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.

“Francisco Vargas is hands-down the best HVAC tech I’ve ever had the pleasure of working with. He came out for a follow-up and spent over an hour carefully diagnosing and fixing my AC unit until everything was running perfectly. He didn’t rush, didn’t cut corners—he took his time, explained what was going on, and made sure I was good to go before he left. More than just being professional, Francisco is a genuinely great guy—chill, super friendly, down-to-earth, and kind. The kind of guy you’d grab a beer with after work. I can’t imagine calling anyone else out here after this experience. One Hour is lucky to have him, and you’re lucky if he’s the one who shows up at your door.”

He was able to explain the difference in the products they have and how they work. I highly recommend him. He is the reason we will be using this company. Thank you for a great job!”

So they can get back to their normal lives and come home to comfort. When I’m not working I like to hang out in my man cave and watch comedy shows and movies.
