heat pump cooling insufficient

Jun 16, 2009 6 Replies

I have a two-year old Lennox XP13 with a CBX32M blower coil set up in the down flow mode. I have two problems:



1) Insufficient cooling (air temp at the register yesterday was 73.6 deg with 74% humidity, o/s air temp about 88 deg.) A Lennox tech said the air temp at the register should be about 58-62 deg. BTW, on a 93 deg day the inside air temps will climb to about 83-84 deg.
2) During operation, I noticed condensation dripping on the blower housing and wiring. Any ideas? Thanks.

Sure;

Low refrigerant charge causing the coil to ice. You should expect approximately 18 - 22 deg differential from the indoor air temperature to supply temperature. If it's less than this, you need to have your neighborhood licensed, bonded, insured and trained HVACR technician stop by and check the charge, airflow, and insure the return duct is attached and sealed.

Good luck

and for those of you who havent figured it out by now..... The above statement is Stormys way of saying, "Gee folks. I really dont have the slightest clue on what his problem is. Maybe if I ask my boss he will know because I wouldnt even know how to tie my shoelaces unless my mommy tells me how. Bubba

So bubba boy, do you have a clue. Do you know how to tie your shoes?
