Advanced Diagnostic Tools and Techniques
Today’s heating systems integrate complex electronics that require precise troubleshooting.
Combustion analysis
Technicians insert digital probes into flue outlets to measure oxygen, carbon monoxide, and stack temperature. Data reveals incomplete combustion, allowing proactive repair of fuel and air imbalances.
Infrared thermography
Thermal imaging cameras detect temperature anomalies inside walls and ducts, helping locate hidden leaks, blockages, or insulation gaps that exaggerate heating loads.
Additional resources—such as ultrasonic leak detectors, digital manometers, and Wi-Fi data loggers—ensure every component operates within manufacturer specifications.
Indoor Air Quality Integration with Heat Repair Services
Comfort extends beyond temperature control. During heat repairs, HEP evaluates indoor air quality (IAQ) to reduce respiratory irritants.
- HEPA filtration upgrades for allergy relief
- UV-C germicidal lamps to inhibit microbial growth on coils
- Whole-home humidity balancing to limit mold proliferation
