We were very pleased at the speed, professionalism, and follow up with our central AC installation. One extra nicety was that, upon realizing that our attic access was going to be too small... for the size of the equipment, the company arranged for - and made part of the overall service fee - the services of a contractor to install pull-down steps in a larger access opening. Very easy process all around and the house is very comfortable as the hot weather is just about to start.read more

Needed a new HVAC system (AC and Furnace). I received 3 estimates and went with Timothy Off.Met with Dan the Project Manager who was awesome to talk with. He answered all of my questions... and provided me with more relevant information which helped scope the overall project. Dan was honest and provided a lot of value as I compared the 3 companies/bids. Install was setup for later that week and the Installation Crew (Tim and Nate) arrived on time, were friendly and professional and kept my house very clean. After install, a Technician (another Dan) arrived who tested and fine-tuned the entire system (AC and Heat). He walked my wife and I through the system and how to work the new Thermostat which was very helpful. One other point to note is the Project Manager Dan stopped bye during the installation to check up on how things were progressing and even brought the installation crew Gatorades.I would highly recommend Timothy Off.read more

The entire team at Timothy Off made me feel like I was a VIP customer. They were exceedingly patient and explained everything in layman's terms. I got 8 different estimates and Timothy... Off provided the best value for the price. They installed a new HVAC system on a very rainy day and had to trudge through a lot of mud in my backyard, but they kept my house clean. I would absolutely recommend Timothy Off and plan to hire again for any of my future needs. I never felt pressured into making a decision and appreciated the team's willingness to work with me/educate me on the entire process.read more

Timothy Off was great! They came out quickly when I realized my heater was not running right and diagnosed the problem. I had to have an HVAC system replacement. The team that they sent was... knowledgeable and answered any questions I had. They did great work and were very neat and clean (they cleaned up so well it looked like they were never there). Dan was great with keeping me updated and keeping in contact to help with any questions I might have - he even stopped by during the install to make sure everything was going well. Thanks Dan and team!read more

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
