if it pulls for outdoors then my question is WHY? someone was explaining to me how a heat pump works nd it just doesnt make sence to take air from the cold outdoors and extract heat from it or when its hot out to pull HOT air from outside and try to cool it. please explain how a heat-pump works and why outdoor air is used.

p.s. the reason i am asking is because my a/c becomes less effective the colder it is outside, so when its 30 degrees it is only 65 degrees or so insiide even if i have it set for 75, i was told it was because of how a "heatpump" worked.

If it's a heat pump, it does work harder as the O.A.T.
gets lower. It pulls HEAT, not hot air. As it gets colder outside,
it has to pull harder to get heat out of the colder air.
It sounds like you're either freezing the coil, the system
needs service, or it was improperly designed and it can't meet its load.
If you've got trouble at 30 Deg. you're in for a 'happy` winter.
Most residential systems depend on air leakage to
supply outside air. Modern 'tight` houses may have a small outside air intake, but even then most of the air is recycled.

Most forced air heating systems draw and reheat inside air. I just had a new high efficiency heater put in a couple of years ago but the duct system is the same system that has been here since the sixty's and the return air draws from inside air only.

Most Heating Systems recycle the air inside the house. If you have Central Heating you should have something that looks like a large vent near your furnace in the wall or ceiling. This is your return and where the air is brought into your system.

A heat pump works differently than a central heat furnace. A heat pump works like the defroster in your car. The defroster in your car works off of the a/c compressor. So does a heat pump. When your the cooling side of your compressor is working it pulls heat from your house. This results in heat in the condenser and high pressure side of the compressor. In winter or cool weather the air is passed over the condenser instead of of the cooling coils. The downside to this is that in extremely cold weather the condenser coils are not going to be as hot. A central furnace heats the air inside your house by passing the air over gas flames inside chambers or electric heating elements.

No it does not pull air from the outside,look where you change your furnace filter, that is where it draws air from ,your furnace filters out the air intake so it doesnt recycle dust and pollens in the are throught out your house ,thats why its important to change out every month or 3 months depending on the merv rating.

It does not bring air in from the outside. For complete details about how they operate check out the heat pump page at my source.
