What Happens If Furnace Gas Pressure Is Too Low?
In short, dangerous things can happen if the gas pressure gets too low inside your home’s furnace. If you suspect this is happening to your furnace, contact an HVAC technician in Phoenix, AZ, right away to look into the issues.
Potential problems of low gas pressure in the furnace might include the following:
- Increased energy bills: Your furnace will use more energy when it doesn’t run efficiently. Though it’s not an emergency in the truest sense, increasing electricity and gas bills are a consequence of gas issues that can make your budget feel extra tight.
- Excess moisture: Too much moisture in the furnace will lead to rust and chemical corrosion. If this occurs in the combustion chamber, it could crack. A leak would mean carbon monoxide spilling into your home.
- Poor heat output: If your gas furnace isn’t heating up, it could be due to dipping gas pressure. You may find yourself wondering when the house will feel warm again, even when the furnace has been on all day.
- Incomplete combustion: The lack of gas pressure will inhibit the combustion process and lead to carbon monoxide buildup. Eventually, that gas could escape into your breathing air.
What Causes Low Gas Pressure? Here’s How To Rebalance a Furnace in Phoenix, Arizona
You know what happens if furnace gas pressure is too low. Now, how do you prevent it?
Common Causes of Gas Pressure Issues in Your Furnace
Possible causes of low gas pressure in a furnace include:
- An HVAC technician installed something incorrectly.
- The manifold setting for a gas system would be better in a propane system.
- The manifold is malfunctioning.
- Corrosion blocks the flow of gas.
- Rodents, insects, or birds nested in the off-season furnace and have blocked it.
- Pilot light issues like a flame rollout or delayed ignition interrupt the gas flow.
More Signs the Gas Pressure Is Too Low
Keeping your eye on your monthly gas and electric bills is an easy way to tell if your furnace gas pressure is low. You’ll pay more when the system becomes inefficient. A sudden jump in energy costs is a good indicator that something is wrong with the heating and cooling.
Another good way to tell is to set up a carbon monoxide detector near your furnace. It will sound when it detects the poisonous gas.
Pressure issues also manifest as corrosion on the furnace.
What To Do About Low Furnace Gas Pressure
Don’t wait to find out what happens if furnace gas pressure is too low! If you see a problem, call an HVAC technician before you’re facing carbon monoxide leaks. That gas leak can be lethal for anyone who breathes it in long enough.
Once you call for furnace repairs, your HVAC technician will likely start by resetting the unit to stabilize the gas pressure. Sometimes, the switch gets stuck. However, if that doesn’t work, the technician will then follow these steps to adjust the furnace’s pressure:
- Turn off the gas and electrical supplies to the furnace.
- Connect a manometer to the pressure gauge, and turn on the furnace burner.
- Increase the gas pressure by turning the screw, which should stabilize the gas pressure at the appropriate rate.
Once the gas pressure is steady, the technician will let you know if anything needs repair.
