Common Furnace Issues
When your Arcoaire furnace isn’t working as expected, it can disrupt your day and leave your home feeling uncomfortable. The good news? Many furnace problems have simple solutions you can handle yourself before calling a professional. Let’s dive into some of the most common furnace issues and how you can address them effectively.
Furnace Not Turning On
Nothing is more frustrating than a furnace that refuses to start. Begin by checking the thermostat. Is it set to “heat” and at the right temperature?
Next, inspect the circuit breaker. A tripped breaker might be the culprit. Reset it and see if that solves the issue.
If these steps don’t work, check the furnace switch—it’s often located near the unit and can accidentally get turned off. Still no luck? The issue might require a deeper look by an HVAC technician.
Inconsistent Heating
Is one room in your home warm while another feels like a freezer? Uneven heating can stem from blocked vents or dirty air filters. Look around your home and make sure vents are open and unobstructed by furniture or curtains.
Dirty filters can also restrict airflow, leading to uneven temperatures. Replace them every 1-3 months depending on how often you use your furnace. If the problem persists, you might need to inspect your ductwork for leaks or gaps.
Strange Noises During Operation
A humming furnace is normal, but loud banging, screeching, or rattling sounds could mean trouble. A banging noise often points to expanding ducts or delayed ignition in the furnace burners. If you hear screeching, it might be a worn-out blower motor belt.
Rattling sounds could indicate loose panels or screws. Tighten any loose parts, but if the noises continue, call a professional to avoid further damage.
Furnace Blowing Cold Air
If your furnace is blowing cold air, start by checking your thermostat settings. Ensure it’s set to “auto” and not “on,” as the latter can cause the fan to blow air even when the furnace isn’t heating.
Another common cause is a dirty flame sensor. This component detects whether the burners are lit. If it’s dirty, the furnace might shut off prematurely, leaving you with cold air. Clean the flame sensor or replace it if necessary.
Also, check if your pilot light is out (for older furnaces) or if the gas supply has been interrupted. A quick inspection can save you a service call.

Checking Power Supply
When your Arcoaire furnace isn’t running, checking the power supply is one of the first steps to troubleshoot the problem. Without sufficient power, your furnace won’t heat your home, no matter how well-maintained it is. Let’s dive into a few essential checks to get your furnace back on track.
Inspecting Circuit Breakers
Circuit breakers are like guardians of your home’s electrical system. If your furnace suddenly stops working, head to your breaker panel and check if the switch for the furnace is flipped to the “off” position. A tripped breaker often means there’s an electrical overload somewhere.
Switch it back to “on” and see if the furnace starts working. If it trips again right away, don’t keep resetting it. This could signal a bigger electrical issue that needs professional attention. Have you experienced frequent breaker trips before? That could be a clue to a recurring problem.
Testing The Thermostat
Your thermostat plays a critical role in controlling your furnace. Start by ensuring it’s set to “heat” mode and the temperature is higher than the current room temperature. Sometimes, a simple adjustment can fix what appears to be a major issue.
If the furnace still doesn’t respond, check the thermostat batteries. Weak or dead batteries can cause the thermostat to malfunction. Swap them out with fresh ones, and see if your furnace kicks back on. Even a dusty thermostat can cause problems—clean it gently with a cloth if needed.
Resetting The Furnace
Every furnace has a reset button designed to restart the system when things go wrong. Locate the button, which is often red and near the blower motor. Press and hold it for about 30 seconds. This simple step can resolve minor glitches in the system.
After resetting, wait to see if the furnace starts functioning. If it doesn’t, double-check for error codes displayed on the furnace or consult your manual. Have you ever tried resetting a furnace only to realize the power was out? It’s always a good idea to confirm the basics first.
Does your furnace still refuse to cooperate after these checks? If yes, it might be time to call a professional. But before you do, ensure all other troubleshooting steps are completed. Sometimes the simplest fixes make the biggest difference.
Airflow Problems
Have you noticed your Arcoaire furnace struggling to heat your home evenly? Airflow problems are a common culprit behind inconsistent temperatures and rising energy bills. Fortunately, many of these issues can be fixed with simple troubleshooting steps that you can handle yourself.
Cleaning Or Replacing Air Filters
Dirty air filters are a top reason for poor airflow in furnaces. A clogged filter forces your furnace to work harder, reducing efficiency and straining the system. Check your filter every 30 days and replace it if it looks dusty or gray.
If you’re unsure about the type of filter you need, refer to your furnace manual or take the old one to a hardware store for comparison. A clean filter doesn’t just improve airflow; it also extends your furnace’s life and lowers your energy costs. Make this quick, 5-minute task part of your regular home maintenance routine.
Inspecting Vents And Ducts
Blocked or obstructed vents can choke airflow. Walk through your home and ensure all vents are open and unblocked by furniture, curtains, or rugs. Even small items like toys or books can reduce airflow significantly.
Next, check your ducts for visible damage like holes or disconnected sections. A small tear in a duct can leak warm air and make your furnace work unnecessarily harder. You can seal minor gaps with duct tape, but call a professional if the damage is extensive.
Checking For Blockages
Obstructions in your furnace’s internal components can also cause airflow problems. Debris, pet hair, or dust can build up in the blower fan or vents inside the unit. Turn off the furnace completely before inspecting these parts for safety.
If you’re not comfortable opening the furnace, contact a technician. A simple cleaning might be all it takes to restore proper airflow. Don’t ignore strange noises coming from the furnace—they could be a sign of blockages or other issues.
Airflow problems don’t have to feel overwhelming. Start with these easy steps, and you’ll likely notice an improvement in your furnace’s performance. When was the last time you checked your air filter or vents? A little effort today could save you from bigger headaches later.
