Delaware OH basement requires horizontal Tempstar Furnace


Delaware, OH 43015


An 1880s home in Delaware County had a 35-year-old low-boy furnace on the floor in the short basement.  It had standing-pilot ignition, was rated 63% fuel efficiency, and had no room for an air conditioning coil.  The blower was belt-driven, and the air filter did not have easy access.

Project Solution Benefits & Details

Scott Haring measured the old furnace, and mapped the supply air and return air ducts.  Field Supervisor Vic finalized the design for new insulated sheet metal ducts allowing a 96% efficiency Tempstar F9MVE furnace to be mounted horizontally.

  • Planning and design – Comfort Advisor Scott Haring measured the old furnace and mapped the supply and return air ducts.
  • Execution – Field Supervisor Vic finalized the design for the new insulated sheet metal ducts we fabricated in our sheet metal shop.
  • Most popular furnace – The Tempstar F9MVE gas furnace was selected for best fit and best value.
  • Breathes easy – Two-pipe venting with PVC pipe draws combustion air from outdoors and exhausts through the basement wall.
  • Thrifty gas consumption – The new furnace is two generations newer and rated 96% efficient.
  • Thrifty electric consumption – The high-efficiency variable-speed ECM blower motor delivers proper airflow.
  • Indoor Air Quality –  A high-capture media air cleaner was installed that uses a common disposable 20 x 25 x 4” thick air filter.
  • Future expansion –  The house did not have central air conditioning; we incorporated a provision for an evaporator coil in the new ductwork.
  • High and dry –  The entire assembly was perched on risers to keep it off the floor in case of ground water intrusion.
  • Remote drain – The condensate collects into a pump and is sent to a sanitary drain in the adjacent room.

“This grand old home deserved a heating upgrade, and Custom Air made the most of the opportunity with a new high efficiency furnace and valuable features.”Scott Haring


It was a big job, but our talented installers made sure it was done neatly.  It looks and works great and will save energy.  A future project may include a Mitsubishi Zoned Comfort System to serve the second floor, to manage the summertime cooling requirements.
