If you want to talk about modern home components that are truly valued when it comes to comfort, there is no doubt that the central air unit will come up. While a central air unit can make everything about dealing with summer temperatures easier, a faulty unit can be a major pain–especially if there is moisture involved. Older central air units are quite notorious for pushing excess moisture into the house when they have problems, but unless you are familiar with that fact, you will likely blame the problem on something else. Here are a few sneaky signs that you are dealing with moisture problems in your home’s central air unit.
You have odd odors radiating throughout your home that resemble the odor of stinky socks.
One of the telltale signs that you have moisture problems with a central air unit, whether it is in the ductwork or the unit itself, is an odd smell. If moisture is building up at any point within the system, it will eventually start to stagnate and mold and mildew can form. The smell that will be provided in the cooled air will almost always resemble something similar to the odor of old socks and should signal you that something is wrong. If the air coming through your vents is offensive, get in touch with a central air service like Central Aire Conditioning or others right away.
Your vent registries show signs of rust on the inside.
Even if you don’t catch onto moisture problems as soon as they are apparent, you will likely spot signs around the vent registries over time. If your vent registries are starting to get rusty, it is a good idea to have a technician come out and take a look at your unit to make sure there is not something wrong. A bit of outside rust is normal in some high-moisture areas, such as the bathroom. However, if the rust is more in the inside of the registries than the outside, it is a good sign that the air being forced through contains a higher level of moisture than it should.
There seems to be excess condensation when the unit is in operation.
A central air unit pulls in humid, hot air, dehumidifies it and sends it over a condenser for cooling. During this process, moisture should be fairly well eliminated by the time it makes it into your home. Many homeowners see what they believe is condensation on the walls around vents and assume this to be normal, which is true if the cold air is allowed to collide with hot surfaces or atmospheres. However, condensation should never be an issue if the house is already fairly cool, so what you see could actually be water droplets and moisture that is actually coming from within the air unit and this is never good.
