Dual-Fuel HVAC Systems
The smartest heating system available — a dual-fuel system pairs a heat pump with a gas furnace to automatically choose the most efficient heat source at every outdoor temperature in Pflugerville, TX.
How Dual-Fuel Systems Work
A dual-fuel system, also called a hybrid heat system, uses a heat pump as the primary heating source and a gas furnace as the backup. A smart controller monitors outdoor temperatures and automatically switches between the two — always choosing the most efficient and economical option.
Smart Switchover
When outdoor temperatures drop below the heat pump's optimal efficiency point, the system automatically switches to the gas furnace — maintaining comfort without wasting energy.
→Maximum Efficiency
A heat pump is more efficient than gas above ~35°F; gas is more efficient below. Dual-fuel uses the right fuel source at the right time — delivering the lowest possible heating costs.
→Reliable in All Temperatures
Unlike a heat pump alone, a dual-fuel system has the gas furnace as a backup — ensuring full heating capacity even in the coldest weather.
→System Installation
We install complete dual-fuel systems — including heat pump, gas furnace, smart controls, and all connections.

→Dual-Fuel System FAQs
What temperature does the system switch over?
The switchover temperature, called the "balance point," is typically set between 30–40°F. Below this temperature, running the gas furnace costs less than the heat pump. We configure this precisely for your home and local energy rates.
How much can I save?
Most homeowners with dual-fuel systems save 30–50% on annual heating costs compared to gas-only or electric-only systems. The exact savings depend on your home's size, insulation, and local energy rates.
Is it complicated to maintain?
Not at all. We provide annual maintenance that covers both the heat pump and furnace sides of the system in a single visit — it's actually simpler than maintaining two separate systems.
Can I add a heat pump to my existing furnace?
In most cases, yes. If your existing gas furnace and ductwork are in good condition and compatible, we can add a heat pump to create a dual-fuel system without replacing the furnace. We'll assess your system during a free consultation.
