Chiller maintenance (also called chiller servicing or PPM — Planned Preventive Maintenance) involves routine inspection, cleaning, calibration and testing of your chiller to maintain performance, efficiency and reliability. A typical service includes cleaning condenser and evaporator tubes or coils, checking refrigerant charge and pressures, oil analysis, inspecting electrical connections, calibrating sensors, and testing safety controls. Regular maintenance prevents costly breakdowns, maintains efficiency, and ensures F-gas compliance. HVACX is a marketplace — we connect you with independent chiller engineers who carry out the maintenance. We do not perform chiller servicing ourselves.

Chiller maintenance costs vary by chiller type, capacity and service scope. A single service visit for a commercial scroll chiller typically costs £200–£600. Screw and centrifugal chillers range from £500–£1,500 per visit. Annual PPM contracts covering multiple visits, oil analysis, and F-gas leak checks are priced per chiller per year. Post your request on HVACX to receive competing quotes from multiple chiller engineers.
Commercial chillers should be serviced at least annually, with many requiring two or more visits per year depending on usage and criticality. F-gas regulations require annual leak checks for systems above certain refrigerant charge thresholds. High-criticality process chillers may benefit from quarterly maintenance.
