Thomas Lily Plumbing Heating and Cooling: Expert HVAC Repair Serving Pittsburgh, PA 15218

Yes, a furnace ignition failure in winter is a serious concern. Not only does it leave you without heat, but it can also indicate issues like a faulty gas valve or heat exchanger, which may lead to carbon monoxide risks. We treat these as priority service calls. Our technicians will safely diagnose the ignition problem—whether it's the pilot light, electronic ignition, or a safety sensor—and perform the necessary repair to restore safe, reliable heat to your home.

Our HVAC system maintenance service is crucial for Pittsburgh winters. We perform a thorough inspection, cleaning the burner assembly, checking the heat exchanger for cracks (a primary source of CO leaks), testing safety controls, and ensuring the ignition system is functioning correctly. This preventative care significantly reduces the chance of sudden ignition failures, improves efficiency, and most importantly, helps identify potential carbon monoxide hazards before they become dangerous.

For complete home safety, we recommend having all gas lines and appliances inspected. Our gas line installation and repair service ensures your furnace, water heater, and stove are receiving gas safely and efficiently. A small leak or improper connection on any appliance can be a hazard. During a visit, we can check connections, test for leaks, and ensure proper ventilation, giving you peace of mind for your entire home's gas system.
