My Home Smells Strange

Mold and mildew are the main culprits behind musty odors in your home. This buildup can happen in the damp, stuffy, unventilated areas of your home or air system. Dirty ductwork can also contribute to your home's musty and stale smell.

What's Making Your Home Smell

Unsure where to look? Here's how to sniff out trouble and kick those bad home smells to the curb.

Potential Issues

  • indoor allergens
  • air smells strange
  • home is unusually dirty

Your ducts are the airways within your home. Any air that moves through your furnace or other HVAC systems does so within the ductwork. If your ducts have built up dust from a lack of maintenance or dirty air filters, that dust will continue to circulate throughout your home. Too much dust can even cause respiratory issues and allergies.

Sometimes, all your furnace needs is a quick filter change. When your heat is on, dust and other particles in your home's air get pulled in through the ducts and carried to the furnace. Just before they reach the furnace, a filter catches the larger particles like hair and dirt, trapping them and allowing cleaner air to move through. Debris and buildup on the filter can reduce the airflow through your system, which reduces its efficiency and puts strain on the system. Changing your furnace filter regularly will help prolong the life of your furnace. Having your duct system cleaned will allow for a healthy home environment.

  • air is humid
  • air smells strange

Warm, humid air coming in contact with cooler pipes and toilets causes the water in the air to form into water droplets, called condensation. The higher the humidity level, the higher the temperature needed to create condensation (known as the dew point). This means that as your humidity levels increase, cold surfaces that wouldn't typically gather condensation will suddenly start to sweat. Over time, high condensation in your home can damage the surfaces around your toilets and pipes. If your humidity level is over 55%, it can even create a cozy environment for mold and mildew to grow. Frequently wiping away the condensation will help in the short term, but you'll want to find a way to lower the humidity to prevent long-term damage.

Your AC unit works to cool the air in your home by way of its evaporator coils. The coils allow the cooling chemicals (needed to cool your air) to evaporate from liquid to gas and absorb the heat in your air, which is how your air gets cooled. Because this part is exposed to such cold temperatures, it is vulnerable to freezing. The coil will freeze if the system is low on refrigerant or has an airflow issue, as a result of a dirty coil, filter, fan wheel, or heat exchanger. If this occurs, and is not caught in time, the issue can escalate further and the larger refrigerant line may freeze. If this is the case, you will see ice on the suction line leading from the inside unit to the outdoor unit.
