I had to have a complete HVAC system replacement. I got proposals from 4 companies and after much research and many inquiries, I chose Timothy Off. The pricing was competitive and... provided the best value for my money. I was also impressed with Kenny Denson, my primary contact, who was great to work with. He answered my many questions in a professional and forthright manner, which I really appreciated. The installation team was just as impressive, arriving on time, answering all of my questions and leaving the place spotless afterwards. The entire team was professional, courteous and respectful of my home. I had a really positive experience with Timothy Off from beginning to end. I rarely write a review, but this company deserves 5 stars and my high recommendation!!!read more

From sales to installation, we are very satisfied with Timothy Off. Their price for installing a new heat pump was competitive, they installed it on schedule and had the system thoroughly... checked out after installation. Kenny followed up promptly when we asked them to repair a small hole that was left in our foundation wall from the old A/C unit. Best of all, they did a detailed heating and cooling load analysis to properly size the heat pump when the other firms we contacted would not. Timothy Off will definitely be the first call we make when it comes time to replace our water more
