A high-efficiency gas furnace uses a two-stage heat exchange process to capture nearly all the warmth from burning fuel. By condensing vapor from exhaust gases, it achieves up to 99% efficiency—an ideal solution for Toronto, Ohio homes facing long winters and steep utility costs.
Toronto’s riverfront neighborhoods, older frame houses, and newer builds along Franklin and Ridge avenues all benefit from efficient heating. Many homes near Toronto Junior/Senior High School or the river valley still rely on older 70–80% AFUE furnaces that vent hot air directly outside. Modern condensing models reuse that heat, providing steady warmth and cleaner indoor air throughout the Upper Ohio Valley season.
Air and natural gas ignite inside a sealed combustion chamber, heating a primary heat exchanger that transfers energy to the home’s air supply. Instead of losing the leftover heat, the exhaust moves through a secondary heat exchanger, where it cools and condenses into water. This process releases additional heat that older systems waste. The cooled exhaust—now just warm air—exits through PVC pipes rather than a chimney, making installation easy in compact Toronto basements.
A variable-speed blower circulates warm air quietly across two-story homes on Clark Street or the downtown flats. The induced draft motor manages combustion airflow, maintaining safety and efficiency. Electronic ignition removes the need for a pilot flame, reducing gas consumption, while sealed PVC venting brings in outdoor air for clean, balanced combustion. Together, these features make today’s furnaces quieter, safer, and far more fuel-efficient.
Toronto’s cold river air and older home layouts can challenge heating consistency. Condensing furnaces maintain low-speed airflow for even temperatures, reducing drafts and preventing rapid cycling. Because their exhaust is cooler, they’re also better suited to damp basements common along River Avenue—less corrosion, more comfort, and steady humidity control through the winter.
That’s condensate—water created as exhaust vapor cools. It’s safely drained and part of normal operation.
No. High-efficiency furnaces require PVC venting because the exhaust is too cool for metal.
Just yearly service. Cleaning the condensate drain and testing the sensors helps maintain top efficiency in Ohio Valley conditions.
