What’s the average lifespan of a furnace?

Most furnaces last between 15 to 20 years with proper maintenance. Factors like usage, maintenance frequency, and the quality of the original installation can all impact lifespans. If your furnace is over 15 years old and experiencing frequent issues, it may be time to consider a replacement.

How much does a furnace inspection cost?

Furnace inspection costs can vary depending on the depth of the inspection and whether it’s part of a maintenance package. At Black Forest Heating, we offer competitive pricing and seasonal promotions. A thorough inspection includes checking the heat exchanger, burners, blower motor, thermostat, and safety controls.

How often should a furnace be serviced?

We recommend annual furnace maintenance, ideally in the fall before the heating season begins. Regular servicing helps improve efficiency, extend the life of your system, and catch small issues before they become costly repairs.

When should you replace your furnace?

You should consider replacing your furnace if: • It’s over 15–20 years old • Your energy bills are rising despite regular maintenance • Repairs are becoming more frequent and expensive • Your home has uneven heating or comfort issues • The furnace is making unusual noises or emitting strange odors

Should I repair or replace my furnace?

If your furnace is relatively new and the repair is minor, fixing it is usually the best option. However, if your system is aging and the repair cost is significant (typically more than 50% of the cost of a new unit), replacement may be more cost-effective in the long run. Our technicians can help you weigh the pros and cons based on your specific situation.

Common Furnace Problems We Repair

We service both gas and electric furnaces, and our technicians are equipped to handle everything from minor fixes to complex repairs. Here are some common furnace issues we can fix:

No heat or insufficient heating. This could be caused by a malfunctioning thermostat, a clogged air filter, ignition system failure, or issues with the gas supply. We’ll pinpoint the cause and restore your heat quickly.
Frequent cycling (Turning on and off too often). If your furnace cycles too frequently, it may be due to a dirty filter, thermostat miscalibration, or blocked airflow. This not only affects comfort but also increases wear and tear.
Unusual noises. Rattling, banging, or squealing sounds can signal problems with the blower motor, loose components, or a worn-out belt. We’ll inspect and repair the source of the noise to prevent further damage.
Pilot light or ignition problems. A pilot light that won’t stay lit may be caused by a faulty thermocouple or dirty components. Our technicians can clean or replace parts to ensure reliable ignition.
Blower not running or running continuously. This may indicate a faulty limit switch, motor issues, or electrical problems. We’ll troubleshoot and repair the system to restore normal operation.
Poor airflow. Weak airflow can result from duct obstructions, blower motor issues, or dirty filters. We’ll assess your system and improve its efficiency.
Burning smell or strange odours. These could be signs of overheating, electrical issues, or accumulated dust. We’ll investigate and eliminate any hazards.

Remember, gas furnace issues can be dangerous, so call Black Forest Heating for repairs to ensure safety and efficiency.

Choosing the Right Furnace for Your Home

Many factors are at play when buying a new electric or gas furnace:

Comfort features. A single-stage furnace has basic on or off options. A two-stage furnace offers more control with high- and low-stage options, providing more consistent comfort. A modulating furnace offers the most precise temperature control.
Humidity control. Humidity plays a vital role indoor air quality. You can partner your furnace with a whole-home humidifier to optimize humidity levels, so you feel warmer at cooler temperatures.
Noise levels. If your furnace space is near a living area, consider one with an insulated cabinet to reduce noise. Moreover, two-stage and modulating units run more quietly than single-stage units.
Energy efficiency. A furnace with the EnergyStar label uses between six and nine per cent less energy than other standard models. Home heating accounts for 61 per cent of your energy costs, so reducing your energy use with a high-efficiency furnace can save money in the long term.

5 Signs It's Time to Replace or Upgrade Your Furnace

Is it time for a furnace upgrade in your home? Here are a few questions to consider.

Is your furnace more than 18 years old? If so, it’s probably nearing the end of its life span.
Has your furnace been acting up more often lately? Furnace repairs are a fact of life, but if you’re dealing with costly repairs every few months, it may be worth investing in a new model.
Are your energy bills mounting year after year? Your furnace may be working harder to deliver the same amount of heat, and you might benefit from a new energy-efficient model.
Are certain rooms cooler than others? It means your furnace is running inefficiently.
Has your furnace gotten too noisy? Consider replacing it with a two-stage or modulating model.

Furnace FAQ

The cost of a new furnace in Ontario can vary widely depending on the size of your home, the type of furnace (gas, electric, or high-efficiency models), and the complexity of the installation. Additional factors like ductwork modifications or smart thermostat upgrades can also affect the final price. For an accurate estimate, we recommend scheduling a free in-home consultation with one of our HVAC specialists.

Furnace size is typically measured in BTUs (British Thermal Units), and the right size depends on your home’s square footage, insulation, ceiling height, and even the number of windows. An undersized furnace won’t heat your home effectively, while an oversized one can lead to inefficiency and wear. Our technicians can perform a detailed load calculation to determine the ideal furnace size for your space.
