What happens when you change you system from cool to heat and it still blows out cool air?
The furnance is not coming on.

Heat Pump Troubleshooting . If the unit works in the heat mode, then the problem is usually located in the outdoor unit.
When you heat air, the air pressure rises and the particles expand.
Why does my 1998 s-10 2.2 can turn the heat control knob to cool but still blows out hot air the switch is good?
Check your vacuum lines, this is what opens and closes the ducts.. I had the same problem with mine. I just got it fixed a few days ago. The problem with mine was the compres…sor was leaking. Also i had the lines replaced, because they were sucked pretty much flat. To fix mine it was about $700. Wish i would have known that before I got it fixed.
Most likely. You just need add Freon. Real easy an cheap fix. If your Freon is full and your AC still not working. Probably gonna be your AC pump. That's not a cheap fix.
Try the thermostat, it may have accidentally been reset to a low temperature. Or the furnace (boiler) that supplies the heat may not be working. Or someone may have turned a v…alve to cut of the supply of heat to that part of the system. Withou tknowing whether you live in an apartment or your own house that's the best that I can suggest.
because it is broken
\nWhen it heats up it expands and rises, when it cools, it contracts and falls.
No, because it is a heating system, not a cooling system
so its not blowing at all anymore, as in no air at all? if tahts the case then how do you know its still cold. if it isn't blowing as well you may just need to change out your… filter, just like in a house all cars(most)have a air conditioner filter. if its not blowing anymore at all it sounds like your compressor or your whole dam motor went out, take it to shop.
when air(gas) is cooled(thermal energy is removed) its molecules slow down and it becomes a liquid(condensation) when air(gas) is heated(thermal energy is added) its molecule…s speed up, but it wont change into a different phase until gas is heated to a temperature above 10,000 C, which removes electrons from the atoms
Could be a clogged heater core. Just because it doesn't leak doesn't mean it's working right.
rear air unit has a air blending door solenoid, and is probably out. or broken making a clicking noise
If it`s a heat pump, they do that, heat is not instantaneous with them. If it`s a furnace the fan/limit switch or fan delay timer whichever you have, needs to be adjusted.
the amount of hot gas is not enough to change the form of all the liquids trap on it. By your question, I cannot tell of which component of the system you are talking about?… It sounds like you are talking about (for a heat pump system) the outdoor coil? If that is what you are talking about, I would say that you have either a failed circuit board (most machines reverse the flow of refrigerant and stop the outdoor fan during defrost cycle). I would say that your reversing valve is either not energizing or is defective or your circuit board.
Turn it on high
It gets colder. And the energy increases so the particles move further apart.
Why does the air bow cool air after you have change the thermostat and also had the coolant system flushed and It will not blow hot air?
My first suspect would be that you either bought a defective thermostat, or you did something wrong when you installed it. This is assuming that the problem didn't begin until… after you replaced the thermostat. If it was a problem which existed prior, I'd take a look at the heater core. It'll be in the same compartment in the duct system as your air conditioning evaporator, usually placed by the vent next to the passenger door. Yes, unfortunately this requires disassembling the dash. Before you go this route, you may want to ensure that there isn't any blockage in your upper and lower heater hoses.
