Completed system startup and verified proper operation and cooling performance.

Responded to a no-heat call on a Carrier gas furnace with a coil cabinet in a closet installation. Inspected the unit and verified supply-air temperatures at the duct with a digital thermometer, and checked the condensate PVC drain, electrical connections, and refrigerant line set for proper condition. Restored heating operation and confirmed the furnace is operating normally.

Performed annual maintenance on the natural gas-fired boiler system under the service agreement, inspecting the expansion tank, circulator pump assembly, and associated piping and fittings. Documented corrosion on the supply piping and worn paint on the circulator pump body and flange, and found the system components otherwise in serviceable operating condition.

Responded to a reported gas odor at the boiler and inspected the unit and associated gas piping. Removed the pilot assembly, which showed heavy soot accumulation and discoloration, for service and cleaning of the burner and pilot components. The system was checked for leaks and safe operation prior to being returned to service.

Responded to a no-heat callback following prior maintenance and inspected the gas furnace burner compartment, where burners were igniting and producing a stable blue flame. Verified the gas valve, gas piping, shutoff valve, and electrical connections, with no visible leaks, corrosion, or damage. Cleaned light dust and debris from the burner assembly and confirmed the unit was restored to proper operation.

Re-piped the laundry sink drain using new PVC drain piping with a wye fitting and cleanout, tied into the existing floor drain and secured along the framed wall. Replaced the laundry supply valves and angle stops with new fittings, reconnected the flexible supply lines, and protected the work area with drop cloths throughout the repair.

Repaired the toilet flange and cleared the main drain line with a drain rod to restore proper flow. Installed a new two-piece toilet, secured it to the repaired flange with a new wax seal, and tested for proper flushing, stable seating, and leak-free operation.

Performed scheduled maintenance on the furnace as part of the HVAC maintenance agreement, including inspection and cleaning of the blower assembly and housing, which showed no signs of rust, frost, or damage. Inspected the condensate pump installation, confirming the unit and its associated drain line, power cord, and wiring were intact and in serviceable condition. The system was left operating normally.

Performed scheduled maintenance on two steam boilers, including draining and flushing the boiler blowdown lines to remove sediment and sludge from the system. Inspected the gauge glass tubing, valves, piping connections, and electrical controls, with threaded fittings resealed using thread-sealing tape as needed.

Returned to replace a defective flue damper actuator motor on the recently installed boiler under manufacturer warranty. Removed the failed motor from its mounting bracket, installed the new warranty motor, and reconnected the wiring, then verified secure mounting and proper damper blade operation with no visible damage to the flue or connected components.

Inspected the laundry area drain and supply plumbing to locate the reported leak and identified staining at the base of the PVC drain assembly where it meets the floor drain. Repaired the PVC drain connections, including primed and cemented joints and fittings, and verified the braided stainless steel supply lines and shutoff valves were secure and leak-free. Tested the system under normal operation to confirm the leak was resolved.

Performed scheduled maintenance on a Carrier Infinity gas furnace, an A.O. Smith ProLine XE power-vent water heater, and a humidifier, including replacement of the 20x25x1 air filter and the 990-13 humidifier pad. Inspected the furnace cabinet, PVC intake and exhaust piping, wiring, and ductwork connections, as well as the water heater's power vent blower assembly, venting, supply piping, and expansion tank. Equipment was found in good condition with no visible rust, leaks, or damage, and all components were left operational.

Completed comprehensive maintenance inspection on furnace system per maintenance agreement. Performed visual inspection of ductwork using inspection camera to assess interior condition and identify any potential airflow restrictions or debris accumulation. Conducted temperature differential measurements using digital thermometer to verify proper heat exchanger operation and system performance. Installed new 16x25x1 filtration media to ensure optimal air quality and system efficiency.

Performed comprehensive maintenance check on two furnaces, water heater, and Aprilaire humidifier system as part of maintenance agreement. Replaced air filters including #10, 16x25x1, and 16x20x1 filters. Verified furnace operating temperature at 127.5°F and inspected all ductwork connections and mechanical components for proper operation.

Responded to callback for recently installed boiler system with customer reporting no domestic hot water. Upon inspection, verified indirect water heater connections and circulation, identified issue with aquastat control settings, adjusted temperature parameters to manufacturer specifications, and confirmed hot water delivery restored to all fixtures.

Conducted on-site evaluation for complete air conditioning system replacement and assessed feasibility of adding mini split system. Inspected existing evaporator coil assembly within air handler cabinet, documented current electrical connections and ductwork configuration, and evaluated plumbing connections at base of equipment to determine replacement requirements and compatibility with proposed new systems.

Completed annual maintenance inspection on boiler system under service agreement. Documented existing conditions including expansion tank, piping connections, and system components with photographic evidence. Observed significant moisture infiltration and efflorescence on basement brick wall adjacent to equipment, indicating ongoing water seepage issues that may require future attention to prevent equipment corrosion and structural deterioration.

Responded to report of water leaking from first-floor radiator in home with 16-year-old boiler system. Upon inspection, identified severe corrosion on radiator valve assembly and associated piping connections. The thermostatic radiator valve (TRV) and metal elbow joint showed significant deterioration with green and yellowish-brown oxidation, crusty deposits, and compromised integrity at connection points. Evidence of long-term moisture exposure was apparent with rust stains and water damage on surrounding surfaces. Repaired the leaking valve assembly, replaced corroded components, and verified system integrity to restore proper heating function and eliminate active water leak.

Conducted on-site evaluation of existing 15-year-old air conditioning system for replacement estimate. Inspected outdoor condenser unit positioned on concrete pad against exterior brick wall, noting weathered equipment and overgrown vegetation requiring clearance. Assessed indoor HVAC components in mechanical room, including furnace unit and existing ductwork configuration with PVC piping system. Documented current system specifications and spatial requirements, photographed equipment and installation areas, and provided comprehensive replacement options for new cooling system to meet anticipated 2026 replacement timeline.
