Dual Fuel Hybrid System Installation in Asheville, NC

A dual fuel hybrid system pairs an electric heat pump with a gas furnace and switches automatically between the two based on outdoor temperature, running the heat pump on mild days and switching to the furnace once temperatures drop low enough that a heat pump alone can’t keep up efficiently. Bullman installs and services dual fuel systems for Asheville area homes weighing the lower operating cost of a heat pump against the cold weather reliability of gas heat, a tradeoff that comes up more often here than in areas without the elevation swings found across Buncombe, Henderson, Haywood, and Transylvania counties.

Installation of Dual Fuel Systems

Installing a dual fuel system means fitting the outdoor heat pump unit and the indoor furnace to share the same ductwork and control wiring, along with a thermostat capable of managing both heat sources. Bullman calculates the balance point, the outdoor temperature where the system switches from heat pump to furnace, based on the specific equipment and the home’s elevation.

How the Switch Between Heat Sources Works

An outdoor temperature sensor feeds a control board that compares the current temperature to the balance point. Above it, the heat pump runs on its own since it costs less to operate per hour. Below it, the system switches to the gas furnace automatically.

Dual Fuel Repair and Maintenance

Because a dual fuel system runs two separate pieces of equipment, a repair call can involve the heat pump, the furnace, or the control logic that decides which one runs. Bullman diagnoses the switching logic separately from the equipment itself, since a system stuck on the wrong heat source points to a control or sensor problem rather than an equipment failure.

Customer Satisfaction

Bullman has installed HVAC equipment across the Asheville area since 1993, including the dual fuel systems that combine two different types of heating equipment under one control setup. Technicians complete ongoing training on both the heat pump and furnace side.

FAQs

How does a dual fuel system decide which heat source to use?

An outdoor temperature sensor feeds a control board that compares the current temperature to a preset balance point. Above that point the heat pump runs on its own, and below it the system switches to the gas furnace, with the exact temperature depending on the specific equipment installed.

How does a dual fuel system save money compared to running a furnace alone?

Running the heat pump instead of the furnace on the more common mild and moderately cold days lowers costs on that portion of the season, since a heat pump costs less to operate per hour above the balance point. Once outdoor temperatures fall below that point, the system switches to the furnace automatically, so the savings come from replacing furnace runtime on the milder days rather than eliminating furnace use altogether.

Can an existing furnace be converted into a dual fuel system by adding a heat pump?

In many cases, yes, as long as the furnace, ductwork, and electrical service can support the added heat pump and control wiring. Bullman evaluates the existing furnace during a consultation to confirm compatibility before recommending a heat pump addition.

If one side of a dual fuel system fails, does the whole system stop heating?

Usually not. If the heat pump fails, the system can typically run on the furnace alone until repaired, and if the furnace fails, the heat pump can often continue heating down to its own performance limit. Bullman confirms which side has failed so the home is not left without any heat during the repair.

Does a dual fuel system need a special thermostat?

Yes. A dual fuel system needs a thermostat capable of managing the switch between the heat pump and the furnace, which is different from the thermostat used with a single heating system. Bullman confirms thermostat compatibility as part of every dual fuel installation.
