Furnace Technology
Advancements in furnace technology have significantly improved energy efficiency and temperature control, providing homeowners with more cost-effective and comfortable heating solutions. Modern furnaces now feature sophisticated components such as variable-speed blowers and modulating gas valves, which allow for precise adjustments to heat output, enhancing overall system performance and longevity.
Single Stage
Operates at a single level of output, running at full capacity until the desired temperature is reached.
Price: Most affordable option upfront
Efficiency: Less efficient due to full capacity operation
Average Lifespan: 15 to 20 years with proper maintenance
Dual Stage
Has two levels of output: high and low. Starts at lower setting and switches to higher if needed.
Price: Moderately priced
Efficiency: Good balance of efficiency, higher energy savings than single stage
Average Lifespan: 20 to 25 years with proper maintenance
Modulating
Provides precise control over temperature, adjusting heat output in small increments.
Price: Most expensive upfront
Efficiency: Most efficient option, significant energy savings
Average Lifespan: 20 to 30 years with proper maintenance
