry and come out complete opposite was a happy surprise! Thank you all!!!”

“Very satisfied with this company - we have been on their monthly service plan for a couple of years now and it has been very worthwhile keeping our ac/furnace/water heater all maintained and running at peak efficiency! We have also been very impressed with the various service techs we have had on the property (Brody was just here today) - they have all been very nice, knowledgeable and very thorough in explaining what they diagnosed and what their recommendations were. Glad we chose to deal with One Hour and happy they are taking care of our home!”

My technician were nice, got the job done and cleaned up with no extra cleaning left for me to do. Looks like they weren't even here have it not for the cool air circulating in my house.Thank you.”
