Why Does My Air Conditioner Smell?
Air Conditioner Smell
Here in Portland, OR we have had a couple of days of warm weather. Many of you may have turned on your air conditioner for the first time and noticed a smell. That is the air conditioner smell of mold and mildew coming thru your duct work.
Why Does It Smell?
Your air conditioner is a dehumidifier. When you use your air conditioner, you are removing heat from your home. When this happens your air conditioner is also removing some moisture from the air. If you have an air conditioner that is too big for your home then it it won’t run long enough to properly dehumidify the air.
Have you checked your filters? If your filter if clogged or exposed to too much moisture, mildew will grow. It just takes a little bit of those pesky particles to cause the mildew to grow. You should check your filters every 2-3 months just to make sure they aren’t clogged or dirty. If they are, change them.
Your drip pan is another cause. If the drip pan is clogged (filling up too fast), this will cause mildew to grow around and even in your system. If you can easily clear the clog, then your good to go, otherwise you will need to contact a reputable HVAC contractor.
You could also have a clogged condensate drain. The condensate line runs from the coils to the outside. It removes the condensation that is created by the air conditioner. When this becomes clogged, you get mildew.
Then there is your duct work. Your duct work if not sealed properly will cause your duct work to be damp. If you have too much moisture in your ducts then you could have mold and mildew developing in your duct work. This will travel thru your house as the air blows thru your ducts.
If the smell is like rotten eggs… You may have a dead animal. If the smell is stronger the closer you get to your vents, your seeing hair or droppings in the duct work, then you will want to contact an exterminator. You may then need to have an HVAC contractor come out and inspect the duct work for an repairs or replacements. You will want to ensure that you have sealed up all access to duct work.
