EXCELLENT Based on 142 reviews Posted on Matthew FloresTrustindex verifies that the original source of the review is Google. Awesome response time. Fair price and no surprises. Modern Air is my official HVAC company!Posted on Ron SelvageTrustindex verifies that the original source of the review is Google. Had a problem with my AC where it would only blow out hot air. Ot was Sunday, so I made an appointment for Monday afternoon online with Modern Air of Katie. Monday morning came around and a morning meeting I had was canceled. I called Modern Air and they were about to move up my appointment right away. Charles showed up on time and he diagnosed the problem, gave me a quote, and then replaced a part it in about 15 minutes. Very quick and at a reasonable price. I was very happy with their service and would definitely use them again.Posted on Jesse RobertsTrustindex verifies that the original source of the review is Google. Had a great experience with Charles. He took care of my AC issues and was easy to work with. Would recommend.Posted on Jeena RobertsTrustindex verifies that the original source of the review is Google. I called in a panic at 1am and the tech was at my house within 30 minutes of my call to Diagnose and repair. Was efficient and thorough. Did not try to upsell any part or cost. Technician Went out of his way to find a replacement part under warranty so I paid no cost on the 2500$ part. He uninstalled my Blower motor prior to leaving, got the new replacement at 8am when they opened and had it Installed and my AC working by 10am. My only charge was labor. Highly recommend. Prompt. On time. Efficient. Knowledgeable. Cost effective. 24 hour emergency repair with no Added cost for a 1am service call. Came out as soon as he got My call. Five stars!!Posted on Bary BrooksTrustindex verifies that the original source of the review is Google. I highly recommend Charles at Modern Air of Katy for his exceptional service and expertise. I recently encountered an urgent AC issue just 24 hours before a new tenant was scheduled to move in. Charles arrived promptly, conducted a thorough diagnostic, and had the system functioning perfectly in short order. His efficiency and attention to detail during such a high-pressure situation were impressive. It is rare to find this level of professionalism and customer care, and I will certainly be relying on his services for all my future HVAC needsPosted on Catha JaynesTrustindex verifies that the original source of the review is Google.

Exceptional service. We made an appointment; he called when he was on his way and arrived in a timely manner (Copperfield). Very knowledgeable and professional. He walked me through the details, explained what was going on and made repairs. I would highly recommend for anyone needing their systems checked out or repaired. Also, I will be switching my heating and air conditioning annual maintenance to them. With that, I want to add of all the companies I have used over the years Modern Air of Katy has been the best.Posted on Temi LTrustindex verifies that the original source of the review is Google. Charles assisted us with an ac inspection on our new house. We recently had some issues with the ac due to critters getting to the wires and he was able to come out timely and helped us fix it at a reasonable price! He’s very personable, works within your budget while giving great advice. We’re very happy to have found him and will use him for all our ac needs. Thank you, Charles!
