A Proud Canadian HVAC Company
Every winter, Toronto homeowners rely on their furnaces to stay warm and comfortable — but a few common mistakes can make your system work harder than it should. From skipped maintenance to blocked vents, these habits can lead to higher bills, uneven heating, and unexpected repairs.
Let’s look at the five most common furnace mistakes homeowners make every winter — and how you can easily avoid them.
Regular maintenance keeps your furnace running efficiently and extends its lifespan.
Blocking or closing vents disrupts airflow and can strain your heating system.
Replacing your furnace filter on time prevents costly breakdowns.
Paying attention to early warning signs can save you from expensive repairs.
Upgrading to a high-efficiency system can reduce your energy bills and carbon footprint.
When the temperature drops across Toronto and the GTA, your furnace becomes one of the most important systems in your home. But even the most reliable heating equipment can run into trouble if it’s not used or maintained properly.
The good news? Most furnace problems are completely preventable. At Econoair, we’ve serviced thousands of homes and noticed that the same mistakes pop up every year — small oversights that can cost homeowners hundreds of dollars in wasted energy, shorten the lifespan of their systems, or lead to a full breakdown in the middle of winter.
By learning what these mistakes are (and how to fix them), you can keep your furnace running efficiently, improve your indoor air quality, and protect your investment for years to come. Here are the top five furnace mistakes Toronto homeowners make — and what you can do differently this winter.
One of the biggest mistakes homeowners make is waiting until their furnace stops working to call for help. While it might seem like a good way to save money, skipping annual maintenance almost always leads to higher costs later on.
Your furnace is a mechanical system — it collects dust, experiences wear, and needs adjustments to stay efficient. Without yearly maintenance, small issues such as loose wiring, dirty burners, or worn belts can escalate into major repairs. Over time, your system can lose 5% of its efficiency each year, which means higher energy bills and uneven heating throughout your home.
During a professional furnace tune-up, Econoair’s licensed technicians perform a full inspection and cleaning. They check safety controls, gas pressure, electrical connections, and airflow, ensuring everything runs at peak performance. Routine maintenance also helps detect carbon monoxide leaks early, keeping your home safe.

It’s a common misconception that closing vents in unused rooms saves energy. Unfortunately, this often does the opposite. Your furnace is designed to distribute air evenly throughout your duct system. When vents are closed or blocked by furniture, rugs, or drapes, it increases air pressure in the ducts and forces your furnace to work harder.
That extra strain can cause the heat exchanger to overheat, potentially leading to cracks or early system failure. It can also create cold spots in your home and make your thermostat work overtime — driving up energy costs.
The same applies to blocked return vents. When return airflow is restricted, your furnace can’t circulate air properly, reducing efficiency and indoor comfort.
Tip: Keep all vents open and unobstructed, even in rooms you don’t use often. If you’re still experiencing uneven heating, Econoair can inspect your ducts and recommend solutions such as zoning systems or airflow balancing to improve comfort and performance.
A dirty or incorrect filter is one of the most overlooked causes of furnace issues. Your furnace filter’s job is to trap dust, pet hair, and other airborne particles, keeping your air clean and protecting internal components from damage. But when the filter is clogged or the wrong size, it restricts airflow — forcing your system to work much harder than necessary.
Restricted airflow can cause overheating, reduced efficiency, and even system shutdowns. In severe cases, a neglected filter can lead to cracked heat exchangers or blower motor failure. Beyond performance, dirty filters worsen indoor air quality, triggering allergies or respiratory irritation.
Most manufacturers recommend replacing your filter every 1–3 months, depending on your household’s needs. Homes with pets, smokers, or allergy sufferers may need to replace filters more frequently.
Tip: During your next service visit, ask your Econoair technician which filter size and MERV rating best suits your furnace model. Using the correct filter ensures proper airflow, lower energy bills, and cleaner indoor air.
Your furnace often gives small warning signs before a major failure. Unusual noises like banging, rattling, or whistling could signal loose components or airflow issues. Short cycling — when your furnace turns on and off frequently — may indicate a clogged filter, bad thermostat, or overheating. If you notice inconsistent temperatures or cold spots, that could point to duct leaks or weak airflow.
Ignoring these signs can turn a minor fix into a costly emergency. For example, a loose blower belt might cost less than $100 to replace, but if left unattended, it can damage the motor or fan assembly — a repair that runs several hundred dollars.
Econoair’s technicians are trained to identify and repair these issues quickly. We offer same-day furnace repair service in Toronto and the GTA, so you’re never left in the cold.
Tip: If your furnace starts acting up — strange sounds, burning smells, or uneven heating — don’t wait. Early diagnosis saves you time, money, and stress.
Even with perfect maintenance, no furnace lasts forever. Older systems (typically 15 years or more) can lose significant efficiency compared to newer, high-performance models. Modern heat pumps and high-efficiency gas furnaces are designed to use less energy while providing the same, if not better, comfort.
Upgrading your furnace is not just about replacing old equipment — it’s about improving your home’s overall efficiency and reducing monthly bills. With Toronto’s rising energy costs, an upgrade could save you hundreds every year. Plus, today’s systems are quieter, more reliable, and better for the environment.
At Econoair, we help homeowners choose the right system for their home size, insulation, and budget. We provide honest advice, professional installation, and full transparency on available rebates. Right now, you can save up to $1,500 off a new installation when you upgrade through Econoair — making it easier than ever to invest in long-term comfort.

Uneven heating is a common problem in Toronto homes, usually caused by blocked vents, leaky ducts, or dirty air filters. When airflow is restricted, your furnace has to work harder to push warm air through your home, leading to cold spots and inconsistent comfort. Closed vents, furniture blocking registers, or improper duct balancing can also create uneven temperatures.
Our Econoair technicians perform full airflow diagnostics to pinpoint the issue — from duct leaks to uneven distribution — and provide tailored solutions to restore even heating throughout your home. If your furnace ever stops heating completely, our 24/7 emergency team is only a call away. We’ve earned the trust of over 20,000 Toronto homeowners by delivering fast, honest, and professional HVAC service every time.
Failing to replace your furnace filter is one of the easiest ways to shorten your system’s lifespan. A clogged filter restricts airflow, forcing your furnace to overwork — which increases your energy bills, reduces heating efficiency, and can even cause system shutdowns. Dirty filters also circulate dust and allergens, worsening your home’s air quality.
At Econoair, we recommend checking your furnace filter every 1–3 months and replacing it whenever it looks dirty. Our expert technicians can show you how to choose the right filter size and MERV rating for your system to maintain peak performance.
If your furnace stops working due to a blocked filter or any other issue, you can rely on our 24/7 emergency repair services anywhere in the GTA. With over 20,000 happy customers, we’re proud to be Toronto’s most trusted HVAC specialists for maintenance, repair, and installation.
The easiest way to know if it’s time for a furnace replacement is to look at age, performance, and repair frequency. If your furnace is more than 15 years old, requires frequent repairs, or can’t maintain consistent heat, upgrading may save you more in the long run. Signs like strange noises, short cycling, or rising energy bills often mean your system is wearing out.
Econoair’s trusted HVAC professionals offer honest assessments — we’ll never push a replacement if a repair will do the job. But when it’s time for an upgrade, we provide high-efficiency furnaces and heat pumps designed to save you money while keeping your home cozy.

Yes — closing vents can cause air pressure buildup in your duct system, forcing your furnace to work harder and run hotter than intended. Over time, this added strain can crack your heat exchanger, damage the blower motor, and lead to costly repairs. Many homeowners close vents to save energy, but it often does the opposite by increasing wear and reducing efficiency.
To prevent this, make sure all supply and return vents stay open and unobstructed by furniture or rugs. If you still experience uneven heating, Econoair can balance your airflow or recommend a zoning system to improve efficiency.
And remember — if your furnace ever overheats or shuts down unexpectedly, our 24/7 emergency service is available throughout Toronto. With over 20,000 satisfied customers, Econoair is Toronto’s most trusted HVAC company, committed to keeping your home warm, safe, and efficient.
