Jeremy arrived on time for an emergency repair to our HVAC cooling system. Apparently, the water drainage system to the outdoors had a clog and the system shut off was activated to prevent any water spillage.Jeremy cleared the line and the HVAC turned on. He was thorough and explained each step. Great job!
