The A/C comes on and blows for a while, cool not cold. Then it seems to "fade," like it freezes up or something. We will turn it off for a while, then back on, and it blows again, pretty strong for a while, but in another little while, it's barely blowing and not cool. Can anyone advise???

Gas and Oil Home Heating Furnaces
Furnace Replacement

J

JEFF2761 on Oct 13, 2002

I removed an old, Coleman upflow forced air gas furnace from my residence and wish to replace it. I got a really good deal on a slightly used York/Luxaire downflow unit. The furnace is to be installed in the basement. Is it possible to install this unit by elevating it just enough to install the ductwork underneath and tying in to original ductwork? Would this affect the output airflow significantly? Would I be better off finding another upflow? Any suggestions/comments would be appreciated. The unit is a York/Luxaire model #PBKD-LD16N115A, S/N EADM024149. Thanks.

Furnace will not turn off

I have a forced hot air heating system. The furnace is a natural gas fired model. The problem is I can't turn the furnace off at the thermostat. I have to switch it off at the circuit breaker. I replaced the thermostat with an identical replacement and the problem still persists. What should I do now? :confused:
