Benefits of an Energy-Efficient Furnace

Gas furnaces have come a long way when it comes to efficiency.
Investing in a new, highly energy-efficient furnace has a few advantages. Energy efficiency is measured by the Annual Fuel Utilization Efficiency (AFUE) rating. The higher the rating, the more fuel is converted into heat. Using less fuel means less emissions and lower energy bills for you.
Modern high efficiency furnaces are much quieter and have more even heating throughout your home as well.
With long-term savings on energy costs, durability, and reliable warmth even in Canadian winters, upgrading to an energy-efficient furnace can make a lot of sense for homeowners looking to save on heating costs and reduce their carbon footprint.
Does Your Furnace Need Repair?
Wondering if your furnace needs a repair? Here are a few signs to look out for:
- Inconsistent heating: If some rooms are warmer than others, or if your furnace runs constantly and never gets to the temperature you’ve set, there could be an issue with your vent airflow or the thermostat itself.
- Unusual noises: Hear banging, rattling, or squealing? These could be loose belts, worn-out bearings, or cracks in the heat exchanger.
- Spike in your energy bill: Your furnace could be working overtime and struggling to keep up because of some internal issue.
- Weird smells: Your furnace may have a clogged filter or an issue with the combustion process.
- Short cycling (frequent on/off cycles): Furnace short cycling is when your furnace turns on and off constantly, without fully heating your home. This can happen when your furnace overheats, the thermostat isn’t working right, or the air filter is clogged.
Have you checked your thermostat? Make sure it’s on and set to the right temperature. A quick adjustment or battery replacement may fix the problem.
Is your filter dirty? A clogged furnace filter restricts airflow, causing your furnace to work harder and potentially overheat.
Common Furnace FAQs
When Do I Need Furnace Replacement?
If your furnace is getting towards the end of its life (around 15 years), is starting to need more frequent repairs, or is no longer keeping your home warm, it’s probably time to invest in a replacement.
How Long Do Furnaces Last?
Most gas furnaces will last around 15-20 years. Regularly changing the filter and having regular maintenance and inspections will help a furnace last longer and keep it heating more efficiently.
How To Tell The Age Of My Furnace?
Your furnace should have a data plate inside the cabinet that will say the year it was made. If yours doesn’t, call the manufacturer, give them the serial number and ask them what year it’s from.
Why Is My Furnace Blowing Cold Air?
Leaving your thermostat set to “on” instead of “auto” can cause the fan to blow air even when the furnace isn’t heating it. A clogged air filter can restrict airflow, which can cause the furnace to overheat and shut off the burner, which will also leave you with cold air blowing from vents. Issues with a malfunctioning pilot light or ignition system can sometimes stop a furnace from heating air. And in some cases, a gas supply that isn’t working or a broken heating element can also be the cause.
Why Is My Furnace Leaking Water?
This is usually caused by condensation. High-efficiency furnaces produce condensation which drains through a condensate line. If this line gets clogged, water can back up and leak around the furnace. It could also be a broken or blocked condensate pump, which moves water out of the furnace. In standard-efficiency furnaces, leaks can happen when there’s an issue with the humidifier connected to the furnace.
Why Does My Furnace Keep Shutting Off?
A clogged air filter is usually the reason. When the filter is dirty, it restricts airflow, causing the furnace to overheat and shut down as a safety measure. Other possible causes can be a malfunctioning thermostat telling the furnace to turn off if it’s misreading the room temperature. And faulty flame sensors or dirty burners can also cause your gas furnace to shut off.
How Often Should I Clean My Furnace?
We recommend that you have your gas furnace cleaned annually to prevent breakdowns. An annual cleaning will improve your furnace’s performance, lower your energy bills, and help your furnace last for years.
