What Causes an Air Conditioner to Freeze?

A frozen air conditioner is usually caused by restricted airflow, low refrigerant, or a dirty evaporator coil. When airflow is reduced or refrigerant levels become too low, the evaporator coil cannot absorb heat properly. Ice begins to form on the coil, reducing cooling performance and potentially damaging the compressor if the problem is ignored.

Our Air Conditioner Repair Port Coquitlam service identifies the exact cause of frozen coils by inspecting airflow, refrigerant charge, blower motor performance, static pressure, and evaporator coil condition before recommending repairs.

Ice on the coil is a symptom, not a repair. Read more about why an air conditioner freezes up before restarting a system that has developed frost or ice.

Why Is My Air Conditioner Running Constantly?

If your air conditioner runs for long periods without reaching the thermostat setting, several factors may be reducing system efficiency.

  • Dirty condenser coils.
  • Restricted airflow.
  • Incorrect refrigerant charge.
  • Poor insulation.
  • Improper load calculation.
  • Leaking ductwork.
  • High outdoor temperatures.
  • Thermostat calibration issues.

Professional Air Conditioning Repair Port Coquitlam restores proper cooling performance while reducing unnecessary energy consumption.

Long run times and frequent on-and-off cycles are not the same problem. If your system repeatedly starts and stops, see why an air conditioner may keep turning on and off and have the cause checked before compressor wear increases.

How Long Should a Central Air Conditioner Last?

A properly maintained central air conditioner typically lasts between 12 and 18 years. Equipment lifespan depends on maintenance history, operating conditions, installation quality, and annual usage.

Maintenance Condition Expected Performance
Annual professional maintenance Longer equipment lifespan.
Dirty condenser coils Reduced efficiency and increased compressor wear.
Restricted airflow Higher electricity consumption.
Routine inspections Fewer unexpected repairs.

SEER2 and High-Efficiency Cooling Systems

Today’s residential cooling systems are designed to meet updated SEER2 efficiency standards. Higher-efficiency systems use less electricity while delivering improved comfort, especially when combined with professional installation and regular maintenance.

Our technicians repair both older air conditioners and the latest variable-speed systems equipped with ECM blower motors, inverter compressors, smart thermostats, and advanced refrigerant metering devices.

Higher ratings can reduce operating costs, but only when the system is correctly sized, installed, and maintained. Our homeowner guide explains what SEER2 means for air conditioner efficiency.

Understanding R-410A and R-454B Refrigerants

Most existing residential air conditioners use R-410A refrigerant. Newer systems are gradually transitioning to R-454B, which has a lower Global Warming Potential (GWP) while maintaining excellent cooling performance.

Our technicians follow current manufacturer specifications when servicing refrigerant systems, ensuring safe handling and accurate charging procedures.

Equipment built for one refrigerant is not automatically interchangeable with another. Review R-410A versus R-454B to understand why refrigerant type matters when comparing repair and replacement options.

Indoor Air Quality and Cooling Performance

Your cooling system affects much more than temperature. Proper airflow, humidity control, filtration, and ventilation all contribute to healthier indoor air quality.

During many repair appointments we also inspect:

  • Air filters.
  • Blower assemblies.
  • Evaporator coils.
  • Humidity control.
  • Supply airflow.
  • Return airflow.
  • Ventilation performance.
  • Condensate drainage.

Seasonal HVAC Tips for Port Coquitlam Homeowners

Spring

Remove pollen, cottonwood, leaves, and debris from around the outdoor condenser before temperatures begin to rise.

Summer

Replace dirty air filters regularly, keep at least two feet of clearance around the outdoor unit, and schedule professional maintenance if cooling performance decreases.

Fall

Inspect the air conditioner after the cooling season and address small repairs before winter to prevent larger problems next year.

Winter

If your home uses a heat pump, keep snow, leaves, and debris away from the outdoor unit to maintain proper airflow.

DIY Maintenance vs Professional HVAC Repair
