I called air done right, because I needed a second opion on my large ac outside. Another company "Air Supply" told Me that my air conditioning system had a leak and were tried to sell my mom a 6500.00 air conditioner . They took payment even before job got started and charged her credit card . I didn't know they scammed me until air done right (Mark the supervisor ) told me there were no telltale signs of any leakage.
