AC blowing warm air

When your AC isn’t cooling, it could signal issues with the compressor, refrigerant, or airflow.

Unusual noises or odors

Strange sounds or smells often point to mechanical problems or mold growth inside your unit.

Poor airflow

Weak airflow may indicate clogged filters, duct obstructions, or a failing blower motor.

Refrigerant leaks

Leaking refrigerant reduces cooling efficiency and can damage your AC over time.

Frozen evaporator coils

Ice on coils usually means restricted airflow or low refrigerant levels.

Tripped breakers or electrical faults

Electrical problems can shut down your AC or signal deeper system failures.

Water Leaks

Water Leaks from the system often caused by evaporator coil, poor insulation or coughed drain.

7 Common Air Conditioner Problems We Fix:

From weak airflow to electrical faults, we quickly diagnose and fix the most common AC issues to keep your home cool and comfortable.

DIY

What to Try Before Calling:

1. Thermostat Cooling Setting

Verify your thermostat is switched to "cool" mode and set lower than current room temperature to activate the AC system.

2. Air Filter Maintenance

Dirty filters block airflow. Replace disposable filters monthly or clean reusable ones to improve efficiency and air quality.

3. Circuit Breaker Check

Inspect your electrical panel for tripped breakers. Reset any switched-off HVAC breakers to restore power.

4. Condenser Unit Clearance

Remove leaves, grass, or debris within 2 feet of the outdoor unit to ensure proper airflow and prevent overheating.

5. Thermostat Batteries

Weak batteries cause thermostat malfunctions. Replace batteries annually or when the display dims/flickers.

6. Professional HVAC Help

If problems continue after basic checks, contact our certified Mississauga technicians for expert diagnosis and repair.
