"A Summer Must: Air Conditioner Repairs"

Air Conditioner

• The air conditioner is similar to a refrigerator, in the sense that, they use energy to pull heat out of cool interior space.

• An air conditioner is responsible for cooling a larger area, which means that knowing how the unit works and what repairs are needed is crucial to staying comfortable all summer long.

How Air Conditioners Work• Air conditioners consist of three important parts: the

compressor pump, condenser, and evaporator coils. • These parts pass refrigerant through each other that

extracts heat from the air around it and turns it into a gas.

• The refrigerant gas is then pumped to the compressor and is heated into a liquid again to start the process over.

• Cool air is then blown back into the building by vents until the desired temperature is reached.

Common Air Conditioner Repairs• There are many components to an air conditioner

and, therefore, there are many reasons it may fail or require fixing.

• Common air conditioner repairs are due to:1. Low refrigerant2. Frozen evaporator coil3. Faulty wiring4. Outside fan malfunction5. Dirty filters or coils6. Drainage problems

Low Refrigerant

Usually indicates a refrigerant leak and can lead to many problems.

Frozen Evaporator Coil

Could be caused by air restrictions from the air filters or ductwork and can also be caused by low refrigerant.

Outside Fan Malfunction

Can be due to many things such as defective equipment or the presence of a foreign object. May lead to a plethora of problems including an overheated compressor.

Dirty Filters or Coils

A natural occurrence that develops over time which then causes your air conditioner to run inefficiently or even the compressor or fans to break down.

Filters

• Usually get dirty or clogged and can reduce efficiency of you’re A/C.

• It is ideal to replace air conditioning filters every month or two during the summer and possibly more depending on pets.

Condenser and Evaporator Coils

• Over time the condenser and evaporator coils will collect dirt.

• This will reduce heat transfer efficiency and as a result your air conditioning filter.

Coils’ Fins

• Condenser and evaporator coils have aluminum fins on them that help distribute the hot and cool air more effectively.

• Bent fins can disrupt the flow of air.

• A “fin comb” can fins to almost original shape.

Condensate Drains

• A clogged drain can reduce the ability of you’re A/C lowering humidity.

• This can lead to discolored walls due to moisture.

• Passing a stiff wire through the drain channels should unclog it.
