Equipment AC Service and Repair

At Thompson Machinery, we understand that a hot cab can impact safety, focus and overall productivity. Through our heavy equipment AC repair and service, we help keep your operators cool, comfortable and focused. Our technicians are factory-trained and understand how AC systems work. This expertise helps us diagnose issues and ensure your machine gets the correct service to resume operations. Since 1944, we have used our expertise to meet clients’ needs and build lasting partnerships.

Comprehensive Equipment AC Service

We service AC systems for a wide range of equipment in construction, mining and other industries. Here’s a look at our thorough process.

Visual Inspection

A careful visual check helps us catch potential issues early. We inspect:

  • AC and heater hoses: We examine these hoses for cracks, wear or visible leaks. This proactive step can prevent refrigerant loss and protect the structural integrity of components.
  • The moisture indicator: Our experts check the moisture indicator to gauge the level of humidity within the AC system. Removing moisture can prevent corrosion and system blockages.
  • Drain hoses: A clear drain hose removes condensation from the evaporator. We verify that it is free of blockages to help prevent water from backing up into the cab.

Operational Checks

We assess:

  • Fan motor and temperature control: We test fan speeds and temperature settings to confirm the controls are responding correctly and providing consistent airflow.
  • Cooling and heating performance: Measuring the air temperature at the evaporator, we verify that the AC and heating systems are achieving the correct temperature outputs.
  • System noise evaluation: Unusual noises can point to a variety of issues. We listen carefully to identify any sounds that might indicate a deeper problem.

Air Clean Compartment Inspection

Cleanliness affects air quality and system efficiency. To confirm correct performance, our technicians check:

  • Evaporator and condenser coils: We inspect the evaporator and condenser coils for dirt and debris. Clean coils promote efficient heat exchange and optimal cooling.
  • Cab filter inspection and cleaning: A clean cab filter improves air quality for the operator and ensures strong airflow. We check and clean or replace the filters as needed.

Pressure Test System

Our technicians perform a detailed analysis of your pressure system’s performance through:

  • High and low-pressure readings: We test the high and low-pressure sides of the system at both low and high idle.
  • Ambient and evaporator temperature readings: Our experts compare the pressure readings to the ambient air temperature and the evaporator air temperature.

These combined readings let us accurately diagnose issues with refrigerant levels, airflow and compressor function, so we can pinpoint the cause of any cooling problems.

Engine Compartment Inspection

Because the AC system integrates directly with the engine, a complete check of this area is crucial. Our inspection includes:

  • Belt condition and tension: We check the drive belts for wear, cracks and proper tension to confirm correct compressor operation.
  • Compressor and clutch: Our team visually inspects the AC compressor for leaks or wear. We also check to see if the electrical clutch connection is secure.
  • Mounting hardware: We verify that all compressor mounting brackets are secure to prevent vibration that could lead to damage.

Expert Heavy Equipment AC Repair

Once our inspection is complete and we’ve diagnosed the issue, our team completes the necessary AC repairs on equipment from Cat® and other brands. Whether your investment requires a refrigerant recharge, a new hose assembly or a complete compressor replacement, our team follows manufacturer specifications and uses high-quality parts to get your cabin climate system back in service. With 24/7 parts support, we can complete repairs faster to minimize downtime. We maintain a fleet of over 50 field service vehicles and more than 200 trained experts to repair and service the air conditioning systems of your equipment.
