When your car’s A/C is working right, it’s easy to take it for granted. But on an older vehicle, that nice cold air depends on a system that’s been under the hood for a long time — and over the years, seals dry out, refrigerant leaks off, and components like the compressor or blower motor can start to wear.
Regular A/C service isn’t just about comfort (though it is nice to stay cool on a hot day). If your air isn’t as cold as it used to be, or it takes a while to kick in, that’s a sign it’s time for a checkup — and often, it’s something simple like low refrigerant or a clogged cabin air filter.
Catching issues early can keep repair costs down. A small leak now is a lot easier to deal with than a burned-out compressor later. And even if you don’t use the A/C much, running it every so often helps keep seals and components in good shape.
A well-serviced A/C system makes driving your older car a whole lot more enjoyable — and keeps things from getting sticky when summer rolls around.
Air isn’t as cold as it used to be, or never gets cold at all
Takes a long time to cool down after turning on the A/C
Weak airflow from the vents, even on high settings
Strange smells when the A/C is running (musty, moldy, or sour odors)
Unusual noises — like clicking, hissing, or rattling when A/C is on
A/C only works while driving, but not when idling
Water leaking into the cabin — may be a clogged drain line
Compressor doesn’t kick on, or cycles on and off rapidly
Foggy windows that won’t clear — especially when defrost is set to A/C
Dashboard A/C light blinks or doesn’t stay on
Visible refrigerant leak under the hood or near A/C lines (usually oily residue)
A/C systems can fade slowly, so it’s easy not to notice until it’s hot out and not working. A quick checkup now can keep you cool and comfortable when you need it most.
