The drain is clogged and there is water and crap fermenting in the bottom. I have a trane in the garage and it was also making a sweet nasty odor throught out the house. I turned the unit off in the house and I got a ladder and clean out the drain from the garage used Q-tips where the bleach did not get to and I put 1/2 cup of bleach in the drain. I let it sit for 10 minutes. Then I got the wet dry vac and went outside to where the drain is suppose to drain and I sucked out the drain. I repeated this step again in an hour. I changed all the filters and sprayed lysol in the return air. I turned the unit on again and I went to a motel for the night. Next morning the house was fresh and the garage was dry.
Air obviously
clean it, then spray it with air freshener.
A smell coming from a reverse cycle air conditioner may be a signal that the filter needs to be cleaned. A smell like engine exhaust might be present if the air conditioner motor is in need of repair.
This has much to do with how the air conditioner and the heater is vented. If the air conditioner draws its air from outside it could be picking up air / smell of smoke from the other family and then redistributing it into your home. A heater on the other had usually has a heater input vent within the house it is heating (it draws the interior air in and then heats it blowing it back out) as the air within the home will be significantly warmer than the exterior air.
small amount that lasts a minute or less condensation,no problem. large amount and/or a sweet smell, heater core is leaking.
It sounds like there is a leak inthe evaporator section of your air conditioner. If this continues, the air conditioner will no longer cool and you may have to replace several components of the system. The smell is that of atomized esther oil.
because you have too many dead babies in your air conditioner tank
An air conditioner should not smell like smoke when turned on (or when turned off). I would have to suspect that the electrical insulation is burning.
The first air conditioner for the home was available in 1928 when Willis Haviland Carrier developed the 'Weathermaker', an air conditioner for private home use.

If your air conditioner blows air but it's not cold air then you probably need freon in your air conditioner
there is a leak in the compressor...
