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 technician will walk you through all costs using our Straightforward Pricing 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 worked to build 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.

What is HVAC?

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.

“Just prior to listing our home for sale, our heat pump died. We contacted One Hour Heating and Air Conditioning, and they sent a technician that day. He was professional and knowledgeable. We could repair it or replace it. Given its age, we replaced it, and the installation was done in a few days. Tremendous service! Fast forward to our new home. We opted to replace both 21-year-old HVAC systems (upstairs and downstairs) and there was no doubt which company to call, One Hour Heating and Air Conditioning. The contracting process was simple and easy, and the price was very reasonable. The team of technicians, led by Ludwig, were on-time, professional, and did a great job and they thoroughly cleaned up when they finished, which was nice. After two transactions in 6 months, with both installations having gone smoothly, I can’t say enough and highly recommend them.”

“I don’t usually leave reviews, but this guy was different. He showed up on time, super friendly, and you could tell right away he knew what he was doing. Didn’t waste time guessing — found the issue with my A/C fast, explained it in a way I actually understood, and gave me a few solid options without pushing anything. What stood out the most was how easy he was to talk to. No sales pitch, no pressure — just honest advice and real help. That kind of service is hard to come by these days. If you need someone who actually gives a damn and knows what they’re doing, this is your guy. I’d recommend him in a heartbeat.”

“I would like to share a truly wonderful experience I had with a technician who came to service our air conditioning. His name is Seth, and he made such a positive impact on us during his visit. He was not only professional but also incredibly friendly and knowledgeable. His excellent people skills really stood out, and he made us feel comfortable throughout the entire process. Thanks to the outstanding service we received from Seth, we felt assured that we were in good hands with the company, so we decided to sign up for the VIP program. We want to extend our heartfelt appreciation to Seth for his exceptional work. We hope others will recognize his efforts as well. Warm regards, The Del Rio Family Bonita, California”

“I was just about to give this place a one star because of how incredibly lazy Jose was. The guy was in and out in 30 minutes. He didn’t do any of the things I had originally asked him to do. Company made it right and sent Anthony! This guy came in with a great attitude and was very informative. He stayed 3 hours fixing what Jose failed to do! We decided to enter into a yearly plan with this company not only because of his effort and attitude, but also because of his knowledge! I highly recommend calling and asking for Anthony! Thank you so much for your help Anthony!”

“David the lead installer and his helper Chance did an excellent job with the installation of our new AC unit! They came back to resize our air intake as it was making an awful noise when the AC turned on. We are so happy with the results! When the AC turned on before it sounded like a jet engine, now you can barely hear it! They were very courteous and professional! Thank you One Hour Air Conditioning and Heating and thank you David and Chance!”
