The Lower Mainland of Vancouver has a moderate, oceanic temperature, meaning that the fall and winter seasons are wet and cold. Due to this, from November to March, most citizens spend time inside and trying to stay warm and dry. 

To escape the cold, a proper furnace system with adequate heating capacity is essential. The size of the furnace is particularly critical as it directly affects the efficiency of your home heating system, your comfort, overall power consumption, and maintenance or replacement costs. 

If the furnace is too large, the system can overwork and wear out prematurely, too small and it won’t effectively heat your home during the coldest months.

Formula and Factors for Calculating a Lower Mainland Home Furnace Size

The general formula for a furnace size requirement is 30,000 BTUs per 1,000 square feet of home. However, it can be more tricky than that. 

One aspect you have to consider is insulation, as a well-insulated 2,000-square-foot home in Vancouver might require a different furnace size than a poorly insulated one of similar dimensions.  

Homes with higher insulation levels are typically more energy-efficient and require smaller furnace sizes to maintain a comfortable temperature. Proper insulation can also help maintain the warm air produced by the furnace inside the house, reducing energy loss and lowering heating costs. Beyond the insulation, there are other factors to consider, such as:

• The number of windows
• How much natural lighting you receive
• Building material
• Number of rooms
