CHOOSING OR UPGRADING YOUR CENTRAL AIR CONDITIONER
Central air conditioners are more efficient than room air conditioners.
In addition, they are out of the way, quiet, and convenient to operate.
To save energy and money, you should try to buy an energy-efficient air conditioner and reduce your central air conditioners energy use.
In an average air-conditioned home, 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 are considering adding central air conditioning to your home, the work.
IF YOU HAVE AN OLDER CENTRAL AIR CONDITIONER,
YOU MIGHT CHOOSE TO REPLACE THE OUTDOOR COMPRESSOR WITH A MODERN, HIGH-EFFICIENCY UNIT. IF YOU DO SO, CONTACT NRG HEATING & AIR CONDITIONING INC. TO ASSURE THAT THE NEW COMPRESSOR IS PROPERLY MATCHED TO THE INDOOR UNIT. HOWEVER,
considering recent changes in refrigerants and air conditioning designs, it might be wiser to replace the entire system.
Today’s best air conditioners use 30% to 50% less energy to produce the same amount of cooling as air conditioners made in the mid 1970s. Even if your air conditioner is only 10 years old, you may save 20% to 40% of your cooling energy costs by replacing it with a newer, more efficient model. Proper sizing and installation are key elements in determining air conditioner efficiency. Too large a unit will not adequately remove humidity. Too small a unit will not be able to attain a comfortable temperature on the hottest days. Improper unit location, lack of insulation, and improper duct installation can greatly diminish efficiency.
WHEN BUYING AN AIR CONDITIONER,
look for a model with a high efficiency.
Central air conditioners according to their seasonal energy efficiency ratio (SEER).
the relative amount of energy needed to provide a specific cooling output
. Many older systems have SEER ratings of 6 or less.
The minimum SEER allowed today is 13.
Look for the ENERGY STAR® label for central air conditioners with SEER ratings of 13 or greater, but consider using air conditioning equipment with higher SEER ratings for greater savings.
New residential central air conditioner standards went into effect on January 23, 2006. Air conditioners manufactured after January 26, 2006 must achieve a SEER of 13 or higher. SEER 13 is 30% more efficient than the previous minimum SEER of 10. standard applies only to appliances manufactured after January 23, 2006. Equipment with a rating less than SEER 13 manufactured before this date may still be sold and installed.
THE AVERAGE HOMEOWNER
will remain unaffected by this standard change for some time to come. The standards do not require you to change your existing central air conditioning units, and replacement parts and services should still be available for your home’s systems. The “lifespan” of a central air conditioner is about 15 to 20 years. Manufacturers typically continue to support existing equipment by making replacement parts available and honoring maintenance contracts after new standard goes into effect.
OTHER FEATURES TO LOOK FOR WHEN BUYING AN AIR CONDITIONER INCLUDE :
- A thermal expansion valve and a high-temperature rating (EER) greater than 11.6, for high-efficiency operation when the weather is at its hottest
- A variable speed air handler for new ventilation systems
- A unit that operates quietly
- A fan-only switch, so you can use the unit for nighttime ventilation to substantially reduce air-conditioning costs
- A filter check light to remind you to check the filter after a predetermined number of operating hours
- An automatic delay fan switch to turn off the fan a few minutes after the compressor turns off.
TYPES OF AIR CONDITIONING UNITS TO CONSIDER
HVAC is an acronym for Heating Ventilation and Air Conditioning. Basic residential HVAC systems consist of 3 varying types:
1. first kind, which is also the most common, is called the Split System:
- HVAC system consists of an Air Conditioning Condenser (the unit sits outside, usually on the side or back of the home or on the roof), the Evaporator Coil, the Furnace, and the Air Duct System.
- condenser compresses the refrigerant, transforming from a gas to a liquid state, and is transferred to the Evaporator Coil.
- air then passes over the Evaporator Coil, where it is . The Furnace uses natural gas via burners located in the furnace to heat the home
- Evaporator Coil is always situated with the Furnace, whether horizontally in the attic or installed as an up flow/down flow, which would be in closet or the garage.
- As the air is by the Furnace through a return air grill, it then blows over the Evaporator Coil, which cools it, and then into the ducts, which blows the air into the home.
- air travels throughout the home via a flexible polyurethane Air Duct System.
2. ANOTHER TYPE OF HVAC SYSTEM IS THE PACKAGED UNIT:
- Because HVAC system is usually situated on top of the roof and contains both the heating and cooling components in one piece of equipment (hence the “packaged” name).
- It uses both natural gas and electricity
- air in the system, heated or cooled depending upon desired setting, and pushed down into air duct system.
3. The 3rdtype of HVAC system is the Heat Pump System
- This HVAC system runs solely on electricity and heat and cools via the refrigerant in the system.
- system consists of a Heat Pump Condenser (which usually sits on the side or back of the home or on the roof) and an Air Handler.
- Heat Pump Condenser uses refrigerant to heat and cool the air (through reversing valves), which is sent into the Air Handler.
- when Air Handler pushes air into the Air Duct System with blower motor.
