The gas valve is an essential component of your gas furnace and plays a key function in maintaining a comfortable indoor temperature. In response to commands from the thermostat, this valve controls the flow of gas from the pipeline to the burner in the furnace. A gas valve is opened when the thermostat detects a demand for heat; the gas heater is then ignited, either by a pilot light or an electronic ignition, and the heat is spread throughout each room in your home.

Identifying Issues with Your Furnace Gas Valve

Several indicators might suggest your gas furnace or gas valve is experiencing issues, such as:

  • Heating Inefficiency: A furnace that fails to heat adequately might be suffering from a gas valve that isn’t opening as it should.
  • Gas Odor: The smell of gas in the vicinity of your furnace poses a significant risk, potentially pointing to a leak at the gas valve.
  • Pilot Light Complications: Trouble with keeping the pilot light lit or igniting the burner might trace back to valve problems.
  • Unusual Moisture Levels: Excessive moisture near your furnace or within the venting system can signal a dysfunctional gas valve.
  • Odd Sounds: Sounds that are out of the ordinary upon startup might indicate the gas valve is having difficulty operating properly.

Troubleshooting and Addressing the Most Common Problems with Valves

A few common snags that can affect furnace gas valves include obstructions from dust, dirt or debris, mechanical failures like a jammed or broken valve, and complications with the unit’s electronic controls. Here’s how you can start troubleshooting common issues:

  • Pilot Light Inspection: Verify the pilot light is active and that its flame is robust and properly aligned, as this can hint at issues with gas flow or pressure.
  • Debris Check: Investigate for any blockages that could impede gas movement. This usually means turning off the gas at the main valve for safety prior to any inspection.
  • Gas Pressure Evaluation: Inaccurate gas pressure might inhibit the valve’s ability to open. This assessment should be conducted by a skilled HVAC specialist to ensure precision and safety.
  • Electrical Connectivity Review: The functionality of the valve can be affected by electrical issues, such as disconnected or damaged wiring or faults in the control board. It’s important to inspect for any such problems.

My hot water tank failed on a Friday evening. Had spent some time on Saturday morning calling a number of service companies and Comfort Union was one of the quickest to respond and able to execute the work over the weekend. The gentlemen that showed up were very friendly, completed the work in a timely manner, left no damage and cleaned up after the work was complete. Great experience with Comfort Union!

We strongly recommend that Comfort Union attends to your residential heating, plumbing, and electrical services. Our tank water heater broke down on the weekend. On Monday, we called a few large companies, and all their estimates were on par or above the price point for the following tankless water heaters: Navien NPE-240A2, Rinnai RXP199iN, Rheem CRTGH95DVLN-3, AOSmith ATHR-199X3. During our online search, we encountered a hidden gem: Comfort Union, a small, family-oriented business with competitive and affordable pricing. They strive to adhere to a strict moral code that values integrity, fairness, and straightforwardness. We had the pleasure of meeting Asif, who was patient and took the time to address all our questions, concerns, and needs. He assessed the situation and recommended the most suitable tankless water heater option.We were not pressured to buy products – Asif was genuine and transparent. He used his expertise to guide our decision-making, always considering our needs and best interests. Ultimately, we decided on the Rinnai RX199iN SENSEI® RX Series. This model from Rinnai, a frontrunner in the industry, offers higher efficiencies, higher BTU output, better pairing with existing systems, and forward-thinking technologies. These unique features have truly enhanced our home comfort and reduced our energy bill. Asif and his team were excellent. Their workmanship, craftsmanship, and customer service are unparalleled. With their engineering backgrounds, they combine their vital knowledge to ensure our installation process is of the highest quality and standard. A special thanks to Asif, who worked tirelessly and meticulously to ensure all components were correctly installed and even took extra effort to reposition the water supply line and pipe at no additional cost. These thoughtful additions demonstrate their attention to detail and commitment to customer satisfaction, making us feel valued and important. Their commitment to our satisfaction was evident throughout the process, making us feel truly important. Thanks to their professionalism and expertise, the entire process was smooth and hassle-free. Their service was not only quick and reliable but also very affordable.  This affordability, coupled with their superb customer service, a key factor that sets them apart, will make me use them for all my residential heating, plumbing, and electrical services needs. Our experience with Comfort Union has been nothing short of exceptional. We couldn't be more satisfied!

I recently had the pleasure of working with Comfort Union for three major installations in my home—a new heat pump, a tankless water heater, and a furnace—and I couldn't be happier with the entire experience!Heat Pump Installation:From the first consultation, Comfort Union’s team impressed me with their knowledge and transparency. I decided to upgrade to a heat pump because I wanted to improve energy efficiency and take advantage of both heating and cooling from one system. The team carefully assessed my home’s layout and explained every step of the process, including how the heat pump would function in Calgary’s colder climate. They even took the time to break down the cost savings I could expect over time.The installation was seamless. The technicians were punctual, professional, and clearly experts in their field. They worked efficiently, ensuring that all components were correctly installed, and even took extra care to tidy up after themselves. They walked me through the setup, explaining how to use the system, and answered all of my questions patiently. Now, I enjoy year-round comfort with a system that’s quiet, effective, and eco-friendly!Tankless Water Heater Installation:I also had Comfort Union install a tankless water heater (Rinnai RXP199), and it’s been a game-changer for my household. No more waiting for the water to heat up or running out of hot water during long showers—this tankless system delivers endless hot water on demand!Their installation team was fantastic. They emphasized the importance of proper installation for efficiency and to protect the warranty, which gave me peace of mind knowing I was in good hands. I appreciated that they took the time to explain the maintenance needs to ensure the system stays in top shape for years to come. Plus, they added smart touches like installing a drier filter for extra protection against Calgary’s colder months.Furnace Installation:Lastly, I had Comfort Union replace my old furnace, and wow—what a difference it’s made! They recommended a high-efficiency model based on my home’s size and heating needs, and it has drastically improved my energy bills. The new furnace is powerful yet super quiet, and I can already feel the consistent warmth throughout my house.I can’t stress enough how smooth this installation went. The team was respectful of my space, even laying down mats to protect my floors. They installed a new programmable thermostat and made sure everything was running perfectly before leaving. They also included a comprehensive warranty and provided advice on how to keep the system running efficiently for years.Overall Experience:What I love most about Comfort Union is how they combine their technical expertise with a personal touch. From the friendly office staff to the knowledgeable technicians, everyone I interacted with was professional, courteous, and genuinely cared about my comfort. I also appreciate that they offer full coverage with their installations, including maintenance plans, which makes me feel even more confident in my investment.If you’re looking for a reliable, family-run HVAC company that truly puts customers first, I highly recommend Comfort Union. Their workmanship, attention to detail, and top-notch service exceeded all my expectations. Whether you need a new heat pump, tankless water heater, or furnace, you won’t be disappointed!

Tankless Water Heater: Very happy and impressed with how quickly Asif came out to assess the problem, with his knowledge and the response time to quote and install a replacement unit. No pressure sales and upfront pricing with no surprises. I had a quote from another ‘Rinnai Approved’ company who flip-flopped on the work scope, upgrades and advised on new venting (at great cost) that was simply not needed. The tech (Mo) did a good job removing and installing the new unit and so far the unit has been working great.

I had a great experience with comfort union. Even over the long weekend they answered the phone, and were there the next day to replace my hot water tank. Moe called in the morning to give me an ETA and then a text when he was actually on the way. He was thorough, friendly, knowledgeable and would use this family run business again

Amazing service Asif, Mo and Daryl. Thank you Comfort Union! On Friday evening our hot water tank stoped working. We e- mailed Comfort Union in 30 minutes they called us back. Very professional and friendly staff. Friday evening we had our quote. Very detailed and clear. On Saturday morning they called to see if we have any questions. The price was very reasonable. We booked the service and that afternoon we had a brand new hot water tank installed. We were very pleased and we highly recommend Comfort Union. These three young man were just amazing!

Comfort Union just finished up HVAC work for the secondary suite basement for us in Airdrie, and I gotta say, these guys did a fantastic job. They installed a new Carrier furnace, moved our old Trane to a different spot, and hooked us up with a Lennox AC. Everything was smooth, and they really knew what they were doing.I love that they’re a family business—and really care about their work and their customers. The crew was super friendly and easy to talk to, and they made sure to explain everything along the way. The new furnace and AC are working great, and moving the old unit seemed like no big deal for them.Overall, just a great experience. If you need any HVAC work done in Airdrie, these are the people to call. Can’t recommend Comfort Union enough!

Frequently Asked Questions about a Furnace Gas Valve

How to locate your main gas shut-off valve?

You may typically find the main gas shut-off valve close to your gas meter. You can locate this meter on the outside of your house, usually towards the rear or side, near the spot where the gas line comes into your property. The gas flow can be turned off by turning the shut-off valve, which is often a lever.

In case of an emergency, knowing its location is vital for turning off the gas supply fast.

How to Check if Your Gas Valve Won't Open?

If your gas valve is stuck, you can hear it trying to open by listening for a clicking sound when the furnace turns on; this means the valve is getting the signal to open but is becoming stuck. Although most diagnostic tests, such as examining the valve’s solenoid with a multimeter, necessitate technical knowledge, visual checks for clear indications of damage or obstruction can also be instructive.

What If Your Gas Valve Is Fine But The Furnace Still Isn’t Working?

Problems with the gas valve aside, the thermostat, pilot light, ignition system, or electrical system of the furnace could be to blame if it continues to fail to operate. Make sure the batteries are in good shape, check the thermostat settings, turn on the pilot light (if it’s an older type), and look for any sign of damage or loose wires in the electrical connections.

How Can You Open a Furnace Gas Valve That's Stuck Closed?

Mechanical failure or debris accumulation are two possible causes of a jammed gas valve in a furnace. If your gas valve becomes stuck, you should not try to open it or fix it manually because of the dangers of gas pressure and leakage. An HVAC technician should be hired for this job.

How to turn off the gas shut-off valve to appliances?

You can stop the flow of gas to a certain device by finding its gas shut-off valve. A few feet distant from the appliance, this is often located on the gas line. Direct the valve to the off position by turning it 90 degrees. If a gas leak were to occur in a particular appliance, this would be extremely helpful during maintenance.

How To Check If Your Gas Valve Has Failed?

If you suspect a gas valve isn’t working, there are a few things you may check: whether the thermostat is requesting heat, whether the valve is receiving electricity, and whether the pilot light or ignition system is working. A multimeter test for electrical continuity in the solenoid of the valve will provide a more comprehensive diagnosis of common issues.

Can You Replace A Gas Valve of my Gas Furnace On Your Own?

Handling the gas line and making sure the furnace is safe and working properly after installation are involved in replacing a gas valve. It is strongly recommended that only licensed HVAC professionals perform this work and work on the replacement valve because of the intricacy and hazards involved, such as the possibility of gas leaks or incorrect installation.

Severe safety risks, as well as potential violations of municipal codes and warranties, can arise from do-it-yourself projects.

Conclusion

The furnace gas valve plays a pivotal role in the safety and efficiency of your home heating system. Regular maintenance and professional inspection can prevent common problems and ensure that this crucial component operates correctly.

Should issues arise, understanding the signs of a gas leak or valve malfunction and seeking prompt professional assistance is key to maintaining a safe and warm home. Remember, when it comes to gas appliances, safety and expertise should always be your priority.

Choosing professional help to get gas-powered unit installed or repaired is crucial.
