When your furnace starts giving you trouble, don’t rush to call a professional just yet. Trying a few simple DIY fixes can sometimes solve the problem and save you both time and money.
Start by checking your thermostat settings and consider changing your air filters. But what if these steps don’t fix the issue? No need to worry. This guide provides you with the essential knowledge to address common furnace issues effectively.
So, before dialing for help, let’s go through some quick solutions that might get your furnace working smoothly again very quickly.

The Furnace isn’t Turning On
If your furnace doesn’t turn on, check the settings on your thermostat. Make sure you set it to ‘heat.’ Sometimes, if there’s a problem with the thermostat, it won’t start the furnace. Adjust the thermostat settings so the temperature is higher than the current room temperature. This action should start the heating cycle.
Next, check the electrical connections. If these connections are loose or damaged, your furnace might not work properly. Always turn off the furnace’s power before you start checking the wires. If you’re experiencing this issue and need reliable assistance, consider contacting Anderson Air.
This is for your safety. Check for any wires that are frayed, connections that look burnt, or other damage. If you find any problems, it might be best to call a professional to fix or replace the damaged parts.
No Heat Output
No heat output from your furnace can be quite troubling, often indicating something is wrong with the heating system. When you notice no heat, check your thermostat and air filter.
First, make sure the thermostat is on heat mode and set to a temperature above the current room temperature. If everything looks good with the thermostat, the next suspect might be a clogged or dirty air filter. A dirty air filter can block airflow, making your furnace overheat and shut off to avoid damage.
Try changing the air filter to a new one and see if that fixes the problem. If you still have issues after trying these steps, it might be wise to contact a professional HVAC technician to look into the problem and repair it efficiently.
Strange Furnace Noises
When you hear unusual sounds like clanking or humming from your furnace, it usually means something is wrong. You shouldn’t ignore these noises because they can lead to bigger problems later. Regular maintenance can help mitigate these issues. Look for any loose parts; they might be causing rattling or vibrating noises. Make sure to tighten all screws and bolts. Also, applying lubricant to moving parts can help them run smoother and quieter.
Another important aspect to consider is how well the furnace area is insulated. Proper insulation can help to keep the noise down. You can use materials like foam or rubber to cushion the space between the furnace and the structures around it.
This helps to soak up vibrations and lower the noise level. If you still hear noises after you’ve done all the maintenance and insulation, it might be time to call a professional technician.
They can determine the deeper issue and fix it before it gets worse. Always pay attention to odd sounds from your furnace; they often indicate something isn’t right.
Uneven Heating in Rooms
To fix uneven heating in different rooms, first, look at how your furnace sends air around and check for anything that might be blocking air flow. Make sure that all air vents are open and nothing like furniture, curtains, or carpets is covering them. This will help the air move better.
Next, check your thermostat. Sometimes, it doesn’t show the right temperature, which can cause heating problems. Set your thermostat as the maker suggests so it can more accurately measure the room’s temperature.
Also, look at the insulation of your ductwork. If the ducts aren’t well insulated, heat can be lost when the air moves through them. Look for any holes, leaks, or places where insulation is missing. Fixing and adding insulation to the ducts can help keep the heat even in your home.
Constantly Running Furnace
If your furnace keeps running constantly, first check the air filter. A dirty air filter makes it hard for air to pass through, forcing the furnace to work extra hard to heat your home.
If the filter looks good, the problem might be with your thermostat. Sometimes, a broken thermostat keeps the furnace running without stopping because it fails to signal that the room is already warm enough. You could try changing the batteries of the thermostat or adjusting its settings to fix this.
Another reason why your furnace may not stop running could be a problem with the fan limit switch. This switch controls the blower’s on and off times; if it’s not working right, the blower might keep going non-stop. Adjusting or changing this switch could be the solution.
Regularly maintaining your furnace and changing the air filter on time can stop it from getting blocked. Also, making sure your thermostat works correctly can prevent your furnace from running all the time. If you try these simple solutions and still have issues, it might be time to call a professional technician for more help.
Pilot Light Keeps Going Out
When you find that the pilot light on your furnace keeps going out, start by checking the area around the pilot light for any blockages. Make sure no draft or debris is affecting the pilot light’s flame. If everything seems clear but the pilot light still fails to stay lit, consider these two common problems: a possible gas leak or a faulty thermocouple.
First, if you think there might be a gas leak, it’s critical to take care of this right away due to safety concerns. You should call a professional to check the furnace and the gas lines to avoid any dangerous situations.
The issue might be with the thermocouple, a safety device that checks whether the pilot light is on. If it’s not working properly, it might wrongly tell the gas valve to shut off, which would put out the pilot light.
If this is the problem, replacing the thermocouple should fix it and help keep your pilot light on without further trouble.
