I'd call for a clean and check from a local HVAC company. Ask your friends
and relatives who they use.

I'm very new to the heating and aC field. However, I assure you from
personal experience that a dirty AC system can use a LOT more electricity.
And a dirty AC doesn't cool as well. You will likely save the cost of the
service in lower electric.


You've been very new to the HVAC field for quite a few years...

This is the third summer of usage for our air conditioning unit. It's an
external unit that works through the central forced air system.

This summer the KW hrs usage is up about 60 pct over the last two summers.
Obviously, settings and weather influence it, but I'm wondering if it
could
be that it needs maintenance of some kind that would make it more
efficient
and use less electricity.

Any thoughts or ideas what I should look for to make sure it's not running
inefficiently?
