If you'ray thinking about installing or replacing a medial air conditioner, you're probably alert that this is one of the most significant home improvements you can make in terms of comfort. On a hot, wet summer day, few amenities add to quality of life more than central air conditioner.
Air conditioning is also one of the most dear improvements you're likely to make, so IT pays to do your homework and choose wisely.
Types of Central Air Conditioners
This article is about whole-house air conditioning, non single-room units or heat pumps.
Unlike window, portable, or in-the-wall single room breeze conditioners, a central air conditioning distributes conditioned air throughout the house.
If you're non sure whether to buy individual board air conditioners or a central air conditioning, find the article Choosing Bifocal Beaver State Room AC, which compares the two. For info on single-room air conditioners, please see How to Buy a Window or Way Air conditioning.
American Samoa shown in the diagrams, a central air conditioning organization consists of a condenser unit of measurement, an air-handling unit with a blower (such as a unnatural-air furnace) and an evaporator whorl, and a system of ductwork for exchanging room air with chilled air.
The condenser typically sits outdoors, and the air handler with the evaporator is usually located in the basement, attic, or garage. The ductwork is routed through the basement operating theater garret and walls throughout the house.
The air conditioner uses infrigidation engineering science to stylish the air. (For more about how this works, see How a Central Air Conditioner Works.)
A heat pump is related to an air conditioner. It is essentially a medial air conditioning that can be reversed in winter to heat a house. If you'd like to know more, see Warmth Pumps Purchasing Usher.
A/C Size & Cost
If you've decided that a central AC unit is right for your home, information technology's metre to dig deeper into the particular size and type of unit, as well as its get-up-and-go efficiency, features, warranty, and more. These issues are discussed on a lower floor. For additional help oneself, imag:

Central Atomic number 89 Energy Efficiency
Because of today's countertenor be of energy, air conditioners are very high-priced to operate, and they consume to a higher degree their share of our precious Energy resources. Because of this, when choosing an air conditioner, the name of the game is efficiency—that is, an air conditioning's ability to commute vigour (electrical energy) into cooling in the most cost-effective way. You want maximum cooling system for minimum bucks.
One note about replacing an senescent arrangement: Cost sure to replace both the outside condensation unit and the indoor evaporator. If you just replace the condensing unit, prospective gains of a high-efficiency unit whitethorn equal lost.
The SEER Rating
To reduce wasted energy, the U.S. Department of Energy established minimum efficiency standards for air conditioners.
All AC unit is given an efficiency rating, known as a SEER— short for Seasonal Energy Efficiency Rating.
The SEER is listed on the yellow Energy Pass® label posted on apiece unit. It's very noteworthy to take these ratings. The higher the number the more efficient the whole and the less it will price to provide cooling.
During the gone decade, the minimum SEER rating needful of new units has continued to rise.
Though old free-flying conditioners whitethorn have a SEER as flat-growing as 6, models manufactured later on Jan, 2006, must consume a Visionary of leastwise 13. The all but underspent models have Prophesier ratings of 15 to 17. Just so you understand the congener scale, a SEER of 13 is 30% more efficient than a SEER of 10.
Vim-Saving Features
To achieve particularly high SEER ratings, air conditioners may consume any act of push-saving features. Bet for:
• Large coils for more efficient heat transfer
• A hotness rating (EER) greater than 11.6 and a thermal expansion valve. When the weather is hottest, this translates to treble-efficiency operation.
• A variable-speed cetacean to reduce electrical energy consumption, tailoring the usage to the penury
• A fan-only switch. This allows you to sour off the cooling just leave the winnow running game to circulate air for to a greater extent cancel, affordable cooling.
• An automatic delay fan switch, which keeps the buff happening long enough to utilize residual cool free-flying that remains aft the compressor turns off
• A filter indicator light that lets you know when the filter of necessity changing. This boosts efficiency aside ensuring strait-laced maintenance.
Other Features
Many luxuriously-efficiency products flux several of these features and add some of their own. Case in point: The York Prima Ultra features two compressors that work in tandem when high cooling capacity is required. The rest of the clock time, simply unrivaled of the compressors operates. These, combined with a variable-speeding motor, achieve a SEER paygrad of 16.7.
Programmable thermostats also help by offering precise control. For to a greater extent about these, see Thermostats Buying Guide.
What About Ultra-High Efficiency?
Do you need an ultra-high-efficiency air conditioner? Non necessarily.
Of course, for the sake of the environment—from energy usance to greenhouse-gas emissions—the high the efficiency the better.
But, in terms of dollars, the savings compared to the agio you leave earnings may not pencil out for you, particularly if you sleep in a climate that requires little cooling during the year or if your abode ISN't tightly insulated.
Connected the other paw, where an air conditioning must run oft during the year, a highly efficient model will compensate for itself in energy savings over a period of years.
Inner Ac Warranties
Gentle wind conditioning warranties are samara to ensuring that Ac systems will finish for many years.
In front purchasing central air conditioner, invite—and read—its warranty and be sure you understand the price and restrictions.
Air conditioner warranties can vary importantly from one maker to another. A warranty may cover most of the unit nether one set of terms or pass differing insurance coverage connected various parts of the air conditioner.
For instance, Whirlpool covers all parts of the mechanical and refrigeration systems (take out the air filter) for quintet years, including labor.
Common carrier covers the air-conditioning unit and authorized labor for repair or replacement for one year. With Attack aircraft carrier, the refrigeration components, including the compressor, condenser, evaporator, connecting tubing, and refrigeration heraldic bearing—including labor for repair or surrogate—are covered for years two through five under an extended warranty.
With umteen manufacturers, parts may be covered, but the labor for replacing much parts as the motorial, solenoid, relays, switches, and fans Crataegus oxycantha not be wrapped by warranty. Read the fine print.
And then in that respect is the "Limited Life-time Warranty." Amana, for object lesson, offers this and will cover the compressor of a high-efficiency air conditioner or heat heart for as long equally you own the planetary hous.
The bottom line with central air conditioner warranties is to read them carefully and realise what they do and do not cover.
Be wise that a warranty bequeath be avoid if the air conditioner is worked on by a non-lawful service person and that it does non cover standard maintenance, cleaning, or damage that is caused by neglecting maintenance.

Understanding Atomic number 89 Refrigerants
Refrigerants used in most air-conditioning systems manufactured until freshly can be real damaging to the Earthly concern's ozonosphere. Equipment that contains and operates using these refrigerants is being phased stunned internationally.
When purchasing new air conditioning arrangement, be sure to buy a topical product that utilizes refrigerants that do less damage to the environment.
How do refrigerants pass from AC equipment to the atmosphere? All refrigerant gasses are contained in an air conditioner's sealed system. The problem is that an aging sealed system may develop leaks and allow the refrigerant to escape. The release of these gasses besides occurs during service.
AC Refrigerants Beingness Phased Exterior
In 1987, an international agreement began a worldwide phase-extinct of ozone-depleting CFCs (chlorofluorocarbons), finally stopping production of AC equipment that uses them in 1996.
These were replaced by hydrochlorofluorocarbons (HCFCs). R-22 (also far-famed as Hydrochlorofluorocarbon-22 or, more normally "Freon") has been the favored refrigerating for residential air-conditioning and heat pump systems. This is less prejudicial to the Earth's ozone stratum, but still is an ozone-destroying greenhouse gas and, during its manufacture, produces HFC-23, which contributes significantly to global warming.
This is a problem, sol the manufacture and import of R-22 AC equipment was phased out by the EPA in 2010 below the Clean Publicize Act. The manufacturer of the refrigerating R-22 was reduced away 75%, will be further minimized by 90% in 2022, and was scheduled to be stopped by 2022. Every bit a result, R-22 is decent increasingly expensive.
If you pauperism to have R-22 recharged in existent equipment, be sure to get a price quotation mark first and get word whether the quote includes service, which typically costs about $115. Don't beryllium surprised if the gas costs $100 per Ezra Pound or more. This toll is only going to go up. (Equipment typically only needs to be recharged if IT's leaking—first and foremost, get the leak fixed!)
Alternatives to R-22 Refrigerant
Today, manufacturers of residential air conditioner systems offer Alternating current equipment that uses ozone-friendly refrigerants. For servicing existing equipment, R-22 is still available and will continue to be available for 10 age or more.
The EPA has reviewed a variety of substitutes for R-22. You rear attend these on these alternatives to R-22 on the EPA website.
A popular substitute for R-22 is R-410A, a go of hydrofluorocarbons (HFCs). It is manufactured and sold low various trade names, including Puron®, Forane® 410A, GENETRON AZ-20®, and SUVA 410A. It does not deplete the ozonosphere just, like R-22, its manufacturer does contribute to global calefacient. R-407C, another acceptable substitute for R-22, is used in both European residential air conditioners.
