I needed a formal document called Heat Loss/Gain Calculations for my newly built house to prove that the builder has undersized a furnace for our house. Builder did not agree with my claim, and I reported the issue to Tarion as warranty claim. David was able to provide me with Heat Loss/Gain Calculations that showed in fact the furnace installed in out house was undersized. It was a crucial piece of document to support my claim.
I am very happy with David performance.
I needed a building permit for my house. DA Heating Systems Solutions provided the designs I needed to get the permit. They did a heatloss calculation and a ventilation report. They also designed the duct work for the entire home and some infloor heating for bathroom floor warming. DA Heating Systems were professional and friendly! I strongly recommend DA Heating Systems!
