heating & air conditioning/hvac
 + -1 moreWe were very disappointed with Diagnostic's service on our heat pump. Customer service, professionalism, and quality of work was extremely poor. We had to spend a considerable amount of money to repair the work done by Diagnostic. They installed the wrong size air handler and a far too small drain line which led to secondary damage to our home in the way of leaks thru walls and ceilings. They neglected to charge the unit with refrigerate. It took the contractor weeks to make this repair during the coldest part of the year. We raised these concerns and the contractor and he refused to correct the problems. It was pretty clear that the contractor was not very knowledgeable or experienced. We DO NOT recommend this contractor.
Description of Work: Very POOR Servicing of heat pump
