Common Heating Problems We Fix
Furnaces and heat pumps can develop a range of issues as they age, especially during heavy winter use. Our technicians work through each problem carefully, explain what’s causing it, and help you understand the safest and most practical way forward. Here’s a closer look at the issues we see most often in Wichita homes.
1. Thermostat Issues
A furnace can only heat properly if the thermostat is sending the right signals. Problems with calibration, wiring, or dead batteries can make your system cycle incorrectly or stop heating altogether.
Helpful tip: Before scheduling a repair, check that the thermostat batteries are fresh and the settings haven’t switched to “cool” or “fan only.”
2. Ignition or Pilot Light Problems
If the furnace won’t turn on, the ignition system is often the cause. Modern furnaces use electronic igniters, while older models use pilot lights that can go out due to drafts, dirt buildup, or component wear.
Ignoring ignition issues can lead to repeated system shutdowns, so it’s best to have a technician diagnose the source right away.
3. Blower Motor Failures
The blower motor pushes warm air through your vents, and when it starts to fail, you’ll notice weak airflow or unusual noises. Overheating, worn bearings, or a failed capacitor are common causes. If the motor stops entirely, the furnace may run but won’t deliver heat through the home.
4. Dirty or Clogged Filters
A clogged filter forces the furnace to work harder, reduces airflow, and can even cause the system to overheat and shut down. This is one of the simplest issues to prevent, yet one of the most common.
Helpful tip: Replace your filter every 1–3 months during heating season to keep airflow steady and improve indoor air quality.
5. Electrical or Wiring Problems
Loose connections, failed relays, and worn wiring can stop the furnace from running or cause intermittent heat. These issues should be addressed promptly, as they can affect both safety and system lifespan.
Electrical components are delicate, so a technician’s inspection is the safest approach.
6. Cracked Heat Exchanger (Safety Concern)
A cracked heat exchanger is a serious issue because it can allow carbon monoxide to enter your home’s air supply. Signs may include strong odors, soot buildup, or repeated system shutdowns. If we confirm a crack, we’ll walk you through your options with safety as the first priority.
7. Airflow Blockages or Duct Leaks
Blocked ducts, collapsed flex lines, or leaking joints can disrupt airflow and make some rooms too hot or too cold. These issues reduce efficiency and place extra strain on the furnace.
Helpful tip: If you notice inconsistent temperatures throughout the home, ducts may be part of the problem.
