I would highly recommend Nolan and his staff, they went above and beyond with getting us a new furnace and replacing all of our old ducting. We can now comfortably enjoy every area of our home without needing space heaters
Sub Zero replaced our existing heat pump with a new variable speed unit and we are very impressed with how quiet it is especially in cooling mode. We have noticed a reduction in our Hydro costs since the installation. Nolan and his team did a great job
We set out at the start of every job we do to ensure that the work is done on time, with the right products, and that it’s done right the first time.
