Package Unit Maintenance in Greers Ferry, AR

Pre-Visit Planning & Seasonal Assessment

We confirm the time that works best for your schedule and gather information about your unit: age, last service date, any performance concerns, and whether it's been heating, cooling, or idle recently. We review your system's maintenance history and note past repairs or recurring issues. We check Greers Ferry's current weather and forecast to understand seasonal conditions, prepare a detailed checklist specific to your unit's age and brand (Ruud, Daikin, American Standard), confirm the visit time the day before, and arrive with all necessary tools, cleaning supplies, and diagnostic equipment in one trip.

External Inspection & Condenser Coil Assessment

Our technician arrives at your rooftop safely and conducts a complete visual inspection of the exterior: checking mounting bolts, inspecting the condenser coil for blockages and corrosion, verifying condenser fan operation, and assessing structural integrity. We examine the coil for dust, pollen, mineral scaling, and physical damage, then perform coil cleaning using industry-appropriate methods. We verify the condensate drain line is clear and properly sloped, inspect all refrigerant lines for visible leaks, and check the unit's protective cover isn't restricting airflow.

Electrical & Safety Control Verification

We perform a comprehensive electrical inspection: checking the disconnect switch, verifying connections are tight and insulated, testing voltage at the compressor against the nameplate rating, and confirming amperage draw is within design range. We test all safety controls—high-pressure and low-pressure shutoff switches and thermal overload protection. We check capacitor voltage and condition, verify thermostat communication, and document all electrical readings in writing so you have a baseline for future comparisons.

Refrigerant Charge Verification & Adjustment

We measure suction and discharge refrigerant pressures and compare them to design specifications for your unit's current ambient temperature. We calculate superheat and subcooling to confirm the refrigerant is boiling and condensing correctly. If charge is low, we perform a detailed leak check with electronic detection equipment, trace the leak to its source, and flag it for repair—simply adding refrigerant without fixing the leak is temporary. If charge is correct, we document it in writing and explain what the readings mean.

Blower & Airflow Assessment

We verify the indoor blower is running smoothly and quietly—grinding or squealing indicates bearing wear and potential motor failure. We check the evaporator coil for cleanliness and proper drainage, measure airflow across the condenser and compare it to design specifications, and test the blower motor capacitor. We verify thermostat fan settings and ensure the blower is cycling correctly with system operation.

System Testing & Performance Baseline

We run the system through a complete heating or cooling cycle and measure performance: supply air temperature, return air temperature, temperature differential, and comparison to design specifications. We confirm the system cycles smoothly without short-cycling or hunting, test thermostat response, and perform a pressure drop test across the filter. We create a written performance record documenting baseline temperatures, pressures, and efficiency metrics so future visits can track performance drift.

Documentation, Recommendations & Scheduling Next Service

We provide a detailed written report documenting all findings, measurements, maintenance performed, and recommendations. If we identify problems needing attention, we explain the urgency and cost so you can decide. We discuss seasonal considerations for the next few months, recommend scheduling your next visit for the opposite season, and share information about our maintenance plan membership. We leave you with our direct contact number and explain what constitutes an emergency.
