Air Conditioning Issues Phoenix

Phoenix heat plays an important role in the issues your air conditioning may be having. This starts as the compressor has a breakdown in the refrigerant. When the refrigerant fluids break down it causes a lack of lubrication properly to the compressor, which much like lack of oil in a motor, will cause wear and cause particle buildup. These metal particles travel through the A/C systems from the compressor and cause the system to lack performance; loss of airflow.

Car Air Conditioning Repair: Troubleshooting


Why does my A/C have weak airflow?

There’s nothing worse than braving a hot Summer day in Phoenix, only to find your auto ac is not cooling properly or providing proper airflow. This is a great precautionary clue that tells you to get your air conditioning serviced before more damage to the over a/c system spreads.

There are several main causes to this lack of air flow, here are the main concerns:

  • Mold or mildew may have accumulated in the evaporator core from residual moisture that occurs during the cooling process. When this happens, air will have trouble reaching your air vents.
  • The blower hose that supplies air to the AC unit has come loose.
  • Air ventilation fan is now flowing very well, causing lack of air flow.
  • One or more seals have been compromised. A lack of proper seals can result in the entire system failing to function properly.

Auto Air Conditioning Not Blowing Cold

This has got to be more frustrating than the AC not working properly. It seems to be blowing proper airflow but the temperature is not cooling down. The sooner your air conditioning diagnostic is completed, the faster you can repair the problems without creating further AC maintenance and service repairs.

Causes of Air Conditioning Not Cooling Down:

  • Damaged or failed condenser or evaporator
  • A clogged expansion tube or refrigerant charging hose
  • Failed compressor or compressor clutch
  • Failed blower motor or blower motor resistor
  • Vacuum leaks
  • A Freon leak caused by a failed o-ring, seal, hose or component
  • Failed switch, fuse, relay, control module, blend door or solenoid

A leak in the air condition system is a common occurrence that results in a lack of blowing cold air. When the AC system opens up, or develops a leak, it can lead to expensive auto repairs unless it can be discovered early. It becomes a more expensive repair when moisture gathers within the A/C system and damages other parts.

Testing for an A/C System Leak

Your mobile mechanic can use several tools to test your air conditioning system for leaks, cracks or damages. The most common tools used to test a leak is to use a dye. The refrigerants are mixed with U.V. dye that can be visible when using a black light. This is helpful in finding the source of the leak. Another common tool is a special tool that detects the refrigerant chemicals to determine if there is in fact a leak.

What Causes An A/C System to Crack or Leak?

The worst problem your ac system could face is to gather moisture or for the seals and hoses to age over time. Once the seals and hoses lose their elastic properties, it’s easy for the Freon to escape into other areas within the system or to leak entirely, causing moisture in unwanted areas. Once moisture gathers within the a/c system it corrects a corrosive acid that is impossible to repair, but will need complete replacement.
