My lack of knowledge of how the ac unit that is outside manages to cool the air that comes through my vents is likely the cause of my ignorance behind this question. Please explain this to me.Do I need to change my furnace filter even when I'm using the a/c?yes if your a/c and your heat use the same ductsDo I need to change my furnace filter even when I'm using the a/c?yes, because the fan is still running and circulating air.Do I need to change my furnace filter even when I'm using the a/c?Your heating system and air conditioning system both deliver air to the inside of your home via the same ducting. I would alos assume the air uses the same fan motor to push the air. So, yes, you need to change your filter all year round. One thing to consider when buying a filter is the total size and the thickness. Read the manufacturers advice as to how often to change the filter. Also, consider what you want to trap in the filter and above all, don't skimp on cost, there are many filters to suit any need, from just dust collection to heavy pollutents, so choose widely and but reasonably based on what you want to control.
I hope this helps, good luck!
rentahandyman@yahoo.comDo I need to change my furnace filter even when I'm using the a/c?Your furnace and air conditioning work together to take the heat out of the air. The hot air in your house is pulled into the furnace where the heat from the air is transfered to the refridgerant, taken outside and disapated. The cooled refrigerant is then sent back to the furnace and air is passed through the cooled coils and then your furnace filter and then the rest of the vent work. Your air is filtered at all times unless you do not run the ac or heat. Change your filter as often as the type of filter you have in there specifys--They cost anywhere from 99 cents to a couple bucks depending on the quality.--and yes you can do it yourself. Please ask more questions--us men love ladies in distress!!Do I need to change my furnace filter even when I'm using the a/c?of all the concerns...ok the system may or not...run through the duct work at the filter....on a good fresh air system...it would or even have a seperate system...because of outside dust and debris.....so for 3.75 a pop.....check and change it.....do this a few times....record the weight of yr filter....if it's exact...ot won't change...if it weighs more...its worknDo I need to change my furnace filter even when I'm using the a/c?it keeps the doodoo off your coil, which in turn would build up into sludge, grow black mold %26amp; in turn the mold continues to advance out to the registers %26amp; it looks like soot is around your registers! wait a minute are you my aunt?Do I need to change my furnace filter even when I'm using the a/c?Thank you for asking,,, and even admitting ignorance,,,which by the way is not a sin, or a capital offense. many of us are about many things.
You state Furnace, and AC unit outside. Is each a separate system, or use different fuels or power sources?
If in fact you had/have a Heat Pump system that offers both then your filters should be located in air %26quot;returns%26quot; somewhere in the house. An AC unit has no real FILTER system by itself.
The %26quot;registers%26quot; or %26quot;vents%26quot; obviously are where the air,,, heated or cooled, flows into each room. Unless this an an older home I can't imagine an AC units delivery and return system being tied in to a furnace that may have separate fuel or power sources.
IE: If I had a gas or fuel oil furnace and a separate AC system, I'd want to keep them separate,,even if more registers and returns had to be installed.
I guess answers could be more helpful with more detail.

%26quot;We never close%26quot;Do I need to change my furnace filter even when I'm using the a/c?Hang on kid. Too much information and not enough knowledge can be dangerous, as exhibited by some of the answers. The air in your home is circulated through the air handle for both a/c and heat. Yes change your filter every three monthsDo I need to change my furnace filter even when I'm using the a/c?Buy the cheapest (fiberglass) filters (l2 in a case) and change them on the same date every month. The air that comes through your vents is not being cooled in that piece of OUTSIDE equipment. The air is being cooled in that piece of equipment that is INSIDE your home. Be assured that changing the filter every month will prevent problems and cause your equipment to operate more efficiently. Good luck.Do I need to change my furnace filter even when I'm using the a/c?Yes your vents are used for both the furnace and A/C. You should change your filters every 3 months. Don't but the cheap blue fiberglass filters with the circular holes, they are worthless. Get the pleated filters that trap pollen and dust.Do I need to change my furnace filter even when I'm using the a/c?Buy cheap filters and change every month, you will have the least problems this way.
