fyi central ac vs wall unit electric use

9 years ago

We live in SW FL. Hot/humid summers
We have been living with a 16000 BTU wall unit in our livingroom, for 8 years. It's only a 860 sf house, that has awning windows that don't seal great, but we love them because we can leave them open when it's raining, when not using ac
Running wall unit 24/7 was $128 - $175/mo.
We used fans to circulate air a bit, and tried to ignore the noise it made.
We finally installed a 2 ton 16 seer split system. Basic system. Nothing fancy.
Now it's quiet, and the whole house is comfortable without fans.
Last year vs this year elec cost.
July 2013 $143 2014 $102
Aug 2014 $160 2014 $116
