a/c maintenance

With warmer weather around the corner, it’s time to start thinking about your vehicle’s air conditioning system.  There’s nothing worse than a long drive on a hot summer’s day without the A/C.  In this month’s blog post, we focus on A/C maintenance and repair.  We review the common problems and symptoms you may encounter, and ways to keep it properly maintained during scorching weather to keep you and your vehicle occupants cool.

How the A/C Works

Your vehicle’s A/C is very similar to the air conditioning you may have in your home.  The main components of the air conditioning system include:

  • Compressor: The heart of the system, the compressor, is driven by the engine. It pressurizes the refrigerant gas, transforming it into a high-pressure liquid.
  • Condenser: The hot, high-pressure liquid flows to the condenser, located in front of your vehicle. Air passing through the condenser cools the liquid, turning it into a low-pressure gas.
  • Evaporator: Inside the cabin, the evaporator absorbs heat from the air, cooling it down. The refrigerant changes from a liquid to a gas, releasing cool air.
  • Expansion Valve: This valve regulates refrigerant flow, maintaining the right pressure and temperature.
  • Blower Fan: The fan pushes cool air into the cabin.

Common A/C Problems and Symptoms

The air conditioning system can experience a variety of problems that cause it to fail, including:

  • Low Refrigerant: Leaks or insufficient refrigerant cause weak cooling. Look out for reduced airflow and lukewarm air.
  • Compressor Issues: A faulty compressor will not circulate refrigerant properly. Listen for strange noises or vibrations.
  • Clogged Condenser: Dirt buildup reduces efficiency. Check for poor cooling performance.
  • Faulty Evaporator: Mold growth or leaks can affect cooling. Musty smells or foggy windows indicate this issue.

A/C Repair and Maintenance

With summer soon upon us, it’s important to proactively inspect and maintain the A/C system.  Make sure to include the following in your repair and maintenance routine:

  • Regular Inspections: Have a professional check the A/C system annually to catch problems early.
  • Recharge Refrigerant: If cooling weakens, recharge refrigerant. Make sure there are no leaks before you have the refrigerant recharged.
  • Clean Condenser and Evaporator: Keep them debris-free for optimal performance. Dirt and debris can block the condenser from doing its job.
  • Replace Filters: Dirty filters reduce airflow. Replace them regularly.
  • Check Belts and Hoses: Cracked belts or hoses can lead to A/C failure.
