These are the signs homeowners notice most, with the usual cause in plain words. - ### Thick ice on the outdoor unit A thin film of frost that melts away is normal. Ice that builds up and stays often points to a defrost problem, a dirty coil or low airflow. - ### Weak or lukewarm air at the vents The system runs but the house never catches up. Common causes are a clogged filter, a failing fan motor or a refrigerant leak. - ### Cool air when you want heat The unit may be stuck in cooling mode. A faulty reversing valve or a control fault can cause it. - ### Frost on the lines or water at the indoor unit Ice on the refrigerant line usually means poor airflow or low refrigerant. As it melts, the water can overflow a clogged drain. - ### A breaker that trips or a unit that will not start A tripped breaker can point to a failing capacitor, a motor drawing too much power or a wiring fault. Reset it once at most. - ### Constant starting and stopping or a new noise Grinding, rattling or repeated short runs often come from a worn fan motor, a loose part or a control problem. ![Indoor air handler with an insulated refrigerant line in a utility closet](/assets/3d2b54d220-800.webp) ## What heat pump repair covers A heat pump heats and cools the same house with an outdoor unit and an indoor coil. Heat pump repair in Spanish Fork covers the faults that stop it doing either job: ice, weak air, a unit that will not start, or one that keeps shutting off. Heat pump repair here means the heat pump itself. If your system is a cooling-only unit, [AC repair in Spanish Fork](/) covers it. If a gas furnace is doing the heating, see [furnace repair in Spanish Fork](/furnace-repair-spanish-fork/). ## How a heat pump works and where it fails In heating mode, the outdoor unit pulls heat out of the outside air and carries it indoors with refrigerant. In cooling mode, a reversing valve flips the flow so the heat goes outside instead. The same parts do both jobs, so one weak part can hurt both seasons. The main parts are the compressor, the outdoor coil and fan, the reversing valve, the indoor coil, the control board and the thermostat. Faults usually start with a dirty coil, a worn fan motor, a failing capacitor, a refrigerant leak, a stuck reversing valve or a defrost control that no longer works. Weather decides how hard the unit works. The average December to February daily low at the NOAA weather station near Spanish Fork is 23.5°F, and the station averages 118 days a year with a low of 32°F or below. It also averages 5,415 heating degree days a year. Summer asks for just as much. The average June to August daily high at the station is 89.8°F, and it averages 1,013 cooling degree days a year. A heat pump's outdoor unit works against outdoor air in both seasons. ## Icing and defrost symptoms When the outdoor coil collects frost, the unit runs a defrost cycle: it briefly reverses, the fan may stop, and steam can rise from the coil. That is normal. It becomes a fault when the ice builds thick, stays for long stretches, or covers the whole coil and fan area. The cause may be a failed defrost sensor, a bad control board, poor airflow or low refrigerant. If you see heavy ice, switch the system off at the thermostat and let it melt on its own. Do not chip at it, because the fins and tubing damage easily. Ice on the indoor refrigerant line or water at the indoor unit is a separate sign. [Ice and water at the indoor unit](/ice-on-ac-lines-water-around-indoor-unit/) explains what to switch off and check. ## Weak heating or cooling When the air from the vents feels lukewarm, the cause can be simple or serious. A clogged filter, closed vents or a blocked return can starve the system of air. A failing blower motor, a leak that lowers the refrigerant charge, or a stuck reversing valve points to a repair. A sign worth noting is the unit blowing cool air in winter. That often means the system is stuck in cooling mode or the defrost cycle is not finishing. Short, repeated runs are a different problem, and [this explanation of short cycling](/ac-short-cycling/) covers it. ## Safe checks before you call These checks are safe for most homeowners and sometimes clear the problem: - Check that the thermostat is set to heat or cool as you intend, and replace its batteries if it has them. - Look at the air filter and swap it if it is dirty. [Filter checks](/how-often-to-change-hvac-air-filter/) covers how often. - Reset the breaker once. If it trips again, leave it off. - Move leaves, snow and debris off the pad around the outdoor unit. Keep fingers and tools out of the fan grille. - Make sure the supply vents and return grilles are open and not blocked by furniture. If the whole house has lost power, that is a power question, not a heat pump fault. Spanish Fork Power & Light provides electric service to homes and businesses in Spanish Fork. For a unit that will not turn on at all, [these thermostat, breaker and outage checks](/ac-wont-turn-on/) go through the steps. ## Safety first Some heat pumps pair with a gas furnace as backup heat, so gas and carbon monoxide still matter. If you smell gas, leave the house, then call the gas utility from outside. If a carbon monoxide alarm sounds, get everyone out and call emergency services. Do not open the outdoor unit or the indoor cabinet. Refrigerant, electrical parts, wiring and sealed components are work for a licensed contractor. ## What a contractor does on a visit We connect you with a licensed, insured HVAC contractor. The call starts when you tap the call button. Where a contractor is available, the line connects the call to that contractor, who then confirms availability and fees. On a visit, a licensed contractor checks airflow, the thermostat and controls, the electrical connections, the fan and compressor, the defrost components and the refrigerant circuit. The aim is to find the cause, explain what failed and set out the options. [What to expect from a repair visit](/what-to-expect-ac-repair-visit/) lists questions worth asking. ## Repair or replace A single failed capacitor or fan motor is usually a repair. A leaking coil, a failed compressor or repeated faults in an older system can make replacement the better choice to weigh. [This comparison of heat pumps with furnace and AC setups](/hvac-spanish-fork/heat-pump-vs-furnace-and-ac/) helps when you are weighing a change of equipment. Ask the contractor whether the job needs a permit. Spanish Fork City lists HVAC replacements among the common projects covered by a residential permit. ## What changes the cost Several things make a heat pump job larger or smaller: - Which part failed, since a sensor is a different job from a compressor. - Whether the fault is in the refrigerant circuit, the electrical side or the airflow. - How easy the outdoor and indoor units are to reach. - The age and type of the system, and whether parts are still easy to find. - Other work the visit turns up, such as a clogged drain or a damaged coil. Each independent contractor confirms its own fees. ## Routine care that heads off faults Keep the filter clean through the heating and cooling seasons, and keep the outdoor unit clear of leaves, weeds, snow and stored items. If dust builds up on the outdoor coil, turn the power off at the outdoor disconnect, then rinse the coil gently with a garden hose. A seasonal check each spring and fall catches worn parts before heavy use exposes them. [This spring and fall checklist](/hvac-spanish-fork/spring-and-fall-hvac-checklist/) lists what to look at. ## How the call works 1. ### Tap the call button The call goes to a phone line that connects callers with licensed, insured independent contractors. 2. ### Answer the prompts An automated prompt may ask for your ZIP code and the service you need.

A licensed contractor finds the cause of the fault, explains what failed and lays out the options, which may be a repair or a replacement. The work can include checks of airflow, controls, wiring and refrigerant. - ### Which checks are safe to do myself? Check the thermostat mode, setpoint and batteries, look at the air filter, and reset the breaker once. Rake leaves and debris back from the outdoor unit without reaching into it, and make sure vents and returns are open. - ### Is ice on the outdoor unit normal? A thin layer of frost that melts during a defrost cycle is normal. Thick ice that stays, or ice on the refrigerant lines, is a reason to switch the system off and call. - ### What if I smell gas or a carbon monoxide alarm sounds? If you smell gas, leave the house, then call the gas utility from outside. If a carbon monoxide alarm sounds, get everyone out and call emergency services. - ### What determines contractor availability? Service availability and appointment times depend on the independent contractor. The contractor confirms them when the line connects the call, where a contractor is available. - ### Should I repair the heat pump or replace it? It depends on what failed, how old the system is and how often it has needed work. Where a contractor is available, the line connects the call to that contractor, and you can ask about the options and whether the job needs a permit. - ### Who confirms the fees for a repair? Each independent contractor confirms its own fees. ## Ready to call about your heat pump? Have the symptoms in mind: where you see ice, what the air feels like and whether a breaker tripped. Availability depends on the contractor. [Call about heat pump repair availability.
