Hi,
Unfortunately no....but did they try a new capacitor first??? I would have them replace that first and then if that don't work the compressor will have to be replaced..
Here is a tip about troubleshooting your air conditioner... There are many things that can cause your air conditioner not to cool…
Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.
Hi, depending on the size like a 5ufx35 or 40 uf x either 370 volts or 440 volts cost around $14.00 give or take. The last I bought at Grangers supply, a 5uf 370 volt x 40 uf was exactly $ 14.80. Not that expensive. They go up the higher the volts as 440 and mirofarads. Best to you, Shastalaker7 A/C and Heating Contractor

do you own a multi meter? do you know how to use one? if not call some one.
does the unit keep running outside if you turn off the furnace power switch. if it keeps running it the contactor in the condensing unit. if it shuts off it is your t-stat.
Sounds like a classic case of a burnt/pitted compressor contactor. The contacts can get pitted and sometimes burnt. This can cause them to stick and the unit will not shut off unless you shut off the circuit breaker. When you shut off the circuit breaker, the contacts would have cooled down which could have led to the problem you are now experiencing......will not come on. Open up the electrical box. Look near the bottom for a brown or black part with the wires from your circuit breaker wired directly to it. This is your contactor. In the center is the piece that moves up and down to allow the electricity to go to your compressor and fan motor when there is a call for cooling. Check to see if it looks burnt or otherwise damaged.
Lets test the t-stat. Take the cover off the stat locate the terminals R & W take a small piece of wire and holding the wire jump across the two R & W terminals. Does the furnace start up immediately? or does the same problem exist? Sometimes in diagnostics you have to start to eliminate the problems one by one. ken
