EXCELLENT Based on 133 reviews 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!Posted on Shaun WymesTrustindex verifies that the original source of the review is Google. Great service - decent pricePosted on Zach FrederickTrustindex verifies that the original source of the review is Google. Great service, Charles is extremely knowledgeable and professional.Posted on Trey PerdueTrustindex verifies that the original source of the review is Google. We had a very positive experience with Modern Air of Katy. Their technician was thorough, professional, and took the time to explain what was actually happening with our HVAC system instead of defaulting to a full replacement or unnecessary repairs. They identified airflow and static pressure issues that had been limiting performance—items that often get overlooked but make a significant difference in comfort and efficiency. After the adjustments and cleaning, the system is running noticeably better and more evenly throughout the home. What stood out most was their honesty. They focused on optimizing what we already had rather than upselling, and the work felt thoughtful and well-executed. Communication was clear, the visit was efficient, and the outcome matched what was explained. We would absolutely use them again and recommend them to anyone looking for a knowledgeable, no-pressure HVAC companyPosted on Richardson PhamTrustindex verifies that the original source of the review is Google. I am so glad we found Mr. Charles. He is very well experienced (20+ years), fast, efficient and honest. We did not sense that he was trying to add extra services for more money. He was reasonably priced and recommended what we needed to get fixed. We have noticed our AC not working the day I had just brought home our newborn baby. Thankfully he was able to come the same day and refilled the freon. He addressed that we actually had a leak, and would need a full replacement so the freon was temporary but it was enough to keep us cooled in the mean time. He credited the freeon replacement towards the AC replacement once we agreed to move forward with the replacement and got right to work! We are very happy and highly recommend Mr. Charles for your services.Posted on matt simonelliTrustindex verifies that the original source of the review is Google. Came over same day to assess my issues same day, and got my system fixedPosted on Sharon AndersonTrustindex verifies that the original source of the review is Google. Great Service. Very professionalPosted on jacqueline ruffinTrustindex verifies that the original source of the review is Google. Charles came to my home and fixed my AC compressor after a night of heat and humidity. Took him closer to 1 hour to get us squared away. Quick response time to my messages and friendly service. Definitely would recommend him and his company.
