We have an Amana heater and central air thingy, we have called and spent hundreds of dollars for service calls, and they don't do or fix anytihing, basically, ill start with the heater, it runs but doesent blow out hot air, the central air is the same, no cold air just warm air. All frickin summer we have sweated our asses off with no air, stupid service techs. If someone could solve this problem that would be so awsome.
