[Guest guest]

does anyone know why my indoor humidity is highe than outside even

with ac running full blast??? we have replaced the systems within the

year and i have had service person after service person out. the

temperature outside have been hghs of 103 and lows of arpnd 80. at

the top of the heat, the outdoor humidity is around 20 per cent and

indoor goes up to 70 per cent. something is wrong.
