What is Furnace Repair?
Furnace Repair is the technical restoration of your heating system’s ability to burn fuel safely and distribute warmth. The most critical part of this service is inspecting the heat exchanger—a metal wall that keeps poisonous flue gases separate from the air you breathe. We also service the pilot light or electronic igniter, which starts the fire, and the "limit switch" that prevents the unit from overheating.
Our technicians focus on the combustion process, ensuring that the gas pressure is correct and the exhaust "flue" is venting smoke safely out of your home. By keeping these parts in sync, we ensure your furnace provides "hot" heat even during an Alabama ice storm.
When is it Necessary?
You should call for a furnace repair if you smell "rotten eggs," which indicates a dangerous gas leak, or if your carbon monoxide alarm goes off. In older homes across Mountain Brook and Vestavia, metal fatigue can cause the heat exchanger to crack over time as it expands and shrinks.
If your furnace is making a loud clicking sound but won't start, it often means the igniter is failing or the gas valve is stuck. You might also notice a yellow or flickering pilot light instead of a steady blue flame, which is a sign the burner is dirty or lacks oxygen. If the unit is blowing dust despite a clean filter, it may have a cracked internal seal that needs immediate attention.
What is Required?
A safe and professional furnace repair requires specialized sensors and a deep understanding of local building codes. We use sensitive electronic "sniffers" to detect even tiny amounts of carbon monoxide, the "invisible killer" that can cause flu-like symptoms.
Our team also performs a "static pressure" test to see if your ductwork is too small, a common issue in historic areas that causes furnaces to overheat. We handle the documentation for Spire gas rebates, which can help cover the cost of upgrading to high-efficiency components. Every repair is finished with a safety check of the chimney or vent pipe to ensure no smoke is backing up into your living space.
