Dave in Kitchener

★★★★★ From the quote to the completion of our renovations, Delta was a dream to work with. I would wholeheartedly recommend these guys to anyone looking to replace their furnace or AC unit in Kitchener-Waterloo area. Never in my life has a renovation gone so smoothly.

★★★★★ The staff at Delta Air from sales to installation were professional and explained everything clearly, I was sold a great unit and a great price that was sized for my townhouse properly without trying to be over sold. The installation crew were friendly and did amazing work. Thanks! Highly recommend in Kitchener-Waterloo area
