EXCELLENT Based on 149 reviews Posted on Google Farrah LoveTrustindex verifies that the original source of the review is Google. Charles was excellent! Had my capacitor go out at 11pm at night and was desperate for service in this Texas heat, many companies didn’t accommodate late night fixes but I was lucky to land on Modern Air. Will definitely recommend!!Posted on Google Richard DavisTrustindex verifies that the original source of the review is Google. We noticed on waking up on Father’s Day that one of our ACs was out. We called Modern Air and Charles was on our doorstep within the hour. He quickly identified the issue and had our AC up and running again shortly afterwards. Excellent service and such a pleasant person. Wholeheartedly recommend them.Posted on Google James SimTrustindex verifies that the original source of the review is Google.

I have been doing business with Charles at modern air of Katy for several years now and have never been disappointed. I've had to call him late in the evening for a problem and he was here within 30 minutes no questions asked. Excellent company to do business with and Charles is an amazing technician.Posted on Google Sam RossmannTrustindex verifies that the original source of the review is Google. Charles was amazing. We noticed that our AC stopped cooling around 10:30 PM. After a dozen phone calls to other so called 24/7 HVAC contractors, Charles answered and was at our house in an hour. He diagnosed the issue immediately and put a plan in place to replace the broken part. He got our unit back online the next day. I definitely will recommend Charles and his team repair and service.Posted on Google David CostaTrustindex verifies that the original source of the review is Google.
