Do not use CJ Air Solutions. While the service quality is O.K., their prices are set up to gouge the unsuspecting and desperate consumer. I was quoted $3,400 for a new 3 ton 13 seer A/C condenser. I had previously used them for another repair and now believe I was totally ripped off. After making numerous calls to other companies in the DFW area, I learned that the average price for this type of unit should be around $2,300. This was the typical quote from 5 various companies. However, I ultimately found Denco Services (www.dencoservices.com/ ) on the Internet. They have unbeatable prices due to their low extremely overhead. I called on a 100+ degree Monday afternoon and had a new unit installed on Tuesday. Same brand name unit, same warranty, and a 5 year warranty on labor. Denco Services has to be the best value in A/C repair in Dallas.
