Heating & Cooling Considerations For Markham Homeowners
Markham city has a bunch of local factors that directly affect how your home’s HVAC system performs. When installing a new air conditioner, buying a new furnace, or a heat pump, it’s important to consider some environmental and zoning conditions so your system is appropriately sized for your home. 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 Markham’s climate and zoning rules, 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.
