Plan for this house

Dual Fuel

Furnace home keeping fossil backup: dual fuel gives heat-pump savings with furnace security on the coldest days. Set the balance point.

Lead with Dual fuel (heat pump + existing furnace): Heat-pump savings for most of the year, furnace security on the coldest nights, nothing removed. Present the 2 brand-neutral fallback option(s) only if the homeowner declines the heat pump, and always price the lit option beside any fallback.

Cooling load38,000 BTU/hr

  • Supply the electric rate, fuel price, and HP COP to compute the economic switchover. Without them the switchover is set on capacity (thermal) alone.
  • Heat pump meets the load to the tested floor. No capacity switchover needed; the furnace is redundancy or pure economic backup. Set the switchover on economics if rates are supplied.
  • Run is 0.4 ft past the 24.6 ft factory pre-charge: add refrigerant per the model charge rate (see refrigerantChargeEstimate) and weigh it in.
  • Dual fuel requires a dual-fuel-capable control with an outdoor sensor to stage heat-pump-to-furnace on outdoor temperature. Do not run the furnace and heat pump together.
  • A C (common) wire is required for modern wifi / smart controls. Verify a true common is landed, not a jumper.
  • Maintain condenser clearances: ~12 in sides, 24 in service side, 60 in overhead, 6 in back. Confirm exact values against the model install manual.
  • Confirm the condensate path: gravity drain if a downhill route exists, otherwise a condensate pump with a float safety switch.
  • Snow region: mount the condenser on a stand/riser above the expected snow line, keep the base-pan drain clear, and protect from roof-shed ice. Wall brackets help in heavy drift.

Coverage on this house

Parts term and labor term are what this shop writes on the contract. Flex does not assume a manufacturer labor term is present on this house.

Available is not the same as present. Register the system if the program requires it. Do not invent a second service plan. Do not quote a dead federal credit.

We will wait until next year.

Programs change. Equipment lead times change. The number on this page is today. If they wait, re-run the job before you honor it. Offer to hold the file on Command so the next visit starts from a live quote, not a napkin.

Do not lock a price you cannot hold. Do not invent a deadline that is not on the program page.
