Reviews From Dundas & Nearby
“Our AC quit at 9pm on the hottest night of the year. Smith answered on the first ring and had a technician at our Dundas home before midnight. Bad capacitor, fixed on the spot, price quoted before he touched anything.”
“Same day AC repair, exactly as promised. Tech wore shoe covers, explained the frozen coil, cleaned the drain and had us cold again in about an hour.”
“Our heat pump kept icing over. The technician diagnosed a failed defrost board, had one on the van, and walked me through preventing it next winter. Great communication start to finish.”
