Do you service emergencies after-hours?

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.

“Roy came over and went straight to business. He was very professional and friendly. The first interaction he was patient with me explaining the moving parts of my AC, didn’t push for me to simply buy an expensive part or a whole new unit as it was a simple fix he had done. When he came back to check up on my unit he complemented on how clean it was, as I made sure to take his advice on maintenance seriously. I highly recommend One Hour. They really care about their business and know with the Florida heat we, the customers, really appreciate having a working AC!”

“After having a problem a year ago with my split air conditioner, One Hour Air Conditioning & Heat Company came out & fixed it. I also was greatly relieved to be able to joined a wonderful program they have, where they come out twice a year to clean and make sure everything is working. I was scheduled for my second appointment, on the day I picked, that was convenient for me, they sent their employee name “ Junior.” He knocked on my door with the warm smile, said hello & explain what he would be doing on the outside & inside inspecting, making sure it was clean & in top shape condition. I am not the greatest in always understanding all the instructions, that comes with the air conditioner, Jr was so wonderful!! When I asked if he could help me, he took time to explain and even show me some things on my remote control & truly just helped me. He did all this with such patients, friendly, kindness, even if he had to explain it to me twice. I was so grateful to know that this wonderful company has such great employees. Truly from the person answering the phone to the representative that comes out, my experience has been nothing but happily kind, reassuring, efficient results. I truly recommend this company whole heartedly & who knows you may also just be lucky enough to have this wonderful man named Junior knock on your door, greeting you with his wonderful, kind, smile❣️ Ollie R🌺”

“My air conditioner wasn’t working properly, I called one hour air conditioning for same day service. They showed up on time and they were very professional. The technician Angel Guardado did all the tests needed and found out we needed refrigerant. I’m super satisfied with their service.”
