Responded to service call for 3-month-old air conditioning unit running continuously without cycling off. Upon inspection, identified malfunctioning printed circuit board (PCB) preventing proper thermostat communication and system shutdown. Customer had been manually turning off unit at breaker to stop operation. Documented attic installation and basement mechanical areas, noting system configuration and wiring paths. Assessed control board failure as primary cause of continuous operation issue and provided recommendations for PCB replacement to restore normal cycling function.

Responded to service call for ceiling fan installation assistance. Upon arrival, found that existing electrical wiring had deteriorated and crumbled during customer's attempted DIY ceiling fan replacement. Assessed the damaged wiring condition and documented the electrical hazard for proper repair recommendations.

Responded to service call for gas line assessment prior to dryer installation. Previous installation attempt by third-party appliance installer was halted due to concerns about shutting off gas supply to the residence. Performed comprehensive inspection of existing natural gas piping system in crawlspace and attic areas, examining gas line routing, connections, and shutoff valve accessibility. Verified proper gas line sizing and configuration for dryer connection. Documented existing copper gas piping, support strapping, and connection points throughout the mechanical spaces. Confirmed gas system integrity and provided clearance for appliance installation to proceed safely.

Installation failed initial inspection due to code violations. The outdoor condensing unit was positioned too close to the electric meter, blocking the required 36-inch minimum clearance for safe working space around electrical equipment. Additionally, refrigerant lines in the basement lacked proper support, missing at least one required bracket to secure the line set per installation standards. Job is on hold pending manager approval for corrective action plan to relocate equipment and install proper line support hardware.

Completed MVP cooling maintenance visit on residential Lennox HVAC system. Performed standard preventive maintenance procedures on outdoor condensing unit including coil washing as requested. Inspected indoor furnace unit and associated components in basement mechanical room. System operational and functioning within normal parameters upon completion of service visit.

Completed MVP cooling maintenance visit on Lennox EL16XC1 heat pump system containing HFC-410A refrigerant. Performed standard preventive maintenance inspection and documented heavily contaminated outdoor unit coil and filter requiring immediate cleaning due to excessive dirt, debris, and organic material accumulation that could restrict airflow and reduce system efficiency.

Responded to no cooling complaint on HVAC system. Upon inspection, diagnosed failed capacitor preventing compressor and condenser fan operation. Replaced defective dual run capacitor with proper OEM replacement, verified all electrical connections secure, and tested system operation.
