Our Package Unit Maintenance Service Process
Appointment Scheduling & System History Review
When you contact us to schedule maintenance, we’ll recommend ideal timing: spring (March–May) for pre-cooling-season prep, or fall (September–November) for post-summer assessment. If you’re on our maintenance plan, we’ll review your prior visit history to track trends and spot developing issues.
We’ll confirm your system configuration (rooftop or ground-level unit), location and accessibility, any known issues, and questions you have about operation. Our technician will arrive fully equipped with tools, refrigerant gauges, furnace inspection equipment, and replacement filters so we can complete the full service without delays.
Key steps in this phase
- Scheduling recommendation based on ideal seasonal timing (spring/fall)
- Review of prior maintenance history and developing trends
- Discussion of system configuration and any concerns you’ve noticed
- Confirmation of unit access and location
- Preparation of service truck with all maintenance tools and supplies
Visual Inspection of All System Sections
Our technician performs a comprehensive visual inspection. For the cooling section, we check: condenser coil cleanliness, fan operation, vibration isolation, refrigerant line condition, and visible corrosion or damage. For the furnace section, we check: burner condition, heat exchanger appearance, air intake cleanliness, gas line connections, and exhaust vent routing.
We also inspect electrical connections, capacitors, contactor relays, blower motor condition, and the condensate drainage system. This initial visual assessment takes 15–20 minutes and often reveals simple maintenance needs: debris blocking condenser airflow, a clogged condensate drain, or loose connections requiring tightening.
Key steps in this phase
- Cooling section inspection: condenser coil, fan, refrigerant lines, vibration mounts
- Furnace section inspection: burners, heat exchanger, air intake, gas connections
- Electrical component inspection: capacitors, contactors, motor condition
- Condensate drainage path verification
- Blower motor operation and bearing assessment
- Documentation of all visible conditions
Refrigerant System Testing & Cooling Performance Verification
Using specialized gauges, we measure refrigerant pressure on both high and low sides. Proper pressure is essential for cooling efficiency and system longevity. If pressure is low, it indicates a slow leak — often undetectable by the homeowner but reducing efficiency by 10–20%. Catching leaks during maintenance prevents summer performance loss and protects your compressor.
We inspect refrigerant line connections for oily residue (a leak indicator) and check line insulation condition. We also measure coil temperatures and compare them to specifications. We verify the condenser fan is operating and that outdoor airflow is unrestricted. All data is documented to create a baseline for comparison on future visits.
Key steps in this phase
- High-side pressure gauge connection and reading
- Low-side pressure gauge connection and reading
- Comparison against Trane specifications for your system capacity
- Visual inspection of all refrigerant connections for oily residue
- Refrigerant line insulation condition assessment
- Condenser coil temperature measurement
- Condenser fan operation and airflow verification
- Documentation of all pressure and temperature data
Furnace Section Testing & Gas System Verification
We verify that your furnace is ready for heating season (spring maintenance) or performing properly after heavy summer demand (fall maintenance). We check gas pressure at the unit, verify the ignition sequence operates correctly, inspect burner condition, check heat exchanger for visible cracks or damage, and verify the furnace exhaust vent is clear.
We also test the gas valve response to thermostat signal, verify safety controls operate, and check that the furnace produces heat efficiently. If your system is electric-resistance heating instead of gas furnace, we test electrical heating element operation. All furnace testing is documented.
Key steps in this phase
- Visual inspection of burner condition and flame color
- Gas pressure verification at the unit
- Ignition sequence testing and control signal verification
- Heat exchanger inspection for cracks or rust
- Furnace draft and exhaust vent verification
- Safety control testing (rollout switch, limit switch)
- Thermostat-to-furnace signal verification
- Documentation of all furnace performance data
Filter Replacement & Coil Cleaning
We replace your system’s air filter (or clean it if reusable) and clean coil surfaces to restore cooling and heating efficiency. A clogged filter forces your system to work harder, reduces airflow, and increases energy bills. In Florida, filters often need replacement every 2–4 weeks during heavy cooling use.
We clean the condenser coil (outdoor section) using appropriate cleaning solutions and soft brushing, removing leaves, pollen, and dust accumulation that blocks airflow. We also inspect and clean the evaporator coil surface (indoor section) if accessible. A clean coil ensures maximum heat transfer efficiency and prevents the coil freeze-up that can occur with dust-covered surfaces.
Key steps in this phase
- Air filter replacement (disposable) or cleaning (reusable)
- Careful handling to maintain filter seal integrity
- Condenser coil cleaning with approved solutions and soft brush
- Evaporator coil inspection and surface cleaning
- Verification of proper airflow after cleaning
- Filter access and replacement schedule review
Electrical System Testing & Control Signal Verification
We test electrical safety on the main disconnect, verify capacitor condition (capacitors are frequent failure points in Florida heat), test compressor amp draw under operation, and measure voltage at key system points. We also verify that all control signals — thermostat to furnace, furnace to blower, cooling to heating sequencing — are communicating properly.
We test the thermostat for proper operation, check battery condition, verify display clarity, and confirm temperature sensing accuracy. Any loose or corroded connections are tightened and documented. This electrical testing is comprehensive because integration between heating and cooling controls is critical in a package unit.
Key steps in this phase
- Outdoor disconnect electrical safety inspection
- Capacitor condition testing (visual and electrical)
- Compressor amp draw measurement under operation
- All control signal verification (thermostat, furnace, blower sequencing)
- Voltage verification at key system points
- Thermostat functionality testing and battery condition check
- Any loose or corroded connections tightened
- Documentation of all electrical readings
System Operation Test & Performance Documentation
We run your system in both heating and cooling modes (if applicable), monitoring pressures, temperatures, and operation. In cooling mode, we verify that the condenser operates, the compressor runs, and cold air flows properly. In heating mode, we verify that the furnace ignites, burners operate, and warm air is delivered. We listen for unusual noises and check that the system operates quietly after cleaning.
We document all operating pressures, temperatures, electrical amperage, and performance metrics. This data becomes a baseline — on your next visit, we can compare measurements to spot any developing trends. We also verify that condensate is draining properly without backups.
Key steps in this phase
- System startup in cooling mode with performance verification
- Pressure and temperature measurement during cooling operation
- System startup in heating mode (if applicable) and operation verification
- Noise assessment — any grinding, hissing, or squealing?
- Condensate drainage test and verification
- Thermostat response and control signal verification
- Documentation of all readings and operating metrics
Written Findings Report & Recommendations
Before we leave, we provide a detailed written report. It includes refrigerant pressures, electrical test results, furnace performance data, filter and coil condition notes, any issues found (and severity), and recommendations for your next visit. This transparency is critical — you’ll know exactly what your system’s status is and can plan for repairs or replacements.
We’ll also discuss our findings verbally, answer questions, and explain what maintenance is preventing and why it matters. If we found a slow refrigerant leak, we’ll discuss whether it’s urgent or can be addressed at your next visit. If a component is showing age, we’ll discuss replacement timing and costs. And we’ll emphasize how maintenance plan enrollment protects your investment and reduces emergency repair risk.
Key steps in this phase
- Detailed written findings report with all test results and observations
- Verbal discussion of findings and recommendations
- Explanation of what maintenance prevented and why it matters
- Discussion of any repairs needed and timeline
- Maintenance plan enrollment information
- Scheduling recommendation for your next maintenance visit

Florida’s warm, humid climate produces dust and pollen year-round. Package unit filters are compact and can clog quickly. During heavy cooling season (May–September), filters often need replacement every 2–4 weeks. Regular replacement maintains efficiency and indoor air quality.
You can replace filters yourself. However, professional maintenance includes refrigerant testing, furnace diagnostics, electrical safety testing, and coil cleaning that require specialized training and tools. Professional maintenance catches problems DIY cleaning misses.
Small problems can compound. A slow refrigerant leak can continue undetected, coils can accumulate dust that forces the system to work harder, and furnace components can corrode. Left unaddressed, these issues can lead to an expensive emergency repair — a compressor failure or furnace failure. Regularly scheduled maintenance helps catch these issues early.
