Auto AC & Heating Tips

  • Run your AC system for at least 10 minutes per month even in winter to keep the seals lubricated
  • Replace your cabin air filter every 20,000-25,000 km for optimal airflow and air quality
  • If your AC stops blowing cold, get a leak test before just adding more refrigerant
  • A sweet antifreeze smell inside the cabin is a strong indicator of a leaking heater core
  • After winter, have your AC system inspected before the summer heat arrives
  • Don't ignore a defroster that doesn't work—it's a serious safety hazard in cold weather

Frequently Asked Questions

A basic AC recharge with leak inspection costs $150-$300. If a leak is found and a component needs replacement (condenser, evaporator, or compressor), the total repair can range from $500-$2,000+.

This is often caused by an intermittent refrigerant leak, a failing compressor clutch, or a blocked expansion valve. A professional leak test and system pressure check can pinpoint the exact cause.

Heater core replacement is labor-intensive because the dashboard must be partially or fully removed. Expect to pay $800-$1,800+ depending on your vehicle's complexity.

A properly sealed AC system should not need regular recharging. If it needs refrigerant frequently, there's an active leak that must be repaired first to avoid environmental damage and ongoing costs.
