Why Your AC Keeps Tripping the Breaker – Causes & Fixes in Greater Toronto
If your AC keeps tripping the breaker, it’s more than just annoying—it’s a sign something is seriously wrong. In Toronto, Markham, and throughout the Greater Toronto Area (GTA), this problem is more common than you might think, especially during intense summer heatwaves when your system is under maximum stress.
At For Saving Home Services Inc., we’ve helped thousands of homeowners resolve this issue safely, quickly, and affordably. This article will walk you through the common causes, expected repair costs, and expert tips—so you’ll know when to call for air conditioner repair in Toronto or the GTA.
What It Means When Your AC Trips the Breaker
Your circuit breaker is designed to cut power when the electrical current exceeds safe levels. If it trips every time your air conditioner turns on, it means your AC is demanding more energy than the breaker can handle—or something is shorting the system.
Frequent trips can indicate:
Electrical short circuits
Overheating or failing components
Refrigerant issues
Aging or dirty parts causing overwork
It’s not just a nuisance—it’s a risk. Constant resets may damage your unit or cause fire hazards. If your air conditioner in Toronto or Markham keeps tripping your breaker, book a professional inspection immediately.
Why AC Units Trip Breakers in Toronto & Markham Homes
Older homes in Markham, North York, and central Toronto often have outdated panels or aging HVAC systems. Here are the most common reasons our techs see:
1. Clogged Air Filters & Blocked Airflow
Restricted airflow causes your AC to work harder, drawing more power until it trips.
Fix: Replace or clean filters every 1–3 months.
2. Dirty Outdoor Condenser Coils
Heat can’t dissipate efficiently, and the compressor overheats, tripping the breaker.
Fix: Have your outdoor coil cleaned yearly.
3. Failing Capacitor or Fan Motor
These parts require more startup energy when worn out, which trips the breaker.
Fix: Replace bad capacitors or motors quickly to avoid deeper system damage.
4. Low Refrigerant Levels
When refrigerant is low, your compressor overcompensates, pulling excessive power.
Fix: Check for leaks and recharge the system with the right refrigerant (avoid R22).
5. Short Circuits or Grounded Components
Loose wiring, corroded connections, or a grounded compressor can be dangerous.
Fix: Call a licensed technician for immediate electrical diagnostics.
How Breakers and AC Units Work Together
Air conditioners are high-demand appliances that require a dedicated circuit. When your system starts up, it sends a surge of electricity through the breaker. If the unit draws too much current—due to wear, dirt, or faults—the breaker trips to prevent overheating.
This isn’t a flaw; it’s protection. But if it keeps happening, something inside the system isn’t functioning correctly. That’s where our air conditioner repair Greater Toronto team comes in.

Should You Repair or Replace?
Use the $5,000 Rule:
If the age of your system × the cost of repair > $5,000, replacement may be smarter.
Example:
12-year-old AC × $600 = $7,200 → Replace
5-year-old AC × $300 = $1,500 → Repair
Energy Efficiency: Why Upgrading Might Save You More
If your unit is 10+ years old, it’s likely under SEER 13. Today’s high-efficiency systems exceed SEER 18, translating into 20–40% monthly energy savings.
Modern systems also support:
Smart thermostats
Zoned temperature control
Quieter performance
Eco-friendly refrigerants
With rebates and financing starting at $39/month, upgrading may cost less than ongoing repairs. Ask us about current rebate eligibility in Toronto and Ontario.
