Overview
A heat pump moves heat instead of making it. In winter it pulls warmth from the outdoor air, even when it feels cold, and delivers it inside; in summer it runs in reverse to cool the house. Because it moves more heat than the electricity it uses, a heat pump can heat very efficiently in mild to moderate weather.
A dual-fuel system, sometimes called a hybrid, pairs a heat pump with a gas or propane furnace. A control system chooses the better source based on the outdoor temperature. On mild winter days the heat pump does the work, and when the temperature falls low enough that a furnace is more effective, the furnace takes over.
Central Kentucky is well suited to this approach. Winters here are cold, but the region has long stretches of mild weather in fall and spring and many days in the 30s and 40s, when a heat pump shines. The coldest nights, when the outdoor unit works hardest, are exactly when a furnace backup is valuable.
This can be an especially good fit for homes outside natural gas service, where the alternative is propane or resistance electric heat, and for homeowners who want one system for both heating and cooling. A contractor can walk through all-electric heat pump, dual-fuel, and furnace-only options and how each would run through a Kentucky winter.
Replacement means more than swapping the furnace. A heat pump system includes an outdoor unit, an indoor coil or air handler, refrigerant lines, and controls, and in a dual-fuel setup it also includes the furnace. The ductwork needs to move enough air for the heat pump, and the electrical supply may need attention.
Sizing and installation quality matter a great deal. A heat pump that is too small will lean on backup heat too often, and one that is too large will cycle inefficiently. Lines, charge, and controls must be set correctly, and the contractor should commission the system carefully.
It is worth thinking about operating costs across a whole year, not just winter. Because the same equipment cools in summer, homeowners replacing an old furnace and an old air conditioner together sometimes find a single, well-matched system makes the most sense. Your contractor can help you compare the options.
The contractor we match you with will explain how the system will operate in your home and put the equipment, controls, electrical work, and warranty in a written estimate, so you can compare a heat pump or dual-fuel setup against a new furnace on the same terms.
Signs you need heat pump & dual-fuel systems
Any one of these is worth an in-home evaluation from the contractor we match you with.
- You are replacing both an aging furnace and an aging air conditioner
- Your home has no natural gas and you use propane or electric resistance heat
- You want lower fuel use on mild winter days without giving up backup heat
- You would like one system that heats and cools
- Your current heating and cooling equipment is mismatched or inefficient
How heat pump & dual-fuel systems works
Every job starts with an in-home evaluation from the contractor we match you with.
- 1Evaluate the home
The contractor measures the house, checks the ducts and electrical service, and asks how you heat and cool today.
- 2Compare system types
All-electric heat pump, dual-fuel, and furnace-only options are laid out with how each would perform in winter.
- 3Size the equipment
A load calculation sizes the heat pump and any backup furnace so neither is over- or undersized.
- 4Install outdoor and indoor units
The outdoor unit, indoor coil or air handler, refrigerant lines, controls, and any furnace are installed and connected.
- 5Commission the system
The contractor sets refrigerant charge and controls, tests both heating sources, and explains how the system switches between them.
Why homeowners choose it
- Efficient in mild weather
- A heat pump can deliver more heat than the electricity it uses on many winter days.
- Backup for hard freezes
- In a dual-fuel setup, the furnace handles the coldest nights when a heat pump works hardest.
- Heating and cooling in one
- The same outdoor unit provides air conditioning in summer, simplifying your equipment.
- Flexible fuel choices
- Dual-fuel systems let you use the fuel that makes sense as prices and weather change.
- Steadier comfort
- Variable-speed heat pumps run longer at lower output for more even temperatures.
Typical scenarios
Illustrative examples of the situations homeowners bring to us. They are not specific customer jobs.
Consider a Versailles farmhouse heated with propane. The contractor installs a heat pump with a propane furnace as backup, so the heat pump handles the mild days and propane only runs when the weather demands it.
Imagine a Tates Creek home with a tired furnace and an aging air conditioner. The contractor proposes a matched heat pump system with a compact gas furnace, and puts both the all-in-one option and a like-for-like replacement in writing.
What affects your estimate
We cannot quote a price without seeing the home, but this is what typically goes into a contractor's written estimate.
- 1The size and efficiency of the heat pump and any backup furnace
- 2The indoor coil or air handler, refrigerant lines, and control setup
- 3Electrical service and wiring for the outdoor unit and controls
- 4The condition of the ductwork and any airflow modifications
- 5Thermostat compatibility, permit, and the warranty on each component
Keeping it running
A few habits that help new equipment last.
- Keep the outdoor unit clear of snow, ice, leaves, and debris
- Change indoor filters on schedule so airflow stays strong
- Schedule annual service for both the heat pump and the furnace
- Learn how the thermostat chooses between heat sources
- Report ice buildup, odd noises, or short cycling promptly
Lexington weather and your furnace
Lexington's winter has plenty of mild spells and the occasional deep freeze. A heat pump handles the mild spells efficiently, while a furnace backup takes over when the outside temperature falls far enough that heat pump output drops. Together they are matched to the region's swings.
Freezing rain and snow can cover an outdoor unit, so it helps to keep the area around it clear and to know what defrost operation looks like. Heat pumps periodically defrost themselves in cold, damp weather, which can produce steam or a brief pause that is normal.
Myths vs. facts
Heat pumps do not work in cold climates.
Modern heat pumps work in cold weather, though output drops as temperatures fall. Dual-fuel systems address the coldest days with a furnace.
A heat pump replaces the need to think about backup heat.
Most cold-climate setups include backup, either electric elements or a furnace, and your contractor should explain what yours will use.
A dual-fuel system is too complicated to be worth it.
Modern controls handle the switching automatically. The benefit depends on your fuel prices and your home.
Heat pumps are only for cooling.
They heat as well as cool. Many homes use them as the primary heating source in mild weather.
Frequently asked questions
What Lexington homeowners ask about heat pump & dual-fuel systems.
It uses refrigerant to pull heat from the outdoor air and move it inside. Even cold air contains heat that the system can capture.
