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.

“Mary Stapp did an excellent job in our HVAC yearly maintenance!!! We have been a long time customer of One Hour Heating & Air Conditioning and Mary is by far, the best technician we have ever had. I normally watched how the technicians service our unit and when I came out while she was cleaning our condenser, she was the only one who had taken our condenser apart and cleaned the inside of our unit along with the coil. She was very thorough and did not rush doing her job, took pictures before and after, and very personable and professional. I felt extremely comfortable with her and felt that she is a very honest lady. Unlike other technicians, there was no hard sale of anything. She did her job, showed me pictures of what she had done and explained everything to me. If you are in the lookout for an HVAC person/technician, I would highly recommend Mary Stapp of One Hour Heating and Air Conditioning. She did a phenomenal job, nothing I have ever seen in the past. I told the company that I would only have Mary Stapp as my maintenance technician going forward. The company should commend Mary Stapp for her fabulous/exceptional service. I hope this review is helpful to anyone looking for an HVAC technician.”
