Furnaces play a valuable role in today’s society, allowing families to easily heat their homes even during the cold winter months. Unfortunately, despite incredible improvements in efficiency in recent decades, furnaces still aren’t designed to last more than 10 to 15 years. With careful maintenance, though, that lifespan can be extended.
Most experts suggest that homeowners have their furnaces serviced at least once a year, ideally before the winter season begins, and provide routine maintenance themselves throughout the season. This helps to ensure that any problems are discovered early on before they can wreak more havoc. Sadly not all homeowners take this valuable advice, but everyone can at least look out for these warning signs that furnace repair is already needed.
Most furnaces make at least a little bit of noise in the course of normal operation. However, bangs, pops, and squeals are not normal noises. If a residential unit is making these or other disconcerting sounds, it’s time to call in a pro to evaluate the problem and offer professional advice.
Furnaces are designed to turn on when the thermostat indicates that the temperature has dropped below the desired range, then turn back off when they’ve produced enough heat. If instead, it is turning itself on and off in rapid succession there could be a problem with the thermostat or the ignition. Both of these issues can be addressed by a repair technician.
Unexplained Increase in Heating Cost
It’s not always obvious when something is going wrong. Plenty of furnaces begin their slow decline without so much as a bang, but that doesn’t mean they should simply be ignored. Homeowners should pay attention to their monthly heating bills and keep an eye out for unexplained increases, as they may indicate that the furnace is becoming less efficient due to internal mechanical problems.
It’s Just Old
While it’s true that every homeowner should probably have his or her furnace checked by a professional on an annual basis, those that have furnaces more than a decade old need to take this advice even more seriously. Providing an aging furnace with needed maintenance and repairs can often extend its lifespan, sometimes even by a matter of years.
