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 SEER2 Rating?

The SEER2 (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER2 rating, the more efficiently a unit operates. The SEER2 rating of any given unit can range anywhere from 13 to 21.

“Brad Gong did an exceptional job of getting my AC going again in less than 10 minutes and took care of the entire appointment in 30 minutes. He managed to make it to my place on very short notice and provided a prompt, competent, and comprehensive solution to the issue I was having in the middle of the summer in the midst of extremely hot and humid days. He is clearly highly knowledgeable, clever, and proactive in the manner that he addresses challenges. Also, he exemplified tremendous customer service in the form of clear communication, honesty, and impeccable character. As a result of the trust and goodwill that he naturally and sincerely provided on this service visit, I will make an effort to request him in the future due to the expertise and all of the wonderful qualities that he infuses into a difficult situation.”

“Romaney was fantastic. After determining that the problem was located in the compressor, it didn't take him long to pinpoint the problem as a leak caused by something the factory did when they installed the coil in the cabinet of the compressor. He was very thorough in his answers to my questions, and look forward to his or another technicians return visit with the new coil next week.”

“Needed an AC check during the 90+ heat wave. Jesus was excellent at completing the job in a timely manner, communicating throughout the entire job and acting professionally. I especially appreciate him going above and beyond by staying a little longer after the repair to make sure my house was getting cooler and nothing else was needed. The repair was affordable and I will definitely use this company again based on the service he provided.”

“Bob was very helpful with explaining my options and coordinating the installation for the day after I decided. Brandon and his coworker were very professional and did an excellent job with the installation. I was very pleased with One Hour Heating and Air Conditioning and highly recommend them.”
