Air conditioner is blowing hot air, it was installed 1995 , the top switch option is CONT FAN AUTO and bottom switch is HEAT OFF COOL and on the right is a dial from 10-30
First of all, what do you mean by hot air? DO YOU REALLY MEAN ROOM TEMERATURE AIR THAT JUST DOES NOT FEEL COLD? If this is a heat pump system, we need to look at it differently than if it is a gas or oil fired heater. Next, the thermostat control that says "cont.fan auto"----- this actually means FAN switch to be in AUTOMATIC RUN or CONTINUOUS RUN mode. Leave it in auto mode and forget that it is there; this little switch confuses a lot of people. The dial that says 10-30 is centegrade temperature that translates to 50-87 degrees farenheit. In order to get air conditioned (cold) air, you must have thermostat fan switch on auto, the heat/off/cool switch on cool, and the 10-30 dial on 20 or 21 (68-70 f.) assuming the room temp is at least 72 degrees f. or higher. If you still do not get cold air, then there is a problem with the cooling circulation system which can be tripped circuit breaker to outside compressor unit, loss of freon refrigerant, bad control such as relay or reversing valve in outside unit, stuck heat sequencers or heat element relay that are giving you heat at the same time giving cold if it is a heatpump system. You will need a skilled service person to determine these problems. Goodluck, Macgivor
