Neighboring Systems in Your Vehicle: Air Conditioning & Heating
These two systems actually share the same “home” under the hood, but they are very different systems. Literally, the difference between “hot & cold”.
Kind of like two different families who live next to each other in a duplex-type of property. They are connected in housing, but different in operation and function.
The air conditioning and the heating systems share the vent system in your vehicle, similar to the way your air conditioner and your heater share the vent system in your home.
When you bring your vehicle in for servicing, we test how well each system is operating. We use a temperature probe at the vents to measure how hot the heater runs and how cool the air conditioner blows.
We also test the temperatures during a road test with all of our services, from oil changes to some of the bigger service inspections (like 30k or 60k appointments).
In the winter we do test the air conditioning because it enhances the defroster’s effectiveness by drying the damp air in the passenger cabin.
Spring and Fall are great times to have both heating and air conditioning system temperatures tested.
