As spring fades away, people all over the United States are switching on their home's central air conditioning systems. Unfortunately, some of those individuals are going to experience an unpleasant surprise when their system turns on and blows out a bad odor. It's not unusual to find a home where the air conditioning is churning out obnoxious smells, and the problem can be so bad in some homes that it forces residents to leave their systems turned-off. Below is more information on the causes of odor in the air conditioning system and what you can do to alleviate the problem:
Some common odors and their causes
Several kinds of air conditioning odors can cause problems for homeowners, and each one has its own unique smell to help locate the problem. Here is a list of common smells and their causes:
Addressing the problems
For odors that have their origin in mold or mildew growth, the first goal is to eliminate sources of moisture in your central air conditioning system. Here are some specific measures you can take to dry it out:
Change the air filters often
The return air vent filters in your air conditioning system are subject to collecting moisture and growing mold or mildew. That's why your filters should be changed frequently during the periods of highest use; once per month is the minimum recommended interval, and more often is better. Also, use spun glass filters whenever possible; they are not only the lowest cost filters available, they also allow maximum air flow through the medium. High air flow helps keep the filter dry.
Unclog blocked condensation drainage lines
Your air conditioner's evaporator both cools and dries the warm, humid air that flows through it. The water removed from the air is collected and drained from the unit via a condensation drainage line. This line is a small-diameter PVC pipe routed through the exterior wall of your home where it drains out on to the ground.
If the line becomes clogged with slime or other material, then water will back up and stagnate. You can clear blocked lines using ordinary household bleach; most lines have an access point for adding bleach or cleaning with a pipe-cleaning brush. If your drainage line does not provide access, then you can cut the line in half using a tubing cutter and insert a PVC tee fitting for access in the future. Simply pour a cup of bleach into the pipe and allow it to work through the clog.
Keep dry air moving
Another way to prevent mold and mildew is to keep dry air moving inside the system. During periods when the air conditioner is shut down, moisture can become trapped inside the ducts, filters and related components. If your central air conditioning system serves dual-duty as your home's heating system, then you should occasionally run the heater during mild weather to dry out the duct work and other interior spaces.
If you suspect that the odor is caused by a dead animal, sewer gas, or an electrical problem, then you will need to contact a qualified air conditioning professional for assistance. They will be able to inspect the inside of the duct work to locate and remove animal carcasses. In addition, they can identify if there is a dangerous tie-in to leaking gases. Only a professional can thoroughly inspect the system's electrical components to see if a failure has occurred and repair it before a dangerous fire erupts.

For years, my wife and I debated on what we wanted to do with all of the spare land in the back of our house. We were lucky enough to buy a house on an extra-large lot for a great deal, but the land was "going to waste" for quite a while. One day, we finally decided to have a guest house built on it, and now that the house is finished, we wish we had built it long ago. We are now renting it out for some extra income, and it is helping us save for retirement. I have always been fascinated by construction, so I enjoyed watching the professionals build the guest house and learned a lot during the process. I decided to fill some free time by blogging about the experience and sharing some construction info I learned during the process. Come back soon!
