• A lingering smell of gas or an activated carbon monoxide alarm
• Electrical burn odours around air handlers or fuse boards powering HVAC equipment

HEP’s Structured Diagnostic Approach

Precision in heat repair begins with a systematic approach to pinpointing the underlying cause of failure rather than replacing parts arbitrarily. HEP’s process features several critical phases:

1. Visual inspection of the appliance casing, flue routes, condensate pipework, and electrical connections
2. Consultation with occupants to gather operational history, observed symptoms, and any previous repair records
3. Multimeter and manometer testing to verify voltage, resistance, and gas pressures align with manufacturer specifications
4. Flue gas analysis to measure combustion efficiency and CO/CO₂ ratios in boilers or furnaces
5. Refrigerant pressure and superheat readings on heat pumps and air-conditioning circuits
6. Thermal imaging surveys to detect hidden blockages in pipework or cold spots within under-floor heating loops
7. Data logging of control signals from smart thermostats, weather compensation sensors, and building management systems

Data-Driven Reporting

HEP creates a concise yet comprehensive digital report outlining:

• Diagnostic measurements
• Identified faults
• Priority ranking of required repairs
• Recommendations for upgrade options, if beneficial for energy optimisation

Heat Repair Procedure: Step-by-Step

After diagnostics, the heat repair sequence unfolds in a carefully choreographed manner to maximise safety and minimise disruption.

1. Isolation and Safety Checks

Technicians isolate electrical supplies, close fuel shutoff valves, and verify zero pressure or voltage where required. Lock-out tags are affixed to prevent inadvertent re-energisation.

2. Component Access and Removal

HEP’s team follows manufacturer-approved disassembly guidelines. Access panels, burner assemblies, or heat pump service covers are removed without damaging gasketing or insulation. Faulty components are photographed for documentation.

3. On-Site Repairs vs Workshop Overhauls

Lightweight parts such as igniters, sensors, or fan belts are swapped on location. Heavier tasks, like refurbishing a cracked heat exchanger, may necessitate removal to the company’s workshop where specialised welding and pressure-testing equipment are available.

4. System Reassembly and Leak Testing

Replaced components are reseated with new seals or gaskets. Gas joints are checked with leak detection fluid, and refrigerant circuits are pressure-tested with dry nitrogen before evacuation and recharge.

5. Calibration and Commissioning

Technicians calibrate:

• Gas valve modulation curves
• Fan speeds
• Pump flow rates
• Thermostat differentials

Combustion analysis or refrigerant pressure readings confirm the system now meets design specifications.

6. Performance Verification

The entire heating or cooling cycle is monitored to ensure:

• Stable room temperature control
• Correct defrost or condensing cycles
• No abnormal vibrations or noises

An operational log is left for occupants, explaining optimal settings and maintenance intervals.
