We had to replace our old boiler system (we have rads in our 1917 Toronto house) and we got several quotes and recommendations about how to proceed. We decided to go with Paul at Ductless.ca because he provided the most detailed and thoughtful quote for us based on what he felt would be most suitable for our house. We had our boiler and our hot water tank replaced with a combi boiler PLUS the install crew (Andy and his assistant Carl) removed and cleaned up a lot of the (ancient!) piping. The best thing is that the installation took place over 3 days (they started the first day in the mid-afternoon after completing another job) and Andy made sure we always had hot water for dishwashing and showers overnight, so no inconvenience to us trying to get a busy family going in the morning. Excellent service from Paul, he came with the crew on the first day, and came by several times during the installation process to check on things. Very much appreciated.
