Energy Efficient Cooling Systems

In the United States, the efficiency of air conditioners is usually rated by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, the more energy efficient the system will be. The United States now requires that all new residential systems have a minimum SEER rating of 13 or higher.

More efficient air conditioning systems will provide substantial savings on your utility bills. By upgrading from a 10 SEER to a 16 SEER, for example, the power consumption is reduced by 30%. This can result in an energy savings of up to $300 per year, depending on the usage rate and the cost of electricity. In many cases, the lifetime energy savings will surpass the higher initial cost of a high-efficiency unit.

Central Air Systems and Air Conditioners

An air conditioner changes the temperature, humidity or general quality of the air. It makes your home cooler by drawing heat energy out of the house and transferring the heat to the outdoors. Then, the AC replaces the air inside your home with cooler air. A central air system uses ducts to distribute cooled or dehumidified air to an entire home. The most common central cooling system is a split system. This system features an outdoor cabinet containing a condenser coil and compressor. It also has an indoor evaporator coil, usually installed in conjunction with your furnace or air handler. The compressor pumps refrigerant through the system.

Once warm air inside your home blows across the indoor evaporator coil, its heat energy transfers to the refrigerant inside the coil. That transfer “cools” the air. The refrigerant is pumped back to the compressor where the cycle begins again. The heat absorbed by the refrigerant is moved outside your home while cooled air is blown inside. Moisture that contributes to humidity is also condensed out of the air.

Your cooling system is usually combined with your central heating system because they share the same ductwork for distributing conditioned air throughout your home

Mini-Split Systems

Installing central air conditioning in a home that does not have air ducts can be difficult. A Mini-Split HVAC system provides a unique solution to bring central air conditioning into homes or rooms without ducts. By piping refrigerant to individual coils within air handlers mounted throughout a home, mini-splits do not require ductwork like central air conditioning systems. Mini-split systems combine the flexibility of room air conditioners with the whole-house cooling of central systems. Although some systems provide heating and cooling, ductless mini-split heat pumps are usually installed primarily for cooling.

Zoned Systems

Zoning lets you choose the temperature you want, where and when you want it. You might want to keep areas where you relax, such as the living room and family room, a bit warmer. But you might want bedrooms, a recreation room and your kitchen a bit cooler. Zoning your system enhances your comfort and reduces your energy costs by as much as 30%.

High-Velocity AC Systems

Many owners of older homes without cooling systems or finished basements would like to add central air conditioning but are daunted by the cost and difficulty of installing ductwork. Standard ductwork may require removing large sections of walls, floors or ceilings. Adding a high-velocity cooling system minimizes the alterations by using small diameter ducts, rather than standard ducts. The smaller ducts can be threaded through floor, ceiling, and wall cavities more easily. These high-velocity systems operate quietly and improve dehumidification. They are more energy-efficient than standard air-delivery duct systems.
