Seriously, is it long cycling, getting adequate cooling, etc?

When was it last checked for charge and everything cleaned?

Yep. Years of dust & dirt building up on the fins, plus the grass the lawnmower tosses on it, causes it to overheat because it can't draw air.

Check for even Voltage drop at start if 240 Volt 1 phase unit.

Use laser pointer thermometer on every connection back to main panel for above ambient temps. After having run awhile....

Re torque all lugs back to main service entrance.

have reset switch replaced with new one that is in spec.

Use laser thermometer on reset button for data on its operating temperature.

Have you suffered added heat loads to the condenser location, such as added nearby condensers or loss of shade trees/ buildings?

12 year old tech, you might save $ upgrading to a multi-speed system...

wife likes it at 70 ,wondering if thats the problem
its been high 90`s these days
everything is clean.
i clean the filter every week (wifes a fanatic )

but since she likes it cold , it runs almost all day

i did notice its sucking hard on the bi-fold door , like its fighting to get enough air , so i keep that open , till i can put a 2x2 return vent in the opposite wall.

today , stil hot as hell out , the thing didn`t stop , didn`t need to push reset button

its on the west side of my house , and after 1 or so it is right in the sun, no shade to speak of
should i make a shade of some type , so its not in the direct sun?

all your other comments are beyond my experience .
wood , and remodeling is my game , but i`m not mechanically inclined , and as for electric, i install recessed lights , and switches , and receptacles m now and then , but only when we`re talking " a black , and white wire , and a ground ( i don`t run lines )
but thanks
should i have an electrician come and check it? or a/c guy?

Re: "Help! My AC Isn't Working!....


A shade may actually work against you by impeding the air flow carrying the heat away.

We're not referring to cleaning the furnace filter here. Is the unit outside clean? Are the metal fins clean of debris and grass clippings? Are a lot of them crushed and bent over? Those fins are what dissipates the heat you've collected inside and are dumping outside. Crumpled fins or fins covered with foreign matter makes it hard to transfer that heat to the surround air that's being pulled in by the fan.

Re: "Help! My AC Isn't Working!....


The fan is good, was changed last year. I did see online about cleaning the outside unit with a hose. I tried to thuroughly wash it down enough a spray nozzle . But again, it if was all made of wood i could tell you how to fix it.
Last night, and yesterday it rained quite a bit, didn't stop, was very cold..
Can it be the capacitor? I changed that last year. Wasn't too hard to change. (I'm grasping at straws)

Actually, it's somewhat guesswork having little information, but 480 has the right approach. Clean the outside unit spraying from the inside out after flipping the disconnect. Damaged fins need straightening.

If shrubs have grown up close to the unit, or branches overhead cut them back.

Unless you feel like checking for duct leaks and sealing them up first, get an AC guy in before you have to buy a new unit.

On a sunny day the attic will be probably 30 or so degrees hotter than outside. If the ducting is run in the attic, it's more heat load for your AC to handle.

BTW, if it's high 90s outside and 70 in the house, you probably have good cooling. Check the temperature of the return air and cooling duct air closest to the heat exchanger.

Re: "Help! My AC Isn't Working!....


If you have a +/- 20 temp drop from where it's getting air input to where it's outputting then the system is working OK. (right before the evaporator and right after is where the measurement should be taken).

Re: "Help! My AC Isn't Working!....


One more WAG wild a guess: A coil freeze up = reset compressor?

Observe condensate drain water flow for it stopping /slowing while in operation

Make sure all parts are correctly sized for use with each other,

Fan CFM, A coil tonnage, Condenser tonnage, fan size, Kinked line?

Time delay working correctly between starts to allow compressor to "unload"?
