When it is being used, a furnace’s filter should be cleaned or replaced about once a month. This allows the furnace to operate at maximum efficiency. When a filter is clogged, it takes more energy to heat your home which costs more money. There are various types of filters and if you use a replaceable one those can be easily purchased at a hardware store. More advanced filters are not replaced each month, but cleaned.
Whether you are cleaning or replacing, here are some instructions:
- -Turn off the furnace either at the main circuit breaker or the service panel on the furnace.
- -Look for the filter, a square or rectangular mesh device, usually found near the blower.
- -Remove the filter and wash it if necessary. Before putting it back in the furnace, make sure that it is dry!
- -If you bought a new one, check to be sure it is the right size and then replace the old one.
This might seem like a hassle, but it is well worth it for both your furnace and your wallet. Questions? Contact Flame! I received much of my information from this website, so check it out for more info. EHow “How to Clean or Replace a Furnace Filter.”
