 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.

AC & Furnace Considerations For Markham, Unionville & Surrounding Neighbourhoods

Whether you live in Markham, Unionville, or anywhere surrounding, considering local conditions will help make sure you install the right type and size AC, furnace or heat pump system for you. Let’s go through these considerations to factor in for your home heating and cooling needs:

Climate & Plant Hardiness Zone: Markham is located in Plant Hardiness Zone 6a, where winter temperatures can drop as low as -23.3°C and summers often bring high heat and humidity. You would need a furnace that provides 50–55 BTUs per square foot, paired with an air conditioner or heat pump.
Urban Conditions: As Markham sits within the Greater Toronto Area, homes can face either suburban cold or heat buildup on either side of the extremity. This combination means that installing an energy-efficient furnace and AC is essential.

By considering local climate, you’ll not only choose the right HVAC system for your home but also save money on future repairs and energy costs. North Wind provides FREE in-home consultations throughout Markham to help you select the best unit for your home and ensure it meets local requirements.
