Howdy Grichards360,
Not knowing the
AGE of your
AC only makes it a wee
bit harder to speculate... (good news though)...
INTERMITENT operation =
cheap & easy.
SUFFICE it to say
REALLY EXPENSIVE issues
are like
HATE & UGLY... They stay (and accumulate).
My BEST GUESS is your
system pressure is
right at the
THRESHOLD where designers
have CORRECTLY (even mercifully) decided it is
marginal enough not to USELESSLY operate the
components at all...
An ideal time (and stable enough system) to
"
top-up" your refrigerant charge... (see below)
unless you live in CALIFORNIA ... you should easily be able to purchase a kit to accomplish this TASK yourself.
Two CAUTIONS here:
1). Refrigerants can be quite
dangerous...
(read & heed precautions (especially
refrigerant TYPE)).
2). "
Top-Up" is a STUNT...
Proper maintenance would
dictate a serious consideration be given to PROPER
lubrication. If this is the first time in 10 or 15years you will
PROBABLY be fine...
(ELSE: study up or comment back).
Hope this helps
