How The Central Cooling System Works
Central Cooling air units are split systems: an outdoor unit, also called the condensing unit and an indoor unit, also called the air handler. The function of a central cooling air unit is to transport heat from one station to another. The vehicle your system uses to carry the heat is called a refrigerant, commonly referred to as Freon.
The compressor in your outdoor unit changes the refrigerant or Freon into a high temperature, high pressure gas. As that gas flows through the outdoor coil, it loses heat and condenses into a high temperature, high pressure liquid. This liquid refrigerant goes through copper tubing into the evaporator coil. There the refrigerant expands. Its sudden expansion turns the refrigerant into a low temperature and low pressure gas. This gas then soaks up heat from the air circulating in the duct work. The cooled down air is then distributed back through your house. The meantime, the heat that was absorbed by the refrigerant is transported back outside through copper tubing and released into the outside air. Dirty coils and improper refrigerant levels can cause your system to cool less efficiently than it should. An inefficient cooling system means higher energy bills. It also forces your compressor to work harder than is necessary and can actually shorten the life span of your cooling unit. Having an annual cooling system tune-up by a licensed technician would include an inspection of the coils and the checking of your refrigerant charge, to insure that your cooling system is running efficiently.
How The Central Cooling System Dehumidifies the Air
When the warm air circulating through your ducts passes over the evaporator coil, it is immediately cooled and can no longer hold as much moisture as it did at a higher temperature. The excess moisture condenses on the outside of the coils and is carried away through a drain. The process is similar to what happens when moisture condenses on the outside of a glass of ice water on a hot, humid day.
Sometimes, the drain lines may become clogged and your system will not drain the way it should. This can result in a drain pan overflow, which leads to water leaks in your ceiling, walls and or floors.
Efficiency Ratings
SEER RATING: Your cooling system efficiency is rated in SEER (Seasonal Energy Efficiency Ratio). This measurement of a cooling unit or heat pump system energy efficiency takes into account the cooling efficiency of the system under various weather conditions. SEER is determined by dividing the total cooling provided during warm months (in BTU'S) by the total energy (watt-hours) consumed during the same period. We recommend a minimum SEER of 14.

BENEFITS: A high-efficiency system means lower electric bills per month. While a high efficiency cooling and heating system may cost a little more up front compared to a less efficient system, you'll recover the price difference in a very short time. High-efficiency systems also save our energy resources. You'll have the satisfaction of helping to protect our environment. That's a savings that benefit us all.
The Importance of a Matched System
Your cooling system consists of an outdoor unit (the condensing unit) and an indoor unit (evaporator). These two components are designed to work together as a coordinated team to provide top performance, maximum efficiency, and comfort. Whenever you install a new outdoor unit, you should install a new, equally efficient "matched" indoor unit at the same time. While replacing the outdoor unit only may initially offer you the lowest price, it may prove more expensive over time. When your cooling system components don't match, your system may still work, but it won't perform at the promised energy efficiency. So, the fact is, your system could be up to 15% less efficient than stated. You may be sacrificing comfort, as well, as a mismatched system and may have difficulty keeping up on the hottest days of the year!
The Importance of a Yearly HVAC Inspection
Would you drive a car year after year without ever changing the oil or taking it to a mechanic for a tune-up? Probably not. Like your car, your cooling and heating systems must be maintained in order to run efficiently and dependably. An annual cooling check-up allows a technician to identify minor problems before they become major ones.
Tri County Air Conditioning & Heating performs yearly cooling system inspections on residential structures.
