When was the last time that you cleaned or changed your air-distribution unit/system filter?

I wash mine every new season, so 4 times a year. Doing it on a specific date helps remind me to clean it. I have no idea about your other questions, but I have a really good air/heating guy that even comes on Sundays and doesn’t charge extra.

Thanks.

What months do you use your system or do you use it almost every day of the year?

I live in Los Angeles, and the longest consecutive period that I’ve gone without using any heating or AC is about 1 month.

Other than that, I just go a day or two without using either of them, and that can be even during our “winter” or summer.

I pretty much use mine everyday of the year. I might go a couple weeks in the spring and fall when I can open my windows, but not much more than that, unfortunately.

Every three months—- TOO much pollen… other stufffffff, need to do it tomorrow.

my thermostat has a timer that tells me to change the filter, based on how many hours it has been running. It’s been about 2 weeks on this one so far.
