FAQ

Frequent repairs, uneven heating, increasing energy use, unusual noises and difficulty keeping the home comfortable can indicate that furnace replacement is worth considering. A technician can compare repair and replacement options based on the system’s condition.

Furnace sizing depends on more than square footage. Home layout, insulation, windows, ductwork and heating load should all be considered before choosing equipment.

AFUE measures how efficiently a furnace converts fuel into heat. A higher AFUE rating indicates that a greater percentage of the fuel is converted into usable heat for the home. Many furnaces currently listed by Convertible Air offer efficiencies around 96% to 97% AFUE.

The best heating system depends on the home’s existing equipment, ductwork, size, insulation and comfort goals. Common options include high efficiency furnaces, boilers, combi boilers, hydronic systems and cold climate heat pumps.

A furnace distributes heated air through ductwork, while a boiler typically uses heated water with radiators, baseboards or hydronic systems. The right choice depends largely on the home’s existing heating infrastructure.
