1. What is the Furnace Size Calculator?

The Furnace Size Calculator Alberta estimates the required furnace capacity in BTU (British Thermal Units) based on your home's heated area, insulation quality, window efficiency, and Alberta's specific climate zones. Proper sizing is crucial for efficient heating and comfort.

2. How Does the Calculator Work?

The calculator uses the furnace sizing formula:

\[ BTU = (Area \times 25) + \text{Adjustments for insulation/climate} \]

Where:

\( BTU \) — Required furnace capacity (British thermal units per hour)
\( Area \) — Heated square footage of your home
\( Adjustments \) — Factor for insulation, windows, and Alberta climate conditions

Explanation: The base calculation of 25 BTU per square foot is adjusted for Alberta's cold winters, with additional factors for insulation quality, window efficiency, and specific regional climate conditions.

3. Importance of Proper Furnace Sizing

Details: Correct furnace sizing ensures optimal energy efficiency, consistent comfort, proper humidity control, and extended equipment lifespan. Oversized furnaces short-cycle, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Enter the total heated area in square feet, select your home's insulation quality, window type, and your specific Alberta climate zone. The calculator will provide the recommended furnace capacity in BTU/h.

5. Frequently Asked Questions (FAQ)

Q1: Why is furnace sizing important in Alberta?
A: Alberta's harsh winters require properly sized furnaces to handle extreme cold temperatures while maintaining efficiency and comfort.

Q2: What are the consequences of an oversized furnace?
A: Oversized furnaces short-cycle (turn on/off frequently), reducing efficiency, increasing wear, and causing temperature fluctuations.

Q3: How accurate is this calculator?
A: This provides a reliable estimate. For precise sizing, consult with a qualified HVAC professional who can perform a Manual J calculation.

Q4: Should I consider other factors beyond square footage?
A: Yes, ceiling height, number of windows, door quality, and home orientation also affect heating requirements.

Q5: What's typical for Alberta homes?
A: Most Alberta homes require 40,000-120,000 BTU furnaces depending on size, with northern regions typically needing higher capacity units.
