Upgrade Your Home's Heating Efficiency

Today's high-efficiency gas furnaces can significantly improve efficiency, comfort, and performance compared with older heating systems. Sun Services offers gas furnaces ranging from 80% AFUE models to high-efficiency systems rated up to 98%+ AFUE.

AFUE, or Annual Fuel Utilization Efficiency, measures how efficiently a furnace converts fuel into usable heat. A higher AFUE rating means more of the fuel your furnace uses is converted into heat for your home.

Depending on your equipment, home, and heating needs, upgrading to a higher-efficiency furnace may reduce energy use while providing more consistent indoor comfort.

Gas Furnace FAQs

  • Signs that it may be time to consider replacing your furnace include frequent repairs, increasing heating costs, uneven temperatures, unusual noises, or difficulty keeping your home comfortable. The age and overall condition of your furnace should also be considered. Sun Services can evaluate your existing system and help you understand your repair and replacement options.

  • AFUE stands for Annual Fuel Utilization Efficiency and measures how efficiently a furnace converts fuel into usable heat over a heating season. A higher AFUE rating means a greater percentage of the fuel used by the furnace is converted into heat for your home.

  • A single-stage furnace operates at one heating output, while a two-stage furnace can operate at a lower or higher heating level depending on your home's needs. Variable-speed technology adjusts blower airflow to help provide more consistent temperatures, quieter operation, improved comfort, and efficient system performance.

  • The correct furnace size depends on more than your home's square footage. Insulation, windows, construction, ductwork, air leakage, and your home's heating requirements can all affect proper equipment sizing. Sun Services can evaluate your home to help determine the appropriate furnace size for reliable and efficient heating.
