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.

“The Tech (Seth Story) that was sent to my home was very professional and informative. He didn't mind me following him around, asking questions. He was honest in his recommendations and was completely up front. This was very refreshing. He even got up into the attic to assure that his assessment was completely accurate. I would definitely recommend One Hour Air to anyone needing ac service!”

“Sean did an awesome job He was out the day after we first called to inspect the system, found a leak & called to make sure we got the best price for warrantied parts. It took 3 weeks for Lennox to ship the part but Sean was out the day after it arrived to install it. He was prompt & courteous and even put up with us kennelling our dogs in and off throughout the installation. Great guy. Highly recommend.”

“Trevor was the tech who came to look at my A/C and recommended for me to replace unit. I was out of state at the time and Trevor took the time to FaceTime me and show me the problems and explained everything in detail. We actually stayed on FaceTime over an hour to talk about every detail! Everything Trevor promised during the installation he delivered! New A/C was installed 2 days later on a Sunday. He also offered a portable while I waited for the installation. Upon arrival of installation it was Logan, who also was very pleasant and took time to show me everything I needed to know. He also took the time to show me the new thermostat and made sure I knew how to set everything up before he left. The entire process was made easy and everyone made sure to explain everything.My overall experience was beyond expectations 10/10. I HIGHLY recommend one hour air!! CALL THEM!! You WILL be happy! Big thanks to Trevor and Logan 🫶🏻”

“I have to say that Sean was the best customer service I have ever experienced. Incredibly knowledgeable, spot on and was looking out for my best interest. I would give him 10 stars if I could. They responded on time the day I called them. I am going to upgrade my system for mom. Thank you so much. Don’t waist your time with the other company’s around. These people are top. Just posted the review. Thank you sir. That's the best customer service I have ever received. God bless and enjoy the eggs. I hope you will come back. Well another crew came the next day to do the installation. What a crew. Joe and his supervisor were on it. The job was completed right the 1st time, looks great, works great. Square, level, caulked, new insulation and registers, thermostat new, wiring new, breakers new, condensate drain new. I a really happy with the work and the unit. Again, absolutely the best. Thank you.”

“Had an A/C emergency around 6PM when the house started heating up into the high 70s. Called One Hour Air Conditioning and Heating in Gulf Breeze, and Jimmy Thomas showed up within about 15 minutes. Super friendly, professional, and clearly knew what he was doing. He had the system up and running again in under an hour. Outstanding service—fast, efficient, and reliable. Definitely will do business with them again!”
