Heating Unit

If you are not getting hot air from your York gas furnace, check for the burners are ignited. Actually, igniters are small sparking devices that are used to light off the gas. These igniters are controlled by the thermostat. Ensure that the burners are fully functional with adequate flame heating the heat exchanger. The heat exchanger is a large, open area box that warms the air.

Also, see whether evaporator and compressor fans are functioning normally to blow out warm air and pull in cold air. If any of the components have malfunctioned in the furnace, it reduces or stops warn air circulation.

Air Conditioner

York air conditioners and furnaces have the almost same type of components including fans, air exchangers, etc. But, instead of burners in the furnaces, AC uses a compressor and evaporator coils for reducing the temperature of a coolant. So, when your unit not circulating cold air, you need to check the coolant level to confirm that your air conditioning unit has a sufficient amount of charge.

After that, check if there is a buildup of dust or dirt on the coils. Make sure always the coils are free of dirt or anything. If these coils are dirty, it can reduce the ability of the air conditioner in lowering the air temperature. Moreover, the fans must be working properly to move the cool air away from the AC.
