Heat Pump Service
in St Albans.

Useful facts,
not assumptions.

Postcode and system-detail triage before any appointment is arranged. Routine inspection of the heat pump, hydraulic circuit, emitters, controls, sensors, electrical isolators and condensate or drainage arrangements, subject to the equipment type and manufacturer requirements. Performance and controls review, including whether schedules, weather compensation, flow temperatures and user settings are appropriate for the building. Maintenance planning that considers retrofit sequencing, insulation and ventilation works, and any conservation-area, listed-building or Article 4 constraints that may apply to proposed external changes. Clear findings and next-step recommendations, distinguishing maintenance, adjustment, component replacement and work requiring separate planning or heritage review.

• Provide the full property postcode, system make and model if known, installation date if known, and whether the system is air-source, ground-source or another heat-pump configuration.
• Describe the symptoms, when they began, controller or warning messages, any recent electrical or plumbing work, and whether heating or hot water is affected.
• Keep the outdoor unit, indoor unit, cylinder, controls, filters and isolators accessible; do not remove covers or attempt refrigerant or electrical work.
• Have installation, commissioning, warranty and previous service records available if they exist.
• If the property is listed, locally listed, in a conservation area or subject to an Article 4 Direction, check the council mapping and relevant heritage guidance before changes to external equipment, openings, finishes or other fabric.
