Henry is amazing. He has worked on our church's A/C units (46) for 5 years. He takes his time to do a proper diagnosis, then systematically eliminates the problems therefore only fixing what is absolutely necessary. He has saved us so much money over the years because of his attention to details. Instead of just "blanket" replacement of parts, he'll work to find the exact issue and save you money. Uses the latest technology and has a deep experiential base to pull from. Can work on larger 7.5-10 ton units. Highly recommended!
