We turned our a/c on yesterday for the first time this season. It was about 85' outside, the thermostat (as it's always been) was set to 75', but the interior of the house never got below 76' and in fact climbed up to 82' as the day went on. So obviously something was wrong.
I checked that the system seemed to be working okay, didn't see any frost or signs of freezing up, no apparent leaks, the hardware outside was working fine, and so on: it just wasn't cooling the air as much as it should've been.
When I checked the filter, it wasn't horribly gunky but was definitely more grey than pristine white. It was last replaced in late January and hadn't been touched since then, so about three months old. I swapped it out for a new this morning today and now a/c seems to be running stable at 75'.
I'll be the first to admit I don't always remember to replace the filter every month (or two or three) but having almost ten degrees' difference between the old and new filters seems surprising. Can that really have such a drastic effect on temperature control?
Thanks!
Can filter affect interior temp by almost 10 degrees?
