Expert Heat Pump Repair
Understanding Ducted Heat Pump Systems in East Texas
Ducted heat pumps are an increasingly popular choice for homeowners in East Texas because they provide both heating and cooling from a single outdoor unit. Instead of burning fuel to create heat, a heat pump transfers thermal energy between your home and the outdoor air using a refrigerant cycle. In the summer, it operates much like a central air conditioner - pulling heat from your indoor air and releasing it outside. In the winter, the cycle reverses, extracting heat from the outdoor air and moving it into your home.
This dual-function design makes heat pumps highly efficient, especially in our East Texas climate where winters are generally mild with occasional cold snaps rather than sustained below-freezing temperatures. However, that dual functionality also means there are more components that can fail, and the system works year-round rather than sitting idle for part of the year like a furnace might.
At 903 HVAC, our technicians have extensive training and hands-on experience with American Standard ducted heat pump systems. We understand the reversing valve, defrost cycles, auxiliary heat staging, and every other component that sets a heat pump apart from a conventional AC system. That specialized knowledge matters when it comes to getting an accurate diagnosis and a lasting repair.
How Heat Pumps Differ from Standard AC Systems
Many HVAC companies treat heat pump repairs like standard air conditioning repairs, but there are critical differences that require specific expertise:
- Reversing valve - This component switches your system between heating and cooling modes. When it fails or gets stuck, your heat pump may only cool, only heat, or not function at all.
- Defrost control board - During cold weather, frost can accumulate on the outdoor coil. Your heat pump has a defrost cycle that periodically melts this frost.
- Auxiliary heat strips - When outdoor temperatures drop too low for the heat pump to extract sufficient heat, electric resistance heat strips supplement the system.
- Metering devices - Heat pumps often use two metering devices (one for each mode) or a bi-directional thermostatic expansion valve. Proper refrigerant metering in both directions is essential for efficient operation.
- Year-round operation - Because heat pumps run in both summer and winter, components experience more total runtime hours than a standalone AC or furnace. This accelerated wear means more frequent maintenance needs and different failure patterns.

Common Issues
Common Ducted Heat Pump Problems We Repair in Tyler, TX
Our technicians have repaired thousands of ducted heat pump systems throughout East Texas. Here are the issues we see most frequently in this region:
When your heat pump fails to produce warm air during cooler months, the problem could stem from several sources:
- Stuck reversing valve - If the valve is stuck in cooling mode, your system cannot switch to heating. Our technicians can determine whether the valve itself or the solenoid coil needs replacement.
- Low refrigerant charge - A heat pump with insufficient refrigerant cannot absorb enough heat from outdoor air. We locate and repair the leak before recharging the system to factory specifications.
- Failed defrost board - In cold weather, a malfunctioning defrost cycle allows excessive ice buildup on the outdoor coil, dramatically reducing heating capacity.
- Faulty auxiliary heat strips - If your backup heat strips have burned out or their relays have failed, your system may struggle during the coldest periods.
During East Texas summers - when temperatures regularly exceed 95 degrees with high humidity - a heat pump that cannot cool your home needs immediate attention:
- Compressor failure - The compressor circulates refrigerant through the system. When it fails, neither heating nor cooling is possible. We diagnose whether a compressor repair or replacement is the most practical solution.
- Dirty or blocked outdoor coil - Debris, dirt, and vegetation around the outdoor unit restrict airflow across the condenser coil, reducing cooling capacity significantly.
- Malfunctioning metering device - An improperly functioning expansion valve or piston causes incorrect refrigerant flow, leading to poor cooling performance, ice formation, or compressor strain.
- Electrical control failures - Capacitors, contactors, and relays can fail due to sustained high temperatures, preventing the outdoor unit from starting or running properly.
If your heat pump never seems to shut off, it may be struggling to reach the set temperature due to:
- Undersized system - While we cannot resize your existing equipment during a repair visit, we can identify whether your system's capacity matches your home's cooling and heating load and recommend appropriate next steps.
- Refrigerant issues - A system that is low on refrigerant works harder and longer to achieve the same temperature. Our technicians perform precise refrigerant measurements and compare them to manufacturer specifications.
- Ductwork leaks - Conditioned air escaping through leaky ductwork forces your heat pump to run longer cycles. We can identify significant duct leaks during our diagnostic process.
- Thermostat problems - A miscalibrated or malfunctioning thermostat may not communicate the correct temperature readings to your heat pump, causing continuous operation.
Different sounds point to different problems, and our team has heard them all over four decades of service:
- Grinding or screeching - Usually indicates a failing motor bearing in the compressor, fan motor, or blower motor. This needs prompt attention to prevent complete motor failure.
- Clicking at startup - Repeated clicking without the unit starting often points to a failed capacitor or contactor.
- Whooshing or hissing during mode changes - Some refrigerant noise during the reversing valve operation is normal, but loud or prolonged hissing may indicate a refrigerant leak.
- Rattling or banging - Loose mounting hardware, a damaged fan blade, or debris inside the outdoor unit can produce these sounds.
If your heat pump is making any noise that seems out of the ordinary, book a diagnostic appointment before a minor issue becomes a major repair.
Our Approach
Our Diagnostic Approach to Heat Pump Repair
At 903 HVAC, we do not replace parts based on guesswork. Our diagnostic process is systematic and thorough, drawing on over 40 years of experience working on heat pump systems in the East Texas climate. Here is how we approach a heat pump repair call:
Electrical System Check
We start by verifying that your heat pump is receiving proper voltage and that all electrical connections are secure. We test capacitors, contactors, relays, and control boards with professional-grade meters. Electrical issues are among the most common failure points we see in Tyler and the surrounding areas due to the high temperatures and occasional storms our region experiences.
Refrigerant System Evaluation
Proper refrigerant charge is essential for heat pump performance in both heating and cooling modes. We measure superheat, subcooling, and pressures at the service ports and compare readings against American Standard specifications for your specific model. If the charge is off, we determine whether a leak exists, locate it, and make the proper repair before recharging the system.
Airflow Assessment
Restricted airflow through the indoor coil or outdoor coil degrades performance and can cause secondary damage. We check air filters, evaporator coil condition, blower motor operation, and outdoor unit clearance. In East Texas, allergens, pollen, and humidity can cause indoor coils to accumulate biological growth that restricts airflow - something our technicians are very familiar with identifying and addressing.
Thermostat and Controls
We verify that your thermostat is calibrated correctly, communicating properly with the heat pump, and cycling the system through the correct stages. We also check that the reversing valve energizes in the correct mode and that the defrost cycle initiates and terminates properly.
This methodical approach saves you money by ensuring we repair the actual problem - not just the most obvious symptom.

Frequently Asked Questions About Ducted Heat Pump Repair
Generally, if your heat pump is less than 10-12 years old and the repair cost is reasonable relative to the system's value, repair is usually the better option. If your system is older, requires frequent repairs, or the compressor has failed, replacement may make more financial sense. Our technicians at 903 HVAC will give you an honest assessment and help you weigh the costs and benefits of each option - we do not push replacements when a repair will serve you well.
Several things can cause this. The most common culprits are a stuck reversing valve, low refrigerant charge, or a malfunctioning defrost cycle. It is also possible that your auxiliary heat strips have failed, leaving only the heat pump to do all the work on very cold days. Our technicians will systematically check each potential cause to find and fix the actual problem.
Heat pumps share many components with standard air conditioners, but they also have unique parts - like the reversing valve, defrost controls, and dual metering devices - that require specific training to diagnose and repair properly. At 903 HVAC, our technicians are specifically trained on heat pump systems, including American Standard models, and have decades of experience working on these systems in East Texas conditions.
Because heat pumps run year-round in both heating and cooling modes, we recommend professional maintenance at least twice a year - once before cooling season and once before heating season. Our Essential Comfort Plan covers these seasonal tune-ups and helps prevent the kind of unexpected breakdowns that lead to emergency repair calls.
A thin layer of frost on the outdoor coil during heating mode is normal - your heat pump's defrost cycle should melt it periodically. However, thick ice buildup indicates a problem with the defrost control board, defrost sensor, or timer. It can also be caused by low refrigerant, a stuck reversing valve, or a blocked outdoor coil. Thick ice should be addressed promptly to prevent damage to the outdoor unit.
Yes, a brief whooshing or hissing sound when your heat pump switches between heating and cooling (or during defrost cycles) is normal. It is the sound of the reversing valve redirecting refrigerant flow. However, if the sound is very loud, prolonged, or accompanied by poor performance, it could indicate a problem with the reversing valve or a refrigerant leak, and you should have it inspected.
Most common heat pump repairs - such as replacing a capacitor, contactor, fan motor, or defrost board - can be completed in one to two hours. More complex repairs involving the compressor, reversing valve, or refrigerant system may take longer. Our technicians arrive with commonly needed parts to minimize the number of visits required.
We understand that losing both heating and cooling at the same time is a serious concern, especially during extreme weather. We work to accommodate urgent repair needs as quickly as possible. Call us at 903-393-1044 to discuss your situation, and we will do our best to get a technician to your home promptly.
