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
Do you change the oil in your car?
Do you change the filters every 30 days?
Why would you assume that something designed by, installed by man would not
need a check up?
I have my unit checked every year before I need it. Cheap insurance as far
as I am concerned.
Where I live has been more humid than usual this year. Yep the bill had
climbed a bit.
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.
In addition to the clean and check and perhaps even something you can
do, is inspect any ductwork you can get to. A small rodent sized hole
in a duct can dump a lot of cold air into the attic.
You can also have joints blow open and boxes get damaged.
