Tom checked over everything and flushed lines with shop vac and poured a commercial chemical down and got the system up and running in no time.

One time "John" answered and I told him I was interested in an HVAC maintenance and service contract. He rattled off some numbers and promised to email them to me that night. Never got anything. I then called that number over and over, leaving messages that again were never returned. Finally, a woman answered and explained that she was in a front office and could give me no info (??) about service contracts, but she said if I called 800-921-0392 an answering service would take a message and forward to someone who would call back. She also promised me that John would send me the promised info that day. Not. So I called the 800 number and left a message for someone to please call me. Nothing. I give up. Too many other HVAC companies that care. I wonder how if they respond to customers needing emergency service.

The kid did a fantastic job but we were charged $2800 for a $17-1800 dollar job. Called in to ask why it was that price when 2 other places we called both said the same price, $1000+ cheaper. Took the manager I guess he was 2 weeks to get back up with us and he said he had to do research on how competitive the pricing was and kept trying to explain there quality of parts and service warranted the cost. Well my wife wouldn't accept it and they finally refunded us $250. So we cancelled the contract and just had another plumbing issue and used Drain Chasers Plumbing in Georgetown and he was fantastic. Super nice, and a private owned business. Sean from Drain Chasers was who we had just come out and gave me his personal cell phone number for if any other issues arise.
