3 Signs Your Furnace Has a Faulty Gas Valve
A faulty gas valve is one of the most common issues in aging furnaces. While it doesn’t pose a significant problem in warmer seasons, a failing valve can affect your heating system’s ability to warm your home in the winter. This can affect how you prepare your HVAC system for cold weather.
Inspecting your furnace’s gas valves is crucial so you know when to take proper action and replace parts. Continue reading to learn the three signs your furnace has a faulty gas valve.
Unfortunately, a failing gas valve can’t prevent gas from leaking into the surrounding air. Coupling gas leakage with sparks from old dryers, candles, or an ignition source puts your well-being at risk.
Additionally, gas is a harmful emission that, when inhaled, can cause various health issues. If you smell gas and suspect it is coming from a faulty gas valve, open the nearest window to ventilate the area, and reach out to a professional HVAC company to evaluate the potential damage.
Water and Moisture
In some instances, a heating system might be next to water pipes or washing machine components. Sometimes, a burst pipe or excess moisture can cause rusting and erosion, resulting in damage and inconsistency in operation.
Faulty gas valves enable the furnace to heat the home and power other gas components, like a stove. If there are several valves not performing, it may be a sign of a more significant underlying issue that can cause the furnace to enter a total shutdown phase, otherwise known as “ignition lockout.”
Knowing the signs your furnace has a faulty gas valve helps you keep tabs on your unit and measure output to ensure equipment functions properly. Conversely, it would help to contact an HVAC technician to evaluate your furnace every six months and address concerns.
