What thermostat setting makes sense during a Las Vegas summer?

Many homeowners set their thermostat around 78 degrees when they are home during the summer, then raise it a few degrees when they are away. In Las Vegas, where AC systems often run for long stretches, a programmable or smart thermostat can help balance comfort, energy use, and cooling performance without constant manual adjustments.

What should I do if my AC fails during a Las Vegas heat wave?

If your AC stops working during extreme heat, check the thermostat, circuit breaker, and air filter first. If the system still will not cool, schedule emergency HVAC service as soon as possible. A technician can inspect the system, explain the repair options, and help restore cooling before the problem gets worse.

How can I improve indoor air quality in a dusty desert climate?

Start by changing HVAC filters regularly, scheduling routine maintenance, and keeping vents and returns clear. If your home still feels dusty or stale, indoor air quality services such as duct cleaning, improved filtration, air purifiers, or humidity control may help reduce particles moving through the system.

How often should my HVAC system be serviced?

Most homes benefit from HVAC service twice a year: once in the spring for the cooling system and once in the fall for the heating system. Seasonal service helps prepare your equipment before heavy use, catch smaller issues early, and keep your system running more efficiently.

Is weak airflow usually an AC problem or a ductwork problem?

Weak airflow can come from several issues, including a dirty filter, blower problem, blocked vent, leaking ductwork, or restricted airflow inside the system. A technician can inspect both the HVAC equipment and ductwork to determine whether the problem is with the AC, ducts, thermostat, or another part of the system.

When are HVAC financing options helpful?

Financing can be helpful when your home needs a larger HVAC repair, system replacement, or comfort upgrade that you would rather not pay for all at once. If your system fails unexpectedly or you need to replace aging equipment, financing options may make it easier to restore comfort sooner.

How do I know if my home needs duct cleaning or duct sealing?

Duct cleaning may help if you notice dust around vents, musty odors, debris from registers, or worsening allergy symptoms. Duct sealing may be the better option if your home has uneven temperatures, weak airflow, or high energy bills caused by air leaks. A ductwork inspection can help determine which service is the better fit.

Why do some rooms in my Las Vegas home feel hotter than others?

Uneven temperatures can be caused by duct leaks, poor airflow, blocked vents, insulation issues, thermostat placement, or an HVAC system that is not sized correctly for the home. If certain rooms stay uncomfortable, a technician can inspect the full system and recommend the right fix.

How do I know what size HVAC system my home needs?

The right HVAC system size depends on your home’s square footage, insulation, windows, layout, ductwork, and comfort needs. A professional load calculation helps determine the correct size so the system can heat and cool efficiently. A unit that is too large or too small can lead to short cycling, higher energy bills, and uneven comfort.

Here's how we helped one household during a Las Vegas heat wave:

"We had One Hour Air Conditioning install a new A/C unit last summer. We were in the middle of a heat wave when our old unit stopped working so while we waited for the new unit, One Hour Air Conditioning loaned us portable A/C units and installed the exhaust hoses through the windows so that we were comfortable while waiting. They have come out more than once to check on the unit. Today was the last call they made as part of their free one year check up and maintenance. Very professional and thorough service tech. I would highly recommend their work to any one. We are very happy. They are also very reasonably priced."

We got two bids for a new AC & Furnace and ONE HOUR was most honest and timely. They came the next day and installed everything and then the next day came to clean all the vents by vacuuming out and hand cleaning each vent. The crew were polite and professional. We got new thermostats as well and it came with a 10 yr warranty. So far the systems are running great and we are very pleased. They also used traps all through out the house and cleaned up all the mess and took everything away. Highly recommend ONE HOUR AIR CONDITION & HEATING. Best in this town and they do not try the rip you off. Obviously ‘new AC units and a furnace are expensive but for people not paying cash, I am sure they have good financing available.

One Hour provided excellent service as usual and that is the reason we have been with them for 35+ years. James has been thorough with every visit. After his recommendation, we elected to have One Hour install a new A/C and heater combination less than 24 hours after making the decision Albert and his crew moved swiftly and professionally and I was extremely pleased with the work and the products that were installed. One Hour and staff A+.

I sought and received a second opinion on my AC issues and I received timely, efficient service. The tech's name is Daniel Laymon. I thought I was going to have to wait hours, but he came out within 30 minutes of my call. Daniel inspected the system thoroughly and gave me all of the information and options I needed once I'm ready to go forward.

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 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.
