Furnace repair in Markham

Furnace Repair in Markham

North Wind HVAC provides furnace repair in Markham, including Unionville, for furnaces that produce no heat or leave parts of the house colder than others. The usual causes are a thermostat or wiring fault, a tripped limit switch, a failed control board, or a blocked condensate drain or vent.

A limit switch trips when the unit overheats, and a blocked condensate line or vent can lock the furnace out for safety, so clearing the cause matters more than resetting the system. Our technicians test each possibility in turn, explain the fault and provide an estimate before proceeding.

After the repair, we run the furnace through a full cycle to confirm it heats evenly and shuts off properly. Some faults are resolved during the first visit, while a failed component that has to be ordered calls for a follow-up visit.

AC Repair in Markham

An air conditioner that runs continuously without reaching the thermostat setting is not necessarily too small for the home. In Markham, North Wind HVAC investigates whether reduced cooling comes from restricted airflow, dirty coils, a malfunctioning fan, or a refrigerant problem.

Our technicians inspect the thermostat, indoor airflow, outdoor condenser, and electrical components. We measure temperature differences, check compressor and fan operation, and assess refrigerant conditions when necessary. The diagnosis and repair estimate are explained before proceeding.

Repairs may include replacing a capacitor, contactor, or fan motor, cleaning an obstructed coil, or correcting a refrigerant leak. Once completed, we check that the system maintains steady cooling without excessive cycling.

Furnace and AC installation in Markham

Furnace and AC Installation in Markham

A new heating or cooling system should work with the home’s existing infrastructure, not simply fit the space left by the old equipment. North Wind HVAC installs furnaces and air conditioners in Markham, accounting for capacity, ductwork compatibility, ventilation, and system performance.

Our technicians inspect the current installation and assess whether the ductwork can support the airflow the replacement equipment needs. We also consider the home’s insulation, layout, and heating and cooling needs before recommending a unit.

Installation involves removing the old equipment, preparing the connections, and fitting the new system to manufacturer requirements. Before finishing, we check the controls, airflow, and temperature performance with the home’s existing setup.

Heat Pump Installation and Repair in Markham

A heat pump must match the home’s heating and cooling requirements to perform efficiently year-round. North Wind HVAC installs and repairs heat pumps in Markham, including central ducted systems and ductless units for homes where ductwork is impractical.

During installation assessments, our technicians examine existing equipment, airflow capacity, electrical supply, and heating and cooling needs. Central systems must be compatible with existing ductwork and backup heating.

For repairs, we investigate poor temperature control, unusual noises, refrigerant leaks, and communication faults between indoor and outdoor components. Testing shows whether the problem is in the controls, airflow, or refrigeration system.

Moved into a new home and A/C was not working, had someone else in come in and made things worse, then I had no heat. North Wind came out and assessed the damage and had my heat and air running as good as new within the hour, he even explained the new thermostat (as different from my last one) and even made sure the heat and air were both working well. I was very impressed, extremely knowledgeable, wished we would have called him first. 100% would recommend!!

The BEST Professional service at a value price. My furnace broke over the weekend. I called North Wind Heating and technician came very quickly, identified the issue, brought and installed the required part very quickly without any delay so the heat was restored with minimal interruption. Last summer they fixed my air conditioner, the same way: quick and professional. Highly recommend!

I am very happy with the service I got from this company. They came in a timely manner, and provided me with options, including taking pics of warranty and service schedules. My heat exchanger was still under warranty, even though it was old. They installed it quickly and cleaned up after themselves, were polite and professional.

Absolutely the best heating/air conditioning company in the Barrie/Innisfil area. My furnace stopped working the other day during a cold-snap, but Northwind Heating/A.C. promptly sent a service technician to my house to fix it for me. They are honest, hard working guys that truly care about customer service and customer satisfaction, (which is rare these days), and I couldn't be happier with the quality of service they've provided. Pricing is very fair too, they don't try to rip you off. There's a reason this company is rated so highly on Google reviews, it's because they really are the best. If you need any work done on your heating/AC unit, I highly recommend giving Northwind a call. Awesome team. Thanks guys!

I had no heat at my cottage. Had two companies try to repair it. They had no idea. North Wind came (on time) and repaired it in record time. There was no issue knowing what to do and how to do it. I was very impressed and very happy. I HIGHLY recommend this company. I will definitely use him again and will continue to recommend North Wind. Thank you for the excellent service.
