“
We recently had a heat pump installed in our garage along with a propane heat blower and we couldn't be happier with the results. The entire process was smooth and start to finish. Zack was knowledgable punctual and took the time. Page explain how everything works and how to get the best performance out of our system.<br><br>The heat pump keeps the space at a comfortable consistent temperature and a propane heater is a great back up for a really cold days. Insulation was clean and well organized
