Your furnace keeps you warm when the temperatures outside become unbearable. In most cases, a well-cared-for heating unit should give you between one and two decades of excellent service before it starts losing its energy efficiency and falling apart. Therefore, you should watch for the earliest indicators that it is time to replace your unit. Here are the top three signs that the furnace has reached the end of its useful lifespan, and you need to replace it.
When Maintaining the Current System is Too Costly
Consider the possibility that the cost of a new furnace might be cheaper than the combined expenses of repairs you've done this far. Note that installing a new heating system can eliminate the need to hire an HVAC technician for recurring repairs, replace the broken parts, and deal with the cold. So, if you have seen an increase in heating costs, it may be time to replace your aging heater. When analyzing your energy costs, you need to consider the whole picture, not just the price you paid last year. For example, you should assess the age of the system before deciding whether to keep repairing it. If your system is older than its projected lifespan, it will be uneconomical to keep fixing it.
The House is Excessively Dusty
Having dust floating around your house is not ideal, as it causes allergies and infections. A new filter for the furnace may help, but if the furnace itself is old, the problem may persist. So, check for dust, grime, and soot on the surfaces near your registers. Note that it is best to think about an upgrade instead of allowing your furnace to negatively affect your family's health. Further, you will be pleased with the energy efficiency of a new unit, not to mention the new features that will help keep the air in your home free of allergens.
The Unit Makes Unusual Noises
When turned on, a well-maintained furnace in good working order will create a quiet hum, whereas a failing system will likely generate several loud popping and crackles or seems to whir endlessly. In most cases, a system that makes a lot of noise could mean that you need a new furnace or, at the very least, a new motor. Given the higher cost of this replacement part, you should deliberate carefully over your next step and consider a unit replacement for a quiet operation.
