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.

They share

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.

Testing, testing

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.

Schedule your vehicle to get the temperatures tested on your heating and air conditioning systems.

High end auto repair in West Seattle. Professional, white glove kind of service. Seem to know what they're doing. Shuttle available. The two times I've been there have been positive experiences. Not cheap, but not outrageous by any means.
Would recommend.

I started going to Tom's Automotive Service on the recommendation of a friend and I am so glad that I did! I found the staff to be professional, knowledgeable, friendly, courteous and accommodating. I stopped by to make an appointment, but needed to have oil added immediately which was done. I also had another problem which they handled promptly. Now they are helping me set up a schedule for servicing my car that should keep things running smoothly. I feel that my car is in good hands and I am very pleased.

Most of my contact has been with Bryce. He is very responsive, understands the need to avoid spending too much money on an older car. They stand by their work. Very trustworthy.
