Highland Heating & Air Conditioning - Pittsburgh's Experienced HVAC Services

Older homes and aging HVAC systems common in Pittsburgh can develop cracks in heat exchangers or have blocked vents, leading to dangerous carbon monoxide leaks. Our expert technicians perform detailed furnace inspections using specialized equipment to check for CO leaks, ensure proper venting, and verify safe operation. We recommend annual safety checks, especially before winter, to protect your family from this silent hazard.

In our climate, a frequent culprit is a dirty or faulty flame sensor. Over time, soot and corrosion can prevent it from detecting a flame, causing the system to shut down as a safety measure. We clean or replace the sensor as part of our furnace repair service. We also check ignition controls, gas valves, and thermocouples—all common failure points in winter—to get your heat reliably restored.

We recommend a pre-winter tune-up that directly addresses Pittsburgh's common issues. Our service includes cleaning the flame sensor and burners, checking the heat exchanger for cracks (a source of CO), testing safety controls, and ensuring proper ignition sequence. This proactive maintenance reduces the risk of no-heat emergencies on the coldest days and improves your system's efficiency and safety for the entire season.
