Cooling Home or Business

coolingAir Conditioning was voted to be the #1 new technology invented during the last century.

The Cooling System in your home is made up of 3 major components, The Furnace, The Evaporator; which is attached to the furnace, and The Condenser.  These components can be put together as one unit, called the “Packaged Unit”, which can be found on rooftops, and on the ground outside of many homes and businesses, or they can be assembled on site, which is called a “Split System”.

The Split System is more predominantly popular around the United States and is getting more so each day.  One of the benefits of a split system is that the components are available at higher efficiency ratings and they can be used in more applications.

Like Heating, Cooling is also controlled by the thermostat.  When you set the thermostat to cool your home, two things happen; both the furnace blower motor and the condensing unit outside turn on.

The Furnace

The furnace blower motor turns on and moves the air from your house, through the return air duct, usually the big grille located in a hallway wall or ceiling, through the evaporator, and back in to the supply duct system which distributes the air throughout your home or office.

The Evaporator

Contrary to popular opinion, the air conditioner does not add cold air to your home.
As the air in your home circulates through the evaporator, heat is removed from that air each time it passes through, leaving you with cold air.  It is extremely important to keep the evaporator coil clean and free of debris.  The air filter inside your home does a fairly good job of keeping the evaporator coil clean, but all too often, homeowners tend to forget to change the filter, which causes the system to work harder and perform less efficiently.  When a filter becomes plugged with debris, the dirty air will find the next path of least resistance, travel around the filter, and cling to the evaporator coil.  A yearly tune up of the cooling system should include an inspection of the evaporator coil to make sure it is clean and free of debris.  This inspection is included in all of the cooling system tune-ups performed by ARS Comfort Solutions, Inc.

The Condenser

The condenser is the “Heart” of your air conditioner.  It contains the Compressor, the Condenser Fan Motor, and the Condenser Coil.

After the evaporator removes heat from the air passing through it, the heat travels in refrigerant to the condenser via the suction line, the large copper refrigerant line which goes between the evaporator and the condenser.  As the refrigerant enters the condenser, it is compressed to a more liquid state in the compressor, and then passes through the condenser coil.
While traveling through the Condenser Coil, the heat in the refrigerant, which was removed from your homes indoor air, is then removed from the refrigerant with the assistance of the condenser fan in much the same way as the heat was absorbed by the evaporator with the assistance of the furnace blower motor.  As the condenser fan sucks air through the condenser coil, the heat is removed from the refrigerant, and expelled to the outside air.  This is why the air coming out of the condenser is much hotter than the outside air temperature, it is the outside air temperature plus the addition of the heat removed from the air inside your home.

The refrigerant then leaves the condenser coil via the liquid line, the small copper refrigerant line which runs between the evaporator and condenser, travels back through the evaporator, and starts the whole process of absorbing heat from the inside air and expelling heat to the outside air all over again.

The condenser coil is another coil which needs to be kept clean and free of debris.  It is the one coil that has absolutely no protection from the dirt, dust, and debris floating around in the atmosphere.  As the dirt and debris cling to the fins of the coil, they also insulate the coil.  Just like the insulation of the walls in your home which keeps the heat out and cold air in on a hot day, the dirt and debris that build up on a condenser coil though normal operation will insulate the coil and keep the heat in the refrigerant, preventing it from escaping into the outside air.
This is a serious decrease in performance and efficiency of your cooling system, causing your air conditioner to work harder, run longer, and cost more to operate.

Cooling System Service

As stated above, if you would like to keep the cooling system operating at peak efficiency, it is extremely important to keep the evaporator and condenser coil of the cooling system clean and free of debris.  The air filter inside your home should be changed a minimum of 3 times per year, or if you have a cleanable filter, the filter should be cleaned once per month.  A good way to remember to clean your filter is to do it every time you receive a utility bill.  But all too often, homeowners tend to forget to change or clean the filter, which causes the system to work harder and perform less efficiently.  Performing a yearly tune up on the cooling system which is recommended by all manufacturers for ongoing performance and longevity is also required to maintain the manufacturer’s warranties.  Call ARS Comfort Solutions, Inc today to schedule your tune up and see how you can join our Improved Performance Program

Refrigerant pressures are another key ingredient to proper system service.
There are only two ways to properly check a refrigerant system charge.  The Superheat Method and The SubCooling method.  All too often technicians simply put their gauges on the system, look at the pressures, and decide if the system is under-charged, over-charged, or just right.

If you are having a cooling system tune-up and the service technician is not using thermometers, measuring wet-bulb temperatures, and referring to charging charts, then you are using an un-qualified technician and need to get a new Service Company.
