We hired M&S HVAC to replace our unit last year. Well guess what it is not working now. We had 2 other technicians from other companies come over to check what's wrong and they both mention that whoever installed our unit did a really lousy job. He failed to properly weld the pipe which caused oil to leak leading to the compressor failure. The other technicians also mentioned about other problems about the pipes making couple of right angle turns which is wrong. They should have been straight. Beware of this guy named Roger.
