The guys from Spring Woodlands Air Technicians did a good job of getting my system to work. The only thing I have to complain about was that they didn't put down anything on floor while they were working. They left 3 dirt spots on the floor. I'm not too happy about that. I am happy with how much it ended up costing me. I had 2 other companies come in and evaluate my system. A new system from them was going to be $12,000 - $19,000. SWAT came in and said I just needed to wrap my pipes to get my old system running. So, it only cost me $500. They also gave me a price for a new system of around $5000, which was less than half of what the other 2 companies told me. I would use them again and I have recommended them to other folks.
