If I could give more stars I would. I had a big sewer line issue and after dealing with other companies who would take forever to call me back, or not give a direct answer or estimate (this... went on for two months), I was recommended Timothy Off. Thank goodness. They had someone out within 48 hours, deduced the issue and had the job completed within two weeks. Everyone was a pleasure and extremely professional. The customer service was more

From day one, everyone that my wife and I had interacted with were friendly, professional and truly made us feel like they cared about the situation that we were in. The first person that... my wife had interacted with was Tyler, who supplied superior customer service. When I called and spoke to my wife about the visit, she was so happy with the service that she had received but more importantly how nice and professional Tyler was. I then met Dan who had come out to look at the current system we had and to look at the layout of the house to figure out what options we had. From the moment we met Dan, he truly made us feel like he cared and he went above and beyond to set up a time to have a install done as soon as possible. He was kind and caring. That day, we decided to move forward with Timothy Off. The day of the install, we then met Kelly, Chandler and Ryan who were very professional, caring and nice. They did excellent work and provided superior customer service. We are so happy with everything!!read more

Most honest company I have ever dealt with. Was taken advantage of by a big competitor of theirs and glad my friends recommended I switch to you.

Needed a new HVAC system (AC and Heating) about a year ago. I had several local vendors come quote us. Timothy Off sent Dan Lippin. From beginning to end, he was professional,... knowledgeable, and honest. Other vendors tried to sell me on unnecessary "deals" and "features." Dan broke it down and sold me what I needed.I have now had the system for a year. Service through Timothy Off has been pleasant and reliable. I am 100% satisfied at this time. I highly recommend Timothy Off for your HVAC needs. If you are fortunate enough to have Dan as your Project Manager, you won't be more
