What’s That Strange Smell Coming From My Heat Pump?

Any strange smell coming from your heat pump in Jacksonville, FL, is a surefire sign that something is wrong. In most cases, you’ll need to schedule a professional repair or maintenance service. However, not every smell has the same significance. Here are four strange heat pump odors and what they mean for your system:

Burning Smells

If you notice a burning smell coming from your heat pump, it could mean that some system component is overheating and sizzling. More likely, it means that dust has accumulated on the blower or the electric heat strips. The smell you’ve noticed is the smell of burning dust. In either case, schedule an HVAC repair to find and fix the problem.

Sweet or Formaldehyde-Like Smells

Sweet smells like this are the signature indicators of a refrigerant leak. Refrigerant is a hazardous substance that smells sweet and ether-like. If you notice this odor in your home or around your outdoor unit, call a professional to schedule AC repairs right away.

Musty Smells

Smells like these indicate that moisture has accumulated somewhere in your heat pump where it shouldn’t have — probably in the system’s drain pan or condensate line. As this moisture accumulates, it enables the growth of biological contaminants or various types of bacteria inside your system. This is where the musty odor comes from.

Rotten Egg Smells

This sort of smell, if you encounter it, can be unbearable. It usually indicates that a mouse or other small animal has crawled into your system somewhere and died. To remove the odor, you’ll need a professional to open up your heat pump and remove the carcass.
