I live by myself in a 1600 sq ft or so single level rancher type residence built circa 1952. There is some some fiberglass batting in the attic but otherwise house is not particularly well insulated.
I typically resist using the AC until it’s unbearably hot. For cooling I use two big Patton floor fans facing where I sit. They are noisy but it’s just me in the house so no one cares.
I have while house AC and a relatively new heat pump that’s 4 years old. It cools the house nicely but jumps up my electric bills an additional $100. - $150. + a month if I use it regularly.
Sleeping is the worst scenario if the weather is hot and sticky and have a fan blowing on you all night can sometime get irritating.
I’m wondering if buying a small window AC for my approx 300 sq ft bedroom and using it just for sleeping makes sense vs the whole house AC.
