We built on a room addition this past summer. For the heating and cooling aspect of the job, our contractor obtained an estimate from his usual HVAC contact person. That person wanted to add entire new furnace and a/c units just for the 380 sq ft room. So I had my contractor request an estimate from Polestar which I have used for almost 25 yrs. Polestar came out, assessed the situation, said my existing furnace and a/c could handle the additional space, sumbitted a reasonable estimate, and landed the job. And they did a GREAT job installing the needed duct work. The temperature in the new room has been comfortable throughout the different seasons.
