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

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