What Our Customers Say
Don't just take our word for it. Here's what homeowners across Toronto have to say about their experience with Northfield.
"Our furnace stopped working on one of the coldest nights of the year. Northfield had a technician at our door within two hours. He found the problem quickly and had us warm again before bedtime. Fair price, no pressure, just good honest service."
"We've used Northfield for years and they've never let us down. They installed our new AC last summer and the difference is incredible. The team was professional, cleaned up after themselves, and the price was exactly what they quoted."
"I called three companies for quotes on a new furnace. Northfield was the only one that took the time to explain my options without pushing the most expensive system. They helped me choose what made sense for my home and budget. Highly recommend."
