Besides the cold air coming through ducts instead of visible hanging wall units, what’s the deal with Central Air Conditioning?  Are they good for anything besides their reputation for running up electricity bills?

Actually, Central Air Conditioners are rated higher in terms of energy efficiency than Wall Unit Air Conditioners because Central Air’s greater size and greater installed technology have the ability to cool greater volumes while consuming less energy.

However, if only one or two rooms need cooling, the Wall Units make more financial sense.  But for cooling many rooms and open spaces, Central Air will use less energy than running many Wall Units at the same time.

Central Air Conditioning will keep the temperature more consistent and balanced throughout your entire place.  Set the temperature you desire and thermostats will automatically regulate the Central Air system for you.

On the other hand, Wall Units will cool only the area their fixed to.  Temperatures need to be manually adjusted and trying to match them in different rooms on different Wall Units requires constant adjustment, that usually leaves you with cold spots and hot spots.

On modern Central Air systems, zones can be created to set different temperatures in different zones.  So while the air is lowered in the kitchen during the night, you can still enjoy a chilly bedroom sleeping under the covers.


Air Quality

As mentioned, the greater size of Central Air accommodates more technology, like better air filtration systems that filter out pollutants and allergens, and increase the quality of the air you breathe.

Another byproduct of air conditioning is its dehumidifying affect.  The more air that passes through the air conditioner, the more it dehumidifies the room.

The steady and continuous flow of Central Air dehumidifies your room better than the spontaneous bursts of air from Wall Units, that although may cool your room just fine, doesn’t draw enough moisture out and can leave your room feeling damp and clammy.



Air conditioners need to be regularly maintained, its filters washed and duct work checked.  When your Wall Unit becomes clogged with dust, air isn’t as cold and the unit will start leaking water, soaking the furniture below it unexpectedly.

In Central Air, if one component goes wrong, the whole system is down.  Since it’s centrally located though, you won’t have repair and maintenance crews leaving footprints in your place as with Wall Units.  Although spare parts and maintenance for Central Air will cost more, if you’re living in a condominium, those costs are spread out and shared.

Central Air Conditioning is quieter than Wall Units.  If you live in a condominium, the large compressors for the Central Air are usually placed on rooftops, a good way out of earshot.  Whereas the compressors for Wall Units are just outside your window.

Though you’ll hardly forget you’re louder Wall Unit is running, with quieter Central Air, people tend to not realize they’re on and may forget to turn them off before going outside.


So who would consider Central Air in a condominium?

Families with children or couples living in spacious multiple room condominiums with some stay home bodies, will benefit from the uniform cooling, air filtration and quieter properties of Central Air.  On the other hand if you’re just a person who wants to set it-and-forget it, the Central Air system will do you good.
