My 7 month old high-efficiency gas furnace recently broke down. I
awoke to hear the motor running, but the furnace wouldn't ignite. I
called a repairman.
The guy blew some water out of the air switch and told me that the
furnace had been installed wrong. The furnace was tilted away from the
drain. Somehow, this was causing condensation from the heat exchanger
to enter the air switch.
He didn't stop there.
He noted that the furnace was relighting before the cycle was
complete. He told me that the heat exchanger was in danger of
over-heating. His explanation:
when the furnace was installed, a rear filter cabinet was used. The
manual confirms that this particular furnace should have a bottom or
side filter cabinet. Since a rear FT was used, the air flow is being
restricted by a "squirrel cage???" in the back that blocks most of the
area in front of the filter. He went on the say that in addition to
flooded air-switches and broken heat-exchangers, this is gobbling up
lots of gas and also explains why my second floor doesn't receive much
Does this sound right??
I don't trust this guy. In addition to trying to avoid giving me a
receipt and asking that his check be made out to "CASH", he also won't
keep his promise to write up a description of the problem for my
realitor (she had the furnace replaced, and needs this before she is
willing to act).
Regardless, I don't know if he's lying about the furnace. Thanks in
advance for advice.
Furnace is: Crown Boiler model UCA 108 NH5R High-efficiency upflow
