Air Conditioner Repair in Edgewater, MD 21037

“Was very thankful that JC was able to come out on a Sunday morning promptly at 9:00 am, especially because the previous 2 days had been in the high 80’s. He quickly diagnosed the problem (bad compressor), replaced it, and cool air coming out of the vents by 9:45. He was friendly, courteous, professional, and worked quickly.”
