Chemical type odor from the HVAC
Frost and thaw on evaporator, see conditions below.
Customers may come in complaining of a "chemical" type of odor coming from the vents when the
air conditioning is on. It is most noticeable during a restart after a stop/start
event. It may vary in
severity based on the customer's sensitivity
.
Follow the system function tests and diagnostics inSI.
If no issue is found, advise the customer that the following settings ma
y help minimize their issue:
Operate system in outside air (primarily)
Set the temperature setting slightly higher (64 F +)
Set the fan speed slightly higher (3 +)
Running the air conditioning at max cold, with low fanspeed in air recirculation mode will cause the
condition to be worse.
At this time, there isn't a repair to completelyeliminate the condition.
