How Does an Air Conditioner Work?

The warm air from your room is removed by a fan and blown over evaporator coils. The liquid coolant in the coils absorbs the heat and the now colder air is blown back into the room. The hotter coolant changes into a gas and is pumped outside your home by the compressor and into the condenser and cooling fins.

The excess heat is now radiated to the outside air. Having lost the heat energy, the gas changes back into a liquid coolant and is pumped back to the evaporator coil and the cycle continues. The air conditioner relies on several components that need to all work properly to get the maximum efficiency out of the unit.

When Do You Need an AC Repair?

Most of us take the reliability of an air conditioner for granted, but unless they are looked after with regular service, they will eventually break down. At best they will work at reduced efficiency, and you will experience some of the following signs.

• Increased energy bills.
• Less cool air is produced.
• Airflow from the unit is weakened.
• You notice strange noises and smells coming from the unit.
• Increased humidity levels.
• Puddles of water forming around the unit.
• Ignoring these signs will only lead to an AC repair.

What is the cause of these problems?

Low Coolant Levels

If the air conditioner does not have enough coolant due to a leak, then the cooling effect is reduced as not enough heat is absorbed from the warm air blown over the evaporator coils.

To make up for this the other components in the unit will work harder to maintain the chosen temperature. As the components are working harder, they will use more energy and increase your utility bills.

Harder working units will get hotter and are more likely to burn out and need an AC repair. A service from One Hour Air Conditioning & Heating of Dallas will ensure that the coolant levels are topped up.

Evaporator Coil Starts to Freeze

When frost and ice start to form on the evaporator coil it could be due to several reasons. Low coolant levels will cause this as well as restricting airflow over the evaporator coil. The coil needs a constant supply of warm air to be blown over it, or it starts to freeze.

A dirty air filter will restrict airflow, and this will need to be cleaned or changed regularly. Any dirt that accumulates on the coil will reduce the heat transfer between the coil and warm air, so the coil will need to be cleaned as well.

Dirty Condensers and Cooling Fins

The condenser and cooling also need a constant supply of air blown over them to radiate the excess heat to the outside air. Anything that blocks this flow such as moss and weeds growing on the condenser will need to be removed, as well as any dirt or grime.

This layer of dirt and grime acts as an insulating layer reducing heat transfer, and so the condenser and cooling fins will need to be regularly cleaned.

Problems With Fans

A faulty fan will reduce the airflow over the evaporator coil, condenser, and cooling fins, resulting in reduced cool air from the air conditioner. This may be the source of any strange noises you hear coming from your unit. A screeching sound could be the result of a worn-out fan belt, and clunking sounds suggest a loose or bent blade hitting the inside of your unit

Clogged AC Drain Line

Any moisture from the humid air will end up in a drip pan in your air conditioner, and then out via an AC drain line. The humid conditions can cause mold and mildew to grow inside the line and cause a blockage.

This could cause the air conditioner to shut down, so it is worth checking whether the AC drain line is blocked before calling for an AC repair. The blocked line increases humidity levels in your home and because the excess moisture has no place to escape to, will overflow the drip pan into your home.

Leaking Ducts

It has been estimated that up to 30% of the air conditioner’s energy will be lost as cool air escapes through damaged ducts or joints. So, it is always worth inspecting any air ducts that you have.

Many of these issues will be resolved during service from one of our many highly trained technicians throughout Dallas.
