Century Air diagnosed a bad capacitor and blower assembly in one of our AC units and we are back to having a cool house in over 100 degree weather—what a lifesaver! They are always available to fix any problems we have and are prompt, neat and efficient. I would highly recommend them for any of your wine cellar and HVAC needs.

The company is very easy to get in contact with. The technician, Noah, was amazing. He was professional, he knew what he was doing, made me feel comfortable and explained everything to me when he was finished.
Al La P.
Petros and his crew did a very excellent job! We have used their services before and we are glad to have used their company again this time for our two new AC & heat units. I compared their prices with three other companies and Century Air is way much cheaper. Thank you also to them for my free hat, shirt and tote bag. Will definitely use their company again in the future.
Michael C.
Great experience with Century Air and Petros in replacing our wine cellar cooling system. Petros was on time, very courteous and professional, answered all of our questions, removed the old system and left the area clean and tidy. Highly recommend Century Air for any of your A/C or wine cellar needs.

Signs It Is Time to Replace Your HVAC System

Most AC systems last between 10 and 15 years, but the Las Vegas, NV, climate puts extra strain on equipment. It is worth looking into a replacement if you notice any of the following:

If your system is showing more than one of these signs, replacement is often the smarter investment. Continuing to pour money into an old unit rarely pays off in the lon

Benefits of Upgrading Your HVAC System

Upgrading your AC system is one of the best investments you can make as a Las Vegas, NV homeowner. A new, properly sized unit will cool your home more efficiently, resulting in lower monthly energy bills. In a city where air conditioning runs almost year-round, those savings add up fast.

Modern systems also come with improved humidity control, which matters more than most people realize. Las Vegas, NV, may be a desert, but monsoon season brings periods of elevated humidity that older systems struggle to manage. A new unit handles those swings much more effectively, keeping indoor air comfortable no matter what is happening outside.

Beyond performance, a new system brings peace of mind. You are not waiting for the next breakdown or wondering if your AC will survive another summer. New equipment comes with manufacturer warranties, and when installed correctly, it should provide reliable comfort for years to come. Our team takes the time to size and install every system properly so you get the full benefit of your investment.

Our AC Installation and Replacement Process

We start every job with a thorough assessment of your home, including the size of the space, your existing ductwork, insulation, and how the system has been performing. This step matters because an undersized or oversized unit will never work as well as one that is properly matched to your home.

Once we understand what your home needs, we walk you through your options. We explain the differences in efficiency ratings, features, and pricing in plain language so you can make a decision that fits your situation. There is no pressure, and there are no recommendations that do not make sense for your specific home.

On installation day, our technicians arrive on time, treat your home with respect, and get to work. We handle the removal of your old equipment, the full installation of the new system, and all necessary connections and testing. Before we leave, we make sure everything is running the way it should and take the time to answer any questions you have about your new system.
