Timothy Off

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 more

Great experience from start to finish with our new Bosch family members! Dan (Project Manager) was great to speak with and provided ample information as well as straight forward answers and... most importantly did not make us feel forced or rushed into a decision. I let him know that I was waiting on another quote and he gave me space and provided information which I verified via Google to compare apples to apples for these quotes. He went above and beyond by matching the low end quote from the other company which was great. In turn this made us make the decision for the mid Range unit instead of the low end.The technicians who completed the install were great. They were very respectful of our house and made sure to use tarps and shoe covers during the install. They also left everything clean when they wrapped up. Very knowledgeable and easy to talk with.I was pleasantly surprised by how smooth the whole process was. I would highly recommend Timothy Off and hope you have a great experience as more

Expert Installation. As someone who has done sales my whole life, my comfort advisor Ken was excellent. He is not just another "sales guy", he is also a NATE certified mechanic who cares... about your home as if it was his grandmothers home. Ken did not try to immediately sell me the absolute most expensive system they offer, he looked at my ductwork, windows, attic insulation, and wanted to know how we use our system. After that, we decided on a 16 SEER AC and 96% gas furnace with variable speed. Once we decided on the new system, we set a date for the install. Considering the supply chain issues everyone is having, I was impressed that we got the job scheduled and done within a week. The most impressive part of this entire process is how well trained the install crew is. Chandler and Kelly came to my house at 8am exactly and after the introduction, they had drop cloths laid down from the front door, through my kitchen and down the stairs into the basement. As far as contractors go, they showed more respect for my home than any other company ever!! Near the end of the day, Ken actually sent the Service Manager Tyler over to actually start the equipment and went over everything with my wife and I. What other company would send a mechanic at the end of the day to start up a new system, even still the Service Manager? I look forward to many trouble free years with my new Trane HVAC system. They were not the cheapest quote I received, but they were close enough to where their quality and work ethic was well worth the extra price.
