Through modern engineering, the system can run anywhere from 40 to 100% capacity
A properly maintained furnace normally lasts fifteen to twenty years. Being diligent about annual maintenance and repairs can extend its life even longer. Eventually, however, the heating system will fail. Waiting for the furnace to quit entirely before replacing it can be a mistake. Heaters normally malfunction when the equipment is working the hardest, which is typically during the coldest weather. Scrambling to get a furnace installed as quickly as possible leaves no room for shopping around. There’s no time to look into features, research contractors, be sure of sizing or choose the ideal furnace for the specific home. You’re forced to accept whatever make, model and size is available. Leading up to the end of service life, most furnaces aren’t operating at their best. You might notice inconsistent temperatures from one room to another. Turning up the thermostat might not make much of a difference on especially cold nights. Unfortunately, as comfort diminishes so does efficiency. The furnace will start to run for longer cycles, fail to supply enough heated air and yet cost more to operate. There can be numerous minor repairs that are aggravating, and the cost swiftly adds up. Air quality also suffers, and there can even be safety risks. Even if the furnace is only ten years old, there have certainly been improvements in heating technology. Today’s models achieve AFUE ratings of 98%. They include adaptable-speed technology that allows the heating system to match output to the demands of the home. Through modern engineering, the system can run anywhere from 40 to 100% capacity. It can adjust in tiny one percent increments. The extended run times at lower speeds not only reduces costs and carbon footprint but lessens operational noise, issues with humidity and concerns with temperature fluctuations.
