Do not use this company. The wife/Business office manager is very rude, untrustworthy and unprofessional. They tell you that you have to pay for materials and parts and then use your old parts. She even threatened to try and put a lien on my home for non payment of materials when they used all of my existing material for a compressor, My warranty company is also going after them for unwarranted charges. They pray on you and your warranty company if you don't check behind them. Beware!!!!
