Both heating mode and cooling mode faults. Heat pump-specific component diagnosis including reversing valve, defrost system, and supplemental heat. Performance verified in the affected mode. Every repair guaranteed.
Your heat pump is not heating the home correctly in Manitowoc. Or it is producing cool air from the supply registers when the thermostat is set to heat in Manitowoc, WI. Heat pumps provide both heating and cooling from a single system and their faults can present differently depending on which mode the system is operating in at the time in Manitowoc. A heat pump that is not heating in winter may have a completely different fault than a heat pump that is not cooling in summer in Manitowoc, WI.
What makes heat pump diagnosis genuinely different from standard AC or furnace diagnosis is the specific components that heat pumps have that neither standard AC systems nor furnaces have in Manitowoc. The reversing valve that switches the refrigerant flow direction between heating and cooling modes in Manitowoc, WI. The defrost board and defrost sensor that manage the defrost cycle that prevents the outdoor coil from icing over in cold weather in Manitowoc. The supplemental heat strips that provide additional heating capacity when the heat pump alone cannot meet the heating load at low outdoor temperatures in Manitowoc, WI. A technician experienced only with standard AC systems or only with furnaces may misdiagnose heat pump-specific faults in Manitowoc.

The refrigerant circuit in a heat pump operates differently in heating mode than in cooling mode in Manitowoc. The component that is the condenser in cooling mode becomes the evaporator in heating mode in Manitowoc, WI. A technician reading heat pump refrigerant pressures without understanding how they differ between modes may misinterpret a normal heating mode reading as a fault, or miss an actual fault because the reading seems normal compared to cooling mode expectations in Manitowoc.
Low refrigerant reducing heating capacity. A reversing valve stuck in or toward cooling position producing inadequate heating output. A defrost system fault allowing the outdoor coil to ice over. Or failed supplemental heat strips not engaging to provide additional heating capacity at low outdoor temperatures in Manitowoc, WI.
A reversing valve stuck in the cooling position is the most common cause, directing refrigerant flow in the cooling direction regardless of the thermostat's heating command in Manitowoc. Low refrigerant can also produce cool supply air in heating mode. Emergency heat mode activated on the thermostat without the heat pump operating is another possibility in Manitowoc, WI.
Low refrigerant reducing cooling capacity. A dirty or blocked outdoor coil reducing heat rejection efficiency. A failed outdoor fan allowing the coil to overheat. A failed compressor. A reversing valve that is partially stuck may also reduce cooling efficiency in Manitowoc, WI.
In heating mode, low refrigerant, a defrost system problem keeping the outdoor coil partially iced, or an undersized system for the specific climate's heating demands in Manitowoc. In cooling mode, similar causes apply as with standard AC systems in Manitowoc, WI.
A defrost system fault preventing defrost cycles from occurring or completing causes the outdoor coil to ice over completely in Manitowoc, WI. Low refrigerant can also cause outdoor coil icing. Heavy ice accumulation significantly reduces heat pump heating efficiency and warrants prompt service in Manitowoc.
A failing capacitor causing the compressor to struggle at startup. Incorrect refrigerant charge causing safety switch trips. A defrost system issue causing unnecessary defrost cycles that interrupt normal operation. Or a control system fault producing premature shutdown commands in Manitowoc.
The reversing valve changes the direction of refrigerant flow between heating and cooling modes in Manitowoc, WI. A reversing valve stuck in one position prevents the system from operating correctly in the other mode in Manitowoc. A partially stuck reversing valve reduces efficiency in one or both modes in Manitowoc, WI. MBM diagnoses reversing valve faults as a standard component of every heat pump service in Manitowoc.
The defrost board monitors the outdoor coil temperature and initiates defrost cycles when needed in Manitowoc. A failed defrost sensor sending incorrect temperature readings causes either defrost cycles that never occur or defrost cycles that run constantly in Manitowoc, WI. MBM diagnoses defrost system faults by assessing both the board and sensor performance in Manitowoc.
Supplemental heat strips provide electric resistance heating when the heat pump alone cannot meet the heating load at low outdoor temperatures in Manitowoc, WI. Failed heat strips produce reduced heating capacity at low outdoor temperatures in Manitowoc. Failed sequencers prevent heat strips from activating in the correct sequence in Manitowoc, WI.
The refrigerant circuit in a heat pump operates at different pressures in heating and cooling mode in Manitowoc. MBM assesses heat pump refrigerant pressures in the mode where the fault is presenting with the mode-appropriate pressure expectations in mind in Manitowoc, WI.
The heat pump thermostat and control system manage the transition between modes, the engagement of supplemental heat, and the defrost cycle in Manitowoc, WI. A control system fault can produce a wide range of heat pump symptoms in Manitowoc.
The outdoor fan motor, capacitor, and contactor are exposed to cold temperatures in heating season that affect their performance differently than in cooling season in Manitowoc. MBM assesses outdoor unit components in the context of the operating conditions during the service visit in Manitowoc, WI.
A standard air conditioner moves heat from indoors to outdoors in one direction in Manitowoc, WI. A heat pump does the same in cooling mode but adds the ability to reverse that process in heating mode, moving heat from the outdoor air into the home in Manitowoc. In heating mode, the outdoor unit extracts heat from the outdoor air even when outdoor temperatures are well below freezing in Manitowoc, WI.
The reversing valve is the mechanism that makes the heat pump's dual-mode capability possible in Manitowoc. Most heat pumps energize the reversing valve in cooling mode and allow it to relax to its natural position in heating mode in Manitowoc, WI. Stuck in the cooling position produces inadequate or no heating in Manitowoc. Stuck in the heating position produces inadequate or no cooling in Manitowoc, WI.
A gas furnace produces supply air temperatures of 120 to 140 degrees Fahrenheit in Manitowoc. A heat pump in heating mode produces supply air temperatures of 90 to 100 degrees Fahrenheit under normal operating conditions in Manitowoc, WI. The heat pump supply air feels cooler than gas furnace supply air even when the heat pump is operating correctly in Manitowoc. This often leads homeowners to believe the heat pump is not heating when it actually is in Manitowoc, WI. If the supply air temperature is below 85 to 90 degrees Fahrenheit in mild weather, a fault investigation is warranted in Manitowoc.
During a defrost cycle, you may notice steam rising from the outdoor unit as the ice melts in Manitowoc. The outdoor fan may stop running during defrost in Manitowoc, WI. The supply air temperature indoors may drop temporarily as the heat pump diverts energy to the outdoor defrost in Manitowoc. These are all normal defrost cycle characteristics in Manitowoc, WI. A correctly functioning defrost system runs for a few minutes every hour or two in conditions that produce frost accumulation, then returns to normal heating operation in Manitowoc.
