Completed scheduled maintenance on 9-year-old geothermal cooling system. Inspected electrical connections at control panel, verified proper wire terminations at contactor terminals T1/T2 and L1/L2, and examined air handler blower motor assembly rated at 14.4/19.2 AMP, 208/240V, 1500 CFM. All components operating within manufacturer specifications with no deficiencies noted.

Responded to service call for 9-year-old Rheem heat pump system with reported leaking concerns. Upon inspection, discovered significant rust and corrosion on internal burner assembly and gas manifold components, with visible rust staining on interior metal surfaces beneath the affected areas. Documented existing condition through photographs showing deteriorated cylindrical burner component with brass valve stems and orange-brown rust discoloration throughout the combustion chamber area. Advised customer of findings and potential need for follow-up service to address corrosion issues and prevent further system degradation.

Conducted comprehensive on-site estimate for geothermal HVAC system installation. Evaluated existing mechanical room space containing QT-EA unit with multiple refrigerant lines and documented current equipment configuration, including connection points and spatial constraints. Assessed basement utility area with wooden framework structure to determine feasibility and requirements for geothermal heat pump system integration with existing infrastructure.

Responded to service call for 10-year-old geothermal system with inadequate cooling in portion of residence. Upon inspection, examined mechanical components including buffer tank, copper refrigerant lines, and mounting hardware showing normal wear for system age. Assessed system operation and identified zoning or distribution issue affecting cooling performance in specific area of home.

Responded to service call for leaking water heater in residential basement. Upon inspection, confirmed 16-year-old tanked water heater was leaking from bottom of unit, indicating internal tank failure typical for units beyond expected service life. Documented existing installation including copper supply lines, brass fittings, expansion tank, and connections to home plumbing system. Photographed equipment configuration showing water heater positioned adjacent to HVAC system with exposed ceiling joists and utility piping. Provided assessment and recommendations for water heater replacement due to age and condition of unit.

Performed scheduled generator maintenance following extended runtime of approximately 100 hours over a four-day period during recent storm event. Inspected unit and identified oil leak requiring further evaluation. Documented equipment condition through photographs showing motor assembly, mounting hardware, and fluid management components. Service placed on hold pending technical consultation to determine appropriate repair approach for the oil leak issue.

Completed annual backflow preventer inspection and testing on a 1" Watts 375XL RP assembly (serial #AE 2780). Performed diagnostic testing using calibrated test gauges (Watts TK9A, serials 511962 and 0115394, range 0-15 PSID) on the dual check valves and relief valve. Both check valves tested at 10.5 PSI differential and relief valve at 2.4 PSI, with all components passing inspection criteria and meeting regulatory compliance standards for backflow prevention.

# HVAC Maintenance - Heating Service Report Completed preventative maintenance on two furnace units as part of MVP service program. Performed comprehensive inspection of both heating systems including burner assembly, heat exchanger, blower motor, and safety controls. Replaced heavily soiled pleated air filters on both units which showed significant dust accumulation and reduced airflow capacity. Verified proper system operation, combustion efficiency, and thermostat functionality on both furnaces. All components tested within normal operating parameters upon completion.

Performed scheduled preventive maintenance on two units under service contract. Inspected and tested control board circuitry with multimeter to verify proper operation. Replaced worn ignitor assembly with new component to prevent future heating failure.

Performed MVP furnace tune-up on unit, including inspection of internal mechanical and electrical components. Discovered severe dust and lint accumulation on heat exchanger/filter requiring thorough cleaning to restore proper airflow and system efficiency. Completed preventive maintenance to ensure optimal heating performance.

Performed scheduled MVP heating maintenance service on two units. Inspected the control board connections and wiring, noting proper connections between the circuit board and various components. Examined the blower wheel assembly which showed normal condition with no significant dust accumulation or damage, ensuring optimal airflow performance.

Responded to service call for furnace shutdown issues. Found air filter heavily clogged with dust and debris, restricting proper airflow. Replaced filter and inspected PVC exhaust vent, confirming proper installation and ventilation with no obstructions.

Responded to no heat call for Lennox furnace. Diagnosed issue with control board showing signs of corrosion. Inspected electrical connections and wiring harness. System restored to proper operation after cleaning terminals and securing loose connections.

Responded to MVP customer callback regarding drainage issue previously identified as a plumbing concern. Inspected utility room with HVAC equipment and PVC drainage system. Confirmed issue requires plumbing service as originally diagnosed, with visible evidence of drainage problems near the furnace/air handler unit.

Performed scheduled heating maintenance on 1-year-old system. Identified significant frost accumulation on evaporator coils indicating possible restricted airflow. Inspected refrigerant lines and connection points, documenting condition of copper fittings and valves for future reference.

Responded to report of flooding near furnace in 30-year-old home. Upon inspection, discovered water damage to wall panel where drywall/paneling had separated, exposing insulation material. Observed water staining on concrete floor beneath damaged area. Repaired leaking pipe connection, removed damaged drywall section, and replaced affected insulation to prevent further water intrusion.

Performed routine maintenance on 10-year-old geothermal system that experienced multiple rollover events, most recently from 11/14 to 1/12. Inspected control board circuitry and electrical connections, documenting condition of terminal blocks and wiring. Confirmed system functionality with transformer connections intact and operational status of electronic components.
