John at Sharman Air Inc. is an excellent, responsible, knowledgeable and reliable worker for his company. He promptly helped us completely restore cold air back into our home. He quickly found the issues and explained to us why our home wasn't being cooled to its full capacity due to the fact that the previous company and worker did not connect our coil properly to push cold air through the home like it was supposed to. Call him for any HVAC services. He is amazing at what he does.
