The cost to replace a gas fireplace valve is $300 to $500 on average, including a full fireplace inspection and diagnostic tests. The total cost depends on the valve brand and fireplace accessibility.
The gas valve on a furnace opens or closes to regulate the gas flow to the pilot light and burners. A properly functioning gas valve is necessary to stop gas leaks and maintain indoor temperatures.
Furnace gas valve types Type Features Gas chain valve systemGas valves must be compatible with the furnace’s blower-motor type:
Single-stage blowers have one high-heat setting only.
Two-stage blowers have either low- or high-heat settings.
Modulating blowers have variable heat settings for precise temperature control.
If a furnace gas valve is bad, there will be no warm air coming from the furnace, or it will shut down completely.
Faulty gas valves are a major safety concern. Contact an HVAC technician to test the valve and diagnose the source of the problem.
Some furnace gas valves are interchangeable between propane and natural gas models, depending on the furnace brand, location, type, and local building codes.
Tell an HVAC pro the exact make, model, and size of the existing valve to get the best recommendation for compatible parts.
Replacing a furnace gas valve takes 30 to 60 minutes on average or up to 2 hours for hard-to-access locations like crawlspaces and small attics.
Buy a furnace gas valve from Amazon, Walmart, or HVAC distributors and service companies for the widest selection.
Buying directly from the manufacturer typically costs more but ensures an exact match.
Before hiring a furnace repair service near you, be sure to:
Compare at least three estimates.

A gas furnace offers an excellent and cost-effective form of heating your home–as long as it is working right. There is a lot that can go wrong, from a thermostat malfunction to problems with the heat exchanger, blower motor, a circuit board, a control board, a flame sensor, or igniter.
One of the most important parts of a furnace that needs to be kept in good working order is the gas valve. It may be the reason why your furnace won’t turn on. What happens when a gas valve breaks? A quick furnace fix is needed, and the part either repaired or replaced.

GET ESTIMATESReplacing the gas valve on your furnace can cost anywhere from $300 to $750 dollars. This includes the part itself and the services of an HVAC professional.
The valve itself can range from a cost of $90 to the mid $200s on the high end, depending on the manufacturer. Saving on labor can help you, but only if you know what you are doing around an expensive and potentially dangerous home system. In other words, be careful if you decide to DIY this project!
Furnace repair or replacement can add up. To keep your furnace in top working order, here are some basic tips for furnace maintenance from the US Department of Energy:
A functioning gas valve is one of many factors in an efficient heating system, along with clean and tight ductwork, and furnace parts like a thermocouple, draft inducer, or control valve.
Fortunately, a gas valve is a fairly common furnace repair that doesn’t have to break the bank. What are your options? Let’s take a closer look.
This is where the bulk of your furnace cost will be, whether you are replacing a gas valve or any other part. We estimate you can save $200 – $500 by installing a gas valve yourself if you are out of the manufacturer’s warranty and don’t have a home warranty. Just be sure you know what you are doing and can do the installation safely.
Otherwise, hiring an HVAC company with a solid reputation is the way to go for installation. Compare HVAC system labor rates to get the best deal. If you have a home warranty, you will automatically have access to the warranty provider’s vetted HVAC contractors.
Furnace repair costs can be tricky. There are a lot of complicated parts jammed into a compact space. Like many parts in a gas furnace, the gas valve can sometimes be repaired. In some cases, just a good cleaning is what is needed. But if an actual repair is needed, often the cost of the repair is so similar to replacement costs that it makes just as much sense to get a new, well-functioning gas valve instead of repairing the old one.
A gas valve as a replacement part can be pricey – over $200 in some cases. Add to that the labor costs and, as we mentioned above, the cost can range from $300 – $750.
And if discovering a problem with a gas valve leads to discovering bigger problems, the replacement of the whole system with a new furnace might be necessary. In that case, be sure you have the right permits from your local government.
A warranty for a natural gas furnace from the original equipment manufacturer (OEM) like Lennox, Goodman, Bryant, Honeywell, Amana, or Trane can be helpful but limited. For instance, a Trane registered warranty will cover parts such as a gas valve or pilot light, but will not cover the labor it takes to install the valve.
So a new system is great, but be sure to understand the limitations of the manufacturer’s warranty. And make sure you mark a calendar to know when the warranty runs out or you become responsible for the full cost of repair or replacement of a gas valve or other furnace part.
A home warranty will cover parts and labor for the repair or replacement of a furnace gas valve. There will be exclusions depending on the home warranty company you work with–such as exclusions for improper maintenance or mismatched parts or systems.
You’ll need to factor in the annual cost of a home warranty–which tends to run around the same cost as the professional replacement of a gas valve alone–along with the service call fee–which can be anywhere from the mid-$60s to $125 depending on the type of home warranty plan and the provider you choose. For instance, AHW has a policy premium that runs around $475 with a flat $75 service call fee. Or American Home Shield has a Systems Plan for around $420 and a service call fee between $75 and $125 with a lower premium depending on the service call fee.
A home warranty can provide protection for your furnace–when things like a gas valve break down–and provide peace of mind for other systems and appliances in your home.
Here is a diagnostics video that might come in handy when you take a look at your gas valve to figure out if it should be repaired or replaced:
With a DIY approach, the labor costs are limited to your time. So if you have some basic tools for HVAC repair handy, you might be able to save some money and replace that part yourself
Unless you have some training in heating and air conditioning systems, it might be a better choice to leave furnace gas valve replacement or repair to the professionals. It may not be the most technically challenging repair on your furnace, but if you don’t have the experience, it’s worth the expense.
