Indoor air conditioner units are often part of a switch-unit with a built-in furnace. In ideal operation conditions, an air conditioner unit produces a constant flow of cool air to the home. The air is cooled via a refrigerant agent known as coolant, which is pumped through the unit through a system of tubes and pipes. When the unit is functioning properly, there is no build up or accumulation, but there are issues which can crop up that lead to the unit building up ice and freezing as opposed to cooling the home. Filters Air conditioners and furnaces rely on airflow to push the air through the vents that cool and heat a home. In both cases, the filters on the outside of the unit are there to ensure proper airflow and restrict debris from entering the unit. If these filters ever become blocked, the restricted airflow leads to ice building up inside of the air conditioner because it isn’t being cycled out into the vents fast enough. The longer this goes on, the more ice that builds up, until the point the unit completely freezes.

For best results, always clean the air filters every few months. Evaporator Coils Evaporator coils in an air conditioner are there to help with heat exchange, absorbing heat that needs to be cooled down. The evaporator coils are filled with the coolant from the air conditioner, and cool the air that passes through. Over time, these coils collect dust and debris just like the air filters. As this debris builds up, the effectiveness of the unit is compromised. Over time as more dirt accumulates, the coils no longer function properly, and rather than cooling off the air, they begin to build up frost and freeze. Clean the coils every few months for best results. Refrigerant Issues When everything within an air conditioner is working perfectly, the coolant in the reservoir lasts a lifetime and beyond, as they are built to last, not to leak, and the coolant is continually recycled without ever being used up. However, leaks can occur, either through faulty installation or through breakdown of other components within the interior over time.

When low levels of coolant occur, ice buildup and freezing can occur as the unit tries to work overtime to produce cooler air. Leaking coolant is also another cause of ice buildup and eventual freezing of the unit. Having a licensed technician inspect the unit and repair the leak/refill the coolant reservoir is the only option. Outside Temperature Air conditioners work best in temperatures above 60 degrees. If the exterior temperatures are too low, the coils within the unit are colder than they would be in summer/hot weather, which leads to the air conditioner coils refrigerating the room air, rather than just the air within the unit itself. This leads to ice buildup and freezing. The problem tends to be more prevalent at night than during the daytime hours and is easily solved by simply switching the unit to “Fan” mode to let it circulate the cold air until the ice melts away. Why is my indoor central air conditioner leaking water? An indoor central air conditioning unit may be leaking water due to a buildup of excess condensation on the internal cold evaporator coil, a blocked condensate drainage pipe, a rusted condensate drain pan, a frozen evaporator coil or improper installation.

If water is noticed beneath an air conditioning unit, it is important to unplug the unit first before attempting to diagnose the problem. How do you remove bad smells from a central air system? Most air conditioning units have a dehumidifier built into the design. This dehumidifier works to pull water out of the air by passing it over a chilled evaporator coil in the body of the unit. home ac unit efficiencyOn a particularly humid day, the dehumidifier pulls more moisture out of the air than normal. cost of external ac unitThe water builds up on the evaporator coil in excessive amounts and could overflow the drainage pipe or leak through the unit's drain pan. cleaning your ac unitIf the drainage pipe becomes obstructed by dirt, leaves or insects, the water formed on the evaporation coil can overflow and leak out of the unit.

Ice can also build up on the evaporator coil if the air conditioning unit is not properly ventilated due to a dirty air filter. Once the air filter is changed, the ice melts from the coil and could leak out of the unit. Finally, if the air conditioning unit was installed on a slant, this could cause the water to run off of the drain pan and leak out of the unit. Where is the drain pipe in a central air conditioner?

Unlike window air conditioning units that must be installed in a window frame, portable air conditioners are placed on the floor and can be easily moved from room to room. Portable air conditioners are a good choice for temporary building use, in buildings that do not have a window opening, or in buildings where the air conditioner will need to be moved from room to room. How Does a Portable Air Conditioner Work?

Portable air conditioners have a clever design that allows them to be used without installation. Air conditioners need to intake fresh air and expel hot air outdoors. Air conditioners expel the hot air outdoors to prevent the hot air from entering back into the building. Window air conditioning units must be installed in a window so that the back of the unit is outdoors. The outdoor part of the unit brings in fresh air and pushes out hot air. Central air conditioning units operate in a similar manner as window units. They are installed outdoors to allow cool air intake and hot air out take. Portable air conditioners avoid the issue of installation to allow for air exposure, by using a tube. One end of the tube connects to the unit and the other end is placed through a window, a mail slot, or other opening. When the unit is moved, the tube is moved with it. The portable air conditioner and the tube are both light in weight. Operating a Portable Air Conditioner To operation of a portable air conditioner is not complicated.

The unit is plugged in, one hose is connected to the unit and the other end is led to the outdoors, and the unit is turned on. The only special care required is an emptying of the reservoir. All air conditioners get a condensation build-up. This is usually not an issue because window and central air conditioners are installed either partly or fully outdoors. Window and central air conditioning units allow the condensation to drip out of the unit. Since a portable air conditioner is kept indoors, the unit holds the condensation in a reservoir. The reservoir must be emptied on a regular basis. Most models automatically shut off if the reservoir becomes full to prevent leakage. The energy consumption of a portable air conditioner depends on the model. Portable air conditioners come in various sizes. Different sizes are suitable for different spaces. Some only will only one room, others can cool a whole building. The portable air conditioner specifications on the package lists how many square feet the unit cools.

The use of a portable air conditioner over a central unit can save energy. A small energy efficient portable unit can be used in a room with a closed door. The closed door keeps the cool air in the room. A central unit uses enough energy to cool the whole building. When only one room needs to be cooled, a small portable unit is the smart energy saving choice. Portable air conditioners save you money while still keeping a commonly used room in your home cool.
