Heat Strip and Sequencer Replacement Cost in Bay County (2026)

Replacing an auxiliary heat strip or sequencer typically costs $400 to $700 in Bay County, parts and labor included. That is a typical market range, not a Quincy’s quote. Most strip faults are found on the first cold morning of the year, because the strips sit idle through the long cooling season and the first hard cold is the first real test they get.

Here is what each part of a strip kit does, the signs that one has failed, why airflow is usually behind it, and when a strip repair on an older system should come with a replacement price next to it.

What the strips, sequencer, limits and fusible links each do

In a Bay County heat pump home the backup heat lives in the indoor air handler, sitting in the airstream just past the blower. A strip kit is a small team of parts:

• Heating elements. Open coils of resistance wire that get red hot when powered. Most kits have two or more, wired in stages.
• Sequencer. A time-delay switch that brings the elements on one after another instead of all at once, so your electrical service never takes the whole load in a single instant. It drops them out in turn as well. Some newer air handlers use relays for the same staging job.
• Limit switches. Temperature switches on the elements that open if things overheat, almost always because air is not moving, and close again once they cool.
• Fusible links. One-time thermal cutoffs that melt open if a limit fails to stop the overheating. Once open, a link stays open until it is replaced, and it tells the technician the element got dangerously hot.
• Strip kit breakers or relays. Many air handlers carry their own breakers for the strip circuits, plus relays that switch the elements when the thermostat calls for backup heat.

Any one of these can stop the strips. That is why a correct diagnosis matters more than the part number: a new element on a kit with a stuck sequencer still gives you no heat.

Signs a heat strip or sequencer has failed

• No heat on EM HEAT. The cleanest test there is. With the heat pump locked out, the vents should blow noticeably hot air within a few minutes. Cool air means the strips are not working.
• Only part of the heat. One element or stage is out. The heat pump plus half a strip kit leaves the house lagging on cold mornings, and AUX runs longer than it used to.
• A cold draft every defrost. Strips are supposed to temper the air while the outdoor coil defrosts. A blast of cool air each time can mean they are not coming on.
• A burning smell that does not clear. The first run of the season smells of dust burning off the elements, and it fades. A smell that lasts past the first hour, smells electrical, or returns on later days is a reason to switch off and call.
• A breaker that trips when the strips come on. A shorted element, a burned connection or a failing breaker. Reset once, then leave it.
• Heat when the thermostat is satisfied. A sequencer or relay stuck closed can keep an element powered after the call ends. The limit then cycles it on heat alone, and the power bill shows it.

Why a dirty filter or weak blower burns out heat strips

Strips depend on a steady river of air carrying their heat away. Choke that airflow with a clogged filter, blocked returns, a failing blower motor or a dirty indoor coil, and element temperature climbs until the limit opens. The element cools, the limit closes, and the cycle repeats all morning.

Every one of those cycles stresses the element wire and its terminals. Enough of them and an element breaks, a connection burns, or the fusible link finally opens. Replace the element without fixing the airflow and the new one follows the old one. A good strip repair always ends with an airflow check.

What heat strip repairs cost in Bay County

The figures below are typical Bay County market ranges with parts and labor, not a Quincy’s quote. Where no published range exists we describe the job instead of guessing. Every Quincy’s visit starts with a flat trip charge quoted on the phone, and the repair is priced in writing before any work starts.

Our 2026 HVAC pricing guide puts these numbers alongside the rest of the system.

When to fix the strips and when to price a new heat pump

Strip repairs are some of the more sensible money in heating. The work stays inside the air handler, it does not open the refrigerant side, and the strips are what keeps the house warm on the coldest nights and during defrost. A strip failure is worth fixing even on an older air handler.

The exception is age plus a struggling heat pump. Systems here last about 12 to 17 years inland and less near the Gulf. If the air handler is past 15 and the heat pump has been leaning on the strips (long AUX runs, high winter bills), the strips may have burned out doing a job that was never theirs. Fixing them alone leaves the real problem in place. That is the moment to ask for a replacement number next to the repair, and our page on heat pump replacement in Panama City explains what that involves. For why heavy strip use costs so much, see AUX heat vs EM heat and the January bill.

Why heat strip work is a job for a licensed technician

Heat strips run on high-voltage circuits carrying heavy current, and an air handler can be fed by more than one breaker. Turning the thermostat off does not make the strips safe to touch. Never jumper or bypass a limit switch or fusible link to get heat back: those parts are the only thing standing between an overheating element and the air handler cabinet.

The homeowner’s part is short: a clean filter, the thermostat on the right mode, one breaker reset at most. After that, call a Florida licensed contractor.
