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.

“From Carlos the sales person to Chris the installer, great experience. I had a very small space for them to work and replace an almost 30 year old unit. The sales person came out on Monday and he and the installation manager worked hard to get me what I needed on the next day. I couldn't be more thrilled. Chris was great and straight forward. He knew what he could and could not do and let me know how everything was going through out the day. I had never used One Hour before and when you're spending any amount of money you want to be sure things are done properly. I've had my unit in for a week and didn't realize how hot it was in my home until I could cool it my desire temperature easily.”

“Chris was very polite, professional and a great communicator. Every area he worked or passed through was spotless! He worked quietly and efficiently but took time to answer questions. He gave the best ever explanation of the benefits of duct cleaning and sealant. We absolutely knew we had issues, but his explanation of the likely improvement was very understandable. The Mrs and I will discuss this weekend. I’d be thrilled to have him back and would recommend him to others!”

“Robert was my first technician that discovered the issue with our unit . The wires had burnt and needed to have replaced. Robert was honest and upfront with us and referred Mo to us to discuss all options of a new unit. Mo also was honest and upfront with us as well as very detailed. Mo gave us a great deal and answered all our questions. Very pleased with doing business with them and One Hour company..thank you”

Hard working also went over the install befit they started. Cleans everywhere they worked. And finished as promised. Just and outstanding job all around. Extremely satisfied. Thanks to all.”
