Three things decide whether a homeowner trusts an HVAC company, and all three happen before a wrench comes out.
Northfield Mechanical carries a 10 year warranty on all manufacturer parts and a two year warranty on labour, with manufacturer coverage on the equipment sitting on top. Our Google reviews are public and the gallery shows recent installations across the GTA. Reviews are the clearest signal a homeowner has when choosing a contractor, which is why we ask every customer for one. Where a review flags something we got wrong, it gets dealt with rather than argued about, because the next homeowner reading it deserves an accurate picture.
The work splits into furnace installation and repair, air conditioning, heat pumps, water heaters, gas fireplaces, humidification, hydronic heating and annual tune up and maintenance. Urgent no heat and no cooling calls are given the first available slot. See the full service list or the brands we carry, or book an appointment.
