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.

I take my car to Tom's because they are friendly and reliable. I appreciate they are able to "triage" and explain the maintenance needed to keep my car up and running. It's great they offer a shuttle in the morning and late afternoon to help the locals get back to work!
I once had to pull off the freeway due to my car acting oddly. I called Kandie at Tom's and she was able to explain what I needed to do. This helped me stay calm and confident in an otherwise stressful situation.

Tom’s is great. I took my vehicle in for a transmission issue. They were thorough with their diagnostic and communicated my options every step of the way. Honest and reliable service.

Everyone at Tom's cares about delivering great, expert service and keeping your car or truck in excellent mechanical condition. I have a 2001 Yukon XL which is a 3/4 ton towing vehicle and has been serviced at Tom's for 14 years. It has 187,000 miles on it, and I credit their commitment to excellent service and workmanship for the vehicle's longevity. They are the best in the business, and we are super fortunate to have them in West Seattle.

Tom's Automotive is open and honest. They have a friendly staff and are helpful in getting answers that work for the budget. I never feel pressured to do something that I don't want to do and they are willing to present options. Thanks, Tom's!
