Package Unit Maintenance & Tune-Up in Papillion, NE

You call or book online to schedule your maintenance—typically spring (April–May) before cooling season or fall (September–October) before heating season. We ask a few quick questions about your system's age, recent performance, and any concerns so we arrive fully prepared. Plan members receive priority scheduling.

• We're available Monday–Friday 8 AM–5 PM and Saturday 8 AM–12 PM
• Maintenance plan members receive priority appointment scheduling
• We book tune-ups ahead of peak heating and cooling seasons
• Seasonal peaks (March–May, September–October) may require longer lead times

The technician starts with a full walk-around: examining the outdoor cabinet for corrosion or damage, checking airflow around the unit, inspecting refrigerant lines for leaks or damage, and testing that the unit is properly grounded and all electrical connections are tight. This foundational inspection catches problems before they escalate and identifies maintenance issues specific to your unit's age and operating environment.

• We look for signs of past leaks, rust, or wear on the cabinet and frame
• We check that outdoor fans spin freely, without vibration or grinding
• We verify no visible damage to copper refrigerant lines or connection fittings
• We ensure the cabinet is clean, clear of leaves and debris, and drainage is flowing
• We inspect mounting brackets and vibration dampeners for looseness or deterioration
• We look for any signs of rodent nesting or pest damage to wiring or insulation

Using calibrated digital gauges, we measure the refrigerant pressure in both the suction and discharge lines. Proper readings confirm the system is charged correctly; low pressure indicates a leak, and high pressure may signal a blockage or airflow problem.

• We measure both high-side and low-side pressures to assess system health
• We compare readings to the manufacturer's specifications for your unit
• Low pressure triggers a refrigerant leak search using electronic detection
• We document all readings in your maintenance report

We test thermostat responsiveness, check contactor operation, inspect capacitors for swelling or corrosion, and verify that all controls respond properly. A failing capacitor can be replaced before it damages the compressor, and proper electrical testing ensures your system will operate safely and predictably. Electrical problems are often early warning signs of larger issues, so this step is critical to preventing mid-season failures.

• We test the thermostat in heating and cooling modes, checking response time
• We check for loose electrical connections on the board and at all terminals
• We visually inspect capacitors for swelling, leaks, or burn marks
• We run voltage and continuity tests on capacitors to verify operation
• We verify fan and compressor response to thermostat signals
• We check breaker operation and ensure no tripped or loose switches
• We inspect the control board for corrosion, burn marks, or water damage

Dirty coils reduce heat transfer and force your system to run longer, raising energy use. We clean the outdoor coil (condenser) and check indoor airflow over the evaporator. If the return air is restricted, we identify the cause.

• We clean outdoor coils with specialized coil cleaner and a soft brush
• We check indoor filter condition and airflow
• We look for blockages in return ducts or vents
• We measure temperature differential to verify heat exchange

Moving parts benefit from proper lubrication. We lubricate fan motors and other moving parts where applicable, inspect belts for cracks, and check all fasteners for tightness. Loose hardware can vibrate loose further and cause noise, increasing wear on components. This step helps reduce operating noise and prevents premature bearing wear that could lead to motor failure.

• We lubricate motors and bearings per manufacturer specification
• We check and tighten all visible bolts and fasteners, including cabinet screws
• We inspect rubber vibration dampeners for wear, cracking, or deterioration
• We look for any signs of rubbing, wear marks, or component misalignment
• We verify that all fittings are secure and won't rattle during operation
• We inspect the fan blade for damage or imbalance that could cause vibration

Before leaving, we give you a detailed maintenance report: what we inspected, what's in good condition, what small issues we found (and recommended addressing before they become big ones), and what major problems (if any) need attention. You get a copy for your records.

• The report documents all test results and findings
• We explain any issues in plain language, not jargon
• We recommend repairs if we find anything unsafe or worn
• We tell you honestly what can wait versus what needs attention now
