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.

“Mark with One Hour Heating and Air Conditioning was awesome! He showed up on time, was extremely professional during the service call, did a thorough inspection of our entire system inside and out, and provided very reasonable recommendations for additional preventative maintenance of our system. I will definitely be scheduling again. Thanks Mark!”

“It is truly a pleasure to write this review and thank Mark Medina for the outstanding service he provided on our air conditioning unit. Mark was prompt, efficient, highly professional, and respectful—even taking the time to put on booties before entering our home. He is one of the most honest, personable, courteous, and knowledgeable service technicians I’ve ever had the privilege of working with. Mark is extremely trustworthy, and his service was nothing short of exceptional. He took the time to explain his diagnosis in clear, layman’s terms. No one ever wants to hear, “You need a new air conditioning unit,” but Mark managed to soften the blow with his fairness, expertise, and uncommon empathy for our concerns. Fortunately, in our case, all that was needed was a little cleaning—and we were good to go! He personally showed me what he was doing and explained each step along the way. The entire experience was made as painless as possible. A true 5-star experience—I’m a grateful customer and happy to highly recommend Mark and One Hour Heating & Air Conditioning for all your heating and cooling needs. A big shout-out as well to the owner and founder, and to the company’s “Heroes Club” supporting our military and all first responders. One Hour Heating & Air Conditioning — We thank you for “your” service!”
