5 Signs Your A/C System Needs a Tune-Up This Summer

There’s nothing quite like stepping into a cool, air-conditioned car on a hot summer day. But if your car’s A/C isn’t working like it used to, you could be in for an uncomfortable ride. At Bret’s Auto Repair, located in Lynnwood, we see a spike in A/C service visits every summer — and for good reason. Your A/C system works hard during the warmer months, and without proper care, it can wear out or fail altogether.

Here are five common signs that your vehicle’s air conditioning system might need a tune-up:

1. Weak or Warm Airflow

If your vents are blowing warm or weak air even with the A/C turned on high, something’s not right. This could be due to low refrigerant, a failing compressor, or a clogged cabin air filter.

Expert Tip: Don’t wait until it completely stops working. Early diagnosis at our local auto shop can save you money and stress.

2. Unusual Noises When the A/C Is On

A/C systems should run quietly. If you hear rattling, grinding, or squealing noises when the system is operating, it could mean there’s a loose belt, a failing compressor, or debris in the blower motor.

What to do: Stop by Bret’s Auto Repair and we’ll get to the root of the problem.

3. Strange Odors Coming from Vents

A musty or sour smell could be a sign of mold or bacteria buildup, especially after the wet spring season in the Pacific Northwest. Mold spores love to grow in dark, wet spaces.

Solution: Brets Auto Repair can perform an extensive 3-step  mold & mildew eradication service  to kill those musty spores on contact by accessing the inside of the heater box where they thrive. We will inject a foaming agent to kill the spores and then clear all duct work of living organisms. Finally, we will ensure your cabin filter is clean and deodorized.

4. Moisture or Leaking Inside the Cabin

Notice water pooling on your floor mats? This may be due to a clogged or leaking A/C drain tube.

We can help: Come into Bret’s Auto Repair in Lynnwood for a quick inspection to prevent interior damage.

5. It Takes Too Long to Cool Down

If your car used to cool down in minutes but now struggles to keep up, low refrigerant or worn components could be to blame.

Get it checked: Our certified techs will diagnose and fix the issue fast.
