These guys did an outstanding job replacing our central A/C unit and also did some new duct work for us, and retiring the ancient decrepit swamp cooler unit. They did a great job making the new install look a lot cleaner on the roof, disposing of the condenser water properly, and we're keeping the house cooler while using less power. They even set the fake owl that had been knocked over in a wind storm last year back up. Oh, and they came in about 100 bucks below their quote even after a thermostat upgrade. The installers were friendly, professional and went out of their way to make sure we understood the finer points of our new system. I understand they provide financing, but I paid cash so I don't know what sort of deal you get with that.
I don't think I'm ever going to let anyone else touch our HVAC system again. I'm calling my home warranty company to recommend JMAC as a provider. They are simply the best.
