I need some guidance on what to do regarding our Carrier A/C system. The fan motor works fine, the compressor turns-on, but I noticed yesterday that the copper lines where the gauges get installed were icey. The system is not blowing cold air to bring down the temperature in the room, even when set at 65 degrees.

I need to know what steps I should take before having a tech come out. I already changed the filter on the return. I don't think the capacitor is damaged, otherwise the compressor wouldn't be turning on. Air does blow through vents, it's just not cold. If there's something I need to check, please, I'm all ears. Thanks in advance.

1st thing,make sure you have a good clean furnace filter,bad air flow will cause it to freeze up. You might be low on freon,or your blower motor could be running to slow,if this the case a service tech will be your next step,, good luck

Is the furnance filter the same as the "air-return filter"? If not, where can I find the furnace filter?

Yes the same,, you shouldn`t have but the one filter,, is very important to keep it clean

Yep, filter was changed. Do you think it might be the evaporator coils that need cleaning?

Is possible , how old is unit? Unless the filter was NOT changed on a regular bases at sometime or another,, or unless there has been indoor pets that can clog the coil with hair and dander over a long period the coils don`t get that clogged very often, and you need to know what you are doing to clean a evaporator coil correctly,, the underside which can`t be seen is the main part that needs cleaned,plus special chemicals are needed to do it safely
