What’s the Odor Coming from My AC?

Nov 19, 2021

Your air conditioning system is responsible for delivering cool air throughout your home. Thankfully, a typical HVAC system will last around 15 years before it needs to be replaced. However, it’s made up of several components that can break down along the way and shorten its lifespan. Unfortunately, catching these issues isn’t always as easy as your unit shutting off.

Sometimes symptoms pop up around or inside your home that can signal the need for repairs. So, how do you know if your AC is doing its job correctly? Our experts at Hobson AC have the answers. Keep reading to find out ways to be sure your AC is maximizing its efficiency.

3 Common Signs Your AC Isn’t Working Correctly

If you notice these common signs your AC isn’t working correctly, you should call a professional HVAC technician to inspect and repair or replace your system:

  • Warm air
  • Irregular cooling cycles
  • Foul odors

Warm Air

Warm air can mean several things in the AC world. While it may be an easy repair like restoring your fan or fixing thermostat functions, it can also signal the need for serious repairs like managing refrigerant leaks and electrical wiring in your HVAC system. Serious issues should be handled by professionals because electricity and chemicals are dangerous and can be deadly.

Irregular Cooling Cycles

The size of your unit can impact its cooling cycles. While an AC unit being too small for a room or home is a problem, one that is too big also causes issues. A unit that is too large for your home will shut off before a full cooling cycle is up because it reaches the intended temperature too quickly. This allows the room to heat back up before the next cooling cycle starts.

Irregular cooling cycles can also be due to a safety feature on your unit. A modern HVAC system may cut a cooling cycle if it detects voltage that is too high, in order to protect you and your family from electrical fires. Window air conditioners are often sold in 110-volt models, while central air systems need double the power to operate. 

Foul Odors

Depending on which strange smells your AC unit is emitting, it can mean different issues. Musty odors that have a hint of woodiness often signal mold or mildew growing in your unit, while a dirty sock smell likely indicates the need for a filter change. However, some odors can be dangerous, like a gas smell.

If you smell gas in your home or coming from your air conditioning system, you should open as many windows as you can and quickly call your local fire department to inspect your home for a potential gas leak. Gas leaks can poison humans and animals and cause fires in your home.

Deciphering AC Odors

When you start to smell a foul odor in your home, your mind may start racing to try to figure out the source of the smell.

Odors coming from your vents and especially your AC need to be dealt with immediately. It’s not always obvious what is causing the smell, which is why consulting a professional is always recommended. Here are some of the most common smells associated with your AC.

Mold Growth

Because of the cool and warm air mixing inside your AC system, condensation is created in the process. This condensation often leads to mold or mildew growth inside your system. Over time, the smell of mold will travel throughout your home.

Mold can also grow on your air filter, so make sure to change it once it is full.

Burning

A burning smell is never something to ignore. If the odor is coming from your air vents or ductwork, it could indicate an electrical or mechanical problem with your AC unit. It’s important to have this looked at as soon as possible by an HVAC professional. Not only could this mean damage to your system, but it could potentially be dangerous. Also, be aware if this smell comes directly from your outdoor AC unit. If it does, turn off the unit and contact your local HVAC professional.

Something Rotten

There are a variety of rotten smells that could come from your vents. It may be something decomposing, rotten eggs, or what is known as “stinky feet.”

If it smells like something is decomposing, an animal may have entered your vents at some point, likely during the winter, and got stuck. Rotten egg smell is usually associated with a gas leak or sewage. It’s possible that a line broke near your air ducts and the odor is seeping into your ductwork. Don’t ignore this – have an HVAC professional get to the bottom of whatever is causing the gross smell.
