How to Maintenance Your Car’s HVAC System

Keep Yourself Cool in and Out of the House

car HVAC maintenanceAs a homeowner, you probably know how to perform routine maintenance on your home HVAC system in order to keep it running smoothly, but do you know how to maintenance your car’s HVAC system? After all, it does keep you warm in the winter and cool in the summer while you drive. Here are some tips from our HVAC service company:

Coolant/Water Level

  • You should check your coolant/water mixture level on a regular basis. Refer to your owner’s manual to find out how often this should be checked.
  • When adding coolant, always refer to the bottle to see how much water it needs to be mixed with.
  • Use the type of coolant that your owner’s manual recommends. A lower-grade coolant may not be able to optimally heat or cool your car.

Radiator Flushing

  • You should also flush your radiator on a regular basis. Again, refer to your owner’s manual to find out how often.
  • In most cases, you simply have to open the valve below your radiator to empty the remaining coolant into a container. Then, close the valve, add water, and run your engine for a few minutes before adding the new coolant (again, refer to your manual for specific instructions).

Radiator Hoses

  • Check your radiator hoses frequently for signs of damage or wear. Depending on the amount the hose(s) is worn, you can buy a hose patch kit. If the damage is severe, you may have to replace your hose.

Thermostat Problems

If you’re having problems with your thermostat, refer to your owner’s manual to see where it is located. If you can easily access it, there is a way to test it:

  • Take the thermostat out of its housing and place it in a cup of (very) hot water. If the aperture on your thermostat stays closed, you’re in need of a new thermostat; when the engine heats up, your thermostat aperture should open.

Clearing/Cleaning Vents

  • Check your vents for clogs and debris and vacuum them to clear them out. Clogged vents mean less hot or cold air that reaches the inside of your car. They can also make your HVAC system work harder.
