Furnace systems are essential for heating in many homes, but like any mechanical equipment, they can encounter problems. Here are some of the most common furnace repair issues:
- Ignition Problems: Frequent ignition failures calls for furnace repair. Ignition issues often result from faulty thermocouples or pilot lights that need cleaning or replacement.
- Lack of Heat: If your furnace is running but not producing enough heat, it could be due to a malfunctioning thermostat, low water levels, or even those airlocks in the system.
- Strange Noises: Unusual noises like banging, gurgling, or whistling can indicate air in the system, kettling (boiler overheating), or pump issues.
- Leaking or Dripping: Water leaks around your boiler are a sign of potential trouble. Pressure problems, corrosion, or a faulty relief valve may cause leaks.
- Boiler Cycles On and Off Frequently: Short cycling can result from issues with the thermostat, low water pressure, or air in the system. This not only wastes energy but can also result in premature wear and tear.
- No Hot Water or Heating: If you’re experiencing a lack of hot water or heating, the issue could be a faulty diverter valve or a malfunctioning circulator pump.
- Frozen Condensate Pipe: During colder months, the condensate pipe of a condensing boiler can freeze, causing a blockage and boiler shutdown.
- Thermostat Problems: Inaccurate or unresponsive thermostats can lead to uneven heating or erratic boiler performance. Calibrating the thermostat can often resolve this issue.
