Can Storms Damage Your A/C Unit? Yes—Here’s What You Should Know

With storm season ramping up in Texas, it’s more important than ever to ensure your air conditioning system is protected. At Hal Watson Air Conditioning, we want to make sure your A/C unit—especially the outdoor condenser—is ready to handle whatever the weather throws at it.

While A/C systems are built to endure the elements, they’re not immune to storm-related damage. Here's what you should know to stay ahead of potential problems.

How Storms Can Damage Your A/C Unit

Hail

Hail is one of the most common threats to your outdoor unit during a storm:

• Damaged Coils and Fins – Hail can dent or bend the thin metal fins that help with heat exchange. When these are damaged, your system becomes less efficient and more likely to overheat.

• Refrigerant Leaks – A powerful impact can puncture coils, causing refrigerant to escape—leading to weaker cooling and potential compressor failure.

• Fan Damage – The condenser fan can be struck or jammed by debris, causing airflow issues or even complete system breakdown.

• Cosmetic Wear – Dents and scratches may not stop your unit from running right away, but they can compromise the protective casing and reduce longevity.

• Broken Seals – Cracks or broken seals can allow water and debris inside the unit, increasing the risk of rust and internal damage.

Thunderstorms

Thunderstorms bring more than just rain—they can impact your A/C in several serious ways:

• Lightning Strikes & Power Surges – A lightning strike (even nearby) can send a powerful electrical surge through your system, frying components like the compressor, capacitors, or circuit boards.

• Water Damage – If your system’s seals are already weakened, rainwater can seep in and cause electrical shorts or corrosion.

• Wind-Driven Debris – Twigs, leaves, and other debris can get lodged in your unit, clogging airflow and damaging moving parts.

• Flooding – Unlike rain, standing water or flood conditions can submerge electrical components. This kind of damage can be catastrophic and often requires replacement.
