Dual Fuel Heat Pump and Gas Furnace Systems in Kitsap County
Picture a heating system that picks the most economical way to warm your home, hour by hour. That’s the idea behind dual fuel. An electric heat pump handles heating and cooling while the weather is mild. When the outdoor temperature falls below a set point, called the changeover or balance point, a gas furnace takes over the heating.
Around Bremerton, Silverdale, and Poulsbo, our winters stay damp and moderate, so the heat pump can carry most of the year. The furnace waits in reserve for the handful of nights that drop to freezing or below.
Delta T Comfort installs, services, and repairs dual fuel systems across the county. This setup isn’t right for every household. It requires natural gas or propane at your home, and for some families a heat pump, or a furnace alone, is the smarter purchase. Before we recommend anything, we look at your current equipment.

Dual Fuel Installation and Replacement
Dual fuel can mean the best of both - efficent heating through most of the winter and a back up system that provides warm heat when the heat pump can't. This helps cut down on fuel costs, especially when you have more than one appliance using natural gas or propane through the winter.
Situations where dual fuel often makes sense:
A gas furnace paired with an aging air conditioner
A heat pump can replace the AC and share the heating load, while your existing furnace stays on as the cold-weather partner, as long as it’s in good condition.
A heat pump that falls behind in the cold
Heat pumps put out less heat as temperatures drop, and many systems fill the gap with electric resistance strips, which are expensive to run. Giving those hours to a gas furnace can cost less.
Winter bills that keep rising
When the system can choose between electricity and gas based on the outdoor temperature, you have more control over what you pay.
Both major components near the end of their lives
Replacing the furnace and outdoor unit together lets us match the equipment, wiring, and controls so they work together correctly from day one.
Getting dual fuel right depends on details most homeowners never see. We run a load calculation to size the equipment, confirm that the furnace, indoor coil, outdoor unit, and thermostat are built to work together. If your current furnace is a good candidate, we’ll say so and leave it in place. If it isn’t, you’ll hear that too.
Financing is available with approved credit, and we can walk you through utility rebates that may apply to a new heat pump.
We size every system before we provide the estimate, so call (360) 821-3114 to schedule an in-home estimate.
Dual Fuel Repairs
With two heat sources and a control that chooses between them, a dual fuel system can fail in ways that look confusing. The house is chilly, but is the heat pump struggling, is the furnace refusing to start, or is the thermostat sending the wrong signal? We test each piece and the connection between them, so the repair matches the real problem.
Warning signs worth a call:
-
Air from the vents that feels barely warm
-
The furnace firing up on a mild afternoon, or the heat pump still running through a hard freeze
-
A gas or power bill that jumped without any change in your habits
-
Frost or ice on the outdoor unit that never clears
-
A furnace that clicks or tries to light but won’t ignite
-
A thermostat that freezes, goes blank, or shows an error
Behind those symptoms, we often find an outdoor temperature sensor reading wrong, a defrost control that isn’t cycling, a thermostat programmed with the wrong settings, a worn igniter or flame sensor, or a failed control board. Because gas and electric components share one system, we also check wiring and safety switches before replacing any parts.
You’ll get a clear explanation of what failed, along with a price, before work begins. Our goal is to fix what’s broken, not to sell what isn’t.

Dual Fuel Maintenance
Two systems under one roof means two sets of parts that wear, plus a control scheme that has to keep working. A dual fuel tune-up looks at all of it.
What we inspect, measure and check:
-
Outdoor coil condition and refrigerant pressures
-
Defrost cycle and reversing valve operation
-
Furnace burners, ignition, flame sensor, and heat exchanger
-
Venting
-
Thermostat programming
-
Electrical connections, drain line, and air filter
We record the actual measurements instead of a color-coded score, so over the years you can see which parts are aging and plan ahead.
Book a fall visit to test the furnace before heating season, plus a shorter cooling check in the spring. We can schedule visits more than a year ahead so they never slip. The payoff is steadier comfort, fewer midwinter no-heat calls, and lower fuel use because each heat source runs when it should.
