I have been using Timothy Off for HVAC services for the last 5 years and they have done an outstanding job. When I moved to West Chester I had a Fugitsu ductless split system installed... which was warranted for 1 year. Unfortunately every year for 4 years it would loose its Freon and had to be recharged. The Techs could not find a leak and we kept hoping it would be fine but it was not. This May, Tim agreed to replace the system with a Mitsubishi system……free of charge. It is now working great! Tim is an honorable man who stands behind his work and goes over and above to make his customers happy. His Techs are great too! If you need HVAC work done, I highly recommend Timothy Off Heating and Plumbing Services. Bonnieread more
