Your air conditioning system has probably been running steadily since the spring, and you can expect to keep using it on and off until its next maintenance check-up in the coming spring. That’s just the way life in a warm Southern California. But all this work will take a large toll on the system even before its maintenance appointment, so you need to watch for signs that something is wrong. One of those signs is when your AC starts emitting unpleasant smells.
The most common odor complaint people have about ACs is a smell like mildew coming from them. This means the air conditioner has fungus or mildew growing inside it, which occurs because the moisture that collects along the evaporator coil isn’t draining properly. This can seriously hamper your air conditioner’s performance, and you will need to call a professional to clean the coils. The issue could come from mold in the air filter, so make sure your change or clean it.
Dirty sock odor
This is another frequent odor issue from an AC, and the source is probably an air filter that’s heavily clogged. Remember that you must change or clean the filter once a month during periods when the air conditioner works daily, and every 3 months during more dormant times.
Exhaust fumes odor
Your air conditioner doesn’t run from natural gas, so why should it start emitting the smell of exhaust fumes? The reason is that the motors are probably leaking fluid or burning out, and this will create the unpleasant exhaust smell. Get repair technicians on the job right away!
A ruptured sewer line near the ductwork system—even a small one—will spread around awful-smelling fumes. Some of these gases, like methane, are dangerous, so have an HVAC expert in to look at your AC and ductwork immediately. You’ll probably need a plumber at some point as well.
