# HVAC Cooling Maintenance Service Completed Performed comprehensive cooling maintenance on two 9-year-old air conditioning systems. Service included complete system inspection, performance testing, and verification of proper operation on both units. ## Work Performed Conducted thorough visual inspection of outdoor condensing units. Noted accumulated dirt and grime on exterior coil fins and cabinet surfaces. Cleaned condenser coils to restore optimal heat transfer efficiency and airflow. Removed debris and vegetation growth from around unit base and concrete pad perimeter. Inspected and serviced electrical components including motor assemblies and service valves mounted on unit. Verified proper electrical connections and conduit routing along building exterior. Tested capacitor performance and amp draw on both systems. Replaced air filtration media on both systems. Removed old pleated filters showing dirt accumulation and installed new high-efficiency pleated filters with cardboar

Completed comprehensive tune-up on a 10-year-old residential air conditioning unit located in backyard. Performed standard maintenance protocol including electrical diagnostics using digital multimeter, recording voltage readings of 33.32V and 11.13V at various system points to verify proper electrical operation and component functionality. All measurements fell within acceptable parameters, system operating efficiently with no issues identified.

Returned to new installation site to complete system charging. Connected refrigerant manifold gauges and verified system pressures, recording 113 PSIG suction pressure with 16.8°F superheat and 30.34 PSIG liquid line pressure with 18.3°F subcooling, confirming proper refrigerant charge and optimal system operation.

Responded to service call for clogged bathroom sink on second floor hallway bathroom. Upon arrival, assessed the pedestal sink and determined blockage in drain line. Removed obstruction from drain assembly using appropriate plumbing tools. Tested water flow and drainage to confirm proper operation. Inspected visible plumbing connections beneath sink to ensure no leaks or additional issues. Left fixture in full working order with clear drainage.

Responded to recall for recurring main sewer line backup in 70-year-old home following previous snaking attempt. Upon investigation, performed video camera inspection of main line and discovered severe root intrusion causing blockage. Extracted substantial root mass from cleanout access point, documenting condition with photographs showing extensive root penetration into pipe system. The root accumulation indicated compromised pipe integrity consistent with age of cast iron or clay sewer lines typical of home's construction era. Cleared accessible root mass and advised property owner that permanent resolution would require excavation and replacement of affected pipe section, as recurring blockages will continue due to structural damage allowing root entry.

Responded to reported gas leak at 5-year-old furnace where gas utility had shut off supply valve as safety precaution. Upon arrival, performed comprehensive inspection of gas train components and identified corroded union connection at gas valve inlet showing visible green oxidation and deterioration. Conducted leak detection testing which confirmed active gas leak at the compromised union fitting. Replaced defective union connection, pressure tested entire gas line assembly to manufacturer specifications, and verified all connections were secure with no detectable leaks. Restored gas supply and performed complete system startup, confirming proper ignition sequence, burner operation, and flame characteristics within normal parameters.

# Plumbing Service - Ground Water Drain Responded to basement drainage issue where water was actively discharging from floor drain. Upon investigation, determined the problem was directly correlated with HVAC system operation—water level would rise when air conditioning unit was running and recede when system was shut off. Diagnosed the issue as a condensate drain line improperly connected to or overwhelming the basement floor drain system. Cleared debris and obstructions from the affected drain using appropriate plumbing tools. Inspected condensate drainage pathway and verified proper flow away from the floor drain. Tested system by running the air conditioning unit and confirmed water was no longer backing up through the basement drain. Floor showed evidence of previous water infiltration and staining, consistent with recurring drainage issues prior to service.

Completed cooling tune-up on 13-year-old outdoor unit, performing standard maintenance procedures including system inspection, temperature verification at thermostat reading 78°F, and filter assessment. Observed heavily soiled air filter with significant dust and debris accumulation, which was documented for replacement recommendation to ensure optimal airflow and system efficiency.
