 Trustindex verifies that the original source of the review is Google. We have used North Wind HVAC for a vent repair and a full install of a new furnace. The technician was extremely thorough, knowledgeable and provided cost effective options. Moreover, they responded quickly and visited our house in short notice despite a huge snow storm.

In today’s world where it can be difficult to find a reputable and trusted technician/ contractor, I was very impressed by their overall customer service and expertise. I have already recommended them to friends/ family and would highly recommend to anyone in need of HVAC repair.

 Trustindex verifies that the original source of the review is Google. Alex was great. My furnace stopped working on a Sunday in the middle of a cold snap.  Alex came out within 2 hours, diagnosed the problem, and had the furnace company send the part as it was under warranty.  Him and his technician were prompt, knowledgeable and got the job done. I would highly recommend using North Wind HVAC.

That “Why Is the House Still Cold?” Moment

Furnace Repair in Mississauga

We help Mississauga homeowners get their heat back quickly with same-day and emergency furnace repair, carried out by local technicians who work on these systems every day.

From older homes in Cooksville and Port Credit to newer builds around Meadowvale and Erin Mills, our TSSA-certified gas technicians can fix your furnace. Backed with a comprehensive warranty, once it’s sorted, you don’t have to think about it again.

Local Repair Technicians Experienced in Fixing…

Furnaces blowing cold air

Often caused by ignition, airflow, or thermostat issues, this is one of the most common problems we see during winter service calls.

Furnaces that won’t turn on

This can point to electrical issues, safety switches, or failed components that require proper diagnostic testing.

Strange noises or unusual smells

Rattling, banging, or burning smells can indicate loose parts, motor issues, or combustion concerns that shouldn’t be ignored.

Short cycling or frequent shut-offs

When a furnace turns on and off too often, it may be overheating or struggling with airflow or sensor problems.

Weak airflow or uneven heating

Common in both older Mississauga homes and newer ducted systems, often related to blower or distribution issues.

When Your AC Sounds Like It’s Struggling

Air Conditioner Repair in Mississauga

Our technicians are trained to service all major AC makes and models, using OEM parts where applicable and providing warranty-backed repairs.

If your system is beyond repair, we also offer free in-home consultations to help you explore replacement options, with honest advice, not pressure.

Team Of Repair Specialists Who Can Fix…

AC running but not cooling properly

This is often related to refrigerant levels, airflow restrictions, or failing components that affect performance.

Warm air coming from vents

Can point to compressor issues, refrigerant problems, or thermostat communication errors.

AC unit not turning on

Electrical faults, capacitor failure, or safety shut-offs are common causes, especially during high-demand days.

Unusual noises or vibrations

Buzzing, grinding, or rattling sounds may indicate loose parts or motor issues that need attention before further damage occurs.

Water leaks or excess moisture

Drainage issues or frozen coils can lead to leaks, which are common during humid Mississauga summers.
