Helpful Shorewood Furnace Repair
Common furnace issues that require professional repairs often relate to the heat exchanger, pilot, blower, or circuit breaker. For example, your circuit breaker can overload when there are issues with the furnace’s wiring or electrical load. Your heating system’s blower motor is the part responsible for pushing the air into your ductwork. Its significant components are its bearings, belts, and capacitor. Over time, these components can rust, wear out, or begin to malfunction.
Fraying belts can cause raucous screeching, grinding, or screaming sounds that persist throughout the heating cycle. The capacitor is the blower’s source of power, which means it could leave your furnace unable to deliver warm air. You may hear a loud humming sound or notice your system frequently short cycles. Finally, the blower’s bearings reduce internal friction and support the component’s wheel structure. When they fail, they can reduce airflow and quickly increase your energy costs.
The average furnace will cycle between three to eight times an hour, depending on the temperature outside. These cycles will fluctuate in length but can last around five to 10 minutes on average. If your system regularly turns off without meeting your desired comfort level, it likely needs repairs. You should also make sure your furnace isn’t staying on for too long. This warning sign could mean the system is unable to reach your thermostat’s set temperature.
Your furnace’s pilot is key to the system’s ability to start heating cycles. In gas-based systems, this live flame ignites the fuel for the burners. Issues with the gas supply lines or the pilot itself could create problems like delayed ignition. This is when the gas doesn’t ignite immediately and is instead allowed to build up within the system. Watch for any red flags in your flame’s color and strength during the winter. If it’s flickering or turning orange or yellow, call for service soon.
Don’t forget to take into account your furnace’s heat exchanger. This part safely contains the heated combustion gases as they warm your air. Unfortunately, as the system ages, the metal can corrode, crack and develop holes. A bad heat exchanger may cause internal overheating, excessive condensation, and a buildup of soot. You could notice pungent odors around the system as well as strange popping or rattling. A carbon monoxide leak is a significant concern as it could put your family’s health at risk. Exposure to this gas will leave your family susceptible to headaches, dizziness, confusion, and nausea. When your detectors begin going off, it’s best to shut down the system and evacuate the home.
Furnace issues often start small before they manifest into major concerns that require significant repairs.
- Increase in monthly utility costs
- Thumping, banging, grinding, or screeching sounds
- Rotten egg, musty or burning smells
- Lack of home heating
- Poor indoor air quality
