Reasons why the air conditioner is warmer

Reasons why the air conditioner is warmer
  • Lower refrigerant level.

Low refrigerant mainly occurs due to some leaks in the compressor. When the refrigerant is lower, the temperature and pressure are lower, too freezing the evaporator coil since the refrigerant works by evaporating liquids, hence causing the air around to freeze. Therefore, when the refrigerant is lower, the air conditioner tends to be warmer when it must be cold.

  • Dusty and stained condenser.

When dust accumulates in the condenser coils there will be no proper cooling in the house. Dusty condenser blocks the exchange of warm air and cold air in the air condenser. The dust in the condenser makes the air conditioner strain work making it warmer instead of being cold.

  • Issues with the ceiling fans.

Ceiling fans work by enabling the circulation and exchange of cold air in the upper part of the house and the warm air in the lower part of the house. Therefore, when the ceiling fans have a problem, they will not perform air circulation properly, making the air conditioner work only in the house hence failing to produce the cold air.

Faulty thermostats result from overusing the thermostats for a long period making their loose connection to the air conditioner. In addition, some thermostats are not compatible with the air conditioner since they are not programmable. Therefore, when the thermostat is not working well with the air conditioner, it forces the air conditioner to carry out all activities alone, which sometimes causes it to provide faulty results.
