Key Signs Your AC System Needs Repair

Recognizing Common AC Issues

Common A/C Problems

  • Warm Air From Vents – If your AC blows warm air, it usually means low refrigerant or a leak. This prevents the system from cooling efficiently and needs quick inspection.


  • Strange or Loud Noises – Banging, rattling, or buzzing often point to loose parts or failing electrical components. These noises won’t go away on their own and can cause bigger damage.


  • Water Leaks Around the Unit – Pooling water or a dripping AC typically means a clogged condensate drain. Left unchecked, it can lead to water damage inside your Toronto home.

Issues That Need Repair

  • Electrical Failures – Short circuits, burnt smells, or sudden shutdowns are signs of dangerous electrical problems. These require immediate service from certified technicians.


  • Dirty or Blocked Coils – When coils are clogged, airflow drops and your AC strains to cool your home. This leads to higher energy bills and unnecessary wear on the system.


  • Refrigerant Troubles – Low or leaking refrigerant causes weak cooling and ice buildup on the lines. Long-term neglect can damage the compressor and lead to costly repairs and leaving you without cool air.

A/C Performance Issues

  • Weak Airflow From Vents – Poor airflow often points to blocked ducts, a failing blower motor, or a dirty filter. This makes your AC work harder and reduces comfort in your Toronto home.


  • Inconsistent Cooling Between Rooms – Hot and cold spots commonly come from thermostat issues or duct imbalances. These problems can keep your system running longer than necessary.


  • System Running Constantly – If your AC never shuts off, it could be due to airflow restrictions or internal component issues that require immediate attention.

Comprehensive Air Conditioning Repair Process

What Happens During A Service Call

When you schedule an air conditioning repair, our licensed technicians begin with a full inspection of your system, checking components like coils, drain lines, and refrigerant levels. This allows us to identify issues such as clogged lines, dirty coils, or potential leaks. Once the inspection is complete, we diagnose the exact cause of your AC problem, whether it’s a faulty thermostat, refrigerant issue, or malfunctioning evaporator coil.


After diagnosis, we repair or replace the necessary components to restore proper cooling. You’ll receive upfront pricing and clear recommendations so you can make informed decisions with no surprises.

Most Common Questions About AC System Repairs

Why is the airflow from my air conditioning system weak?

Weak airflow usually comes from clogged filters, blocked ducts, or a failing blower motor inside your air conditioning system. These issues restrict circulation through the cooling system, causing poor home comfort and higher energy use.

A refrigerant leak often leads to warm air from vents, hissing sounds, or ice forming on the AC unit. Leaks reduce cooling power and should be repaired immediately to protect the compressor.

When does my cooling system need air conditioning repair services?

If your cooling system makes unusual noises, struggles to cool your home, or cycles nonstop, it’s time to call for air conditioning repair services. Early repairs prevent bigger problems and control long-term repair costs.

Key Signs Your AC System Needs Repair

Recognizing Common AC Issues

Common A/C Problems

  • Faulty Ignition System – A worn ignitor or pilot light can stop

    Your furnace from producing heat, leaving your home cold.


  • Dirty Flame Sensor – When covered in dust or soot, the sensor

    can’t detect the flame, so the burner automatically shuts off.


  • Thermostat Malfunction – Incorrect settings or wiring issues can

    prevent your system from communicating properly, reducing efficiency and airflow.


Issues That Need Repair

  • Banging or Rattling Sounds – Loose parts, a cracked heat

    Exchanger or blower motor issues can cause loud, disruptive noises.


  • Burning or Electrical Odour – Dust or wiring problems can produce

    burning smells when your furnace cycles on.


  • Rotten Egg Smell – A sulphur odour may indicate a gas leak

    and needs immediate emergency furnace repair for safety.

    Turn off your systems and call Real Deal HVAC immediately.
