Whole house air conditioners · Heat pump · MRCOOL DIY Universal 5 Ton. By comparison, central air conditioning is a major breakthrough in terms of comfort, silence and, above all, comfort. With the right size and installation, a split system (one with indoor and outdoor equipment) can keep an entire house cool on the hottest days and do so much more efficiently than a battalion of window units. Air conditioners dehumidify air to improve comfort.
However, in extremely humid climates, when outside temperatures are moderate or in cases where the air conditioner is oversized, the air may not reach a humidity low enough to reach a comfortable level. In those cases, homeowners can reduce the thermostat settings or use a dehumidifier. But in both cases, this will increase energy use, both for the dehumidifier itself and because the air conditioner will require more energy to cool the house. If you have a central air system in your home, set the fan to automatic mode.
In other words, do not use the central fan of the system to provide air circulation; use circulating fans in individual rooms. A central air conditioner is a split system unit or a packaged unit. In a split system central air conditioner, an outer cabinet contains the outdoor heat exchanger, the fan and the compressor, and an inner cabinet contains the indoor heat exchanger and the fan. In many split system air conditioners, the inner cabinet may contain an oven or the indoor heat exchanger of a heat pump.
If your home already has a boiler but doesn't have air conditioning, a split system may be the most economical central air conditioner to install. In a packaged central air conditioner, the heat exchangers, the compressor, the fan and the fan are all located in a cabinet, which is usually placed on a roof or on a concrete slab next to the foundation of the house. This type of air conditioner is also used in small commercial buildings. The supply and return ducts come from the inside through the outer wall or roof of the house to connect to the packaged air conditioner.
Packaged air conditioners typically include electric heating coils or a natural gas oven. This combination of air conditioning and central heating eliminates the need for a separate oven. If your air conditioner is properly installed or if significant installation problems are found and fixed, it should work efficiently for years with only minor routine maintenance. However, many air conditioners are not properly installed.
As an unfortunate result, modern energy-efficient air conditioners can perform almost as poorly as older inefficient models. Central air conditioners are more efficient than room air conditioners. Plus, they're out of the way, quiet and comfortable to operate. To save energy and money, you should try to buy an energy-efficient air conditioner and reduce the energy use of your central air conditioner.
In an average-sized household, air conditioning consumes more than 2,000 kilowatt-hours of electricity per year, causing power plants to emit about 3,500 pounds of carbon dioxide and 31 pounds of sulfur dioxide. If you're considering adding central air conditioning to your home, the deciding factor may be the need for ducts. The most efficient air conditioners use 30 to 50% less energy to produce the same amount of cooling than air conditioners manufactured in the mid-1970s. Even if your air conditioner is only 10 years old, you can save 20 to 40% of your cooling energy costs by replacing it with a newer, more efficient model.
Proper size and installation are key elements in determining air conditioning efficiency. A unit that is too large will not properly remove moisture. A unit that is too small will not be able to reach a comfortable temperature on the hottest days. Improper unit location, lack of insulation, and improper duct installation can greatly decrease efficiency.
Regulations don't require you to replace your existing central air conditioning units, and replacement parts and services should continue to be available for your home systems. The lifespan of a central air conditioner is about 15 to 20 years. Manufacturers generally continue to support existing equipment by providing replacement parts and complying with maintenance contracts once the new standard comes into effect.

Energy Efficiency Office %26 Renewable EnergyForestal Building 1000 Independence Avenue, SW Washington, DC 20585.CENTRAL AIR Central air conditioning is the most popular type of cooling system in the United States. More than 75 percent of homes with a cooling system use central air, according to the latest data from the U.S. Energy Information Administration. It's definitely possible to negotiate the costs of installing your air conditioner with your contractor.
The main factors for most homeowners will be the total cost of installing the best brands of air conditioning, the lifespan of the air conditioning unit, the warranties offered, energy efficiency (SEER ratings) and the unit size you need for the square feet (TONS) of your house to cool your home efficiently. When installing a new central air conditioning unit, major air conditioner brands and the associated costs can be an important decision factor. Whether you're planning to do a deep cleaning of window air conditioning systems and installing the central air conditioner from scratch, or if you're investing in an HVAC upgrade, you'll find a lot of useful information to help you make smart choices. The Bryant air conditioner brand is another great brand to consider when looking at HVAC replacement options.
Carrier is also known for having highly qualified installers who are specifically trained in how to install a Carrier air conditioner. American Standard air conditioners are one of the best central air conditioning brands in the business. Affiliation with Air Conditioning Contractors of America is an advantage; an ACCA certificate in residential HVAC design is even better. Reequipping older apartments with central air means installing a condenser outside the house, a fan and coil system inside, and ducts to distribute the cooled air.
However, as recently as 1993, only 68 percent of homes in the United States had any refrigeration equipment, whether it was window air conditioners or central air conditioning systems. The special air controller that generates this air at high velocity dehumidifies and mixes the air in the room so effectively that return ducts are not needed in all rooms; a single return located in the center is sufficient. Even if you're willing to give up a closet to install a central air system in your pre-war apartment, your building may not allow you to place a condenser on the ceiling. .
