Fujitsu‑trained engineering for modern HVACR

Today’s commercial spaces often integrate refrigeration with HVAC and building controls. Our factory training at Fujitsu and experience with Mitsubishi Electric, Midea, Gree, and Haier help us troubleshoot sensors, boards, communication errors, and staging issues that standard “swap and hope” repairs miss. That means fewer callbacks, tighter temperature control, and better energy performance.

Our repair process

• Assessment: We listen to symptoms and document system history.
• Diagnostics: Targeted testing of refrigerant circuit, airflow, controls, and electrical.
• Findings: Clear explanation with photos, prioritized options, and upfront pricing.
• Repair: Code‑compliant workmanship, clean brazing, proper evacuation and weighing, verified superheat/subcooling, and control calibration.
• Validation: Temperature pull‑down and performance checks before we leave.

We stock common parts and use quality components to prevent repeat failures. You get a documented fix and maintenance guidance to keep your equipment steady.
