Identifying the Severity of an Air Conditioning Problem in an HVAC Emergency

Identifying the Severity of an Air Conditioning Problem in an HVAC Emergency

Air conditioning units are designed to cool air down to a specific temperature. If they can’t do that, then they won’t work properly. This usually happens if the unit runs too long without AC maintenance Phoenix. If your air conditioning system runs longer than required, it can cause damage to the compressor. This could result in the need for the best AC repair in Phoenix.

You may encounter the following air conditioning problems in case of an HVAC emergency.

  • Dehumidifier Problems

Dehumidifiers use fans to extract warm, moist air from the house, cool it down, and then run it through a filter to remove moisture from the air. The air passes through a refrigerant, which causes the air inside the dehumidifier to become cooler than the outside temperature.

Overloaded dehumidifiers can cause damage to their internal components. In addition, they can create condensation on the walls and ceiling of your home. Condensation can often lead to mold and mildew.

  • Dust and Debris

The problem with air conditioning systems is that they can get clogged with dust and debris. If the filters aren’t cleaned regularly, they can eventually stop working altogether.

  • Condensation Issues

When humidity levels are increased, the air conditioner has difficulty removing moisture from the air. This can drive condensation inside the unit and damage the compressor. If this occurs, the compressor may need to be replaced.

  • Overheating

Poor airflow can cause the air conditioners to overheat. The system can get too hot if the fan does not circulate enough air through the coils. In extreme cases, the system could shut down due to overheating, which requires the best AC repair Phoenix.

  • Low Refrigerant

Low refrigerant levels can drive the air conditioner to freeze up. Refrigerants are used to keep the air conditioner cool. The air conditioner cannot operate efficiently when the refrigerant level drops low.

  • Sensor Issues

If your thermostat has been malfunctioning for some time, the sensors can be faulty. This would mean that the thermostat doesn’t recognize the change in temperature. This can happen if the wires are shorted out, or the device has been damaged.

  • Frozen Coil

A frozen coil happens when the compressor stops running due to a power outage. When the compressor stops, the refrigerant gas expands and causes the coil to freeze.

  • Fan Motor

The fan motor is what runs your AC unit. They are usually driven by either an electric motor or a small internal combustion engine. The entire system will not function correctly if the fan motor fails.

  • Disruption of the Evaporator

Disruption of the evaporator in air conditioners can happen if the airflow through the evaporator becomes blocked. As a result, heat transfer from the refrigerant gas to the air is reduced, causing the compressor to work harder and eventually shut down.

  • Expansion Valve Failure

The expansion valve failure in air conditioners can prevent the refrigerant gas from expanding properly. If the expansion valve is damaged, the refrigerant gas will expand too much, causing the compressor to run continuously and possibly burn out.


An air conditioning system consists of many components, including the compressor, condenser coil, evaporator coil, expansion valve, and blower. When these components fail, you should contact the professionals at KJ’s Cooling & Heating LLC, as it is a one-stop shop for AC maintenance in Phoenix.
