How Frogs Can Short-Circuit Your Air Conditioner

August 25, 2025

In Gold Coast, air conditioning is essential, but did you know even a small frog can bring your entire system to a stop? When a frog can short-circuit an air conditioner, the damage isn’t just surprising, it’s expensive. From fried circuit boards to costly downtime, understanding how and why this happens, and how preventative maintenance and vermin treatment can protect you, is the key to keeping your cooling safe.

Case file: The unexpected culprit

One day, A DEEPCHILL technician arrived at a Gold Coast home to inspect a Fujitsu air conditioner that had suddenly shut down. The smell of burnt electronics filled the air. When the cover was opened, the cause shocked even the technician: a green tree frog stuck to the PCB board, fried by the electrical surge. The short-circuit killed the frog instantly and destroyed the air conditioner.

This isn’t an isolated case. Across Queensland, one frog can short-circuit your air conditioner, leading to thousands in repairs and days without cooling.

A frog can short-circuit air conditioner by crawling onto the PCB board. Example shows need for vermin treatment, preventative maintenance, and professional air conditioning service Gold Coast.

How can frogs wreck an air conditioner?

At first glance, a tiny frog might not seem dangerous, but our technicians know otherwise.

  • Moisture magnet: Air conditioners release condensation. Frogs love water.
  • Food chain effect: Insects gather around lights → frogs chase insects → frogs crawl into ACs.
  • PCB vulnerability: Once inside, a frog’s moist skin bridges electrical components on the printed circuit board, triggering an instant short-circuit.

Consequence: a fried circuit board worth over several hundred dollars to replace, not including labour, lost cooling time, or replacement parts that can take weeks to arrive.

How to fix frogs’s problem

Once damage occurs, the only real solution is professional air conditioning service. A technician will replace the damaged PCB and check for further issues caused by the short circuit. But as with most HVAC problems, prevention is far better than repair.

Preventative maintenance & Vermin treatment

At DEEPCHILL, we recommend combining preventative maintenance with vermin treatment to keep frogs (and other pests) out of your system:

  • Protective coatings on circuit boards prevent pests from climbing or gripping.
  • Sealing vulnerable areas with shade cloth or mesh reduces entry points.
  • Strategic placement of new units away from lights helps minimise insect (and frog) attraction.
  • Regular servicing ensures technicians can spot signs of pests before they cause serious damage.

By investing in these simple steps, Gold Coast homeowners and businesses can avoid sudden breakdowns and the costly aftermath of a frog short-circuit.

Because when it comes to your comfort, no one should lose cooling to a frog.
