Hi!
Thanks for the extra tips

We do the cleaning, and I know it helps as the A/C even sounds better after a good cleaning (unless I'm imagining that part!), but it truly runs good, and we don't have the option of doing anything ceiling fan-wise or attic insulation as we rent, but it's a great idea for those who are home-owners. We do have one ceiling fan, that's only turned off to clean and another stand-up fan, that's turned off for the same reason.
The blinds are a problem, we keep all of them closed but one, the one the cats (spoiled things, but they're like our kids) look out of - I guess they get bored with us!
