Furnace Not Working? How to Troubleshoot Common Problems Before Winter

As temperatures start to drop, the last thing you want is a furnace that won’t kick on when you need it. We know how stressful that can feel, especially right before winter weather arrives. While many heating issues require professional attention, there are a few simple checks you can make to better understand what might be going on with your system. Check Your Thermostat Settings Before assuming something is wrong with the furnace itself, it’s worth taking a closer look at your thermostat. Make sure it’s set to “heat” and the temperature is higher than the current room temperature. If your thermostat uses batteries, replacing them can sometimes resolve unresponsive or inaccurate readings. Even a small thermostat issue can prevent your furnace from turning on. Make Sure Power Is Reaching the Furnace Your furnace may rely on both electricity and gas, depending on the model. If it’s not running at all, ensure that the power switch located near the unit is turned on. You can also check your breaker panel to see if the furnace breaker has tripped. Resetting it once may help, but if it trips repeatedly, it’s best to call a professional so the underlying cause can be...

Common Winter Heating Issues and How to Fix Them

Winter in Lincoln, NE, can be beautiful, but when your heating system isn’t working properly, the chill outside can quickly creep into your home. Your heater works hard to keep you warm, but it’s not immune to common cold-weather challenges. Let’s take a closer look at some common winter heating issues and how they can be addressed. Uneven Heating Throughout Your Home If some rooms in your home feel warm while others remain chilly, your system may be struggling with uneven airflow. This can be caused by dirty air filters, closed or blocked vents, or unbalanced ductwork. Replacing filters regularly and ensuring vents are open and unobstructed can often resolve the issue. However, if the problem persists, it may require an inspection to assess your duct system or thermostat placement. Heating System Short Cycling Short cycling occurs when your heating system turns on and off frequently without completing a full heating cycle. This issue can stem from a variety of causes, including clogged filters, a malfunctioning thermostat, or even an oversized unit. Short cycling not only reduces comfort but also increases energy bills and puts unnecessary strain on your system. Addressing this problem may involve a professional assessment to pinpoint...

Understanding Unusual Furnace Noises: Signs, Causes, and Solutions

Unusual noises may be a warning sign that something’s amiss with your furnace. An experienced HVAC technician can diagnose your issue and perform any repairs that may need to be made. Noises Associated With Blower Wheels A noise that sounds like metal scraping on metal could signify that something’s up with your blower wheel, which is the piece of equipment that blows warm air out of the furnace and helps circulate it through the house. Blower wheels are sometimes called squirrel-cage fans. When furnace air filters go unchanged for too long a period of time, dust can begin to accumulate on the blower wheel. This means your blower wheel has to work harder to do its job. As little as one-tenth of an inch of dust on your blower wheel can decrease the overall efficiency of your blower wheel by a whopping 20 percent. When your blower wheel has to work extra hard to do its job, it has a much higher risk of breaking. A scraping sound could indicate a broken blower wheel motor mount or a loose or broken blower wheel. Whining noises often indicate problems with the blower wheel’s belt or motor.
