Mission Success & Reviews

2015 Build, 2500 sq ft home. The builder installed a 13 seer 3.5 Ton Lenox HVAC system. The system worked but struggled for 9 years. Contacted a few AC people and Trilogy AC had a better price for a Carrier 16 seer 5 ton system. Install took 7 hours. They were very professional, very careful of the yard and house. They cleaned everything up. New system was installed even better then the builder. Everything is perfectly leveled and secured properly. Sealing the areas around the furnace looked like art work. It was not slapped on and left. Very clean install! Definitely recommend Trilogy AC.

I can’t say enough great things about my experience with Trilogy AC company and Nasser Mattar! Their service is absolutely top-notch—fast, reliable, and always done right the first time. Whether it’s a quick fix or a full system install, they always deliver with professionalism and expertise. What really sets them apart is their amazing customer service. From the moment you call, you’re treated with kindness and respect. They truly care about their customers and go above and beyond to make sure you’re comfortable and happy. I highly recommend this company to anyone looking for honest, dependable, and skilled AC services. You won’t be disappointed!
