Air Conditioning Repair Service near Inverness Dr. We were contacted by a homeowner in need of assistance with their non-operable air conditioning system. I promptly arrived at the residence to address the issue. After examining the system, I suspected the problem to be a refrigerant leak, so I completed a UV dye insertion to determine where the leak originated. After locating the leak I was able to seal it up and refill the refrigerant in the system to get it back in working order!

Air Conditioning System Installation near Robmar Rd. I was contacted by a residential client that needed a new air conditioning system for their home. I arrived after a consultation to install a new Goodman ductless mini split air conditioning system into the home. I carefully checked each component of the system and ensured that it was operating within the manufacturer’s recommended specs. The client was grateful to have a reliable source of cool air for the coming summer heat.
