Your electric bill in Parrish spiked — and the prime suspect is the heat strips in your Bryant system. Electric resistance heat is the most expensive heat a home can produce, and when the strips misbehave (stuck on, staging wrong, running when they should not), the meter spins at the worst possible rate. This page is the bill investigation — why strips cause high bills, how to confirm they are the culprit, and what the replacement involves. With 24/7 emergency HVAC service in Parrish, the investigation starts the same day.
Why Heat Strips Cause High Bills
Heat strips are electric resistance elements — essentially high-powered toasters inside your air handler. They convert electricity directly to heat at a 1:1 ratio, making them the costliest heating method available. They exist as backup — auxiliary heat bridging the gap when the heat pump cannot meet demand alone, or emergency heat when the heat pump cannot run. The economics work only when strips run rarely and briefly. When they run constantly, run when unneeded, or run stuck-on, the bill reflects resistance heat at full blast — the spike you are seeing.
The Investigation: Are the Strips the Culprit?
- The bill pattern. Did the spike coincide with heating season? Is it dramatically higher than the same period last year? Strip-caused spikes are seasonal and sudden — the signature of resistance heat running amok.
- The aux heat indicator. Is the thermostat showing auxiliary heat or emergency heat active constantly? Persistent auxiliary heat means the strips are carrying the load — normal briefly in extreme cold, abnormal as a sustained pattern.
- The system behavior. Is the heat pump itself running? If the outdoor unit is idle while the bills soar, the strips are heating alone — the most expensive scenario.
- The amperage test. The technician measures the strips’ electrical draw — confirming whether they are energized, how much current they are drawing, and whether the draw matches the thermostat’s call. The meter does not lie.
Stuck Strips: the Classic Cause
The most common strip failure: a sequencer or contactor welded shut — the strips locked on, heating continuously regardless of thermostat demand. The home overheats, the system short-cycles or runs endlessly, and the bill explodes. Stuck strips are an electrical fault (the control that should cycle them has failed closed), and they are confirmed by the amperage test: strips drawing full current with no call for heat. The fix is the sequencer or contactor replacement — and the strip elements themselves inspected for damage from the overheating.
Staging Failures: the Subtle Cause
Heat strips are staged — brought on in steps as demand increases, not all at once. When staging fails (sequencer malfunction, control logic fault), all stages energize together for every call — the system using maximum resistance heat for minimum demand. The bills spike without the dramatic stuck-on symptoms; the home heats “normally” but at ruinous cost. The diagnostic verifies the staging sequence: each stage energizing in order as demand rises, and — critically — de-energizing as demand drops.
When the Strips Themselves Need Replacement
- Burned-out elements. Nichrome elements eventually fail — open circuits, hot spots, physical breakage. (The nichrome element is the heating wire itself; its lifespan is finite under thermal cycling.)
- Damaged from stuck operation. Elements overheated by a failed-closed sequencer — warped, brittle, unsafe to continue in service.
- Corroded connections. Terminals and wiring degraded by years of heat cycling — the electrical path compromised, the resistance increased.
- Undersized or mismatched. The wrong strip kit for the system or the home’s load — replaced with the correctly specified assembly.
The Replacement: What It Involves
Heat strip replacement is electrical work inside the air handler: power verified off and locked out, the old strip assembly removed, the new assembly installed (correct kilowatt rating, correct staging configuration, correct physical fit), sequencers and contactors verified or replaced, all wiring inspected and tightened, and the full staging sequence tested — each stage energizing and de-energizing on command, with amperage measured and recorded per stage. Bryant’s Evolution communicating controls, where equipped, integrate the strip staging with the heat pump’s operation — the replacement is verified as a complete system, not just swapped parts.
Preventing the Next Bill Spike
- Annual electrical inspection. Sequencers, contactors, and strip elements checked and tested — the stuck-on failure caught before it reaches the bill.
- Thermostat vigilance. The auxiliary heat indicator watched — persistent auxiliary heat is the early warning that strips are over-running.
- Heat pump health. The strips compensate for a struggling heat pump — keeping the heat pump itself maintained reduces strip runtime at the source.
- Bill monitoring. The monthly bill treated as the strip monitor — the spike investigated promptly, not after three months of overpayment.

Why did my electric bill spike so high?
The prime suspect is the heat strips — electric resistance auxiliary heat running constantly, stuck on, or staging incorrectly. The investigation (bill pattern, aux indicator, system behavior, amperage test) confirms or exonerates them.
What does “stuck strips” mean?
A sequencer or contactor welded shut — the strips locked on, heating continuously regardless of thermostat demand. Confirmed by amperage measurement; fixed by replacing the failed control and inspecting the elements for heat damage.
How are heat strips supposed to work?
As staged auxiliary heat — energizing in steps only when the heat pump cannot meet demand alone, then de-energizing as demand drops. Brief, occasional, controlled. Constant or full-blast operation is the malfunction.
What does strip replacement involve?
Electrical work in the air handler: the correctly rated strip assembly installed, sequencers verified or replaced, wiring inspected and tightened, and the full staging sequence tested with amperage measured per stage.
