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.

“First and foremost, I must commend our technician, Ronnie. He was on time, communicated with me about his arrival time, and clearly was very knowledgeable and efficient. So why not 5 stars? When my unit stopped working, I first suspected a bad capacitor, as this had happened once in the past. I checked the local stores, the capacitor would have been about $35, and replacing it is a 10 minute job. Unfortunately, none of the local stores had the size I needed. It was 90 degrees outside and we didn't want to wait for an online purchase to arrive, so I called One Hour. Ronnie confirmed that the capacitor, but I was more than a little shocked that it cost $354 installed. Further testing revealed that I had a leak in my evaporation coil and it needed to be replaced. Long story short, after $4,000, the A/C is working great and we are happy, but considering the cost of the capacitor replacement, I question how much more I overpaid for the refrigerant (R410A). I paid $1,060 for 8 pounds.”

“Austan was outstanding. Answered all of our questions thoroughly AND showed us a number of features about our unit and explained why it was doing what it did. We love good information! While he was here, he brought up the importance of a surge protector, why we needed one, and how it works. That was a great tip, so we got one, and he had it installed in no time flat! Great tech, really nice guy, great service call!”

“Called One Hour Air and they were able to be at my home same day. Nick E. was our technician. He was very polite, professional, and walked me through every step of his inspection and repair. He finished repairs same day and the quality of the work was outstanding. Nick was very knowledgeable and gave great recommendations on how to keep our AC running smooth and efficiently all year. All around it was a great experience and I would highly recommend. Thank you, Nick and One Hour Air!”

“Austin came over and diagnosed my air conditioning issues less than 10 minutes being here. He's very thorough and experienced as well as very respectful of client's needs! I signed up as a member so they can continue to take care of the a/c unit. GREAT JOB AUSTAN.”
