My 25 year old A/C system developed a slow leak in the condenser which caused a lot of water damage. Total Home Comfort was recommended by a contractor - Square Footage Inc., that was remodeling my kitchen. They came out the day after I called & diagnosed the problem quickly and gave me the option of a repair or replacement of the A/C. As the system was at least 25 years old I opted for a new unit. I researched their quoted unit & found the price quite reasonable. They also pointed out problems with the duct work in the furnace area, and included a complete replacement which was included in this price. Their work was quick and very tidy. I had a problem with the set up of my humidifier (unrelated to their work) and they were happy to come a month later & set it up for me. Considering their location in Ajax & mine in Toronto I found the 1 hr. charge very fair.
