Conducted site assessment for plumbing installation to connect propane tank to new generator at fire department facility. The generator is part of their storm shelter setup and requires proper gas line connection from the existing propane storage tank. Evaluated current infrastructure and determined optimal routing for new gas piping to ensure safe and efficient fuel delivery to the emergency power system.

Responded to a water leak complaint where water was coming through the ceiling from an upstairs bathroom. Upon inspection, identified a faulty fill valve and worn flapper assembly in the toilet tank causing continuous water seepage. Replaced the toilet flange, installed new fill valve and flapper mechanism, and verified proper water shut-off function to resolve the leak issue.

Performed scheduled HVAC maintenance service on heating system with CCGH contract (renewal 10/13/26). Replaced 20x25x4 air filter as included in maintenance agreement. Inspected thermostat displaying "Replace Air Filter" notification, which was reset after filter replacement. System operation verified with heating mode functioning properly at time of departure.

Performed initial assessment of HVAC system with particular focus on ductwork in confined space. Identified potential leak issue in the Carrier unit where flexible ducts connect to the main system. Comprehensive leak search scheduled for follow-up visit to properly diagnose and address the problem.

Returned to customer's location to replace float switch and both drain traps on Lennox HVAC system. Disconnected gas and electrical connections to access and replace the drain traps, and installed new float switch using cage stock. System properly reassembled with new components to ensure proper drainage functionality.

Diagnosed non-functioning hydro floor heating system. Inspected circuit board with illuminated LED and verified connections to wiring harness. Examined insulated piping components and associated copper lines within the system to identify the source of malfunction.

Performed preventative maintenance inspection on customer's HVAC system due to concerns about high electric bills. Inspected Richmond water heater and outdoor heat pump/AC unit which showed signs of weathering and minor corrosion. System is functioning within normal parameters; recommended continuing with regular maintenance schedule to maintain efficiency.

Completed scheduled heat maintenance on Carrier HVAC system. Inspected compressor, electrical connections, and refrigerant lines - all components in normal working condition. Replaced 14x20x1 filter and renewed maintenance agreement through 4/6/2025.

Conducted scheduled annual heating maintenance visit. Service was rescheduled from previous cancellation due to adverse weather conditions. Confirmed unit is operational and ready for continued winter use.

Performed scheduled heat maintenance on Lennox furnace and identified recurring issue with insulation detachment for the third time. Temperature testing was conducted using Cooper SH66A instrument, confirming system operation at appropriate temperature levels. Reattached insulation and noted recommendation for more permanent solution in future service visits. Customer has CCH agreement valid through 5/13/26; 20x20x4 filter not included.

Diagnosed furnace issues and determined inducer motor requires replacement. Sold repair service to customer. Will return to complete inducer motor installation on the residential HVAC furnace unit.

Performed annual heating maintenance on Carrier Infinity System. Conducted combustion analysis showing proper operation with O2 at 8.5%, CO at 41ppm, CO2 at 7.1%, and flue temperature at 97.1°F. System is operating efficiently with heat cycle functioning normally as verified on thermostat.

Inspected two leaking furnaces and identified significant corrosion on the drain pan of the upstairs unit. Documented extensive rust damage on metal condensate tray and surrounding components. The upstairs drain pan appears to be improperly positioned, contributing to the leakage issue.

Performed standard clean and check maintenance on heating system. Installed manifold gauges to test pressure readings and used digital multimeter to verify proper system operation. Customer's stepfather was present during service completion.

Responded to customer complaint of furnace running excessively with high-pitched noise. Inspected system and identified faulty Fasco blower motor (Model PR-11640, 3000 RPM) as the source. Replaced motor, cleaned components, and verified proper operation. System now functioning normally with no unusual noise.

Inspected HVAC system with severely clogged air return vent restricting proper airflow. Scheduled return visit to replace heater kit, add water to system, and perform complete maintenance service to restore optimal system operation.
