how'bout some periods so we can make sense of your post.

What do you interpret as the lo and hi side? Would be helpful to know so we can direct you.

and what were the pressures? How did you measure them? Gotta know so i can determine how accurate they are.

 

[egcollom]

okay, i dont have my gauges in front of me but this is what i have wrote down in my log book. at 9 pm on the low side it read 98 lbs on the high side it was 210 lbs.
room temp was 80.5 air temp coming out of air duct was 69.8

Gee, your right...it's broke!

Try a little manners friend. I don't need the 'tude when I'm giving free advice this time of the morning. I asked those question to try to help you but you can get nasty with the trolls who frequent here.

 

[egcollom]

sorry!!!! I have fixed holes in the duct work, and lose wires on the unit, it is starting to get to me im new at this stuff please give me some help

 

[hvaclover]

my ac is working. Good night.

 

[egcollom]

do you have any thought of what else i need to do

 

[beenthere]

Is it a heat pump.

 

[egcollom]

no it is not a heat pump, standard two pcs unit gas heat, r22 freeon it is a goodman

 

[beenthere]

What was the outside temp when you took these readings.

 

[egcollom]

about 100' outside 85 inside

 

[beenthere]

210 PSIG head pressure is a saturation temp below ouotdoor ambient.
A restricting liquid line filter drier installed inside the condenser can cause that.
Or a low charge.

You should take all readings again.
And record indoor drybuld temp and wet bulb temp.
Out door drybulb temp.
Head pressure, and liquid line temp.
Vapor pressure and vapor line temp.

Entering and leaving wetbulb and dry bulb temps at the coil(not at registers).
