What our customers say about our service
EXCELLENT Based on 132 reviews Posted 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 Leigh Ann ArnoldTrustindex verifies that the original source of the review is Google. Great and fast servicePosted on Linh TongTrustindex verifies that the original source of the review is Google. It was getting colder in Houston so when I turned on my heater and I started hearing a buzzing sound, I wanted to get it fixed as soon I could. I found Modern Air with Google's help and Charles was able to come out the same day to diagnose the problem and get it repaired quickly. He was professional and knowledgeable and best of all, affordable. I will definitely give him a call back if something breaks again.Posted 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.
