I just bought an older home.

The furnace, A/C, and windows are functional, but I suspect there may be some efficiency gains to be made.

Is there any way to determine/estimate how efficient those are currently? I would like to see if it makes sense to spend the money to upgrade them based on ROI on my utility bills.

this question is far too broad as it stands. The only answer to the question as you posed it is "hire someone to do an energy efficiency audit" –  mac Sep 19 '13 at 19:23
    
@mac: Does an "energy efficiency audit" require expensive, specialized tools? If not, I see no reason why he couldn't do that himself. –  BlueRaja - Danny Pflughoeft Sep 19 '13 at 20:15

As far as I am concerned an energy audit is a good answer - I am aware that the question is broad. I honestly did not know whether the task of estimating energy consumption of a home was something that could be done with any sort of accuracy. –  javanix Sep 19 '13 at 20:59

@BlueRaja-DannyPflughoeft A blower door is a couple grand, an infrared camera is another couple grand. So for a cool ~$4000.00 you can do your own energy audit, but you'd better find some big problems if you want to save $4,000.00 on your energy bills. –  Tester101 Sep 20 '13 at 10:17

As mac has mentioned, an energy audit is a logical starting point. I would shop for a "blower door" test that measures actual system air leakage. The other test would be a thermal IR scan, that will reveal relative hot/cold spots. Some utilities offer discounted audits.
