Heat Pump Maintenance Experts
Professional Ducted Heat Pump Maintenance in Plano, TX
Your ducted heat pump does double duty - cooling your home through the relentless North Texas summer heat and warming it during the unpredictable winter months. That year-round workload puts more hours on a heat pump than on any standalone heating or cooling system in your home. Without routine professional maintenance, those accumulated hours translate into declining efficiency, higher utility bills, and a significantly shorter equipment lifespan.
Trotter Air Services has been maintaining HVAC systems for families across Plano, TX and the Greater Dallas area since 1970. We are a family-owned company - three generations deep - and our approach to heat pump maintenance reflects decades of hands-on field knowledge. As an Armstrong ProTeam dealer, we understand the specific maintenance needs of these systems at a manufacturer-certified level.

Why Ducted Heat Pump Maintenance Is Not Optional in North Texas
Every HVAC manufacturer recommends professional maintenance at least once per year. For ducted heat pumps in North Texas, we recommend service twice per year - once before cooling season begins and once before heating season. The reason is straightforward: your heat pump runs in both modes, and each mode stresses different components in different ways.
Here is what happens when maintenance gets skipped:
- Efficiency drops measurably. A heat pump that has not been professionally serviced in two or more years can lose 10 to 25 percent of its original efficiency. Dirty coils, clogged filters, and degraded electrical connections all force the system to work harder to produce the same output.
- Component failures accelerate. Electrical connections loosen over time from thermal cycling - repeated heating and cooling of the conductors. Capacitors degrade. Contactors pit and burn. Refrigerant leaks start small and grow. Without regular inspections, these issues progress until they cause a complete system failure, usually during the most extreme weather when your heat pump is working the hardest.
- Equipment lifespan shortens. A well-maintained heat pump in North Texas can last 15 to 20 years. A neglected one often fails between 8 and 12 years. Given the investment a heat pump represents, the math on maintenance pays for itself many times over.
- Warranty coverage may lapse. Most Armstrong warranties require proof of regular professional maintenance. If a major component fails under warranty and the manufacturer finds no record of routine service, your claim could be denied.
Professional maintenance is not about finding problems to sell you repairs. It is about preventing problems from developing in the first place. That distinction matters, and at Trotter Air Services, we have built our reputation on honoring it.
What Our Ducted Heat Pump Maintenance Service Includes
Our heat pump maintenance service is thorough, methodical, and designed to catch problems while they are still small. Here is a detailed look at every step of the process.
Thermostat Calibration and Control Verification
We start at your thermostat. Heat pump thermostats manage more functions than standard AC thermostats - they control the reversing valve, auxiliary heat lockout, and emergency heat staging in addition to normal temperature regulation. We verify that your thermostat is reading temperatures accurately, switching modes correctly, and communicating properly with every component in your system.
Electrical System Inspection
Electrical issues are the leading cause of heat pump failures. During every maintenance visit, our NATE-certified technicians tighten all electrical connections, measure voltage and amperage, test capacitors and contactors, inspect control boards, verify reversing valve operation, and ensure all electrical work meets code requirements.
Refrigerant System Evaluation
Your heat pump's refrigerant charge must fall within a precise range for the system to operate efficiently in both heating and cooling modes. We measure superheat and subcooling at the appropriate points to confirm the charge is correct. If the readings are off, we check for leaks before adding refrigerant - topping off a leaking system without finding the leak is a temporary fix that wastes refrigerant and your money.
Coil Cleaning and Inspection
Both the indoor evaporator coil and the outdoor condenser coil must be clean for your heat pump to transfer heat effectively. We inspect and clean both coils as needed, removing debris from the outdoor unit and checking the indoor coil for dust buildup, mold growth, and drainage issues.
Condensate Drain Maintenance
Your heat pump produces condensation - primarily during cooling mode but also during the defrost cycle in heating mode. The condensate drain line must remain clear to prevent water damage to your home and humidity problems. We flush the drain line, clear any developing blockages, and confirm that water flows freely from the system.
Condensation and moisture management directly affect your indoor air quality. If your home feels humid even when the AC is running, or if you have noticed musty odors near your vents, our humidifier and dehumidification services can provide whole-home moisture control that works alongside your heat pump for balanced comfort.
Defrost System Testing
The defrost system is unique to heat pumps and essential for winter operation. During heating mode, moisture from the outdoor air can freeze on the outdoor coil. Your heat pump's defrost controls monitor coil temperature and initiate a brief reversal to cooling mode to melt the ice. We test the defrost control board, the outdoor temperature sensor, and the defrost timer or demand-defrost controls to verify they will respond correctly when cold weather arrives.
Airflow Optimization
Proper airflow through your ductwork is fundamental to heat pump performance. We replace or clean the air filter, check blower motor operation, inspect accessible ductwork for leaks, verify that registers are open and unobstructed, and measure static pressure to assess overall duct system performance.
The filter you choose affects both your heat pump's performance and the air your family breathes. If anyone in your household deals with allergies, asthma, or respiratory sensitivities, our air filtration and air cleaner services can help you select a filtration solution that protects both your equipment and your health.
Outdoor Unit Inspection
The outdoor unit takes a beating in North Texas. We inspect fan blade condition and clearance, fan motor bearings and operation, compressor sound and vibration, base pan and mounting hardware, wiring insulation and conduit integrity, physical condition of the cabinet and coil fins, and clearance around the unit - we recommend at least 24 inches of clear space on all sides for adequate airflow.
Performance Documentation
After completing all maintenance procedures, we document our findings, record key measurements, and provide you with a written summary of your system's condition. If we identify anything that needs attention - now or in the near future - we explain the issue clearly and give you an honest recommendation. No pressure, no scare tactics, just straightforward information so you can make informed decisions.

Frequently Asked Questions About Ducted Heat Pump Maintenance in Plano, TX
We recommend twice-yearly maintenance for ducted heat pumps in North Texas - once in the spring before cooling season and once in the fall before heating season. Because heat pumps operate year-round in both heating and cooling modes, they benefit from service before each major season. This is more frequent than the once-per-year recommendation for standalone air conditioners or furnaces, and it reflects the additional workload that a heat pump handles.
A complete maintenance visit includes thermostat calibration, electrical connection inspection and tightening, capacitor and contactor testing, refrigerant charge evaluation, indoor and outdoor coil cleaning, condensate drain flushing, defrost system testing, airflow assessment, blower motor inspection, and a comprehensive outdoor unit evaluation. Our NATE-certified technicians document all findings and measurements.
You can and should handle basic tasks between professional visits - replacing or cleaning your air filter monthly, keeping the area around your outdoor unit clear of debris, and visually inspecting the unit for obvious issues. However, the critical components of heat pump maintenance - electrical testing, refrigerant evaluation, defrost system verification, and detailed component inspection - require professional tools, training, and certification. Attempting these tasks without proper expertise can damage your system or create safety hazards.
Absolutely. A well-maintained ducted heat pump in North Texas typically lasts 15 to 20 years, while a neglected system may fail between 8 and 12 years. Regular maintenance catches developing issues before they cascade into major failures, keeps electrical connections tight, ensures refrigerant levels are correct, and maintains the clean coils and proper airflow that reduce strain on the compressor - the most expensive component in your system.
Most Armstrong heat pump warranties include a maintenance requirement. The manufacturer expects regular professional service, and failing to maintain documented proof of maintenance can jeopardize your warranty coverage on major components like the compressor. Our service records are designed to meet manufacturer documentation standards.
A maintenance plan with Trotter Air Services includes scheduled service visits - typically spring and fall for heat pumps - along with priority scheduling, documented service history, and professional system monitoring over time. A one-time service call is a single visit without the ongoing relationship and scheduling benefits. Maintenance plan members go to the front of the line during peak seasons, which in North Texas can mean the difference between same-day service and a multi-day wait.
The ideal windows are March through April for pre-cooling-season service and September through October for pre-heating-season service. These periods allow us to prepare your system before the extreme weather hits, and our schedule is typically more flexible during these shoulder seasons than during the peak summer and winter months.
Maintenance is primarily preventive - its purpose is to prevent problems from developing. However, our thorough inspection process often identifies issues that are in their early stages, before they cause a noticeable problem. If we find something during maintenance that needs repair, we explain the issue, provide a recommendation, and can often address it during the same visit.
For existing performance issues, unusual noises, or system malfunctions, our ducted heat pump repair services provide focused diagnostics and resolution. Maintenance and repair work together - regular maintenance reduces repair frequency, and prompt repair when issues arise prevents collateral damage to other components.
Yes. While our deepest manufacturer-specific expertise is with Armstrong systems - due to our ProTeam dealer relationship - our NATE-certified technicians are trained and experienced in maintaining all major brands of ducted heat pumps. The fundamental maintenance procedures apply across brands, and our systematic approach ensures thorough service regardless of manufacturer.
Yes, we partner with Service Finance to provide flexible financing options for heat pump repairs, replacements, and related services. We discuss options during your visit so you can choose what works best for your budget.
