Stay Cool All Summer: A/C Advice from the Experts

Aug. 18, 2025

With summer in full swing, both you and your vehicle might be feeling the heat. Whether you're commuting to work or cruising to the cottage, a well-functioning air conditioning (A/C) system can make every drive more comfortable and efficient. From clean air filters to smart cooling habits, these tips will help you beat the heat while keeping your vehicle running at its best.

How often should you change your cabin air filter?


Replacing your cabin air filter every 12 months or 16,000 km is one of the easiest ways to keep your vehicle’s air conditioning system running at its best. A clean filter not only helps your A/C work more efficiently, it also traps dust, pollen, and other pollutants so you and your passengers can breathe easier on every summer adventure.

Vent your vehicle before turning on the A/C


When you hop into a hot vehicle, resist the urge to crank the A/C right away. Instead, roll down the windows or open the doors for a minute to let the heat escape first. This will cool the cabin more efficiently and put less strain on your engine.

Keep your vehicle out of direct sunlight


Parking in the shade or using a windshield sunshade can make a big difference on hot days. By lowering the temperature inside your vehicle, you’ll reduce the strain on your A/C system when you start driving––helping it cool faster and maximize efficiency.

Book regular A/C Refresher service visits


Scheduling an A/C check-up every 12 months can help prevent more serious or widespread system issues that could lead to costly or inconvenient repairs. Talk to your Toyota University Trained Experts about when to book an appointment.

Not sure if it’s time for a checkup? Simply turn on your A/C and use this quick checklist to assess how your system is holding up, no tools required!

A/C Health Checklist

 
  • Unusual smells: Do you notice musty, sour, or stale odours when you turn on the A/C?
  • Uneven airflow: Does air seem weaker or inconsistent, even at high fan settings?
  • Strange noises: Are you hearing rattling, whirring, or hissing sounds?
  • Slow cooling: Is your cabin taking longer than expected to cool, even on a mild day?
  • Water leaks: Is water pooling inside the cabin after you use the A/C?
  • Weak cooling while idling: Does air feel cool while driving but warmer when idling?
  • Visible debris: Can you see dust, pollen, or particles around the air vents?
  • High humidity: Does your cabin feel humid, even when the A/C is on?
  • Overdue service: Has it been over 12 months or 16,000 km since your last A/C check-up?

If you answered "yes" to any of the above, now’s a great time to book an A/C refresher service.
