Keeping Your Car A/C Running in Houston Summer Heat

5 min read

In Houston, a working air conditioner isn't a luxury — it's a necessity. When temperatures hit 100°F and humidity is through the roof, a failing A/C can make driving dangerous, especially for children and elderly passengers.

Here's what to check before the hottest months arrive:

Refrigerant level: Low refrigerant is the most common cause of weak A/C. Over time, refrigerant can leak through small cracks in hoses or fittings. If your A/C isn't as cold as it used to be, a recharge may be all you need.

Compressor condition: The compressor is the heart of your A/C system. If you hear a clicking or grinding noise when the A/C is on, the compressor may be failing.

Cabin air filter: A clogged cabin air filter restricts airflow and reduces A/C effectiveness. Most manufacturers recommend replacing it every 15,000–25,000 miles.

Condenser: The condenser sits in front of your radiator and can get clogged with debris. A blocked condenser reduces cooling efficiency significantly.

Evaporator: If your A/C smells musty, the evaporator may have mold or bacteria growth. This is common in humid climates like Houston.
