We have used Timothy Off for years in plumbing maintenance and HVAC system maintenance. Recently our very old HVAC system stopped working and we turned to Timothy Off to replace it. They... were ready and willing to try to repair it and in no way pressured us to get a new one. Due to the age of our system we moved forward with replacing it. They were super clean, covering the floor, and wearing shoe coverings. Their employees are very knowledgeable in their areas of expertise and were happy to educate us. We will definitely be continuing working with them.read more

Our project was a big one - converting from oil heat to gas heat. Dan, the Project Manager, outlined all the steps involved clearly and precisely. During the entire process , he was readily... available for any communications.Frank led the team that did the installation of the new system. Everyone was extremely polite , courteous, and professional in their work. They provided updates on the progress of their work , explained what was next up in the process, and answered all my questions. The team demonstrated great pride in their work!When completed, I had a new gas heating system and a thoroughly cleaned up work area! Thank you!read more

Installed a 20 Seer Bosch HVAC (Heat Pump and Air Handler). Very informative and professional at sale and installation all at a fair price. Have used two of the larger suppliers of HVAC on... numerous homes over the last 30 years and this was by far a much better experience with no pressure to upsell like the others push. Would highly recommend them.read more

tldr: flat rate pricing, charged $1200+ for a 2-3 hour gas line replacement. Plumber was quick, knowledge, polite and cleaned up everything.Full:I had a slight gas leak which peco deemed... liveable but fixing the issue was a better option. Timothy Off said changing the pipes would be cheaper than fixing the old leaks. They said it would need some special connectors and if they touched the old pipes they would also be liable for any other issues. For these reasons the pipes were removed and changed to a different flexible material. The job was about 2-3 hours and looks like about 30ft of the flexible tube was used. The plumber said each feet of the tube was around $3-5. I was charged a flat rate of $1,274.50. With the numbers given above I would be charged $150 for the tubing and $1124.5 for 2-3 hours time and pipe removal. This is the main reason for 4 stars instead of 5; price.The plumber, Joseph, was professional, helpful, knowledgeable, quick and cleaned up the space well.The main office answered the phone quickly and returned my call by the next day for more information that I wanted. They do not report an itemized list for you as they charge a flat rate. The numbers I have above are not exact nor professionally calculated. I received the tube cost from one of Timothy's plumbers.I'm apprehensive to use Timothy Off next time because of the high cost. The plumbers' professional would be the reason for me to come back.read more
