HVAC systems don’t require a ton of maintenance, but like all systems, they will need a little love. Most maintenance tasks are inexpensive and don’t require any tools. However, some tasks will require more effort and specialized tools, and so are likely best left to your local shop.

Here’s a list of HVAC maintenance tasks that should ideally be performed. In the real world, of course, many of these aren’t. I’ve broken this list into easy DIY tasks and those that will require tools:

Easy DIY tasks

  • Remove tree fall from the windshield cowl drain – turn of every season
  • Replace cabin filter – annually
  • Check and clear airconditioning drain – annually
  • Add anit bacterial spray to the HVAC vents – annually

Require tools

  • Replace aircon refrigerant and add fresh lube – every three years
  • Backflush coolant system – every four years
  • Replace coolant system thermostat – every four years
  • Replace coolant system waterpump – every four years

If you tackle coolant system maintenance yourself, you may find the tools on the Coolant system maintenance page helpful.

Here I’ve listed a few products to help keep your vehicle’s HVAC system working at its best.
