High Electric Bills? Your Heat Strips Might Be the Culprit
If your electric bill spiked this winter and you have an Amana heat pump in Seffner, the prime suspect is often the last component anyone thinks about: the heat strips. Also called auxiliary or emergency heat, these electric resistance elements are the most expensive way your system can make heat — several times the cost of normal heat-pump operation. When they run more than they should, or get stuck on entirely, your bill tells the story before anything else does. Here is how to read that story, what causes it, and what a proper heat strip replacement involves.
How Heat Strips Drive Up Your Bill
A heat pump heats efficiently by moving existing heat from the outdoor air into your home. Heat strips do the opposite: they make heat from raw electricity, like a giant toaster inside your air handler. They exist for good reasons — as backup during defrost cycles, as a boost on the coldest nights, and as emergency heat if the outdoor unit fails.
The problem is cost. Electric resistance heating consumes far more electricity per unit of warmth than the heat pump. Occasional strip use barely registers on a bill. But strips running for hours a day — or worse, stuck on around the clock — can double or triple the heating portion of your electric bill in a single month. When a Seffner homeowner sees a sudden, unexplained bill spike in heating season, strips running amok are the first thing a technician investigates.
Why Strips Run Too Much: The Three Causes
Excessive strip use almost always traces to one of three faults:
- A stuck sequencer or contactor. Heat strips are switched on and off by sequencers and contactors — electrical relays that stage the elements. When a sequencer welds shut or a contactor sticks, the strips stay energized regardless of what the thermostat wants. This is the classic “bill doubled overnight” failure, and it is purely electrical.
- A struggling heat pump forcing backup. If the outdoor unit is underperforming — low refrigerant charge, a dirty coil, a failing component — it cannot meet the heating load, so the system leans on the strips to make up the difference. Here the strips are a symptom, and the real repair is in the outdoor unit.
- Thermostat or control misconfiguration. Wrong settings, a miswired new thermostat, or a failed outdoor sensor can call for auxiliary heat far more often than conditions warrant. The equipment is fine; the instructions are wrong.
Telling these apart is the whole job of the diagnosis — because replacing strips when the real fault is a struggling heat pump fixes nothing, and vice versa.
How to Tell It Is the Strips
A few observations point squarely at strip trouble. The most telling: your outdoor unit is quiet or barely running, yet the house stays warm and the bill is enormous — that means the strips are doing all the work. Another: you hear repeated clicking from the air handler as elements stage on and off far more than the weather justifies. And the bill pattern itself is evidence: a sharp spike confined to heating months, with no change in your household habits, is the fingerprint of resistance heat running wild.
One caution: do not open the air handler to look at the elements yourself. Heat strips operate at high amperage and stay dangerously hot after shutdown. Observation from the thermostat and the bill is the homeowner’s job; everything inside the cabinet is the technician’s.
The Replacement: What Actually Gets Done
A proper heat strip service starts with electrical diagnosis, not parts-swapping. The technician measures amp draw on each element to find which are energized when they should not be, tests the sequencers and contactors for sticking or failure, inspects the elements themselves for breaks or hot spots, and verifies the thermostat and control wiring are calling for heat correctly.
What gets replaced depends on the finding: failed sequencers, a welded contactor, or degraded elements — including Nichrome element upgrades where the design calls for them. Genuine Amana-matched components matter here because strip kits must match the air handler’s electrical ratings and staging design; the wrong kit is a safety hazard, not just a performance issue. The work is performed with proper lockout procedures by qualified technicians, and warranty-safe service keeps your manufacturer’s coverage intact.
Repair or Replace — and Preventing the Next Spike
Strip-component replacement makes sense when the elements, sequencer, or contactor is the confirmed fault and the rest of the system tests healthy. It is targeted, same-day work. But if the diagnosis shows the strips were only compensating for a failing outdoor unit, the honest recommendation addresses the heat pump itself — because new strips on a dying system just produce expensive heat for a little while longer.
Prevention is straightforward: scheduled maintenance that cleans the outdoor coil, verifies refrigerant charge, tightens electrical connections, and tests strip staging before heating season. A system whose heat pump carries its full load barely touches the strips — and the bill shows it.

Frequently Asked Questions
How long does a heat strip replacement take?
Most strip-component replacements — sequencers, contactors, or elements — are completed within a standard service visit once diagnosed. The electrical diagnosis itself typically takes under an hour.
Is it safe to keep running the system with faulty strips?
A stuck sequencer keeping strips energized is an electrical fault that should be addressed promptly — it wastes significant electricity and stresses the system. Switch the system off at the thermostat if you suspect strips are stuck on, and call for service.
Why did my bill spike so suddenly?
Sudden spikes usually mean something changed electrically — a sequencer or contactor stuck closed, energizing the strips continuously. Gradual increases more often point to the heat pump losing efficiency and leaning on backup heat. The pattern helps the diagnosis.
Will this repair void my Amana warranty?
No, provided qualified technicians do the work with correctly matched components. Warranty-safe repair is designed specifically to preserve your manufacturer’s coverage.
