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 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.
