Addressing Unusual Smells Coming From Your Heat Pump

There are some noticeable signs that will tell you your heat pump is failing. Unpleasant smells are one of the surest indicators that your system needs a repair, or perhaps even a replacement. However, not all odors are alike, so it could be challenging to determine the origin of your unit’s deterioration. In this post, your AC troubleshooting system experts share some of the common heat pump odors that homeowners should know about: 

1. A burning electrical smell. This is one of the most common smells you’ll encounter. If you notice a burning odor coming from your system, this could indicate a severe problem, such as damage to your wiring or the motor itself. It’s best to call a professional in this instance to ensure the safety of you and your equipment.

2. A musty smell. This musty odor is often referred to as “dirty sock syndrome.” If you notice this smell, it could mean that mold, mildew or bacteria is accumulating on the wet evaporator coils or the ductwork. Although this may sound like a worrying problem, the solution is simple: you can either clean your existing filters or have them replaced.

3. Sulfur. Air conditioning replacement companies say that this is similar to the burning odor, and indicates there’s a significant issue that people shouldn’t ignore. This smell usually comes from gas furnaces and warns that there’s a gas leak on your property. Indeed, it will alert you that your home isn’t safe, in which case you’re urged to contact an HVAC expert to have the system repaired.

4. A dusty smell. This is also considered a typical odor, and is mainly the result of dust and debris settling on your unit’s components. Pro tip: you can wait it out. Experts say the smell is likely to go away naturally as the dust burns off. However, if the scent lingers, this could mean that your unit needs an in-depth cleaning.
