Heritage technician inspecting heating system

Your furnace’s gas valve controls how much gas flows to its pilot light and burners, making it an extremely important component of your heating system. If your furnace is not producing heat, a faulty gas valve could be the problem.

A faulty gas valve is frustrating at best and dangerous at worst, requiring the help of a professional if you are noticing issues with your furnace. At Heritage Home Services, we will have your furnace running smoothly and safely to keep you warm during those winter months. 

Signs of a Faulty Gas Valve 

A Gas Leak 

This is a matter that needs to be resolved as soon as possible, as this will pose a health risk to you and your family. A gas leak may also cause damage to your property, something as little as a spark could break out into a fire. 

Complete Shutdown of Your Furnace 

It’s difficult to pinpoint the exact cause of a furnace shutting off, as there could be a multitude of reasons. To get a correct diagnosis, it’s best to contact a certified HVAC technician. We will be able to find the issue and replace your gas valve if necessary.

Your Furnace is Flooded

In the instance that your furnace is submerged in water, you will want to have an expert technician evaluate the system and its components. Repair or replacement of parts may be necessary to keep the system running safely and reliably.

If the valve was exposed to water, it can malfunction and you don’t want to put yourself at risk, even if a little bit of water has seeped in. 

Why is a Furnace Gas Valve Important?

Having a functioning gas valve prevents your health and safety from being at risk. The gas valve is a critical component of your system. It regulates the flow of fuel into the system at the proper times.

Heating systems do have built-in safety features that will not let the system run if any of the safety measures are not within proper range. The system will default to an off condition rather than attempt to run unsafely.  Likewise, the proper adjustment of a gas valve has a direct impact on the lifespan of the system as well as your gas consumption.  (An improper adjusted gas valve can cost you over 10% more while adding stress to your system.)

We do a digital combustion analysis on every system we work on to ensure your system is running safely and efficiently.
