In the event of a heating breakdown, panic is often the first reaction. Fortunately, more often than not, the problem is caused by a simple issue, such as a clogged HVAC filter or a drained thermostat battery. Before you imagine the worst-case scenario or call our heating repair experts in Marble Falls, Texas, try these troubleshooting tips.

Thermostat Troubleshooting

If your heater is behaving unexpectedly, the thermostat is the most likely culprit. Before attempting any other step, double-check your fan and heater settings. If the display isn’t functioning properly, the battery may need replacement. For digital models, if it’s not hardwired, it’s a good idea to replace the batteries once a year at the beginning of the heating or cooling seasons. Remember that most systems have a five-minute delay following power interruptions. This is typically indicated by a flashing heat icon.

Electrical Faults

Electrical problems are another possibility, especially if the system is blowing cold air or you can’t feel any air coming from the vents. Try resetting the circuit breaker. You may want to check the emergency shutoff switch that’s located near the side of the furnace. The problem could also be caused by a faulty thermocouple, pilot light or ignition switch. In that case, have a professional inspect the system.

Problems Related to Clogged HVAC Filters

Clogged HVAC filters can also wreak havoc on your heating system. If your furnace isn’t providing much heat or if the system shuts down unexpectedly, start by replacing the air filter and making sure that all of the vents are open and unobstructed. In addition to restricting the airflow and causing overheating, dirty filters increase the system’s energy use by 5 to 15 percent, which can inflate your utility bills unnecessarily.

These simple steps can correct many heating problems. If you’re unable to resolve the issue, you can learn more about our heating repair services online or by calling Clendennen Services AC & Heat at 830-282-4337.
