A Goodman heat strip replacement decision usually starts with one question: is the supplemental electric heat failing, or is the heat pump itself the problem? In Lake Placid, Highlands County, a heat strip that does not respond during a cold spell can leave a home short on heat, and a sudden rise in electric use can be an early sign. This guide explains the symptoms that point toward the heat strip, the safe checks you can make, what a technician would test, and how to weigh repair against replacement. It is general guidance, not a remote diagnosis.
How a heat strip works alongside a Goodman heat pump
A heat pump is the primary heating source in mild weather. When outdoor temperatures drop far enough that the heat pump cannot meet the thermostat call alone, electric heat strips add supplemental or emergency heat. Depending on the installation, the strips sit in the indoor air handler or furnace section. Each element is protected by a limit switch that cuts power if the element overheats, and contactors or relays energize the elements in stages as the thermostat calls for more heat.
A heat strip that runs more than expected can raise the power bill on cold days. A higher bill is a reason to test the system, but it does not prove that a strip has failed. Long heat pump run times, thermostat settings, and airflow problems can produce a similar bill.
Symptoms that point toward the heat strip
These patterns justify a closer look at the electric heat, though each one has more than one possible source:
- No supplemental heat when the thermostat calls for a second stage or emergency heat.
- Only part of the heat working, such as one stage responding while another stays off.
- Strips that run constantly or cycle on and off in rapid succession.
- A breaker that trips when the electric heat energizes.
- A burnt or scorched odor from the air handler or supply vents.
- Higher electric use on cold days without a change in household habits.
A failed element is only one explanation. A stuck contactor, a weak control signal, a limit switch that has tripped because of restricted airflow, or a thermostat staging setting can produce the same comfort results.
Safe checks before you schedule service
These checks are observational and do not require opening equipment.
- Confirm the thermostat settings. Check that the mode is set to heat and that any auxiliary or emergency heat setting matches the guidance in your manual.
- Check the air filter and return grilles. Restricted airflow can make limit switches trip and mimic a heat strip failure.
- Note what runs. Record whether the outdoor unit, the indoor blower, and the electric heat respond when heat is called.
- Record breaker activity. If a breaker trips, note the date and time rather than resetting it repeatedly.
- Keep a symptom log. Write down outdoor temperatures, thermostat settings, and when the problem starts and stops.
Do not open the air handler, the furnace compartment, or electrical panels, and never bypass a limit switch or safety control. Electric heat circuits can remain energized even when the thermostat is off, so leave hands-on testing to a qualified technician.
What a technician tests before recommending replacement
A useful service visit confirms that the heat strip is being called before any part is named. A technician may verify the thermostat and control signals, check the voltage supplied to the heater, measure amperage on each leg, and test element continuity or resistance against the specification for your model. The inspection usually includes limit switches, sequencing relays and contactors, wire connections, and any signs of heat damage at terminals. Airflow across the heater matters as well, and the technician should watch the heat pump run, because the heat pump and the strips share the heating sequence.
The technician should also confirm the exact model and serial number before selecting a replacement part. Matching a strip to a specific Goodman model is a verification step, not an assumption.
Repair or replace: the decisions that matter
Repair and replacement are different decisions. A single failed element, a control part, and a full heat strip assembly each carry different costs and different compatibility questions. Compare these factors:
- Number of failed parts. One failed element with sound controls and wiring is a different case from several failures.
- Age and remaining life. Weigh the repair cost against how long the system is expected to keep running.
- Heat pump condition. If the heat pump has its own faults, a strip-only repair may not solve the comfort problem.
- Part compatibility. The replacement must match the model and serial number on the unit.
- Manufacturer coverage. Confirm whether coverage remains active before work begins. Warranty-aware repair language may apply when manufacturer coverage remains active.
A strip-only replacement generally fits a system where the heat pump runs normally and testing isolates one failed heater part. When testing points to several heating faults, ask for the proposed scope in writing so you can compare a targeted repair with a broader project.
Refrigerant and electrical boundaries
Heat strip replacement is usually an electrical repair rather than a refrigerant repair. If the evaluation expands into refrigerant work, EPA-certified refrigerant handling practices apply to that work. Ask the technician to explain which part of the proposed scope is electrical and which part, if any, involves refrigerant before you approve the work.
Timing, availability, and what to gather before service
Velocity’s repair availability is 24/7, including nights and weekends. Same-day dispatch may be available when a technician is available. Having the following information ready can shorten the call:
- The model and serial number from the Goodman data label on the unit.
- The approximate installation date and any earlier heat strip or heat pump repairs.
- The thermostat type and the mode and settings in use when the problem occurred.
- The symptom log, including breaker activity and outdoor conditions.

Common questions about Goodman heat strip replacement
Does a high electric bill mean the heat strip has failed?
Not by itself. A higher bill on cold days can come from long heat pump run times, thermostat settings, or strips that run more than expected. It is a reason to test the system, not proof of one failed part.
Can I use emergency heat until a technician arrives?
Emergency heat runs only the electric strips, which generally costs more to operate than the heat pump. Treat it as a short-term setting, not a repair. If a breaker trips, the unit smells burnt, or the strips behave unusually, turn the system off at the thermostat and arrange service.
Does a Goodman unit need a Goodman part?
Not automatically. Compatibility depends on the model and serial number, so a technician should verify the exact replacement for your unit before installation.
Could a heat strip repair affect my coverage?
The answer depends on the terms of your coverage and the scope of the work. Ask for a coverage check before approving the repair so the decision is based on the actual terms.
How fast can someone come out?
Velocity’s 24/7 availability, including nights and weekends, is described above. Same-day dispatch may be available when a technician is available, so confirm timing when you call.
Next step: If the electric heat has stopped responding during cold weather, request an evaluation. Ask the technician to show the test results, list the repair and replacement options, and put the recommended scope in writing before you approve any work.
