WHAT A MAINTENANCE INCLUDES
The whole system gets checked.
A PMA visit is more than a quick look and a filter reminder. We check system operation, airflow, electrical components, safeties and the equipment-specific items that matter for the season. Items are performed as applicable to your system.
Airflow & system performance
Measure return and supply static pressure, verify total external static pressure, check temperature rise or cooling temperature split, inspect blower operation, verify airflow, and note duct or restriction concerns.
Thermostat & controls
Verify thermostat operation, system mode, setpoints, staging and control response. Check accessible low-voltage wiring and confirm the equipment starts, runs and shuts down correctly.
Electrical inspection
Check line voltage, inspect disconnects and accessible wiring, tighten accessible electrical connections, inspect contactors and relays, test capacitors, and measure motor/compressor amp draw where applicable.
Indoor equipment & evaporator coil
Inspect the blower assembly, cabinet, insulation, filter condition and fit, and accessible duct connections. Clean the evaporator coil as needed and accessible, and check for moisture, dirt, overheating, biological buildup or abnormal wear.
Condensate & drain protection
Inspect primary and secondary drains, clear or flush accessible drain lines as needed, check condensate pump operation where present, and test accessible float switches and overflow safeties.
Outdoor equipment & condenser coil
Clean the condenser coil, inspect the fan motor and blade, cabinet, electrical compartment, contactor and capacitor, refrigerant-line insulation, vibration, debris and overall operating condition.
Refrigerant-side checks
Check operating pressures and temperatures when conditions allow, evaluate superheat/subcooling as applicable, inspect accessible refrigerant piping, and look for signs of oil, leaks, icing or abnormal system operation.
Gas furnace, heat exchanger & combustion safety
Inspect and clean burners, verify ignition sequence and gas valve operation, inspect accessible gas connections, measure temperature rise, and check venting and flue condition. Clean the heat exchanger as accessible and inspect it with a camera for cracks, deterioration or other visible defects. Perform carbon monoxide testing in the home, at supply vents and at the flue, and verify applicable furnace safeties.
Heat pump & electric heat
Verify heating operation, auxiliary/emergency heat where equipped, defrost operation when conditions allow, reversing-valve response, heat-strip amp draw and related safeties as applicable.
Safety controls
Verify accessible limits, pressure switches, float switches, rollout/overheat protection and other equipment safeties appropriate to the system. We also note visible concerns involving venting, combustion or electrical safety.
Cleaning & condition check
Clean accessible coils and equipment surfaces, remove normal accessible debris, check drain pans and cabinet condition, and identify buildup, corrosion, overheating, biological growth or repair needs before they become larger problems.
Documented in your customer portal
We save the maintenance findings to your AllTemp customer portal so you have a clear service record to reference later. Documentation can include equipment data plates, before-and-after photos, gauge readings, inspection-camera photos, videos when applicable, key measurements, system-condition notes, safety concerns and recommended repairs.
