The air conditioning is set to 75 degrees. The actual temperature of the house is 79 degrees. The air conditioning was working the last time it got warm enough to need it.
How old is it? I had a problem with mine a couple of years back - I ended up needing a new condenser inside and a coolant fill. Much cheaper than replacing the whole thing! And it meant I won the bet I made when when I put it in. There was a coolant change going through at the time I bought mine - I could a 13.5 SEER unit using the old coolant, or a 14 SEER unit using the new coolant. The lifetime is supposed to be 15-20 years - the .5 SEER difference wouldn't pay back over the lifetime of the unit. However, if I had to refill the old coolant at any time after about the first 18 months, the cost difference for the coolant would more than cover the extra.
It's actually fairly new. I bought the house in 2003, and I was warned then that the roof, furnace, and air conditioner were all showing signs of age and would need replacement in the foreseeable future. Of those three, the only that's actually needed the replacement (so far) has been the air conditioner. The outside unit died a year later and I replaced both the inside and outside portions.
Which means that what I really need to do is call Standard Heating and Air Conditioning tomorrow instead of worrying, I suppose.
(LJ -- via ljarchive -- is very useful as a timebinding and reference device; it pinned down both the date of replacement and the vendor. I'd remembered the latter correctly, but was off by several years on the former.)
Here's a silly question, based on a mistake I made with my heat a few years ago.
Is the air conditioning turned *on* as well as being set to 75 degrees? I spent several chilly nights and darned near froze a guest and her daughter when I didn't notice my new set-back thermostats had to be turned to "heat" as well as setting the desired temperature. On mine, there's a 3-position switch under the cover: "heat, off, cool". Until I turned the switch from "off" to "heat," nothing I did to the temperature settings made any difference at all. In my defense, I'll note that my previous thermostats didn't have such a switch and I didn't think to look for one until after my guests were gone. Oops.
I just cleaned the little frilly grilly things inside of mine. It made a HUGE difference. The previous couple of years had built up an insulating layer of dust that seriously dropped the efficiency.

I was glad I'd gone with the 14.
