At times, air conditioning units do turn on, but they stop blowing cold air. There isn’t one but several reasons behind this problem.
Like, the air filter might be clogged with dirt, dust, pet danders and other impurities. Or, there may be power or thermostat issues, because of which your AC unit isn’t blowing cold air.
Low refrigerant levels, ice buildup and dirty compressor, could also be the reason why your air conditioner is malfunctioning.
