Furnace Repair in Anoka MN

The kind of maintenance that you might need for your furnace can depend on the kind of furnace that you have. Furnaces and heating systems can either run on electricity or gas, and each kind can come with a whole set of benefits and complications. Here are some common problems you might see specifically with a gas furnace this winter: furnace repair in Anoka MN

Flipped Gas Valve

One problem that you might notice with your furnace lies in the gas valve. If the valve becomes twisted around by accident or when you are performing a different kind of maintenance, it will prevent hot air from blowing from your furnace at all. If you notice your furnace not blowing hot air, you should make sure to trace the gas line back from the furnace to the gas meter. Here, you should see a valve that appears to be parallel with the gas pipe. This is how you know the gas is turned on. If the valve is perpendicular on the gas pipe, the gas is not turned on. This is a quick fix if you find that your valve is perpendicular, because you can simply turn the valve back to parallel to get the gas back on. However, if this doesn’t fix the problem or your gas valve was parallel to begin with, there might be another problem that your HVAC company in Anoka MN needs to help you solve.

Bad Electric Ignition

Other problems with gas furnaces can depend on how old the furnace is. Older furnaces tend to ignite through a standing gas pilot, while newer furnaces use electric ignition. This kind of ignition can occur in a couple of ways – intermittent pilot, where a high-voltage electrical spark ignites the gas pilot and main gas burners, or hot-surface ignition, where a heating element ignites the gas burner. If there is a problem with the electrical ignition, your furnace might have trouble responding properly to the temperature you set your thermostat to. It could produce too little or no heat, cycle frequently, or blow lots of air from the fan. Your Anoka HVAC contractors are probably the best people to call when you think you might have an issue with the electric ignition for your furnace, as it can be tricky to solve these kinds of problems yourself.

Pilot Light is Out

Standing gas pilots, found in older furnaces, use a pilot light to indicate that the gas pilot and main gas burners are working properly. However, the light can go out due to issues like dirt in the gas tube or pilot burner, a faulty thermocouple, or even due to a strong draft. That’s why it is important to regularly check on the pilot light for your furnace to ensure that it is still lit. Fortunately, it can be fairly easy to relight the pilot light, and it’s also pretty easy to replace the thermocouple if it turns out to be faulty.
