We just had a 20+ year old HVAC system and water heater replaced by Timothy Off HVAC. The entire experience was great! The initial visit by Dan to discuss our options was amazing. Just an... honest evaluation and discussion with no pressure. The installation was scheduled quickly. The crew that did the installation were awesome. They were all very professional and willing to answer any question you might have. When they were finished, the entire are was completely clean.I am very pleased with the work and the staff at Timothy Off HVAC. I would highly recommend them for your HVAC or plumbing needs.read more

Just had an entire new HVAC system installed in my home. Contacted Timothy Off to schedule an estimate and was told a representative will be out in one hour. Dan Lippin arrived and was... completely professional, knowledgeable, and gave us a price we could live with. One day later, an army of technicians arrived to install the new unit and we were backup and running within hours. I highly recommend this company!read more

My home was in need of a complete Heat Pump system. I obtained 3 estimates and made a decision to hire Timothy Off - it proved to be a good choice. From start to finish it went ABSOLUTELY... smooth!Met w/Dan, the Project Mgr, who answered all my questions, he was kind and knowledgeable. The project moved frwrd to the day of installation: the 2-man crew (Bryan and Nate) were punctual, friendly, knowledgeable and did an excellent job cleaning up upon completion!The installation was finalized within the estimated time frame and was followed-up by Brian who tested and fine-tuned all the aspects of the heating system, he then installed the thermostat and instructed me on how to operate it.Even the Project Mgr, Dan, stopped by that day to make sure everything was going well. Dan went above and beyond by assisting me with some shelving that needed to be re-positioned and rehung.Thank you Timothy Off, job well done by everyone involved!!read more
