Three Concerns with Vehicle Service During COVID-19

Posted by Cheolwon Byeon on

Three Concerns with Vehicle Service During COVID-19   Looking closely at vehicle service, there are three areas we’re most concerned with: Technical safety Vehicle Cleanliness Inside the HVAC Case First, the technician needs to safely approach the vehicle and perform some type of sanitizing (which includes the door handles, steering wheel, shifter handle, seat belt buckles, ignition keys, and ignition switch) prior to bringing the vehicle into the shop for service. This protects the technician from surface contamination that may be present on the vehicle and should be performed while wearing PPE (personal protective equipment) like gloves, goggles or a...

Availability of A/C Detail Parts

Posted by Cheolwon Byeon on

Detail parts and why they are difficult to obtain   Detail parts are small inexpensive parts that fit into a larger assembly. For example, the high pressure switch on the back of the compressor is a detail part. In recent years, fixing A/C issues has become more expensive because it is easier and more profitable for distributors to only sell larger parts like compressors and condensers rather than cheaper detail parts. Since detail parts are not as readily available as they have been in the past, fixing common A/C issues has become more expensive and inconvenient. For example, condenser orifice...

The Importance of a Clean Condenser

Posted by Cheolwon Byeon on

About the condenser Condensers are a critical part of an AC system. Unfortunately, they are easily damaged due to the thin metal fins in their design. Every AC system includes a condenser, which takes in warm refrigerant vapor discharged from the compressor and outputs hot refrigerant liquid. The refrigerant vapor and liquid flows through a series of small tubes that run in rows through the condensor. The image below is a cross section of a condensor and shows the tubes.     The state change from vapor to liquid releases a lot of heat, which is dissipated by air flowing...

Understanding Your A/C System

Posted by Cheolwon Byeon on

Compressor The compressor is the main component of the system. It pressurizes the refrigerant so it can flow through the system. Since it is one of the few moving parts in the A/C system, it needs a constant flow of refrigerant and clean lubricant to prevent it from failing. A loss of refrigerant decreases lubricant flow back to the compressor and is likely to cause it to overheat and fail. When a compressor fails, it will cause small metal shavings and debris to be pumped into the system.   Condenser The pressurized refrigerant, as vapor flows from the compressor to...
