Furnace filters and A/C q's...

I just changed my furnace filters, are there different filters for the A/C? I have central air and the A/C "box" (Big giant fan) is outside on the side of the house. I am a first home owner and dont have all the knowledge I need...thanks in advance...

Hello: Dan

Usually only one filter beneath the blower in a vertical unit. One in the intake ducting for a horizontal furnace.

You mentioned filters, as in pural, multiple filters? Some older units did have multiple filters. Up at the A/C coils. Also units with multiple intakes. Is that what is meant by filters?

Usually ther is not seperate filters for the A/C in a dual pack. (combo heating and A/C unit) The unit outside is the cooling fan for the A/C coils only. No filter there. Cleaning does help...

You dont say what furnace you have there. But look at the filter rack there it should like show you how they go in. Most of the time when you have 2 frilters there they go in like /\ . look and see how the frame for them works. Be sure and change them every 30 to 90 days for heat and AC. Also before you turn the AC on go out and with a small stick give that fan there a push to see that the fan blades are clear. Some times bugs get in and can lock up the fan and when you turn it on it can burn out the fan motor. Thats why to just see if it spins ok . You can take a water hose and just hose out the coil on the outdoor unit power off and see that it is clear and no bushes around it for 18" or more so it can get air. ED

Sounds like you have a counter flow blowing down. With the furnace set on top of the AC coil. Are you on a slab or over a crawl space here. What ever just keep the filters clean. ED

Its in the garage (upright) if thats what you mean, so the airflow should be pointing outwards on both filters? When we had the house inspection we had the furnace serviced and filters changed and thats how they were put in.....one pointing out and one pointing in....doesnt make sense to me but thats why im here!

A picture would be nice if you can do it.. This web server won't allow you to do a pix posting, so you will have to post it else where and link us to it.

The pictures didn't come up either on my end. (Wrong web address?)

From what you've said, sounds like the filter is set up right if it's a down flow ( V )

Make sure your filter arrows are pointing down to the blower.
