Expert Furnace Maintenance 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.
Burner & Flame Sensor Cleaning
Dust, pet hair, and oxidation coat burner ports and flame sensors over time. A dirty flame sensor will fail to detect the flame, causing the furnace to shut down repeatedly. We remove, clean, and inspect burner assemblies to ensure smooth, quiet ignition.
Heat Exchanger Camera Inspection
The heat exchanger keeps deadly exhaust gases separate from the air your family breathes. During maintenance, we inspect heat exchanger cells with high-definition borescopes to check for microscopic cracks, rust pitting, or flame impingement before they become dangerous.
Gas Pressure & Safety Control Testing
We test gas supply and manifold pressure using digital manometers, adjust pressure to factory specifications, and test safety limit switches, rollout sensors, and draft pressure switches to ensure fail-safe operation.
