Heat strips for a heat pump typically cost $300-$1,500 installed, with many standard add-ons averaging about $750. Price depends mainly on strip capacity, whether the air handler supports the kit, electrical work, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Heat strip kit | $100 | $300 | $700 | Usually 5-20 kW; brand and capacity affect price |
| Installation labor | $150 | $350 | $700 | Higher for difficult access or wiring changes |
| Electrical upgrades | $0 | $250 | $900 | May include a breaker, wiring, or circuit work |
| Typical installed total | $300 | $750 | $1,500 | Existing compatible air handler assumed |
Installed heat strip prices by air-handler setup
For a compatible air handler with available electrical capacity, a basic heat strip installation is often $300-$800. A larger kit or a job requiring a new circuit can bring the total to $900-$1,500 or more. Replacing an existing failed strip may cost less if the wiring and controls remain usable.
These estimates cover the kit, ordinary installation labor, and routine testing, but not a new air handler or major panel upgrade. Assumptions: U.S. pricing, standard access, compatible equipment, and no extensive code corrections. Confirm the heat strip model and rated capacity match the air handler before comparing quotes.
What the kit, wiring, and installation add to the quote
Quotes differ because some include only the strip assembly, while others include electrical work, control setup, and testing. The itemized ranges below are typical planning estimates, not fixed national rates.
| Quote item | Typical price | Pricing basis | What changes it |
|---|---|---|---|
| Heat strip assembly | $100-$700 | Per kit | Capacity, brand, and compatibility |
| Electrician or HVAC labor | $150-$700 | Per job | Access, wiring, and setup time |
| Breaker and wiring | $100-$600 | Per circuit | Distance to panel and required wire size |
| Controls and testing | $50-$200 | Per job | Thermostat and air-handler configuration |
| Permit or inspection | $0-$250 | Per project | Local rules and scope of electrical work |
Ask whether the estimate includes wiring, breaker work, controls, and testing rather than comparing the kit price alone.
How 5-20 kW capacity changes the strip price
Heat strips are commonly rated from about 5 kW to 20 kW. A 5-7.5 kW kit may suit a smaller system or limited backup-heat need; 10-15 kW kits are common in many homes, while 15-20 kW setups may require more substantial electrical capacity. The right size depends on the equipment manufacturer’s specifications and the home’s heating load, not simply square footage.
Higher capacity can raise the kit price by roughly $100-$400 compared with a smaller compatible assembly. It may also require a larger breaker or additional wiring. For a straightforward replacement, labor may be 1-3 hours at about $75-$150 per hour; circuit changes can extend the visit. Do not upsize a strip without checking the air handler, electrical panel, and manufacturer requirements.
When a new circuit or panel work pushes the estimate higher
A direct replacement can take a few hours when the kit is accessible and existing connections are sound. Adding a circuit or correcting undersized wiring can turn a short HVAC visit into a longer electrical job, with combined labor and materials often adding $200-$900. A crowded or distant electrical panel, attic access, damaged wiring, or required code updates can raise the charge further.
Heat strips draw substantial electricity, so a contractor should verify breaker size, wire gauge, and available panel capacity. A permit may be required for new circuit work depending on the jurisdiction. Request the proposed breaker rating and circuit scope in writing if the quote includes electrical upgrades.
Why regional labor rates change heat strip installation prices
Labor and permit charges vary by location. In lower-cost rural or Midwestern markets, a basic installation may land near the lower end of the range. Large coastal cities and high-cost metro areas can run about 15%-35% above a typical national estimate, particularly when licensed electrical labor is needed. Remote locations may also carry travel or minimum-service charges.
Demand during cold snaps can limit appointment availability, but routine heat strip work is often easier to schedule outside peak heating emergencies. Compare quotes from contractors familiar with the specific heat pump brand, and check whether each quote includes the same electrical scope. Compare equivalent equipment and labor details, not just the total at the bottom.
Three common heat strip quotes for different job scopes
A simple replacement in a compatible air handler might include a $250 kit and 2 hours of labor at $100 per hour, for roughly $450 before taxes or fees. A new 10 kW kit with minor wiring adjustments could total about $700-$1,000, depending on materials and labor.
A 15-20 kW installation requiring a dedicated circuit may reach $1,100-$1,800, especially if the panel is far from the air handler or needs corrections. These examples assume no air-handler replacement and no major service-panel upgrade. The largest quote differences usually come from circuit work and job access, not the strip assembly alone.
Heat strips versus other backup-heat choices
Heat strips are often less expensive to add than replacing a heat pump or air handler, but they use electric resistance heat, which can cost more to operate than the heat pump itself. A repair to an existing strip may be preferable when only a contactor, sequencer, or connection has failed; diagnosis and repair commonly fall around $150-$500, depending on parts and access.
Replacing the full air handler is a much larger project, often several thousand dollars, and is generally not necessary solely to add backup heat if the existing unit supports a compatible kit. Have the contractor distinguish a failed strip component from an air-handler or control-system problem.
How to lower the heat strip installation bill
Before approving a larger kit, ask the contractor to verify the manufacturer-approved size and the home’s backup-heat needs. If the air handler already has adequate wiring and breaker capacity, keeping the project to a compatible strip replacement can avoid a new-circuit charge. Clear the work area and provide model numbers or equipment photos when requesting estimates.
Get two or three itemized quotes that separate the kit, labor, wiring, permit, and diagnostic fee. Avoid paying for a panel upgrade unless testing shows it is needed, but do not skip electrical corrections required for safe operation. Controlling scope and confirming compatibility are the clearest ways to avoid unnecessary cost.
