Expert Heating Maintenance & Safety Tune-Up for Blackstone Properties
Blackstone winters regularly bring nighttime temperatures into the teens. For homes relying on heat pumps with electric backup or dual-fuel systems paired with LP gas furnaces, a stuck reversing valve or failed emergency heat sequencer can cause immediate indoor chill or dramatic electric bill spikes.
Our Blackstone shop carries OEM heating sequencers, dual-fuel control boards, igniters, and calibrated combustion analyzers. We diagnose the true electrical or mechanical fault and provide written options before any repair proceeds.
Flue Gas Combustion Analysis
We insert calibrated combustion analyzer probes into the exhaust flue to measure oxygen, carbon monoxide, carbon dioxide, and stack temperature. These numbers reveal whether fuel is burning cleanly or creating soot and dangerous CO levels inside the cabinet.
Burner Assembly Cleaning & Flame Sensor Service
Oxidation on the flame sensor is the #1 reason furnaces fail to stay running in late fall. We clean the flame sensor, vacuum burner compartments, clear burner crossover ports, and verify smooth, quiet ignition across all burners.
Blower Motor & Electrical Safety
Restricted airflow causes furnaces to overheat and trip high-limit switches. We test blower motor capacitor microfarads, check motor amp draw, verify belt tension where applicable, and inspect electrical wiring terminals for heat discoloration.
