If you’re at home during the heat of the summer enjoying your comfortable and conditioned air, the last thing you want is to start to smell a funky, musty smell. Unfortunately, a musty, funky, or mildewy smell can be a common residential air conditioner issue, but on the bright side, it’s often a very easy fix for HVAC technicians. Here are a few reasons why your air conditioner may be giving off a musty smell.
Wrong AC Unit Size
A lot of homeowners think that the biggest or most expensive air conditioner is the best choice for their home, in reality, the best air conditioner is the one that is the right size for your home’s square footage. If you have an air conditioner that is too large for your home, your air is going to be recycled too quickly, not adequately drying the moisture from your home’s air and allowing for bacterial growth.
Excess Moisture In Ducts And Vents
One of the most common reasons that your air conditioner is giving off a musty smell is the presence of mould or bacteria in your ducts or vents. This happens when a home is too humid or there is a drainage leak in your system. Remember that breathing in mould and mildew can be dangerous for the lungs, so be sure to call the experts at Team Harding for help if you believe this is the problem.
Blocked Condensate Line
The condensate line is a small PVC pipe tasked with draining any condensation from your air conditioner through to the outside of your home. While this pipe is completely necessary, it is very small in size and can become easily clogged leading to the growth of mould and bacteria.
A Clogged Air Filter
During both the winter and the summer months, it’s absolutely essential that you change your air filter at least once every 90 days. A clogged air filter can cause recycled air to become obstructed, leading to humidity and mould growth. If your air conditioner is producing a musty smell, make sure that your air filter is clean and fresh.
A Full Drain Pan
As condensation is created by the humidity being taken out of your home’s air, the water is collected in what’s called a drain pan. After years of use, sometimes the drain pan becomes inefficient from wear and tear. If your air conditioner is producing a musty smell, check to see if your drain pan is full, because a full drain pan can begin to grow mould.
