Prompt Heat Pump Repair Alpharetta GA
Heat pump repair is common in Alpharetta because these systems operate year-round and handle both heating and cooling needs. During long, humid summers, heat pumps work hard to remove moisture while keeping indoor temperatures steady. That constant runtime strains the coils, drainage systems, and electrical components. When summer performance slips, small issues often carry into winter and show up as airflow problems, icing, or reduced heating output.
Cold snaps in January also create stress because systems shift into higher-stage heating and rely more heavily on defrost controls and sensors. If refrigerant levels drop or a defrost board fails, the unit may run backup electric heat too often, quickly increasing energy bills. Alpharetta homeowners often need repairs when AUX heat runs nonstop, outdoor units ice over, or efficiency drops during moderate weather. Prompt service helps restore normal operation and prevents seasonal wear from turning into major breakdowns.
Common Heat Pump Problems We Diagnose And Repair
Contact us for service if your heat pump is freezing, blowing cold air, or driving up your energy bills.
Stuck In Defrost Or Outdoor Unit Icing
Heavy ice buildup on the outdoor coil usually indicates a failed defrost control board, a faulty defrost thermostat, or a defective outdoor temperature sensor. When the defrost system does not run correctly, airflow drops, and the unit cannot heat properly.
Blowing Cold Air In Winter
Cold air from the vents in heat mode is a sign of a reversing valve issue. If the valve cannot switch refrigerant flow into heating mode, the system may stay stuck in cooling. Failed auxiliary heat strips can also prevent the home from warming up.
AUX Heat Running Constantly
If AUX heat stays on, your system is relying on expensive backup electric heat instead of normal heat pump operation. This is often caused by low refrigerant levels, sensor failures, or defrost system issues.
Tripped Breaker
A heat pump that trips the breaker may have a failing capacitor, a damaged contactor, or an electrical issue with the compressor. This requires immediate service, as repeated breaker trips can cause equipment damage or pose safety risks.
Humming Capacitor
A loud hum from the outdoor unit often means the capacitor is weakening or failing. Capacitors are needed to start the compressor and fan motor, and replacement is usually a quick repair that prevents larger motor failures.
Grinding Or Screeching Blower Motor
Grinding or squealing noises from the indoor unit typically indicate worn blower motor bearings or belt issues in older systems. If airflow stops, the system may shut down, and comfort will drop quickly throughout the home.
Low Or No Airflow
Weak airflow can result from clogged air filters, blocked ducts, or failing blower motors. Poor circulation prevents proper heating and cooling and strains the system.
Short Cycling
If your heat pump turns on and off too frequently, it may have thermostat issues, a refrigerant imbalance, or electrical control problems. Short cycling reduces efficiency and increases damage to the system.
Unresponsive Thermostat
A faulty thermostat or loose wiring can prevent your heat pump from turning on, changing modes, or maintaining set temperatures. This can sometimes mimic more serious equipment failures.
Rising Energy Bills
Sudden increases in utility costs, especially during moderate weather, often signal heat pump inefficiency. These are usually caused by refrigerant leaks, sensor malfunctions, or failed components.

Component-Level Heat Pump Repair
We service critical components such as reversing valves, defrost boards, capacitors, TXVs, sensors, and accumulators to keep your heat pump operating.
Reversing Valve Service
The reversing valve controls whether your heat pump runs in heating or cooling mode. If it fails, the system may blow cold air in winter, stay stuck in one mode, or develop refrigerant leaks. We test valve operation, check the solenoid coil, and repair or replace the valve when needed.
Defrost Control Board Diagnosis
Defrost boards prevent outdoor coil icing by controlling when the system enters and exits defrost mode. A failed board can cause heavy ice buildup, nonstop defrost, or no defrost cycle at all. We test sensors, wiring, and control signals, then replace the board if necessary.
Capacitor Testing And Replacement
Capacitors help start and run the compressor and fan motors. Weak or failed capacitors can prevent the system from starting or cause electrical strain. We measure capacitance values and replace faulty units to prevent motor damage.
Expansion Valve (TXV) Service
The TXV regulates refrigerant flow through the system. When it fails, the heat pump may freeze up, struggle to heat or cool, or run inconsistently. We check superheat readings and valve response, then replace the component if metering is incorrect.
Refrigerant Leak Detection And Repair
Low refrigerant levels reduce heating and cooling capacity and often indicate a leak. We locate leaks using electronic detection and pressure testing, complete the repair, evacuate moisture, and recharge the system to manufacturer specifications.
Outdoor Ambient Sensor Service
Outdoor temperature sensors help control AUX heat use and defrost timing. A bad sensor can trigger unnecessary backup heat or defrost problems. We test resistance readings and install the correct replacement sensor when needed.
Accumulator Inspection
Accumulators protect the compressor from liquid refrigerant during mode changes. Damage or internal failure can pose a risk to the compressor. We inspect for corrosion, frost patterns, and proper refrigerant separation during major system repairs.

Heat Pump Repair For Today's Systems
We repair all types of heat pumps, including electric and geothermal systems.
Electric Heat Pumps
Electric heat pumps are the most common residential heating systems in Alpharetta, GA, for providing reliable heating and cooling year-round. These systems rely on refrigerant flow, reversing valves, and auxiliary heat strips. When components fail, they may blow cold air, freeze over, or short-cycle. Common repairs include fixing defrost boards, replacing sensors, and restoring refrigerant charge. We work on all sizes and brands of electric heat pumps.
Ground-Source And Geothermal Heat Pumps
Geothermal systems use the ground's steady temperature to heat and cool the home. They are energy-efficient and operate quietly. However, repairs can be more complex due to issues such as loop leaks, circulation pump problems, and sensor or controller faults. We thoroughly inspect and service the system to restore proper operation.
Call (404) 689-4168 to schedule heat pump repair in Alpharetta.
Our Heat Pump Repair Process
Our repair process covers everything from initial symptom checks and full system diagnostics to final testing in both heating and cooling modes. We don't guess - we test, explain, and verify every step.
We Start By Listening To Your Concerns
Every service call begins with a discussion about the issue, the symptoms you've noticed, how your thermostat behaves, and whether your utility bills have changed. This helps us quickly narrow down the problem, especially if it occurs only during heating or cooling.
We Inspect The Outdoor Unit And Electrical Components
Our technician checks for ice buildup, visible damage, or refrigerant leaks. We test electrical connections, examine the capacitor and contactor, and confirm breaker status. If a breaker has tripped, we determine the cause before resetting it.
We Test The Defrost System And All Sensors
We simulate or observe the defrost cycle to make sure it starts and stops properly. We also test outdoor ambient sensors that trigger AUX heat and defrost timing. Indoor temperature sensors, pressure sensors, and safety controls are checked to rule out hidden electrical faults.
We Confirm Refrigerant Charge And Check For Leaks
Using pressure readings, we calculate subcooling and superheat values to see if your refrigerant level is correct. If it's low, we locate and repair the leak, then fully evacuate and recharge the system to spec. We never just "top off" refrigerant without fixing the root cause.
We Explain The Repair And Review Your Options
Once we diagnose the issue, we walk you through the findings in plain language. You'll know what failed, why it happened, and how we plan to fix it. We'll also explain the urgency, timelines, and pricing so you can make informed decisions without surprises.
We Verify Full System Operation Before We Leave
After repairs are complete, we test both heating and cooling modes to confirm proper changeover. We check airflow, temperature output, reversing valve operation, and AUX heat integration. We don't consider the job done until your system runs exactly as it should.
