They added freon to my outside central ac unit but never checked the unit for a leak. In less than 24 hours all the added freon leaked out and we were back to square one. We agreed to purchase a new unit from them but they never showed up for partial payment. We called another ac company and a defective valve was replaced in less than 30 mins and more freon was added. We now have cold ac without having the outside unit replaced. Oh and they charged me over $ 300.00 for the«repair». What a waste of time and money! Avoid this company!!! They are rip-offs!!!
