What Our Customers Say
Real feedback from homeowners across Oakville, Mississauga and Milton.
"Our over-the-range LG microwave stopped heating completely. Insta Fix came the same day, diagnosed a faulty magnetron and had it repaired quickly. Knowledgeable technician, fair price and no mess left behind."
"The Samsung microwave started sparking inside and I switched it off immediately. Insta Fix arrived the same afternoon and found a damaged waveguide cover. Replaced it on the spot. Efficient and reassuring service."
"Turntable stopped working and the touch panel was glitchy on our Whirlpool microwave. Both issues fixed in one visit. The technician took time to explain the repair. Couldn't ask for better service."
