If you mean it blows hot when the AC is on, if this is a 98 and you've never had the AC recharged, it's probably several years overdue. Of course, if you take it in, they WILL find other things "wrong" with it, and AC parts are very expensive, so be careful. A 98 Chevy is probably well on its way to the junk yard anyway, sad to say, so there might genuinely be other things wrong with your AC than a 5 dollar can of fluid can fix. If you have the heat setting to cold and hot air comes through the vents you might want to check to make sure you have enough coolant in your radiator and in the expansion tank if you have one. If you have an expansion tank that is the correct place to check it. There will be a mark on the side that says "Full Hot" and "full cold." If you check when the engine is still cold, it should have fluid up to the Full COld mark. If it's bone dry, well, there's your answer on the heat. Phil

Why is your air conditioner blowing cool air outside instead of warm air?

It is likely you have a heat pump. A type of air conditioning system which heats as well as cools. If there is cold air coming from the outdoor fan, you are in the heating mode. If you are calling for cooling at the thermostat, and there is cold air coming off the fan from the outdoor coil, there is a problem with likely the low voltage wiring.

Why does the air coming from your home air conditioner vents smell like stale smoke but not when your heater is on in a duplex where the other family smokes?

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.

A central air conditioner unit fan is blowing but no cold air is coming out of vents?

This is a partial answer. If the fan is blowing and air is coming out of the vent, but it's not cold, then I'm not sure what you can do. But, if the fan is blowing but no air of any temperature is coming out, then perhaps the evaporator coil has frozen. This can happen especially if the thermostat has been set for a temperature much cooler than the outside temperature. One way to check for this is to look to see if there is ice on the insulated copper line coming from the AC unit outside. To fix this problem, simply turn off the AC for a few hours. Turn your blower fan on using the manual override switch at the thermostat. This will help melt the ice on the evaporator coil. After several hours, check to see if you are getting air from the vents. Once you are, turn the AC back on--just not so low this time. (Or is it not so high?--Set the temperature in the range recommended by the manufacturer.)
