The real problem
Weak cooling or heating may come from refrigerant, thermal circulation, airflow or controls. Reliable comfort starts by understanding why the system stopped responding.
Who we serve
Built for the field.
Effective in every season.
Working equipment comes first. Cooling, heating, defrosting or airflow: when the work fits our capabilities, we find the cause.
Heavy equipment
Excavators, loaders and equipment that is difficult to move.
↗Fleets & contractors
Documented findings that support repair planning.
↗Other vehicles
Pickups, commercial vehicles and thermal-comfort systems when the job fits.
↗The LOGIC method
An evidence-driven intervention.
Measurements from your machine outrank assumptions.
Measure
Pressures, temperatures, electrical supply, airflow and actual behaviour.
Isolate
Leak testing, nitrogen pressure testing, electronic detection and component validation.
Repair
Correct the cause before restoring specified refrigerant and oil quantities.
Confirm
Documented performance test under recorded ambient conditions.
Comfort and visibility year-round
HVAC is more than refrigerant.
Weak heating, poor windshield defrosting or low airflow may come from thermal circulation, an air door, actuator, blower or restriction. We verify the mechanism before replacing components.
Winter heating
Engine temperature, coolant circulation, heater-core performance and actual outlet temperature.
Actuators and air doors
Blend, mode and recirculation actuators, stuck doors and electrical or electronic controls.
Restricted airflow
Filters, blocked evaporator or heater core, blower, speed module, ducts and air inlets.
Uneven temperature
Hot on one side and cold on the other, poor defrosting, wrong outlet selection or unstable temperature.
