What Should I Do If My HVAC Is Leaking Water or Refrigerant in Toronto, OH?

Quick Answer

If your HVAC is leaking water or refrigerant, turn the system off and call a licensed HVAC professional.

Water leaks usually point to drainage or airflow issues, while refrigerant leaks indicate a sealed-system failure that should not be run.

Do not keep running the system or add refrigerant—both can cause major system damage.

Why HVAC Leaks Are a Serious Problem in Toronto Homes

Toronto’s housing mix creates specific risks when HVAC leaks occur, especially in neighborhoods closer to the river and older developments uphill.

Many homes here were built between the 1920s and 1970s, often with:

• Full basements, some partially finished
• Older floor drains tied into aging sewer lines
• HVAC systems upgraded long after original construction
• Drainage lines routed long distances to reach exterior discharge

In Toronto, HVAC leaks often show up as basement moisture before homeowners realize the system is involved.

We regularly see leaks misdiagnosed as foundation seepage or plumbing issues when the real cause is HVAC drainage or airflow failure.

Water Leak vs. Refrigerant Leak: What’s the Difference?

If Your HVAC Is Leaking Water

Water leaks in Toronto homes are commonly caused by:

• A clogged or deteriorated condensate drain
• A rusted or cracked drain pan
• A frozen evaporator coil that thawed
• Airflow restrictions from older duct systems

These problems are usually repairable if addressed early.

If ignored, water leaks can damage basement walls, flooring, and HVAC equipment.

If Your HVAC Is Leaking Refrigerant

Refrigerant leaks are more serious.

• Refrigerant remains sealed inside the system
• It does not get “used up”
• Any loss means there is a leak

Operating the system with low refrigerant strains the compressor and can turn a repair into a system replacement.

Refrigerant leaks require EPA-certified diagnosis and repair.

Should I Turn Off My HVAC If It’s Leaking?

Yes—always turn the system off.

Running a leaking system can:

• Flood basements
• Freeze evaporator coils
• Damage electrical components
• Permanently harm the compressor

Turning the system off limits damage and controls repair costs.

What You Should Do Right Away

Step 1: Shut the System Off

Use the thermostat or service switch. Avoid running it “until it stops.”

Step 2: Look for Visible Water

Check:

• Around the furnace or air handler
• Condensate drain connections
• Nearby floor drains or low points

This helps determine whether the issue is drainage-related or a sealed-system problem.

Step 3: Call a Licensed HVAC Company

Drainage routing and refrigerant repairs require proper tools, training, and safety controls. Temporary fixes usually fail.

A Real Toronto Example

We recently helped a homeowner near North Fourth Street in a 1940s two-story home with a full basement.

They noticed recurring water near the floor drain and assumed it was sewer-related. The actual problem was a condensate line tied into an aging drain that backed up during high humidity, causing overflow near the furnace.

Unique Toronto cost driver: older shared drain lines often restrict flow under heavy moisture loads. Once the drain was rerouted correctly, the leak stopped and the basement stayed dry.

Cost: What Typically Affects Repair Pricing

HVAC leak repair costs depend on cause, access, and system condition.

What Drives Cost Higher

• Refrigerant leaks in evaporator coils or line sets
• Compressor damage from continued low-charge operation
• Drain lines buried behind finished basement walls
• Older systems using discontinued refrigerants

What Keeps Cost Lower

• Early diagnosis
• Simple drain clearing or rerouting
• Minor pan or safety switch replacement

Some leaks are service-level repairs, while others point toward replacement-level decisions.

Common Mistakes Toronto Homeowners Make

The most common mistake: assuming basement water is a plumbing or foundation issue.

In Toronto, that delay often leads to:

• Rusted HVAC components
• Electrical failures
• Mold growth inside ductwork

Another frequent mistake is adding refrigerant without repairing the leak, which increases long-term costs and shortens system life.

Neighborhood-Specific Issues That Cause HVAC Leaks

Local construction patterns matter:

• Basements: gravity drains clog or back up
• Older sewer connections: limit drainage capacity
• Electrical limitations: restrict modern safety upgrades
• Retrofit ductwork: airflow restrictions freeze coils

Frequently Asked Questions About HVAC Leaks

Can I Clean the Drain Line Myself?

Minor surface clogs can sometimes be cleared, but deeper blockages often require professional tools. Improper cleaning can cause hidden leaks.

Does a Refrigerant Leak Mean I Need a New System?

Not always. System age, refrigerant type, leak location, and overall condition all factor into the decision.
