Reasons Your Air Conditioner is Not Cooling

Air conditioners have become an essential part of our lives. We depend on them to keep our homes and offices cool, especially during the summer when the heat is at its peak.

A commercial air conditioner system contains several units that work together. A glitch in any of these components makes the appliance function poorly.

Reasons Your Air Conditioner is Not Cooling

Why Your AC is Not Cooling

Low Refrigerant

Refrigerant is an essential element of your air conditioner. The refrigerant allows your air conditioner to separate heat and humidity from the environment.

When the refrigerant is low, it might be because of a leak in the evaporator coil. The ability of your air conditioner to produce cool air will be negatively impacted.

Clogged Condenser Coil

The condenser coil is a series of thin metals, the output unit of the air conditioning system. Its function is to extract heat from the inside to the outside. When the condenser coil is covered with dirt and dust, it becomes ineffective at removing heated air.

This can cause the condenser to overwork to eliminate heat from the building. This can lead to wear and tear of parts and system failure if not quickly addressed.

Frozen Evaporator Coil

The evaporator houses the refrigerant. It absorbs heat to maintain a warm temperature. When the warm air circulation is interrupted, the coil becomes frozen. This makes your AC deliver warm air.

Faulty Fans

There are two fans in your air conditioning system. Both are responsible for air circulation. One works with the evaporator coil to distribute cool air within the room. The other is paired with the condenser coil.

Failure of either of the fans will affect the room temperature. Common causes of fan problems are broken parts and poor lubrication. Fan problems may cause the compressor to fail, which in most cases is the death of the air conditioning system.

Clogged Drain

A draining system is incorporated into the air conditioner to remove all moisture trapped in the air. When the drain line is clogged, the water flows back into the system.

Undersized Air Conditioner

A small air conditioner in an ample building space won’t make any difference in the room temperature, especially during the summer heat. Air conditioners have a capacity that varies by the rate of cooling they can produce in an hour.

Leaking Ducts

Ducts are distributed throughout your air conditioning system, carrying various things from refrigerants to cool air and water. The operation of an air conditioner is compromised when there is a leak in any of the ducts.

Other Causes Include

  • Dirty Air Filter
  • Thermostat problems
  • Compressor Failure
  • Antiquated air conditioner

Tips on Air Conditioner Maintenance

  • Replace dirty filter
  • Keep the outdoor unit as clean and transparent as possible
  • Regular maintenance by HVAC
  • Fix broken parts and leaky ducts as soon as they are discovered.
  • Consult HVAC professionals on the size of the air conditioner that is best suited for your space.

More than half of air conditioners’ problems are due to poor maintenance. We recommend that you carry out preventive care at least twice a year.  Experts should carry out this exercise.
