Though Black Canyon City is notoriously hot in the summer, with temperatures reaching 100 degrees, winters can be chilly. Residents like to stay warm and cozy by turning on their heating systems, yet furnaces can experience many problems that compromise the systems’ performance.
So, what are the most common furnace problems? Can you do anything about them to keep your heating unit running smoothly all winter?
As one of the local providers of heating services in Black Canyon City, AZ, Mountainside Air has the answers. Read on to learn more.
5 Typical Heating Issues and What To Do About Them in Black Canyon City
Furnaces keeping properties warm in Black Canyon City can experience everything from premature component failure to debilitating airflow restriction. Here are some of the most problematic furnace issues, their warning signs, and how to troubleshoot them.
1. Filthy Air Filters
Dirty filters are one of the most common furnace problems, yet they’re easy to overlook. As air flows through heating systems, the filter near the system’s return vent captures airborne allergens and contaminants like dust and mold spores. There’s no denying the importance of air filters in keeping indoor air clean, as filthy filters will restrict airflow and cause debris to accumulate on a furnace’s interior components.
With reduced airflow, your furnace’s heat exchanger may overheat, causing your system to shut down before a heat cycle ends. Your Black Canyon City property might also seem colder than usual, even if the furnace runs. Fortunately, if the air filter is responsible for these problems, all you have to do is replace it.
2. Pilot Light Issues
Ignition and pilot light issues can occur for multiple reasons, such as a clogged flame sensor, a failing thermocouple, or dirty burners. These problems can trigger your furnace’s safety features, all of which may keep the system from firing up.
Addressing ignition problems may be as simple as resetting the furnace and relighting the pilot light. For safety purposes, you should always follow the manufacturer’s instructions when relighting or resetting your furnace.
If your heating unit uses an electric ignitor, ignition problems might be due to a dirty or faulty flame sensor. This component ensures safe furnace operations by shutting the system down if it senses gas but no heat from the flame. It prevents harmful gases from building up inside the furnace.
If your furnace isn’t turning on or is short-cycling due to ignition problems with an electric ignitor, technicians will take these steps:
- Turn off the heater’s power supply.
- Shut the gas supply valve.
- Carefully remove the flame sensor near the burner assembly.
- Use fine-grit sandpaper to remove grime from the sensor without harming it.
- Remove remaining debris and replace the sensor.
3. Thermostat Failures
Sometimes, declines in a furnace’s performance are a sign that the thermostat has a problem. Thermostat malfunctions can take many forms, from incorrect settings to power supply issues.
Anytime your furnace appears to operate inconsistently by turning on and off too frequently or not producing heated air, ensure your thermostat setting is in “Heat” mode. You also want to do the following:
- Set the desired temperature at least five degrees above room temperature.
- Change the batters to ensure the device gets sufficient power.
- Ensure the thermostat is in “Auto” mode.
4. Excessive Noise
Strange noises from your furnace can mean numerous things. For example:
- Squeals could indicate the need for a replacement fan belt.
- Rattling signifies loose panels or other components.
- Grinding may mean the motor bearings need repair.
A professional technician can handle all of these common furnace problems with repairs.
5. Limit Control Switch Problems
Blower malfunctions can trigger issues with the limit control switch, which shuts down the furnace if it gets too hot. A problematic limit control switch may be why your blower fan runs non-stop, even if your thermostat is in “Auto” mode and not its “On” mode.
Replacing a limit switch isn’t something you should do alone. Call a local Black Canyon City HVAC technician.
