BEWARE! This is a predatory contractor. Funny how all of their good reviews were posted at the same time. They prey on elderly and unknowing homeowners with scare tactics and false information. They will tell you they have to "restore" or "rejuvenate" your system which is just a glorified cleaning for $1000.00 or more. Then they tell you they will discount that money off a replacement system if their fake method doesn't work, which makes you stuck with using them. Since they don't do much during their service, replacement will soon follow. Total bait and switch. They actually made my situation worse until I called someone else to fix it. I got an installation estimate from them on my system they didn't fix and they were $1200.00 more than the closest company and $3000.00 higher than the lowest. This company will victimize you!
