How Often Should You Service Your Furnace or AC in Toronto?
Toronto winters can be harsh, and the last thing you want is a furnace breakdown when temperatures drop below zero. On the flip side, summer heatwaves can test your air conditioner’s limits. That’s why regular HVAC maintenance isn’t just a nice-to-have—it’s essential for comfort, safety, and long-term savings.
At Grand Comfort Heating & Air Conditioning, we often get asked: “How often should I service my furnace or AC?”
Let’s break it down so you know exactly what to expect and when.
Why Regular HVAC Maintenance Matters
Your furnace and air conditioner are mechanical systems with dozens of moving parts. Over time, dust, wear, and small inefficiencies can build up, reducing performance and increasing energy costs.
Here’s why maintenance matters:
- Energy efficiency: A tuned-up system can operate up to 20% more efficiently.
- Longer lifespan: Regular service prevents wear that shortens equipment life.
- Fewer breakdowns: Minor issues can be fixed before they become expensive repairs.
- Better air quality: Cleaning filters and coils reduces dust, mold, and allergens.
- Safety: Technicians inspect for gas leaks, carbon monoxide risks, and wiring issues.
How Often Should You Service Your Furnace?
For Toronto homeowners, furnace service should be done once per year, ideally in early fall—before the cold weather fully sets in.
The best time is September or October, so your system is ready before the first freeze.
During a professional furnace tune-up, a technician will:
- Inspect and clean burners, heat exchangers, and blower motor
- Check gas pressure and CO levels
- Test ignition and flame sensors
- Lubricate moving parts
- Replace or clean filters
- Verify thermostat operation and safety controls
Even if your furnace “seems fine,” skipping annual service can lead to higher gas bills and unexpected mid-winter breakdowns.
How Often Should You Service Your Air Conditioner?
Your AC deserves the same attention—once per year, preferably in spring (April or May) before cooling season starts.
That way, it’s clean, efficient, and ready for summer demand.
During AC maintenance, the technician will:
- Clean the condenser coils and evaporator
- Check refrigerant pressure and temperature
- Inspect electrical connections
- Clear condensate drain lines
- Verify airflow and system performance
This not only keeps your home cooler but also extends the life of your compressor and prevents common issues like frozen coils or reduced cooling.
Seasonal Maintenance Tips for Toronto Homeowners
Between professional visits, a few small habits go a long way:
- Change filters every 1–3 months (especially during heavy use).
- Keep outdoor units clear of leaves, debris, and snow.
- Check vents and returns for obstructions.
- Use a programmable thermostat to balance comfort and efficiency.
- Listen for unusual noises—they’re early warning signs.
Toronto’s fluctuating climate puts extra stress on HVAC systems, so regular care is especially important here.
The Cost of Skipping Maintenance
A neglected furnace or AC might still work—but not efficiently. You’ll likely notice:
- Higher hydro or gas bills
- Uneven heating or cooling
- Poor air quality
- More frequent repairs
It’s like driving a car for years without an oil change—eventually, something breaks down.
