Air Conditioning Repair near Bob-O-Link Rd. I responded to a call for a client whose a/c system was malfunctioning. When I arrived, I found that the system was producing a strange noise. The unit's compressor was found to have become loose when the system was investigated. To get the compressor back in working condition, we replaced the bolts. The A/C unit is now working well again, and the noise has been eliminated.
