A furnace ignition failure is a common winter issue here, often caused by a faulty ignitor, flame sensor, or gas valve. It's a serious problem that leaves your home cold.

Absolutely. Duct leaks in attics, basements, or crawlspaces are a frequent cause of poor airflow and high energy bills in older Pittsburgh homes. Our technicians use specialized tools, like pressure tests and thermal imaging, to pinpoint leaks you can't see. We then seal the ducts properly to ensure all the warm or cool air from your system is delivered efficiently to your living spaces.

The best defense is proactive care. We recommend an annual furnace tune-up in the fall and an AC check in the spring. This service includes cleaning critical components like the flame sensor and ignitor, checking for early signs of duct issues, and ensuring safe operation. This neighborly maintenance helps prevent unexpected breakdowns during extreme weather and keeps your system running efficiently year-round.
