Heater Troubleshooting tips for Homeowners

Even in the warm climate of the Huntsville, TX, area, you need a functioning heater to keep your family warm. An emerging issue with your heating system isn’t just a comfort issue, it’s a safety risk. At WA Air Conditioning, we’re proud to help our friends and neighbors keep their essential furnaces and boilers in good working order. If you run into furnace problems, here are some ways you can troubleshoot.

Basic At Home Heating Maintenance

For any machine, efficient operation is a result of good maintenance, and furnaces are certainly no exception. Here’s a few simple steps you can take to keep your furnace in good working order.

  • Check the power supply. Look for blown fuses, tripped circuit breakers and other electrical issues that could be interrupting the flow of power to your furnace. Check the power cords for any visible corrosion, too, and of course, make sure the unit is turned on.
  • Often, a reset is all it takes to resolve an intermittent issue. Before hitting the reset button, give the unit 30 minutes to cool down. Repeat up to three times.
  • Make sure your thermostat is set properly. It’s very easy to bump the thermostat, accidentally turn it way down and wonder why you aren’t getting any heat.

Some Common Heating Problems

All furnaces are somewhat vulnerable to a few very common issues. In many cases, those issues can be resolved with quick home maintenance steps.

Cycling On and Off: If your furnace shuts off and turns back on very frequently, a dirty air filter is most likely to blame. Change or clean the filter as necessary and see if that fixes the problem. Another possible cause is trouble with the blower motor; a little lubrication goes a long way toward fixing that problem.

Noisy Operation: Furnaces tend to make two noises: a high-pitched “squealing” sound and a lower “rumble.” Squealing is usually a sign of a slipping belt or poorly lubricated motor; if necessary, tighten the belt and put a little light-weight oil on the motor’s moving parts. If the rumbling comes with the burners off, there’s likely an issue with the pilot light, which you can adjust manually. If it occurs with burners on, cleaning the burners will probably resolve the issue.

Insufficient Heat: Once you’ve confirmed that your thermostat is set properly, there are three possible causes of this issue. One, again, is a dirty air filter, which should be replaced as soon as possible. Sometimes, dirty burners also reduce heating efficiency. A final possible cause is obstructed air flow to the combustion air chamber; without enough oxygen, your furnace can’t really burn. Make sure there’s plenty of air entering the furnace and see if that resolves the problem.
