The High Tech Difference

Our company operates on a philosophy of treating our customers the way we would want to be treated. We invest into our equipment and our employees to assure that each visit earns a 5-star review.

HiTech has excellent customer service. Their technician George is very knowledgeable and does a great job of explaining everything. Their summer AC-winter heating system service plan is great value.

Brian did an excellent job addressing a concern I had. I could sometimes smell a little natural gas smell when the furnace kicked in. He tracked it down and worked hard to fix it! I appreciate his efforts -- he went above and beyond to make sure that it was fixed right and I was satisfied. Thank you for the quality work!

My furnace wasn’t working on a cold February day, they were at my house within an hour. George P was fantastic he not only fixed the problem he gave me a lot of great tips too.

Brian is awesome! Very courteous. We have an older HVAC system and he worked to find the needed parts. He kept us well informed of the repair process. Abided by the mask mandate without our asking.
