You may have a leaking heater core but before you replace it check the heater hoses because sometimes coolant can pass under a loose hose clamp..........
If it smells sweet ,it is coolant, and the heater core has failed. If it smells electrical you have a wiring problem and need to remove whatever is necessary to find cause.
The air conditioner is low on refrigerant.
The most common thing will be that you have a leaking heater core...........
To properly vent a portable air conditioner, you need to use the included exhaust hose to vent hot air outside through a window or a vent. This helps the air conditioner work efficiently and keeps your room cool.
is your fan running in the correct direction? are any of your ducts blocked?
If it doesn't smell like smoke it could be comdensation off the evaporator core. You might have a clogged evap. case drain. If it is left unchecked it will start to smell moldy. If it is smoke, it usually be gray or black due to melting wires(also stink), afaulty blower bearings( would make noise).
AnswerWater vapor will sometimes exit your car's vents when hot humid air passes through the A/C cooling system too fast for the condensing moisture to form into water droplets. This can be resolved by selecting recycled air from inside the car, but the vapor is not harmful and usually doesn't last long.
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.
To properly vent a portable air conditioner using a venting hose, you should connect one end of the hose to the air conditioner and the other end to a window or a vent. This allows the hot air produced by the air conditioner to be expelled outside, while bringing in fresh air from outside to cool the room. Make sure the hose is securely connected and there are no obstructions blocking the airflow.
A microwave with an exhaust vent helps to remove smoke, steam, and odors from the kitchen while cooking. This can improve air quality, prevent lingering smells, and reduce the risk of setting off smoke alarms.
White smoke with the a/c on means that the a/c system is freezing up and you need to check the pressure switch........... White smoke with the a/c off means that you have a leaking heater core........
There is smoke coming from the chimney atop Petey's Pub. Stand on the cover there for a minute to partly block the smoke. Then the parrot can be found in the palm tree to the far right.
