You turn on your car and it works... do you ever have it serviced??


I do all my own auto servicing. There are specific pieces that are
subject to wear, corrosion, sacrificial fluids that need replacing.

It's my understanding that the "lubrication" in an A/C compressor is
contained within the freon, that if it has freon it's got lubrication.
Does one "change the oil" in an A/C system?


Your heating and cooling system is the single
most expensive appliance in your home, and it runs 24/7


Actually, mine only gets run sporadically. I don't run it day in, day
out. Only when it get hot or cold enough and only when I'm actually
home. There are probably people who run theirs more in a year than I
do in 5.

have it serviced??


Can you specify what servicing could be done to it to make it last
longer? Not being facetious, just seems that an auto and an A/C system
are different animals. I don't do "maintenance" on my computer hard
drives either, other than occasional defragging and antivirus scan.
But there's no actual mechanical "maintenance" to be done.

The word I keep hearing about many A/C companies who solicit for
"maintenance" is that many are shady, similar to companies who tell
you you need to put "treatment" in your septic tank, etc.
