We see several common furnace problems in Kansas City.
When colder weather arrives, it’s a good idea to prepare for common furnace problems you may face. We often see the same furnace problems over and over in KC neighborhoods. A little know-how and a few simple tips may help you avoid heating problems this season–or at least better understand what to expect if they happen to you.
1. No Heat at All
Several issues may cause your furnace to stop working entirely. Faulty ignitors are a common culprit, especially if your furnace suddenly shuts off after operating smoothly. Replacing them is a lower-cost repair and is easy for a trained technician to do. Also, if your system hasn’t had regular maintenance, flame sensors can get dirty and keep your furnace from passing its internal safety checks. If you hear multiple clicks but the furnace fails to start blowing warm air, dirty flame sensors may be your problem. Other possible causes include the thermostat, power, or gas supply.
2. Not Enough Heat
Your furnace may appear to be working, but it can’t keep up with the temperatures outside. First, check your air filter. A dirty filter may be clogging your system. Change your air filter to see if it improves performance. It might save you from scheduling a service call.
3. Heat Cycles On and Off
When your furnace continually cycles on and off, you may have a problem with a thermostat setting or airflow. First, check your thermostat settings. A bump or nudge can accidentally move the settings from heating to cooling or even turn the thermostat off altogether. Next, change your filter to see a clean filter will improve airflow and stop the cycling.
4. Thumps, squeaks, or rumbles.
Your furnace is designed to run quietly. If you hear loud noises, you likely have a mechanical issue that needs attention. Depending on the sound, you may have problems with your blower wheel, fan motor, ball bearings, or other parts of your furnace. Schedule a service call right away if your system makes troubling sounds. One of our professional technicians can help you understand what is going on before it causes more damage to your unit.
5. Fan Blows Constantly
If your blower doesn’t turn off, you likely have a problem with your thermostat, blower motor, or limit switch. Scheduling a service call is a good idea when your furnace blows continuously.
6. Lack of Maintenance
Scheduling system checks for your furnace and AC isn’t always convenient, but maintenance goes a long way in preventing breakdowns. We thoroughly clean and inspect your entire unit, priming it for top performance. Besides increasing energy efficiency, our system checks can also find parts that are wearing out before they break down. Many times, a system check can keep you comfortable all winter and help you avoid emergency calls when demand is high.
