A well-maintained furnace can last fifteen to twenty years.
However, it can prove cost-effective to replace an older furnace that continues to operate.
Models that are more than ten years old gradually diminish in efficiency, heating capacity and reliability. Wear and tear on the system can result in frequent minor repairs that quickly add up in expense. The unit might need to run longer to achieve the thermostat setting, using more energy and leading to higher utility bills. Modern furnaces achieve much higher efficiency levels, with top-of-the-line models offering 98% AFUE ratings. Systems featuring adaptable-speed technology automatically adjust output to supply only the exact amount of heat necessary at any given time. Rather than blasting at max capacity and shutting down once the desired temperature is reached, the system maintains ideal comfort through lower speeds and longer run times. These systems are capable of adjusting in tiny one percent increments. The result is less strain on components, less cost of operation and lower sound levels. There are fewer problems with insufficient humidity and greater opportunity for air filtration. Plus, the more consistent temperature is more comfortable. Today’s furnaces also accommodate wifi connectivity and zone control. Rather than heat the entire house to a uniform temperature, wireless thermostats installed into each room cater to occupancy, preferences and requirements. The furnace can be adjusted by way of a smartphone at any time from virtually any location. The greater energy savings and manufacturer’s warranty coverage help to quickly recover the initial investment. For homeowners with an older furnace, it’s better to be proactive rather than wait for the current furnace to fail. No one wants to be stranded without heat during the middle of the winter. There is always the risk of pipes freezing and bursting. Not only is it more convenient to schedule heating system replacement over the summer, there is the opportunity to shop around and find the ideal system for the demands of the household.
