How Air Conditioning Works
The more common central cooling system is a split system, which includes an outdoor unit with a condenser coil and compressor, and an indoor evaporator coil with a furnace or air handler. The compressor pumps a chemical called refrigerant through the system. The air inside your home blows across the evaporator coil and the heat energy from the air transfers to the refrigerant inside the coil. The refrigerant is like a sponge, absorbing the heat from the air. The air is now “cool”. The cooler air is circulated back through the home providing comfort. The refrigerant is pumped back to the compressor where the heat absorbed by the refrigerant is released and cycle begins again. Humidity is also condensed out of the air. Your cooling system is usually combined with your central heating system because they share the same duct work for distributing conditioned air through your home.
Heat pumps are a great solution for your comfort system. It works
to provide both heating and cooling. Year-round, energy-efficient
indoor comfort for moderate climates. A central heat pump helps
maintain comfortable temperatures inside your home and reduces
humidity levels year-round while saving on your energy bill.
New air conditioners provide more comfort and efficiency than ever. You can enjoy complete comfort on the hottest days of the year and lower your cooling costs at the same time. When the air conditioner is properly matched with a furnace or air handler, you get maximum efficiency and longer system life. Air conditioning and cooling efficiency is measured using a Seasonal Energy Efficiency Ratio (SEER). A higher SEER rating means higher energy efficiency. Increased efficiency may substantially lower your home cooling costs. Quiet comfort Variable speed blower motor equipment allows for extremely quiet operation.
An air handler is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements. Air handlers usually connect to duct work that distributes the conditioned air through the building, and returns it back to the air handler. Sometimes the air handler gets air directly to and from the space served, without duct work.
A furnace works to keep a home warm in the winter and plays a critical part in the operation of an air conditioner. Furnaces produce heat through a heat exchanger or heat strips. Air from your return air ducts is blown over the heat exchanger or heat strips which warms the air. The furnace's blower then blows the warmed air into the duct work. During summer months, the blower circulates return air over the indoor coil portion of the home's air conditioner. The evaporator coil is typically installed on top of the furnace.
Geothermal heat pumps use the earth as a heat source in the winter and as a heat storage source in the summer. The ground loop components of a geothermal heating and cooling system can last up to 50 years!
Ground and water temperatures, 6 feet below the earth's surface, stay relatively constant throughout the year. This allows the system to provide extremely efficient heating or cooling all year long in virtually any climate. Sometimes the term "environmental comfort system" is used to describe a geothermal heat pump. This happens because a heat pump absorbs or rejects heat from the earth and has absolutely no impact on the environment.
Installing the correct evaporator coil is essential for getting the best performance and comfort from your central air conditioning or heat pump system. As air is passed through the coil, the freon will absorb the heat and you in return get that cold breeze throughout the house. For best performance, it is recommended that you install a brand-name coil with a brand-name air conditioner or heat pump system. And as always, brand-name equipment offers some of the best warranty protection coverage in the heating and cooling industry.
The mini split system provides high-efficiency quiet comfort in any room of your house. While our single-zone system allows you to heat or cool one space at a time, our multi-zone system allows you to heat or cool up to five rooms with just one outdoor condensing section. Indoor air handlers can be automatically programmed with a 24-hour timer function, or controlled with the included remote control for maximum individualized comfort. As an added benefit, mini splits give you the option of only heating or cooling rooms you use the most instead of the standard centralized “one-size-fits-all” approach thereby providing extra energy savings.
