High Bill in Brandon? Start With the Heat Strips
If your electric bill in Brandon climbed sharply without any change in how your household uses power, the auxiliary heat strips in your Amana system are the first thing to investigate. Heat strips are electric resistance elements — large coils inside the air handler that supplement the heat pump on the coldest mornings and during defrost cycles. Healthy strips run briefly, then hand heating back to the heat pump. Failing strips stay energized, sometimes around the clock, quietly adding hundreds of dollars to the bill while the house feels perfectly comfortable.
This page covers one job: diagnosing, repairing, or replacing the heat strips on an Amana system in Brandon, and knowing which of those three you actually need.
What Normal Heat Strip Behavior Looks Like
Knowing “normal” is half the diagnosis. On a typical Brandon winter day, the heat pump handles most of the heating. The strips switch on only when the thermostat calls for auxiliary heat — during a defrost cycle, when the outdoor coil ices over, or when the indoor temperature lags the setpoint by a few degrees. You may see “Aux Heat” on the thermostat for minutes at a time, and the supply air feels noticeably warmer during those short bursts.
Normal behavior has a signature: short runs, almost no strip activity in mild weather, and the indicator going dark once the setpoint is reached. Abnormal behavior has a different signature: the “Aux Heat” light glowing for hours, the outdoor unit cycling normally while the meter spins fast, or a bill that doubled even though the house was warm. If that sounds familiar, keep reading before you assume you need a whole new system.
Five Checks You Can Make Before Calling
These are safe, no-tool observations any homeowner can make. They will not fix the problem, but they give the technician a precise starting point.
- Watch the thermostat indicator. Note when “Aux Heat” or “Emergency Heat” appears and how long it stays on. Hours of aux heat on a mild day is abnormal.
- Confirm the mode and setpoint. Make sure the system is in Heat, not Emergency Heat, and that the setpoint is reasonable. Emergency Heat runs the strips exclusively and is the most expensive way to heat a home.
- Feel the supply vents during a heat call. If air from the vents is very hot for long stretches, the strips are likely energized. Lukewarm air with the outdoor unit running normally points more toward the heat pump side.
- Check the breaker panel. The heat strips have their own large breakers. A tripped strip breaker explains no heat; it never explains high bills. Do not reset repeatedly — a breaker that trips again is protecting you from a fault.
- Compare bills month to month. A sudden jump that lines up with colder weather, while usage habits stayed the same, is the classic fingerprint of stuck-on strips.
Write down what you find. That short list becomes the technician’s roadmap.
What a Technician Tests on a Heat Strip Call
A strip diagnosis is electrical work, and the measurements are specific. Here is what the visit actually covers:
- Sequencer operation. The sequencer stages the elements on and off in order. A stuck sequencer keeps elements energized after the call ends — the most common cause of runaway strip operation.
- Element resistance. Each resistance element is tested against its rated value. An open element produces no heat; a partially failed one draws current without delivering its share, forcing longer runtimes.
- Amp draw under load. Clamp-meter readings confirm whether the strips draw current when they should be off, and whether each stage draws what its rating specifies.
- Contactor and control voltage. Welded or pitted contactor points can hold strips on with no thermostat call. Low control voltage can leave contactors chattering instead of seating cleanly.
- Thermostat and wiring. A miswired or misconfigured thermostat can call for aux heat continuously. This is checked before any part is condemned.
The goal is a measured answer: which stage failed, which control failed, and whether the fix is a component or the whole strip assembly.
Repair or Replace: The Heat Strip Decision
Repair makes sense when the fault is isolated: a single bad sequencer, one failed element, or a contactor that has seen better days. These are contained electrical repairs, and the rest of the assembly keeps serving.
Replacing the strip assembly is the better call when elements show uneven resistance across stages, when the assembly has overheated repeatedly, when the existing strips are undersized for the home and have been overworking for years, or when a repair would cost close to the assembly itself. A technician who has measured the actual amp draw can show you exactly where your system sits on that line.
One thing replacement never does on its own: fix the cause. If a failing control board or thermostat keeps calling for aux heat, new strips will fail the same way. That is why the electrical diagnosis comes first, always.
Amana Equipment Notes
Amana systems are built around durable components — including Million-Air stainless-steel heat exchanger engineering on applicable models — and their control logic expects genuine parts. Aftermarket sequencers and contactors can fail to mate with the unit’s control timing, leading to chattering, short staging, or nuisance trips. We service Amana equipment with genuine parts, and our technicians are EPA certified for refrigerant handling wherever the refrigerant circuit is touched. Repairs are performed in a way that protects your manufacturer warranty, since uncertified work can void it.
Keeping Strips Off Your Bill After the Fix
Once the strips are behaving, a short maintenance habit keeps them that way: have the electrical connections in the air handler checked during annual service, keep the thermostat configured for your actual equipment, and call if “Aux Heat” starts lingering again. Early calls are cheap calls — a stuck sequencer caught in week one costs far less than a quarter of runaway strips.
Questions About Amana Heat Strip Replacement
Why did my electric bill suddenly double?
The most common cause on a heat pump system is heat strips that stay energized — a stuck sequencer or welded contactor can hold resistance elements on around the clock. The house still heats normally, so the only symptom is the bill. An amp-draw test confirms it quickly.
Are heat strips supposed to run often?
Briefly, yes — during defrost cycles and on the coldest mornings. If the aux-heat indicator glows for hours on a mild Brandon day, that is not normal operation and it is worth a service call.
Can I just disconnect the heat strips to save money?
Do not. Disconnecting strips removes your backup heat and your defrost safety net, and it can leave the home cold if the heat pump cannot keep up. The fix is a diagnosis, not a disconnection.
How long does a heat strip repair take?
Most strip diagnostics and component repairs are completed in a single visit, typically one to two hours depending on access to the air handler. Full assembly replacements may take longer if the air handler sits in a tight attic or closet space.
Will this happen again?
Not if the root cause is addressed. A quality repair includes checking the sequencer, contactors, thermostat call, and control wiring — not just swapping the failed part. Annual service keeps the electrical connections tight and the staging correct.
For Amana heat strip diagnosis, repair, or replacement in Brandon, scheduling is available with same-day dispatch and 24/7 emergency service. One call gets a technician to your door with the meters and parts to measure the problem and fix it in one visit.
