Red Flags: When to Retire Your Furnace
Before talking money, let’s talk timing. Your furnace is a silent workhorse, but it will eventually give up the ghost. Watch for these telltale signs that a new installation is on your horizon:
- The Age Factor: Most furnaces have a lifespan of 15 to 20 years.
- The Repair Loop: If you are calling an HVAC technician for furnace services more often than your best friend, those labour costs are better spent on a replacement.
- Bill Shock: Unexplained spikes in your utility bills often mean your outdated system is working overtime just to provide a whisper of warmth.
- Odd Noises and Odours: Popping or screeching are signs of internal distress, specifically a cracked heat exchanger, that a simple tune-up won’t fix.
Breaking Down the Furnace Cost and Installation
In Ontario, the average cost for a new heating system typically lands between $3,500 and $8,000. However, when asking how much does it cost to install a furnace in Canada, the answer can vary depending on the following factors.
| Feature | Impact on Cost |
| Type of Furnace | Natural gas furnaces are common, but oil furnaces or propane furnaces may be needed in rural areas. |
| Energy Efficiency | A high-efficiency model with a high annual fuel utilization efficiency (AFUE) rating costs more upfront but lowers energy consumption. |
| Furnace Size | A licensed HVAC professional must size furnace units correctly based on your home’s heating capacity. |
| Installation Complexity | New gas lines, electrical hookups, or duct modifications will increase the total installation costs. |
⇨ Pro Tip: Don’t forget the “hidden” help! In 2026, Ontario homeowners can access tax credits and energy rebates for installing energy-efficient furnaces. We help you navigate these to ensure you get every dollar you deserve.

The Professional Process: Our “Human Approach”
When you choose LG Home Comfort to install new heater systems, you aren’t just getting a machine; you’re getting a team of licensed technicians.
We handle the heavy lifting so you don’t have to.
1. Assessing Your Home
We don’t do “guesstimates.” An HVAC technician visits your home to perform a load calculation. This ensures you get the right furnace for consistent warmth without wasting energy.
2. Preparing and Removing Your Furnace
On installation day, we treat your home like our own. We safely perform the removal of your old furnace, ensuring all gas lines and electrical connections are handled with professional care.
3. Installing with Precision
Our team positions the new furnace to ensure it meets all local building codes. We check the heat exchanger, secure the electrical panel connections, and confirm the furnace and air conditioner work in harmony if you have a combined system.
4. Testing for Peak Efficiency
We never just “plug and play.” We run the new unit through a full start-up cycle to ensure your furnace efficiency is optimized. Finally, we show you how routine maintenance keeps your high-quality furnace running for years.
Why Professional Expertise Trumps DIY
It might be tempting to treat a furnace like a DIY weekend project, but the risks are severe. Gas furnace installation, for example, involves high-pressure gas and complex wiring. A mistake can lead to fire hazards or carbon monoxide risks.
Furthermore, most manufacturers require a licensed HVAC professional to maintain the warranty’s validity. At LGHC, our licensed technicians provide the advanced technology and innovative design your home deserves with the best performance guaranteed.
