Scott was part of a joint install with Shift Air Mechanical Ltd. To install my A/C. Scott Installed the Condensing Coil in the Furnace and did an impressive and neat job. The most common reason A/C unit fail is poor installation. He is extremely knowledgeable of HVAC systems and different controls. He answered all my questions and Informed me of do's and dont's of A/C systems. He's is very professional and even knew to advise me of smoke alarms being triggered and calling the Alarm Company while he was soldering the copper tubing beforehand.
