Diagnosed and successfully re-lit natural gas water heater that had pilot light failure, resolving customer's no hot water issue. Visual inspection confirmed proper ignition and operation before departure, restoring hot water service to the residence.
Responded to service call for non-functional upper level heat and system noise. Found low water pressure causing excessive wear on primary pump and air-locked zone pumps. Added water to system, purged air from loops, and restored proper pump operation. Set system pressure to 17 psi. Noted discolored water with oxygen bubbles throughout system. Recommended Fernox Treatment and replacement of primary pump due to wear.
Responded to client's report of partial heat issue with boiler system that serves in-floor radiant heating. Inspected the zoned hydronic system with multiple Taco circulators mounted on plywood backing, verifying thermostat function for two problematic zones. Confirmed both thermostats properly engage their respective pumps and that supply/return lines feel warm when called. Due to complexity of the multi-zone installation with numerous valves and copper distribution piping, scheduled follow-up visit with senior technician for further diagnosis as immediate cause of inadequate heating in upstairs bedrooms could not be determined.
Performed emergency service to decommission and properly secure a natural gas line for customer's conversion from gas to electric appliance. Inspected existing copper gas supply, identified tee connection, and implemented proper termination by installing flared fittings with caps. Verified complete elimination of leaks using TOPTES gas leak detector throughout mechanical room and adjacent piping infrastructure.
Responded to a no-heat service call for a downflow furnace that was cycling on but shutting down prematurely due to pressure switch issues. Identified water in the inducer assembly caused by a condensate line clogged with PVC shavings from installation. Cleared the blocked drain lines, removed water from inducer, and restored normal heating operation. Discussed future improvements including new lineset installation for AC issues, thermostat relocation, and proper mini-split positioning in 4-season room.
Responded to customer follow-up regarding incomplete installation of tankless water heater. Completed the required termination of exhaust venting by properly installing and securing the two PVC vent pipes on exterior wall with appropriate vent caps. All ventilation is now properly terminated according to manufacturer specifications and local code requirements.
Completed installation of two Bradford White 40-gallon tall atmospheric natural gas water heaters and two cabinet-style water softeners with inline carbon filters. Installed complete connection assembly including press dielectric unions, press ball valves, gas regulators, and new electric anode rods. All units were properly mounted and secured with threaded rod support system, and a Tru Gap air gap was installed per code requirements.
Completed water heater estimate for a duplex with two leaking 40-gallon gas water heaters sharing a single exhaust vent (non-code compliant). Recommended replacement of both atmospheric water heaters with appropriate units for the confined space. Also recommended installation of water softeners to address municipal water quality issues (high magnesium) and carbon filters to improve taste and odor.
Responded to service call for a 2-year-old Lennox HVAC system experiencing refrigerant leakage issues (requiring 3 refills since installation) and an improperly installed mini-split unit. Discussed repair options including leak detection and repair, leak sealer application (noted 50% success rate for small leaks only), or complete system replacement. Customer will contact builder regarding warranty coverage for the leak repair and schedule relocation of the mini-split head unit to the correct position.
This in floor heating system is now operating properly. Leaking Air separator replaced today.
