Carrier Comfort 13 Puron model 24ACA3 / FV4NB006 installed 3/18/08 no longer cooling. Carrier AC1-100 Thermostat checked per manual - all default settings intact. Test override did not turn unit on though. All systems turned "on" - circuit breaker "on". Noticed last night that room temperature was rising so we turned target temperature down. Usually room temperature and target temperature are within a 1 or 2 degree swing. System did come on & cool once last night. Today though system is not coming on at all. What else can I do?

Verify 24 volts at the low voltage transformer inside the air handler.
If it is OK, jump out the red/green and yellow thermostat wires. If everything comes on, replace the thermostat.

The only important part is before the last A. It gets broken into two parts, xxABA, and *** (where x is any number) 24ABA:
24A = A/C (24H would be heat pump)
B= Base series, C would be Comfort, P would be Performance and N would
be Infinity. (B, C, P, N in that order gives you more bells and
whistles)
3rd letter = A (puron) or B (R22). 342:
First number = SEER 3 = 13, 6 = 16, 1 = 21.
42 = btu in thousands (18-60)
This means that your unit is a 13 SEER, 42,000 BTU base-model Air Conditioner which uses Puron (R410 refrigerant).
Yes, by turning it off this resets the unit. Just turn it back on and if there are no other problems, it will run. Shastalaker7 A/C, & Heating Contractor
Tell him you already had it done. lol. Unless you misunderstood what he told you no! You don't need to replace the Refrigerant weather it's Puron or Freon. It doesn't wear out. Ever. If your system develops a leak and you loose the Refrigerant it will have to be replaced but you will know you lost it because the system won't cool and heat like it's supposed to. I would report the installer to the better business bureau.
the e2 error on your thermostat is a problem with the return temp sensor on your system, the only thing you can really do is call a company and replace it, you can't bypass it or remove it cause the system wont run properly
If the upstairs is working and the down stairs is not,You only need to have one unit checked,Don't assume it just needs puron(If it does,You have a leak,which cost more to locate and repair than some other likely causes)This is not something you can do yourself and is illegal if you are not EPA certified.to get a fair price would depend on your geographic location and the best way would be to call around to some local heating and air companies and ask how much a service call is.(That only tells you the price for them to came and see what the problem is,They will not be able to quote a price until they know what must be done to make the repairs.

I have seen this before when there is an obstruction in the evaporator coil metering device. This causes the compressor to struggle moving the Puron. After the Puron has been recovered make sure that they do a complete check of the metering device and check for other obstructions. When they are done checking they must do a proper vacuum to remove any non condensables like water condensation. Finally they should have installed both a liquid and suction filter dryer to reduce any dirt and stuff. The only other options are unlikely, as we will assume that the last company installed the correct (new) compressor and that they did not do a hack job.
On a happier note, the compressor should still be under the 10 year parts warranty!
