I have a problem with the pressure on a unit.
Suction 45-50 lbs
Liquid line 210
super heat 15
sub cool 20
return air 72
supply air 54
good amount of air flow.
Can not get suction pressure up. I can't seem to figure out the problem(if i even do have one) Anybody have any ideas

Type of unit, brand, model #, refrigerant might be helpful. Also maybe operating conditions.

it appears that all is operating ok...even if i dont know exactly what you have. assuming txv and dx cooling coil, you are not getting the heat out of the coil and into the refrigerant...dirty coil on the air side or dirty tubes on the refrigerant side (like from an old burn out or something).
a little more info would really help...i really hate assuming.

Just because you can measure it, doesn't mean it is important. Just because you can't measure it, doesn't mean it isn't important.

What is your outdoor temperature? You subcool seems a bit high but if you have a low OAT then your subcool will be a bit high. I also really don't see anything wrong especially with the low high side pressure.

sounds like a dirty evaporator (indoor) on a heat-pump.

Granted we need more info. but why? A TD on the indoor coil of 18 deg and a superheat of 15 deg sounds great to me.Originally Posted by tex~n~oz
