Overview of Furnace Gas Valve Replacement

The gas valve in your furnace regulates the flow of natural gas into the combustion chamber of your gas or propane furnace. When it’s not working properly, the furnace will fail to light and produce no heat. While the gas valve may be the ultimate reason your gas furnace is not working, it could also be a result of another failing part like the circuit board or any of the other failsafe circuits inside the furnace.

This HVAC repair page of Costimates helps you learn more about the factors that affect the cost of replacing a furnace gas valve.

Furnace Gas Valve Cost Factors

These factors will help you narrow down the cost for replacing a gas valve in your home furnace.

  • Furnace is Covered by Warranty or Not: If your gas furnace is less than 5 years old, 10 years on many models, the gas valve can be replaced under your manufacturer’s warranty. While the cost of the replacement part is covered, the labor to install it is usually your responsibility.
  • Stages of Heating: Two-stage and modulating capacity gas valves are more complex, so cost more than single-stage units.
  • Smart Technology and Monitoring – Newer furnaces, namely those built in the last 10-15 years, have quite a bit of smart technology built in to them. Some of that technology measures gas flow at the valve and bases performance on various measurements. If you have an intelligent or communicating furnace, the vale is like to cost a bit more.
  • Propane Conversion: Some gas valves are assembled with a nozzle sized for liquid propane (LP). Others must have a natural gas (NG) nozzle replaced with an LP valve at installation, which raises the labor cost by $25-$50.
  • Brand or Universal: The gas valve on most furnaces can be replaced with a less-expensive part from Honeywell, White Rodgers or other universal part. A few furnaces require brand parts. Lennox is one brand with higher-than-average replacement parts costs for this reason.

Some companies use flat-rate pricing for repairs. Others will want to know where the furnace is located and how easy it is to access before quoting you a price. These factors might apply:

  • Furnace Access: Furnaces in attics and crawlspaces are harder to work on, so repair costs are higher. Some furnaces have gas valves that require more labor than average to replace, which also leads to higher prices.
  • Where you Live: Labor rates for furnace repair reflect the cost of living in the region. It’s typically highest in the Northeast and Northwest. Next are other major metropolitan areas. Rural areas often have lower labor rates.

Installation Time

Replacing a valve is usually a straightforward job. It becomes more time consuming as furnace access gets more difficult.
