If your American Standard system’s electric bills have spiked in Trinity, this page answers common questions about heat strip problems. If your system is equipped with AccuComfort variable-speed technology, its controls and operating conditions can affect when auxiliary heat runs. The exact pattern depends on the equipment, settings, weather, and heating demand.
Why did my electric bill suddenly increase?
Electric resistance heat generally uses more electricity for the same amount of heat than a properly operating heat pump, though the difference varies with conditions and system efficiency. A bill increase alone does not identify a failed part. Possible reasons for higher auxiliary-heat use include a heat pump that is not providing enough heat, a control or thermostat issue, or normal operation during cold weather, defrost, or recovery from a temperature setback. Other changes in household use or weather can also affect the bill.
Compare kilowatt-hours, rather than just dollars, with the same period last year. Note when the increase began and whether the thermostat displayed auxiliary or emergency heat. That information can help a technician assess the system alongside diagnostic tests. Do not open electrical panels or test wiring yourself.
Are the heat strips supposed to run this much?
There is no single amount of auxiliary-heat operation that applies to every American Standard system. Auxiliary heat may operate when the heat pump needs help, during defrost, or when indoor temperature recovery or outdoor conditions call for additional heat. If the thermostat indicates auxiliary heat more often than you expect, or your bills have changed noticeably, record when it happens and arrange an assessment. Frequent use does not by itself prove that a heat strip or another part has failed.
AccuComfort variable-speed equipment, when present, can adjust capacity to meet heating demand, but it does not mean auxiliary heat will never run or establish a universal frequency. A technician can check the system’s operation and settings against the equipment specifications.
What’s the difference between auxiliary heat and emergency heat?
Auxiliary heat is typically called automatically by the system when additional heat is needed. Emergency heat is a thermostat mode that commonly disables heat-pump operation and relies on the backup heat source; exact controls can vary by system. Emergency heat can use more electricity than heat-pump operation, so follow the thermostat and equipment instructions and contact a technician if you need to use it because the heat pump may not be working. Tell the dispatcher whether the thermostat shows auxiliary heat or you selected emergency heat; the distinction can help with diagnosis.
How does the technician diagnose a strip problem?
A technician assesses the heating system as a whole, since increased strip use can have causes elsewhere in the system. Depending on the equipment and symptoms, the assessment may include checking heat-pump operation, thermostat configuration and staging, sensors, strip elements, sequencers, electrical connections, airflow, and safety controls. If the system has AccuComfort variable-speed equipment, its operation may also be assessed as part of the diagnosis.
Electrical measurements and checks inside the equipment are technician work, not homeowner troubleshooting. The results help determine whether a heat strip needs replacement or whether another repair is appropriate. Ask the technician to explain the findings and proposed work before authorizing a repair.
What does replacement involve, and how long does it take?
Heat strip replacement involves electrical work. A qualified technician will isolate power and verify the equipment is safe to work on before opening it. The technician should identify the fault and confirm the correct replacement part and rating for the system. A sequencer or other component should be replaced only if diagnosis shows it is needed. Genuine American Standard parts may be used when available and compatible with the equipment.
After the repair, the technician can check operation, airflow, and applicable safety controls. The time required depends on the diagnosis, equipment, parts availability, and any additional work; ask about the expected timing for your system. Request the scope and price before authorizing replacement, and ask what parts or labor warranty, if any, applies to the proposed work.
How do I help prevent problems from recurring?
Follow the equipment manufacturer’s maintenance guidance and arrange routine professional service. A technician can inspect the heating system and its controls, including the electrical components and airflow, as appropriate for your equipment. At home, replace or clean the filter as directed, keep vents and returns unobstructed, and note changes in thermostat indicators or electricity use.
Use thermostat settings recommended for your system. If you notice a substantial change in auxiliary-heat operation, unusual heating performance, or a sharp increase in electricity use, record what you observe and contact a qualified technician. Do not remove equipment panels or attempt electrical tests.
