There's a debate within home decor about whether to use wall units for heating and air conditioning or a central air unit. The reasons range from cost and effectiveness to appearance and convenience. As you plan your building's climate control, consider a few factors that may change your opinion about what to install.

Wall Units For Area Control

Wall units have a limited reach, but can be very useful in large tenant buildings or if different residents have vastly different temperature preferences.

As wall units are installed with a vent and control unit in usually the same place, the resident of a specific space can change the temperature based on their own preferences without greatly affecting the comfort of others. There is of course a bit of a crossover as air from one room mixes with other rooms, but the change is often negligible.

The main problem with wall units is the initial investment. Unless you're heating or cooling a small apartment, you'll need multiple units to provide even, fair comfort. This cost can be offset by factoring the cost in rent for apartment buildings, but the cost can easily surpass a central air conditioning unit--a difference of $100 to $200 versus $500 to $1000 on average.

You'll need to decide if multiple units is worth the cost. Returning to the small apartment, a wall unit can be much more affordable if you only need one, and can be repaired or replaced relatively easily.

There is a style downside for many people. The basic wall units can be gaudy; a large rectangle with a flared vent may not be very attractive when it comes to home decor. If you'd rather hide the machinery and electronics used to keep your home running smoothly, a central air unit may be better.

Central Air Units For Bulk Climate Control

Central air is the go-to choice when you want most of a building to be the same general temperature. It may seem like a heavy up-front investment, but if your building is large enough, it can be cheaper than using multiple wall units to make the entire building comfortable.

There is a downside of everyone having to deal with the same temperature. Small conflicts over the best temperature or the silent suffering of a polite person with a different temperature preference can illustrate why central air isn't always the best. Depending on how much you're willing to invest, there are central air units that can offer multiple climate control zones for different temperatures in different areas.

Central air units can be large and overbearing, which may be a home decor disaster if not located out of sight with a bush or some sort of elegant cover. Contact a heating and air conditioning professional to plan not only your comfort, but your home design classiness when it comes to air conditioning and heat.
