The technicians for Tiger Plumbing, Heating, Air Conditioning, and Electrical Services are superb! I had a warranty issue with my HVAC unit; it needed to be replaced. The project manager was very difficult to deal with. I bypassed him and went to upper management to get my issue resolved. Everything worked out to my satisfaction thanks to upper management taking the necessary steps to ensure that I was happy. I still use them and wouldn't hesitate to refer them. My only advice to this company is to let the project manager know that he needs to communicate with his customers and clients. Other than that I am sufficiently satisfied with my service.
