Tonight

It was a cool morning today, cool enough that I broke out my winter jacket.  When the weather gets into the low 40s, it is time for the winter jacket.  It was grey until the afternoon, when the sun came out and it was bright and sunny.  The evening has cooled down, as it was last night.  

I used the heater in the computer room tonight, again.  Haiku spent some time with me in the computer room.  I have still decided not to turn on the furnace.  

I think we will be just fine over night, and it will be moderate enough tomorrow so I do not need the furnace. We shall see. 

HVAC Filter

I try to remember to replace the filter for my heater and air conditioner on a regular basis.  Most recently, I purchased a filter that was suppose to be good for 90 days.  I set a reminder on my computer, and replaced the filter this weekend.

The filter was totally covered with a layer of thick, gray cat hair.  Sake cat hair.  Well, 90 days is too long.  I set a reminder for 60 days, but as I was thinking about it as I wrote this blog, I decided I needed to check it at 30 days, and if it was okay, I could extend the check cycle. 

One of my co-workers has an HVAC license.  He says the most important way to do preventative care of our HVAC system is to change the filter.  I believe it.  I do change the filter regularly, and trying a filter that was suppose to be good for 90 days was an experiment for me (although I am not always 100% diligent at changing the filter on time.)
