An air conditioner that is working properly is something most people take for granted. Obviously, you have a lot of other very important things on your mind. But, if you get home and realize your home smells musty, it could be from the cooling system. And you might need air conditioning repair in Los Gatos, CA to correct the issue. Here are some of the reasons why your cooling might smell musty and what you can do about it.
Blocked Air Filters
The filters on the air conditioner are designed to block tiny particles from getting into the system and circulating into the air. But if the filters get clogged, they can cause any number of problems. When the particles trapped by the filters are exposed to moisture they can produce mildew. And every time the air conditioner runs it will create a stale odor. So the first thing you might want to check is the filters for your HVAC system.
Air Ducts Holding Excess Moisture
We have our fair share of humidity in the area. And humidity can directly cause moisture to build up in the ducts of the air conditioning system. It might come and go without intervention. But if the smell of mildew is a common problem, you might want to schedule a professional air duct cleaning with an HVAC technician.
Frozen Evaporator Coils
How do air conditioners work? Well, they absorb air from inside the home and rapidly cool it by removing humidity. Then the fans cycle it back into the home through the return vents. But if air cannot flow freely through the system it can cause water drops from the humid air to collect on the evaporator coils. And as the refrigerant cools the air, the water will freeze on the coils.
Full Drain Pan
When the cooling system removes humidity from the air, the water has to go somewhere. This is where the drain pan comes into play. The water droplets fall into the drain pan and then down the drain. But after a lot of use, the drain pan will see some wear and tear. Eventually, it can become rusted and the water collects in the pan. Mold can build up, and you will be able to smell it.
Clogged Condensate Lines
Water from the drain pan moves through a part called the condensate line. This is a visible PVC pipe that allows water to flow from the pan over to a drain. Because the part is small it can become a prime location for mold and mildew. If the sludge gets too thick it can cause a block in the pipe and the utility closet will start to smell musty. To prevent this, you should try and clean the condensate line at least once a month. It’s pretty easy. Just turn off the air conditioner at the thermostat and the breaker panel. Then remove the cap on the line, pour in some distilled vinegar, and allow it to sit for a few minutes, then replace the cap and turn the air conditioner back on.
Does your cooling system smell musty every time it runs? Then it might be time to call for air conditioning repair in Los Gatos, CA.
