Responded to no-heat call for aging boiler system showing Low Water Pressure error. Utilized transfer pump to replenish water in the closed hydronic heating system, which services in-floor heating on lower level and portions of upper floor. During diagnostics, identified water leakage from manifold zone actuator requiring replacement, along with evidence of water damage to additional components. Recommended replacement of upstairs manifold pump flange and faulty pressure gauge. Restored system pressure to operational levels and provided repair estimates.
Removed and capped boiler baseboard piping behind toilet. Assessed existing toilet installation and determined need for flange repair, new bolts, and wax ring replacement due to improper previous installation. Provided customer with estimates for installation of two customer-supplied toilets including necessary closet flange repair and shut-off valve replacement.
Performed inspection of two 2017 Bradford White 50-gallon natural gas water heaters to investigate reported condensation at base of units. Customer had previously observed moisture around one heater, but no active leakage or condensation was detected during inspection. Both units appear to be functioning normally at present. Provided customer with replacement options including dual 50-gallon heater installation or upgrade to single 75-gallon unit.
Performed diagnostic inspection on 10-year-old Goodman furnace as second opinion. Verified primary heat exchanger integrity but identified corrosion at secondary heat exchanger where tubes connect to collector box, indicating early-stage failure. Conducted electrical system verification with multimeter and inspected control board functionality. No immediate safety concerns warranting shutdown, but recommended replacement options due to heat exchanger deterioration.
Responded to no heat complaint on 7-year-old Luxaire furnace. Diagnosed system with only one burner igniting during heat call. Upon inspection of burner assembly, found low fire side of gas valve coil was open. Attempted to clean orifices but gas valve subsequently failed to operate. Recommended replacement of gas valve and burner assembly or furnace replacement as alternative solution due to deteriorated condition of burner components.
Performed comprehensive boiler tune-up on Bradford White water heater Combi unit. Inspected heating system components including pilot light, pumps, manifolds, and zone valves. Cycled system to verify proper operation of all zones and confirmed thermostat functionality.
Diagnosed and resolved heat pump operational issue with a recently installed Lennox system. Heat pump was not engaging during heating cycles, allowing only furnace operation. Adjusted High Balance Point settings on the Lennox thermostat and cycled the system to verify proper operation. Confirmed system returned to normal operation with appropriate set points.
Responded to service call for Lennox furnace with error code 200 (open limit switch). Identified loose Molex plug connection at the control board as the source of the issue. Properly reconnected the connector and verified complete system operation. Furnace now functioning normally with no error codes present.
Responded to a service call for HTP boiler intermittently entering purge mode and displaying low water code. Performed diagnostic testing on the low water pressure switch per manufacturer specifications, which yielded 3.5 ohms indicating component failure (manual specifies 0 ohms for proper operation). Verified proper system water pressure and cycled all zones to confirm functionality of remaining components. Recommended replacement of the low water pressure switch and control board, with estimate to follow.
Completed complimentary inspection of furnace heat exchanger and confirmed presence of compromised heat exchanger with visible hole. Heat exchanger was replaced to restore system integrity and safe operation.
