Heater smell coming from AC

Jennifer

A couple of weeks ago, my husband and I noticed that the ac started
blowing hot air and it smelled like the heater was being turned on.
You know that smell when you first trun your heater on? So well
called and AC repair man and he came out and said that the coil was
clogged and that caused the rise in temp. So he unclogged the coils.
Well that stopped the hot air from blowing out, but about every 10
minutes whe the AC kicks on it blows air that smells like the heater
is on. The air coming out of the vents is cold, but it smells really
bad. What could be wrong?

Thanks for your help

A dead mouse? Your missing cat? Why were your coils clogged, no air
filter?

Why were your coils clogged, no air filter?

No we change the air filter once a month. That is another funny
thing, because the AC Filter is never dirty. I mean not a drop of
dust on the filter. We have two cats and live in Florida, so it seems
to me that the filter should be dirty, but it never is.

problem

I had that moldy smell in the spring and early summer , no dss or lamp
shit , I had a humid basement causing a bit of mold even though my
ducts were cleaned twice . by pros . 750.00 for 1200 sq ..........1900
sq inc total sq ft .... my findings were to install a dehumidifier for
the basement , add return and supply to basement for circulation....
the real difference was keeping basement humidity down, AC guys said
returns and vents are all you need , but in real life basements can be
moisture pits. no amount of vents and returns could flow enough
air ,.,., ...... stop leaks , and try a dehumidifier this
summer ,, drain with hose to drain, or sump pit.....spray black areas or
moisture laden areas with beach , they will lighten in color if mold is
the problem ,. you say your filter is clean when you chnage it.
....maybe the previous owner never did ,,,,,, my friend a steel mill
mechanic had this overlooked ,,,, his equipment was cloged shut....the
smell ?? of what?? thats your decision........ Usually mold......
But i have lost a few bats and rodents [ dissapear over the years ]
and can say my problem was mold or mildew...If your ducts run in a
crawlspace your odds increase for this... get a new service man , and
check and adjust everything , from top to bottom in and out...

Sounds like a classic case of DSS..or Dirty Sock Syndrome..
Any competent, HVAC man can remove that from the system, as long as its not
in any way effected the duct work, and then, it can be repaired...

IF this turns out to be the case, you will seriously want to consider
looking into the UV-C band of lamps.
