Some Important Factors to Consider Regarding Air Filters

thermometerIt’s often the smallest details that cause the biggest problems with climate control systems (and with life in general). You can’t really be blamed for not knowing every little part of your furnace and how it operates. However, if you want to keep your system in the best possible condition, though, there are certain things you’re going to need to be careful about. One of those things is the air filter.

The Air Filter

The air filter sits in the furnaces’ air return duct. All air that enters the furnace must first pass through the air filter. The filter captures dust and debris that might otherwise hinder the operation of the furnace, helping it to stay in good condition. This method of protecting the system is quite effective, though it’s not without issues. The biggest problem is that the filter can’t get rid of the contaminants that it collects. If the filter is not cleaned out every few months, it will become so clogged that most of the air flow to the furnace will be cut off. That’s when problems start to occur.

Problems

Eliminating most of the air flow into the furnace will trap the heat it produces inside it. This will cause the temperature of the furnace to rise to unsafe levels, which will activate the limit switch. The limit switch will shut down the furnace to prevent it from becoming damaged by overheating. However, this doesn’t solve the core problem. When the furnace turns back on again and attempts to finish its cycle, it will simply overheat once more and shut down again. This rapid on/off behavior is called short cycling.

Furnaces are designed to operate in specific heating cycles, and they start to have trouble if they aren’t able to complete those cycles. The wear and tear on the various parts of the furnace will dramatically increase, causing them to wear out more quickly and break down more often. If the furnace is allowed to short cycle for a long enough period of time, you will find your repair costs will rise significantly. Short cycling also lowers the output of the system by a substantial amount, since the furnace can’t actually distribute the heated air.

Finally, the added strain on the system will eventually prove too much for it to cope with. If the furnace has a prolonged period of short cycling, it will have its lifespan shortened by a number of years. This is one of the biggest reasons that you should call for repairs as soon as you notice your system short cycling. The faster you can have it repaired, the more damage to the system you can prevent. Otherwise, you’ll be doing your furnace quite a disservice.
