Our Work in Maple Valley

Bosch heat pump added to a Trane gas furnace, 3 ton

Outside, the Bosch unit stands on a pad over fresh gravel against the wood siding, with the line set run to the house under a white cover. In the garage, the refrigerant lines go to the coil above the Trane furnace.

  • The Bosch heat pump on its pad.
  • In the garage: the Trane furnace, now paired with the heat pump.
  • Up close, on fresh gravel.
  • Lines and power connected at the corner.
  • The finished install along the wall.
  • The same garage, seen from the side.
  • Measuring along the wall during the install.

A heat pump on top of a gas furnace

This Maple Valley home already heated with a Trane gas furnace in the garage. The owners wanted to pay less for gas, so instead of replacing anything we added a 3 ton (36,000 BTU) Bosch heat pump to the system.

The furnace stayed where it was. The heat pump outside and the coil above the furnace now share the same ductwork, and together they make a dual fuel system: two sources of heat, one set of ducts.

The install took two working days.

Who decides when the furnace runs

In a dual fuel system the thermostat chooses. It switches between the heat pump and the furnace by the outdoor temperature: the heat pump heats the house in milder weather, and the furnace takes over when it gets cold.

You set the temperature once, as with any thermostat, and the switch between the two happens on its own. In summer the same heat pump cools the house.

Common Questions

FAQ: HVAC in Maple Valley

When does the heat pump run, and when does the furnace?

The thermostat switches between them by the outdoor temperature. In milder weather the heat pump heats the house; when it gets cold, the furnace takes over.

Can I add a heat pump to my existing gas furnace?

Yes, if the furnace is in good working order. On this Maple Valley job a Bosch heat pump was added to a Trane furnace that was already there, and the furnace kept its place in the garage.

Why add a heat pump instead of keeping only the furnace?

To pay less for gas, which was the reason on this job: the heat pump covers the milder days, so the furnace runs less. The heat pump also cools the house in summer.

How long does it take to add a heat pump to a furnace?

This one took two working days, with the furnace staying in place the whole time.
