Twenty-two winters. Same phone number.
When it’s −34 and the furnace quits at 2 a.m., you don’t want a call centre. You want someone who knows your street.
Northwind started in 2004 with one van, one licence and a simple promise: arrive when we say we will, explain the problem in plain language, and charge the price we quoted. Two decades later that promise still runs the shop — now with six certified technicians and a truck stocked to finish most jobs on the first visit.
We’re not the cheapest quote you’ll get, and we don’t pretend to be. What we are is the crew that torque-tests every fitting, photographs the work, cleans the floor behind us, and answers the phone next February when you need us again.
Book a free, no-pressure assessment. If a repair will hold another season, we’ll tell you — even when a replacement pays us more.
