"Joe was able to correct the problem while I was away. It's hard to get reliable contractors on the east end of long island on the north fork. He replaced the parts with a better set up where I could remove parts of my oudoor sink for the winter. He took pictures of the final job and emailed them to me. Price was very reasonable. I'm very satisfied overall."

"APV Mechanical got onto the roof of my business and checked the a?c compressor and discovered that the "main" circuit breaker required replacing. They also checked the breaker panel breaker and found it to be functioning correctly. They then went to the air handler and discovered that the thermostat was not sending the necessary signal to the air handler. They repaired the problem and the a/c  is functioning as it should.
I will definitely use them again should the need arise.
