AC Smells Bad When Turned On

When your air conditioning system is working as it should, it will supply your home with cool and conditioned air. But as with any large home investment, your air conditioning system isn’t prone to malfunctions, including a less-than-pleasant smell coming from the air vents.

If your air conditioning smells bad when it kicks on, fear not. Here are three probable culprits and what you can do to address the issue.

3 Reasons Your AC Smells Bad When Turned On

1. Clogged AC Drain Line

Condensation builds up within your air conditioning system when it runs. This usually isn’t a problem thanks to the nifty component that drains the water outside to collect in the drain pan. However, over time, the drain pan can become clogged and result in excess water building up. And you know what can happen when excess water builds up where it shouldn’t—mold.

Luckily, unclogging a drain pan is simple with a little time and effort. Or you can call on your local HVAC technicians.

2. The Air Vents Are Holding Moisture

We live in Florida, which means we’re no strangers to humidity. This also means moisture affects our homes in ways it doesn’t for homeowners in other states. Excess moisture can build up within the air ducts of your central air conditioning system and settle near the air vent grates. This can cause a moldy scent to waft through the rooms of your home when your AC kicks on. If you suspect this is the cause of the smell, call your local HVAC company and ask about duct cleaning services.

3. Your AC Is the Wrong Size for Your Home

This is a less common issue but it happens. Sometimes we purchase an air conditioning system that isn’t the right size for our homes. If your AC is too large for your home, it can cause the air to cycle through your home too fast. This means the air won’t have time to be properly dehumidified and excess moisture can sit within your ductwork. Although uncommon, if you’re not sure if your system is the right size for your home, our team can determine which system is best for your home’s unique needs.
