How Furnace Size and BTU Output Impact Installation Costs in Ontario
The cost of a new furnace in Ontario is heavily influenced by its BTU output and size directly impacts both installation costs and long-term efficiency in Ontario homes.
For a typical 1,500-square-foot house, you’ll need a furnace with 45,000 to 72,000 BTUs, costing between $3,500 and $5,000 installed. The larger your home, the more BTUs you’ll require.
A 2,000 to 2,500-square-foot home generally requires 80,000 to 100,000 BTUs, with installation costs ranging from $4,500 to $6,500.
When selecting your furnace size, consider factors like ceiling height, insulation quality, and local climate conditions. Choosing the right BTU output is essential, as an oversized unit will cycle too frequently, while an undersized one won’t adequately heat your space.
Labour Costs for Furnace Installation: What to Expect
Labour costs for furnace installation in Ontario typically vary in urban areas, such as the GTA, and slightly less in rural regions. Additional costs may include permit fees and ductwork adjustments, particularly if you’re upgrading to a high-efficiency furnace.

Additional Expenses to Consider During Installation
Installing a new furnace involves more than just the unit and basic labour costs.
You’ll need to take into account potential expenses for permits, which are required by most Ontario municipalities for HVAC installations. Additionally, you might need ductwork modifications or repairs to accommodate your new system.
Some homes may require electrical upgrades to support a new furnace, especially when switching from an older model to a more advanced unit.
You’ll also want to factor in the cost of removing and disposing of your old furnace, as well as any necessary venting system updates to meet current safety codes.
If you’re planning a furnace installation, it’s wise to budget for a carbon monoxide detector, thermostat replacement, and possible condensate pump installation.
These additional components guarantee your new heating system operates safely and efficiently.
Key Factors Affecting Furnace Installation Costs
When you’re planning to install a new furnace in Ontario, several key factors will influence your total installation costs, including your home’s size and layout complexity.
Your home’s square footage directly impacts the size of the furnace you’ll need, with larger spaces requiring more powerful units that come with higher price tags. Experts recommend using 30 BTUs per square foot when calculating your furnace requirements.
The installation complexity, combined with regional pricing variations and labour costs across Ontario, can greatly affect your final investment in a new heating system. Gas furnaces typically range from CAD 2,500 to CAD 5,500 for a complete installation package.
How Home Size and Layout Impact Installation Complexity
The size and layout of your home play a significant role in determining furnace installation costs. Larger homes require more powerful furnaces, which typically come with higher price tags, while complex layouts may necessitate additional ductwork modifications or special installation considerations.
| Home Size (sq ft) | Installation Complexity Level |
|---|---|
| Under 1,000 | Low to Moderate |
| 1,000 – 2,000 | Moderate |
| 2,000 – 3,000 | Moderate to High |
| 3,000+ | High |
Multi-story homes often present unique challenges, as the furnace must effectively distribute heat throughout different levels. Your home’s existing ductwork configuration, accessibility to installation areas, and the location of gas lines can also impact the overall complexity and cost of the installation process. At ALP Heating, we’ll assess your home’s specific requirements to provide an accurate installation quote.
Selecting the Right Furnace Size for Your Home
To guarantee accurate sizing, you’ll need a professional load calculation that considers your home’s specific characteristics, including ceiling height, air leakage, and local weather patterns.
This precision helps prevent inefficient operations and unnecessary expenses. Having an oversized furnace can result in short cycling and wasted energy.
Industry experts recommend using 30-45 BTUs per square foot of living space for homes in colder climates like Ontario.
Understanding Furnace Efficiency and Its Effect on Costs
Furnace efficiency ratings play an essential role in determining both your initial installation costs and long-term operating expenses.
Modern furnaces are rated by their Annual Fuel Utilization Efficiency (AFUE), which ranges from 80% to 98%. While high-efficiency furnaces (95-98% AFUE) cost more upfront, they’ll save you considerably on monthly energy bills over time.
In Ontario’s climate, investing in a high-efficiency furnace often makes financial sense, especially if you’re planning to stay in your home long-term.
A 96% AFUE furnace, for instance, wastes only 4% of the fuel it consumes, compared to a 20% waste rate in an 80% AFUE model.
You’ll need to balance the higher initial investment against potential energy savings, considering factors like local fuel costs and your home’s heating demands.
Labour Costs and Regional Pricing Variations in Ontario
Several key factors influence labour costs for furnace installation across Ontario, with significant variations between urban centers like the GTA and rural areas.
In major cities, you’ll typically pay between $1,000 to $1,500 for professional installation labour, while rural areas might see lower rates due to reduced overhead costs.
Installation complexity plays a vital role in determining your final labour costs. If you’re replacing an existing furnace with a similar model, you’ll likely pay less than if you need new ductwork or electrical upgrades.
Your home’s layout and accessibility to the installation area can also impact labour charges, as difficult-to-reach spaces require more time and effort.
At ALP Heating, we offer competitive labour rates across the GTA, ensuring transparent pricing and professional installation by our TSSA-licensed technicians.

How to Choose the Right HVAC Contractor for Furnace Installation
When choosing an HVAC contractor for your furnace installation, you’ll want to verify their licensing and certification to guarantee they meet Ontario’s safety standards and regulations.
It’s crucial to get multiple quotes from different contractors, allowing you to compare prices, warranties, and installation timelines while understanding the full scope of services offered.
You should also check references, read online reviews, and look for contractors with proven track records of successful installations, such as those with high ratings on platforms like HomeStars or Google Reviews.
Ensuring Licensing and Certification for Quality Work
Checking a contractor’s licensing and certification status should be your top priority when selecting an HVAC professional for furnace installation.
In Ontario, HVAC contractors must be TSSA-licensed to legally perform furnace installations and repairs, ensuring they meet strict safety and professional standards.
When evaluating potential contractors, don’t hesitate to ask for proof of their licensing and certifications.
Reputable companies, like ALP Heating, employ TSSA-licensed professionals who undergo regular training to stay current with industry standards and safety protocols.
You’ll want to verify that your chosen contractor maintains proper insurance coverage and follows local building codes.
Why Comparing Multiple Quotes and Checking References Matters
Getting at least three detailed quotes from different HVAC contractors helps you make an informed decision about your furnace installation investment.
When comparing quotes, make certain each one includes equipment specifications, labour costs, warranty details, and estimated completion time. This allows you to evaluate value rather than just price.
Don’t hesitate to ask contractors for references from recent furnace installations, and take time to verify these references. You can also check online reviews and ratings on platforms like HomeStars, where reputable companies like ALP Heating maintain strong reputations with numerous five-star reviews.
When speaking with references, ask about the contractor’s punctuality, professionalism, cleanliness, and whether the final cost matched the initial quote. This due diligence helps guarantee you’re choosing a reliable contractor who’ll deliver quality work.
