Why Your Electric Bill Spiked: The Heat Strip Connection

A sudden jump in your electric bill during heating season in Bradenton can have several causes, including heat strips that are stuck on or being activated more than necessary. Heat strips are electric resistance heating elements inside your air handler. They can support your Heil heat pump during defrost, cold weather, or recovery from a thermostat setback, depending on the system and its controls. They create heat directly and can use more electricity than a heat pump’s normal heating cycle. A high bill alone, however, cannot show whether the strips are involved or identify a failed part.

A heat pump problem, thermostat settings, weather, and changes in energy use can also affect a bill. A failed strip may reduce available backup heat rather than cause a high-bill spike. Diagnosis matters: replacing strips will not address a bill driven by another issue, and a heat pump repair may not correct strips that are stuck on or being called unnecessarily.

How Heat Strips Work, and When They May Run

Think of your heating system as having two sources of heat. The heat pump moves heat from the outdoor air into your home. Heat strips are electric resistance elements in the air handler that generate heat directly, much like a toaster. Depending on the equipment and controls, the thermostat may call for strip heat to assist the heat pump, including during defrost or recovery from a large setback.

How often heat strips should run varies by system and conditions. If your thermostat shows auxiliary or emergency heat for long stretches, especially during mild weather, note when it happens and arrange an assessment. Possible causes include a heat pump that is not keeping up, thermostat settings or wiring, or a control that is keeping the strips energized. The indicator alone does not identify the cause.

Observations That May Help Identify a Heat Strip Problem

  • Electric bills climbing with no obvious change in weather or usage. Compare the same billing period year over year and consider changes in rates, occupancy, and thermostat settings. A bill increase does not by itself point to the heat strips.
  • The auxiliary or emergency heat indicator stays on. Many thermostats display when backup heat is active. Note how long the indicator stays on and the conditions, but do not treat it as proof of a failed part.
  • A persistent burning or electrical smell. A brief dusty smell when heating first runs can occur, but a persistent hot or electrical smell needs prompt attention.
  • A breaker trips when heating starts. Repeated trips need professional attention. Do not keep resetting the breaker.
  • Uneven heat or lukewarm air. These symptoms can have several causes, including issues beyond the strip bank, and require diagnosis.

Diagnosis First: Heat Strips or Heat Pump?

A proper service visit checks the system before parts are ordered. A qualified technician can review thermostat staging and use electrical measurements to determine whether the strip elements are operating as called for. The technician can also inspect the sequencer, relay, and other controls to find out whether the strips are being energized when they should not be.

The heat pump should be assessed as well. A technician can check its heating performance and reversing-valve operation; refrigerant diagnostics may also be appropriate. If refrigerant is handled, it should be handled by an EPA-qualified technician. If the heat pump is underperforming, addressing that issue may reduce unnecessary reliance on backup heat. If the heat pump is operating properly but the strips or their controls are faulty, the technician can explain the appropriate repair or replacement. Measurements help guide the recommendation; symptoms alone do not prove a failed part.

What Heat Strip Replacement Involves

When testing confirms a problem with the strip bank, replacement is an electrical repair in the air handler. A qualified technician disconnects power, removes the heater kit, and installs a replacement matched to the Heil equipment’s electrical rating and airflow requirements. The technician should also check the sequencers, relays, and thermal limits, since a control problem can affect a replacement kit.

Because heat strips draw substantial current, the technician checks electrical connections to the equipment manufacturer’s specifications and verifies operation under load. The thermostat staging is checked so the strips support the heat pump as intended. Work duration depends on the equipment and the findings, and the system should be tested before the service visit is complete.

Keeping Bills Down After the Repair

After the system is repaired, a few habits may help limit unnecessary strip operation. Large thermostat setbacks can prompt supplemental heat during recovery on some systems, so use settings suited to your equipment. Keep the area around the outdoor unit clear of debris without opening the equipment or reaching into it. A preseason heating check can include review of thermostat staging, electrical operation, and controls.

Heil Heat Strip FAQs

How do I know whether the high bill is from the heat strips or just a cold month?

Compare the same billing period year over year and consider weather, rates, and changes in household use. If your thermostat’s auxiliary heat indicator stays on for long stretches, note when it happens and share that information with the technician. The indicator and bill are clues, not confirmation; a technician can test the system to determine what is happening.

Is it safe to run the system while waiting for replacement?

That depends on the system’s symptoms. If you notice a persistent burning or electrical smell, smoke, or repeated breaker trips, turn the system off at the thermostat if it is safe to do so and call for service promptly. Do not open the air handler or repeatedly reset a breaker. If there is smoke or fire, leave the area and contact emergency services. If none of these warning signs is present, ask the service provider whether it is appropriate to keep using the system while you wait.

How long does heat strip replacement take?

Timing depends on the equipment, the diagnosis, and whether additional repairs or parts are needed. The technician can provide an estimate after inspecting the system and explain the work and testing required.

Should I repair the strips or replace the whole system?

If the heat pump is in good condition and the issue is limited to the strip kit or its controls, repair may be appropriate. If the system is aging, uses an outdated refrigerant, or needs multiple major repairs, compare the repair scope and cost with replacement options. An honest technician can explain both options based on the equipment’s condition.

Will new heat strips lower my electric bill?

Not necessarily. If testing confirms that strips were stuck on or being activated unnecessarily, correcting that issue may reduce avoidable electricity use. Replacing a failed strip does not guarantee a lower or normal bill. Weather, rates, household use, heat pump performance, and system settings also affect energy costs.
