Home ac having problems - freon doesn't seem to be circulating

After reading your messages, and your replies to the
tradesmen who have commented. It's obvious to me that you're
a hard core do it yourselfer. And that if a tradesman writes

While I am willing to know when I need a pro.

"Well, your service guy needs to.... A, B, C..... that you
will take the covers off, and do your own version of what
the service guys do. Which may help, or it might not.

I doubt I will see a problem. I don't know what to look for.

I've been servicing refrigeration and AC systems long enough
to know that there are a lot of things that are not obvious
to the untrained eye. I'm in the rapid learning part of my
career, it seems that every time I service a system, I learn
somthing new. I've only been in the trade for 15 years. So,
I encourage you to ask your friends and neighbors, and see
who they reccomend.

I have a company coming out tomorrow to check mine. I probably do not need
a full HVAC reoplacement (combined heat and AC and heat worked while AC is
under cooling). All I know we skipped HVAC maintenance while paying off
25,000$ in rental damage and some 5,000$ in materials to 'DIY' repairs.

I am pretty sure we just need added coolant. We have not done that in 3
years since return as as far as we lnow, it was last done in 1998. The
renters were not bashful at all at getting contractors in the reducing their
rent by the cost and filing after the fact but there is no referent to Freon
added. Heck I was in Japan. I can just reasonably guess last fill was 1998.

In my case, still have AC but it is not as cool as it should be. Last year
it was 'ok' but I recall it being better.

Professionals due in tomorrow to service the unit and do what is needed.

Have them flush it out and change it if it has been that long.

OK just so you know, house AC systems have a hermetically sealed refrigerant
circuit, that means the entire thing is all metal except for the Fusite
where the electrical terminals enter the compressor. As such the system
should NEVER require adding refrigerant EVER. If it needs any added then
there is a leak somewhere plain and simple. Car systems however can
sometimes require topping off every several years due to the refrigerant
permeating through the rubber hoses.

And the term is refrigerant not "Freon" or coolant. Freon is DuPont's trade
name for CFC and HCFC refrigerants manufactured by them This does include
R22. However DuPont's trade name for HFC refrigerants such as R134a is
Suva. Hence anyone you may hear referring to the refrigerant in their '94
or newer car as Freon is dead wrong. The same can be said for anyone with a
new AC system using R410a

Coolant stays the same phase (solid, liquid, gas) as it carries heat around,
refrigerant changes phases.
