Question about Air Conditioners

Very strong smell from air conditioner

I have a terrible sickly smell in the apartment, worse when the a/c is on (both for heating and cooling). It is a very strange but very distinctive smell. This has gone on for several months. We have checked all the other possible problems including plumbing but have drawn a blank.

You need to buy some airconditioning coil cleaner, which is a mild acid based solution and will not harm the aluminium fliliament or tubing in the evaporator. This should be done as a standard procedure at least once a year to sanitize the coil and remove bacteria and other baddies. Any normal cleaning liquid does not work. The coil cleaner penetrates the fins and makes a foam which pushes the dirt out of the coil. You will need to buy a small spray bottle and once you have done the cleaning part you can refil the bottle with clean water and spray the coil again. I am sure this will solve the smells.

Why does my heat pump smell strange i dont remember it doing that last year? have run it for ages the sickly smell wont go


Hi,
You probably have mold, algae, and mildew growing on the indoor coil...This can be treated by a UV Light installed at the coil or by spraying the coil with a coil cleaner with a algae inhibitor in it...

Heater smell when AC comes on...


The fan that blows the air blows through the heater coils before it blows through the A/C.As long as the heater doesn't come on, there is not much that can be done. ZCooking the attic room will be a problem because it is the heat rises thing, and on top(literally) of it all, the roof is radiating heat.

Brunt smell and sweating


Seems like your blower motor is burning up. Its the motor that blows cool air across the refrigeration coil. If it is a whole house ac unit, probably your main blower motor for the furnace. If you are getting sweat, that means the compressor is compressing the refrigerant, and you should not smell anything from the outdoor unit, only from the furnace. Hope this helps.

HEAT PUMP/AIR CONDITIONER UNIT SMELLS ONLY WHEN AIR IS ON


Not sure what the smell...smells like.  My guess is dirt or dust near the heating elements.  These will cause a burning smell.  Sometimes insects even get into the act..building webs.
You will have to clean that area out...sometimes a large blower or vac can dislodge the dust.
