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 Allegan. Or it is producing cool air from the supply registers when the thermostat is set to heat in Allegan, MI. 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 Allegan. 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 Allegan, MI.
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 Allegan. The reversing valve that switches the refrigerant flow direction between heating and cooling modes in Allegan, MI. The defrost board and defrost sensor that manage the defrost cycle that prevents the outdoor coil from icing over in cold weather in Allegan. The supplemental heat strips that provide additional heating capacity when the heat pump alone cannot meet the heating load at low outdoor temperatures in Allegan, MI. A technician experienced only with standard AC systems or only with furnaces may misdiagnose heat pump-specific faults in Allegan.

The refrigerant circuit in a heat pump operates differently in heating mode than in cooling mode in Allegan. The component that is the condenser in cooling mode becomes the evaporator in heating mode in Allegan, MI. 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 Allegan.
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 Allegan, MI.
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 Allegan. 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 Allegan, MI.
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 Allegan, MI.
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 Allegan. In cooling mode, similar causes apply as with standard AC systems in Allegan, MI.
A defrost system fault preventing defrost cycles from occurring or completing causes the outdoor coil to ice over completely in Allegan, MI. Low refrigerant can also cause outdoor coil icing. Heavy ice accumulation significantly reduces heat pump heating efficiency and warrants prompt service in Allegan.
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 Allegan.
The reversing valve changes the direction of refrigerant flow between heating and cooling modes in Allegan, MI. A reversing valve stuck in one position prevents the system from operating correctly in the other mode in Allegan. A partially stuck reversing valve reduces efficiency in one or both modes in Allegan, MI. MBM diagnoses reversing valve faults as a standard component of every heat pump service in Allegan.
The defrost board monitors the outdoor coil temperature and initiates defrost cycles when needed in Allegan. A failed defrost sensor sending incorrect temperature readings causes either defrost cycles that never occur or defrost cycles that run constantly in Allegan, MI. MBM diagnoses defrost system faults by assessing both the board and sensor performance in Allegan.
Supplemental heat strips provide electric resistance heating when the heat pump alone cannot meet the heating load at low outdoor temperatures in Allegan, MI. Failed heat strips produce reduced heating capacity at low outdoor temperatures in Allegan. Failed sequencers prevent heat strips from activating in the correct sequence in Allegan, MI.
The refrigerant circuit in a heat pump operates at different pressures in heating and cooling mode in Allegan. MBM assesses heat pump refrigerant pressures in the mode where the fault is presenting with the mode-appropriate pressure expectations in mind in Allegan, MI.
The heat pump thermostat and control system manage the transition between modes, the engagement of supplemental heat, and the defrost cycle in Allegan, MI. A control system fault can produce a wide range of heat pump symptoms in Allegan.
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 Allegan. MBM assesses outdoor unit components in the context of the operating conditions during the service visit in Allegan, MI.
A standard air conditioner moves heat from indoors to outdoors in one direction in Allegan, MI. 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 Allegan. In heating mode, the outdoor unit extracts heat from the outdoor air even when outdoor temperatures are well below freezing in Allegan, MI.
The reversing valve is the mechanism that makes the heat pump's dual-mode capability possible in Allegan. Most heat pumps energize the reversing valve in cooling mode and allow it to relax to its natural position in heating mode in Allegan, MI. Stuck in the cooling position produces inadequate or no heating in Allegan. Stuck in the heating position produces inadequate or no cooling in Allegan, MI.
A gas furnace produces supply air temperatures of 120 to 140 degrees Fahrenheit in Allegan. A heat pump in heating mode produces supply air temperatures of 90 to 100 degrees Fahrenheit under normal operating conditions in Allegan, MI. The heat pump supply air feels cooler than gas furnace supply air even when the heat pump is operating correctly in Allegan. This often leads homeowners to believe the heat pump is not heating when it actually is in Allegan, MI. If the supply air temperature is below 85 to 90 degrees Fahrenheit in mild weather, a fault investigation is warranted in Allegan.
During a defrost cycle, you may notice steam rising from the outdoor unit as the ice melts in Allegan. The outdoor fan may stop running during defrost in Allegan, MI. The supply air temperature indoors may drop temporarily as the heat pump diverts energy to the outdoor defrost in Allegan. These are all normal defrost cycle characteristics in Allegan, MI. 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 Allegan.
