Poor/Lack of Maintenance

A lack of adequate maintenance is undeniably the leading cause of a heater not working. Every day, we get busy and forget all about our HVAC system until we experience issues or breakdowns. Poorly maintained heaters are prone to more breakdowns and increased energy consumption. It is crucial to schedule regular maintenance on your furnace to guarantee its longevity and efficient operation. Experts recommend you get a professional heater tune-up during the fall, right before the winter comes in full force. If you haven't already, the licensed HVAC technicians at AVU Heating & Air are here to help you. Call us today for all your heater maintenance needs. 

Thermostat Issues

Thermostat issues could also cause your heater to stop working when you need it the most. The primary function of your HVAC thermostat is to regulate the amount of heating being generated by your furnace. Although most modern thermostats boast solid reliability, they eventually develop problems with time. Thermostat problems can be caused by various issues, from dirt accumulation, electrical issues, battery problems, and improper settings to improper installation. Regular maintenance, such as cleaning and ensuring proper wiring, can help prevent breakdowns. 

Overloaded Motor

Heater motors can become overloaded due to various reasons, such as excessive dust, debris accumulation, or a lack of proper maintenance. When the motor is overloaded, it can result in overheating and ultimately cause the heater to stop working. To prevent this issue, have an AVU Heating & Air professional clean and maintain the motor.

Clogged/Dirty Air Filter

Another common culprit of a heater not working is a clogged or dirty air filter. With time, air filters get dirty from accumulated dust, debris, pet dander, and other particles in the air. This buildup restricts airflow and can lead to reduced efficiency or even overheating of the heater's components. Regular maintenance and cleaning or replacement of the air filter is crucial to ensure the proper functioning and longevity of the heating system.

Dead Blower Capacitor

The blower capacitor in a heater helps start and regulate the blower motor. When the capacitor fails or becomes "dead," the blower motor might not start or operate efficiently, leading to a heater not working. Symptoms of a dead blower capacitor include the heater not turning on or running intermittently. Replacing the capacitor is necessary to restore proper functioning.

Low Refrigerant Levels

If you are using a heat pump to heat your home, low refrigerant levels can significantly impact their performance. Low levels could be due to leaks or insufficient initial charging. When the refrigerant levels are low, the heater might struggle to produce sufficient heat, resulting in poor heating or complete failure. Minimal refrigerant levels could also cause the compressor to overheat and break down. It is crucial to regularly inspect your unit and increase the refrigerant charge once you notice the heat strips are coming on too frequently.

Faulty Ductwork Installation and Design

Sometimes, your heater isn't working due to faulty ductwork installation. Poorly designed or installed ducts can lead to leaks, blockages, or inadequate airflow, causing the heater to work harder than necessary. This problem can also result in uneven heating or a complete shutdown of the heating system. Unfortunately, many unlicensed installers opt to cut corners when sizing ducts or installing them. Hire a certified HVAC professional to design and properly install your home's ductwork and prevent heat not working in the house.
