How often should I get my air conditioner serviced? I have a trane Xr15 about 3-4 years old I think. I just bought the house last year so I'm not sure if it has had any maintenance done to it.  What all preventative maintenance do I need to do?

my guy does it once a year. Every once and awhile he shows me a part that is getting ready to fail so I have him replace it. This doesn't happen every year, but I have had no trouble since I started doing it 4 years ago. my system is 9 years old

every six months is recommended but at least once a year. Trane, Carrier and tempstar have all asked for customer records of maintenance being done when ordering replacement parts, based purely at random

Clean your condenser coils and change  your filters, you will rarely see the service man this way.

What about a window unit?

Keep everything clean, keep the fins outside washed out and clean, change filters regularly and check them monthly, make sure the condensate drain is open and quit giving money to "repair" people to "tune up" your A/C. Unless it's no longer cooling as it should and it sounds like it's not working properly, you're wasting your money. A Digital thermostat and a clamp or probe is really all someone needs to see if it's operating to spec as far as temps.

Amps draw is fast and easy for both compressor and fan, [outside unit, same for blower motor, cap readings, condition of the relay points. If it's running, sounds good, and cools as it always did, changing parts before they fail is a often nothing but a money maker.

Most people consider those disposable.

If its a larger unit you can slide out of the case you need to pull it out about 2/3 of the way and look at the inside of the cond coil. If its clean and you can see light through it easily it good. If its filthy and hardly any light can be seen through it you need to pull it out and clean that coil. I use foam and clean cond coil cleaner. Its strong stuff and burns when you get it on your skin but will make the coils look brand new.

Once a year have a professional come out.

Check, clean, or replace your filter every 30 days - 90 depending on the filter type and living conditions.

The easiest and most ignored maintenance.

I would say this is true. If you really feel ambitious, order a spare start/run capacitor to keep around. They are famous for failing on the hottest days of the year. Oh and mice are famous for getting on top of them and shorting them out.

5 year old house, and mine took a dump on the first hot day of the year.  It took me 10 minutes with the multimeter to figure out what it was, but it was late and the parts house didn't open until the next morning.  That was a miserable night.  In short, I missed a whole day of work (had to fix it, I was worried about my two toddlers), for a part that cost $8.33.

Have a spare.

I find more blocked EVAP or A coils than the condenser. Takes time to get in there, but cleaning them always makes a difference. Especially if smoker or pets and less than perfect filter changes or leaks around the filter.

Any signs of freezing typically means a pro needs to look at it. Otherwise, filter, clean condenser, and GTG.
