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.

“A1 air conditioning is great ! 3 years ago they replaced our AC system. They are diligent in making sure that it working properly with their annual inspections. David was very informative when doing the inspection. He pointed out a potential issue about a tear in the ductwork leading to the unit . Recently we had our ceiling ducts cleaned out of all the dust . There was a whole trash can full . Now , we breath better and our allergies are much better. Thumbs 👍 up to A1 Air conditioning!”

Donavan Rohde

VP of Operations

An Ohio native that makes Las Vegas home, Donavan has been with One Hour Air Conditioning & Heating^® for over 11 years. After owning a bread distribution company, a friend suggested that he give HVAC a try. Good thing, because since starting as a Maintenance Technician, he’s steadily worked his way into his role as VP. Along the way he’s been instrumental in helping the Las Vegas One Hour Air Conditioning and Heating^® franchise win the President’s Club Award three times, and an NPS award during the 2017 brand convention.

He’s worked hard – advice he passes along to anyone interested in the industry is that “you get out of your profession what you put into it” – but also keeps the atmosphere in the office light and fun. And when he’s not at his day job, he takes advantage of all that Mother Nature has to offer by golfing, hiking, biking and snowboarding with his sons.
Chad Valdriz

Operations Manager

You might occasionally hear Chad greet you with an “aloha,” since he was born in Hawaii. Of course, today he lives in Las Vegas with his wife and three children. A 21-year veteran of the HVAC industry, Chad has been with One Hour Air Conditioning & Heating^® for 11 years. Chad is a problem solver and loves a challenge, which helps him work through any HVAC solution and inspire development of the other technicians he works with. His career has been a personally and professionally satisfying experience, which he credits to the support he gets both locally and from the One Hour corporate office.

When he’s not helping out customers, Chad spends time with his family, sharing special occasions with his wife, supporting his kids in sports and school activities, and even finds time to squeeze in a round of golf when possible.
