What our customers are saying



I was having problem with my heating at 1 AM in the middle of the winter. It started getting cold and since have kids, we had to get someone in to fix it. True North HVAC came within the hour and had our heat up and running!


True North HVAC helped us find and install a new water heater because we didn't want to rent one. They helped us save time and money, and above all, did a very clean installation.


We needed an air conditioner installed in our new home and True North HVAC was able to have it done within the week after our call. They were very professional and friendly.
