| Climate Suitability | Best for southern regions/mild needs or as backup | Best in moderate climates, less efficient below 30°F |
| Operating Cost | High, due to electricity use | Lower, due to efficient energy transfer |
| Upfront Cost | Lower equipment and setup | Higher |
| Maintenance | Minimal | Regular checks and servicing required |
What Are Heat Strips?
Electric heat strips are components of HVAC systems that use electric resistance to generate heat. When turned on, electricity flows through coiled metal wires or strips, producing warmth that is blown into the living space. They are simple, reliable, and commonly used as an auxiliary or backup source of heat.
This method is especially common in air handlers for central heating and in packaged HVAC units. Heat strips offer straightforward on-demand heating but come with notable operational costs due to the way they convert electricity to heat.
How Do Heat Pumps Work?
A heat pump is a device that moves heat from one place to another with the help of refrigerant. In winter, the system absorbs outdoor heat—even from cold air—and brings it indoors. In summer, the process reverses to act as an air conditioner by removing heat from indoors.
Modern heat pumps are celebrated for their energy efficiency. One unit of electricity can deliver two to four units of heat energy, thanks to the thermodynamic process of heat transfer rather than direct heat generation. This efficiency produces significant savings in energy and cost, especially in moderate climates.
Energy Efficiency: Which Option Wins?
The energy efficiency difference between heat strips and heat pumps is significant. Heat strips have an efficiency rating (COP) of 1.0—they transform all the electricity used into heat, and no more. On the other hand, heat pumps leverage heat transfer: for each unit of electricity, they deliver two to four units of heat, making them as much as 400% efficient compared to the 100% efficiency limit of heat strips.
This efficiency gives heat pumps a clear edge for ongoing operating costs throughout the heating season.
Operating Costs And Utility Bills
Heat strip systems generally cost much more to run than heat pumps. If your home is heated primarily with electric resistance strips, you can expect your winter power bill to spike, particularly in regions with extended cold periods. By contrast, houses with heat pump systems benefit from reduced energy consumption and less dramatic energy bills over time.
- Average heat strip heating costs: $0.20 – $0.40 per hour per kW
- Average heat pump heating costs: $0.07 – $0.15 per hour per kW equivalent
This cost gap grows wider as the square footage and number of hours required for heating increase, making heat pumps a preferred solution for cost-conscious homeowners.

Climate Suitability And Regional Recommendations
The suitability of heat strips versus heat pumps is closely tied to your climate zone. Heat pumps perform best in regions with mild to moderate winters—such as most of the Southeast and West Coast. Heat strips become necessary either as backups for very cold snaps or as the main source in southern states that rarely experience freezing temperatures.
In Northern or cold-climate areas where temperatures regularly drop below 30°F, standard heat pumps lose efficiency. In these cases, dual-fuel or backup heating systems that engage heat strips during the coldest days provide reliable comfort.
Installation And Upfront Costs
Heat strips are usually cheaper to install than heat pumps. The typical cost of adding electric heat strips to an existing air handler ranges from $200 to $800. In contrast, a new central heat pump system runs $4,000 to $8,000 or more, depending on home size and technology grade.
- Heat strip installation: $200 – $800+
- Heat pump installation: $4,000 – $8,000+ (equipment + labor)
This difference means heat strips might be suitable for smaller budgets or supplemental heat needs, while heat pumps are a larger investment offering long-term energy savings.
Maintenance And Longevity
Heat strips require minimal ongoing maintenance. They have few moving parts; most issues involve electrical connections or simple component failure. Once installed, they usually operate without much attention, aside from seasonal checks.
Heat pumps, however, require more regular maintenance—cleaning coils, checking refrigerant levels, and servicing moving parts. With routine care, heat pumps can last 10–15 years before major repair or replacement is necessary.
Performance In Extreme Cold
One of the most notable limitations of heat pumps is reduced efficiency at very low temperatures. As outdoor air cools, less ambient heat is available, and the system may struggle to meet indoor comfort needs. When this happens, integrated electric heat strips typically turn on automatically as a supplemental heat source, which increases energy use and costs.
In regions where winter lows dip below 20°F for days or weeks, many HVAC contractors recommend dual-fuel heat pump systems that combine an electric or gas furnace for backup, delivering both efficiency and reliability.
Environmental Impact
Electric heat strips generate heat using electricity, which in the U.S. is still partly derived from fossil fuels. Thus, using heat strips as a primary heat source has a larger carbon footprint. Heat pumps, because of their much higher efficiency, are considered more environmentally friendly, particularly in states with a cleaner electric grid or access to renewable energy sources.

Comfort, Noise, And Air Quality
Heat strips deliver instant warm air, but running them continuously can dry out indoor air, potentially causing discomfort or aggravating allergies. Heat pumps circulate air more gently and maintain more consistent humidity, which benefits indoor comfort and air quality.
Both systems are typically quieter than traditional furnaces, but some homeowners notice a faint clicking when heat strips engage or compressor noise from the heat pump’s outdoor unit.
Integration With Existing Home HVAC Systems
Many modern air handlers support both heat strips and heat pumps, allowing for seamless hybrid operation. Upgrading to a heat pump often preserves ductwork and reduces the need for major home renovations. Adding heat strips can be accomplished with minimal electrical work if your equipment is compatible.
Consulting with a licensed HVAC professional ensures your planned system will meet both technical requirements and comfort needs.
Smart Controls And Energy Management
Newer HVAC controls allow smart switching between heat pump and heat strip modes based on outdoor conditions, electricity rates, or time of day. Smart thermostats optimize energy use and improve comfort by minimizing auxiliary heat strip use and leveraging the heat pump whenever possible.
Some systems offer real-time reporting, letting homeowners track electric use and adjust habits to save even more on utility bills.
