Mark recently completed a demanding HVAC project for us which spread over almost 3 months and involved numerous changes in plans along the way. Our conversion of a residential basement into a legal apartment required the separation of heating and ventilation systems. The design resulted in a combi-boiler driving radiators in the apartment, a forced air "air handler" for upstairs and a switch to demand domestic hot water, eliminating a tank. A replacement AC unit was also part of the install.
Originally we had spec'd a traditional gas furnace for upstairs but later changed to the air handler to save space and make better use of the boiler. Mark had experience with this unusual approach (for residential) and was able to accommodate the change well after the original quote had been accepted without issue.
Mark was also very flexible with being able to absorb surprises such as having to relocate our electrical panel, move a HRV unit location, and repeated gas connection alterations. Helping us through unexpected changes made our renovation less stressful and demonstrated Mark's professional approach to his work. We are very satisfied with our HVAC system and are confident that the work was done "right".
