Troubleshooting Common Furnace Issues
Even with a well-maintained furnace, issues can still arise. Let’s explore some of the most common furnace problems and the steps to diagnose and resolve them:
Insufficient Airflow
If you’ve noticed that your furnace isn’t heating your home as effectively as it once did, a lack of airflow could be the culprit. Dust and debris can accumulate in your ductwork, restricting the flow of warm air.
To check for this, simply place your hand in front of a vent and feel the amount of air coming through. If the airflow seems reduced, it’s time to schedule a duct cleaning. Our HVAC technicians will thoroughly clean your ductwork, ensuring optimal airflow and improved heating performance.
Clogged Air Filters
Another common cause of diminished airflow is a dirty or clogged air filter. Your furnace’s filter plays a crucial role in keeping your indoor air clean and your system running efficiently. Over time, this filter can become overwhelmed with dust, pet hair, and other airborne particles, restricting airflow and forcing your furnace to work harder.
The solution is straightforward: replace your furnace filter every 1-3 months, depending on your usage and indoor air quality. By keeping a fresh filter in place, you’ll maintain proper airflow and reduce the strain on your furnace’s components.
Ignition or Pilot Light Failures
Both older and newer furnaces rely on an ignition mechanism to start the heating cycle. In older models, this is typically a pilot light, while newer furnaces use electronic ignitions. If this ignition system fails, your furnace won’t be able to generate heat.
If you notice your furnace isn’t turning on or cycling properly, the ignition or pilot light could be the culprit. Our technicians can inspect the system, clean the components, and make any necessary repairs or replacements to restore reliable ignition.
Blower Motor and Belt Issues
The blower mechanism plays a critical role in distributing the heated air throughout your home. If this system experiences problems, you may notice your furnace isn’t blowing hot air as it should.
One common issue is worn-out blower bearings, which can cause a distinct scraping sound. Another potential problem is a malfunctioning blower belt, which may result in a high-pitched squealing noise. In either case, our HVAC experts can quickly diagnose the issue and replace the affected components to get your furnace back in top working order.
Heat Exchanger Failures
The heat exchanger is the heart of your furnace, responsible for transferring heat from the combustion process to the air that’s circulated through your home. Over time, these heat exchanger tubes can develop cracks or other malfunctions, compromising their efficiency and potentially creating safety concerns.
If you notice that the air being pushed through your vents isn’t as warm as it should be, a heat exchanger problem could be to blame. Our technicians can thoroughly inspect the heat exchanger and recommend the best course of action, whether that’s a repair or a full replacement.
Thermostat and Electrical Issues
While many furnace problems are directly related to the system itself, issues can also arise with the thermostat or the electrical components powering the furnace. A malfunctioning thermostat may send incorrect temperature readings to the furnace, causing it to under- or over-perform. Electrical problems, such as tripped circuit breakers or faulty wiring, can also disrupt the furnace’s operation.
If you’re experiencing inconsistent heating or your furnace is not responding to thermostat commands, our team can investigate the electrical and control systems to identify and resolve the issue. This may involve thermostat recalibration, circuit breaker resets, or more extensive electrical repairs.
