A central heating system uses either a boiler system or furnace as the main heating appliance to heat a home during cold winter months. The system warms the air that is circulated in a home via a series of air ducts. However, lack of maintenance and malfunctioning of components can cause a central heating system to operate inefficiently. Therefore, you should have your system inspected by an HVAC technician who has the expertise to troubleshoot and repair. Note that preventive maintenance can save a homeowner thousands of dollars in repairs and replacement. Here are some top tips for troubleshooting common central heating problems.
Poor Heat Distribution
A properly functioning central heating system should distribute warm air to all parts of a home. However, when a heater fails to distribute heat throughout a home, then the problem might lie with either leaky ductwork or clogged air filters. First, an HVAC technician will inspect the air filters for signs of dirt and debris that might have accumulated over time. Air filters can be cleaned with pressurised air to allow clean air to pass through ductwork. However, if air filters are damaged, then you need to replace them before checking the ductwork.
Also, when a central heating system's piping is faulty or broken, it can lead to leaks in warm air that restricts sufficient distribution to all zones of a home. Therefore, a technician will check ductwork for leaks and subsequently repair or replace the faulty components for even distribution of heat.
Thermostat Problems
A thermostat is a vital component of a central heating system because it regulates temperature according to the set parameters. Before calling an HVAC expert, ensure that your thermostat is working. Most thermostats are set on "auto" setting as opposed to "on" for automatic regulation of temperature. However, if a thermostat is not working, then the problem might lie with a faulty wiring or a broken unit. Ensure that a thermostat's wiring is plugged in properly before attempting to reset the device to factory settings. In most cases, this solution will get a system up and running. However, try to replace a thermostat if a central heating system malfunctions. For thermostats that are powered by batteries, make sure that the batteries are replaced at least once a year. Overall, a central heating system, whether boiler or furnace, should be serviced at least once a year to ensure safety, economy, and efficient operation.
