Air Conditioners

The content of the article:

When choosing an air conditioner to buy, it’s best to first evaluate your options on the basis of needed capacity and best fit. Before you shop, find out the square footage of the room the needs to be cooled. If you are getting a lightweight or windows unit, measure the window opening.

While there ere are many notable distinctions between brands, unless you are loyal to one in particular, most offer the same basic products, so you should go into your search staying open to the many possibilities. Price is mainly a function of the style and BTU power, although efficiency is rapidly becoming an important distinguishing feature as well.

Air Conditioner Types

You can find essentially 4 types of home or light commercial ac units: easily transportable standalone products, thru-wall and in-window room products, ductless mini and multi divide systems and packed central air conditioning equipment.

Each one of these types can be further subdivided such as BTU result and functional features, but, apart from some central air systems, each is driven by either 120- or 240-volt electricity.

Lightweight Products

Portable ac units are standalone products that always feature durable casters for easy flexibility. Their power result runs from 5,000 to about 12,000 BTUs each hour and they connect in to a standard wall shop.

The latest models of from the many makers feature a whole range of features, from remote control and digital display to 4-in-1, cooling/fan-only/dehumidification/heating capability.

Portable air conditioners are space saving and energy efficient. Programmable timers and energy saving modes combine compressor use with fan-only settings to maintain cool temperatures while conserving power. This type of air conditioner is ideal for small to medium-size areas or to complement a central system.

They are unvented ac units, so look for the models that use evaporative technology and also have no drinking water bucket to unfilled.

Wall structure/Window Systems

Thru-wall and in-window ac units set up, as their brands suggest, either into an starting in a wall structure or in a normal screen. In both situations they might need a sleeve or framework for installation. Screen units have a tendency to be a little more portable, specially when outfitted with slide-out framework. This allows them to be installed and removed easily.

Both types vent to the outdoors and provide a range of chilling and heating options, from 5,000 BTU to 36,000 BTU output. Like their lightweight counterparts, numerous operational features are available with wall and window devices including remote control, multiple chilling and fan settings, dehumidification mode and built-in warmth pump for use during the chilly season.

Certain models are Energy Celebrity rated, and many devices come with a high energy efficiency percentage (EER). Room wall and window devices are capable of cooling spaces as small as 150 square ft all the way up to large rooms or whole floors, depending on the BTU output. Many models require 120-volt power, but some heftier devices that attract more amps need 240-volt hardwired power.

Other features commonly found on these devices are auto restart, removable and washable filter and anti-corrosion outer grilles and fins.

Mini and Multi Break up Systems

Possibly the most energy conserving of all ac units, mini and multi divide systems merge components of central air with room systems to provide wide-reaching air conditioning while providing you complete thermostatic control of specific cooling areas. These systems are ductless, signifying they don’t need the circulate cool air through a home’s existing network of the heating system ducts like central systems do.

Divide systems contain 3 main components: a patio condenser/compressor device that is set to a well balanced surface, an inside wall-mounted unit which has the environment handler and an one-touch handy remote control. The outdoor device means that the air conditioning equipment functions almost silently indoors. Because air is not channeled to the complete house from a central location, you can control where it comes out.

Mini systems feature a single wall-mounted unit generating 9,000 BTUs or higher, while a multi system features up to 4 devices that generate a total of up to 42,000 BTUs divided between them. With multiple devices each independently controlled, you never have to waste energy in zones not currently in use. For this reason, split systems give you the most flexibility in terms of chilling, while still providing a considerable amount of output. They are also much easier to install than a central air system.

Central Air Systems

Most commonly packaged one outdoor container, central air systems pipe refrigerant-cooled air to your home’s existing network of heating ducts and distribute it throughout. New central air conditioners are designed to be energy efficient and must have a minimum SEER rating of 13, although more efficient units are widely available.

Central units are ideal for large homes in warm climates that require frequent and consistent cooling. They can be expensive to purchase and require a somewhat major installation, but they will last for a generation if well taken care of.


air conditioning equipment manufacturers range between household titles to less well-known brands that non-etheless make high-quality products. A number of the bigger brands that produce a number of types of ac units include General Electric, Mitsubishi, Sanyo, Frigidaire, Kenmore, Amana, Maytag, Carrier and Whirlpool. Among the less well-known air conditioning equipment brands you find Fedders, Goodman, Haier, Soleus, Sunpentown, Friedrich, LG, Speed Air, Napoleon, Amcor, Danby, OceanAire and Whynter.
