Responded to residential service call for low water pressure throughout property. Diagnostic assessment revealed high water pressure caused by faulty pressure reducing valve (PRV) and simultaneously low water pressure due to fouled water softener. Provided homeowner with options for water treatment system and PRV replacement to restore proper system pressure and functionality.
Responded to a service call to verify operational status of a furnace and water heater after customer accidentally shut off gas supply. Both appliances were confirmed functioning correctly through operational testing - hot water demand successfully triggered water heater ignition and thermostat adjustment verified proper furnace heating function. Advised customer against partial gas valve closure due to potential equipment damage from improper gas pressure. Documented condition of Bradford White water heater and residential furnace with exhaust and condensate systems intact.
Performed safety inspection on 25-year-old direct vent heater in detached loft. Verified no gas leaks, no heat exchanger cracks, and no CO leakage. Identified non-operational blower motor and absence of high limit safety switch, with recommendation to consider replacement as heat exchanger is at risk of cracking under continued stress.
Performed comprehensive inspection of furnace and water heater gas systems. Verified proper operation of all gas valves, turning off fireplace and range valves per customer request. Conducted full diagnostic on furnace, examining burners, blower, inducer, pressure switch, safety switches, limit switches, flame sensor, igniter, gas pressures, and combustion air. Water heater inspection confirmed functioning pilot light and proper system operation. Both systems operating normally and safely.
Performed comprehensive inspection on 35-year-old furnace experiencing intermittent short cycling issues. Examination revealed secondary heat exchanger has rusted through, and evidence of system overheating was observed with significant dust accumulation on blower assembly. Recommended complete furnace replacement due to age and safety concerns.
Successfully replaced customer-supplied thermostat (Honeywell Home ProSeries) to replace previous ecobee model. Identified need for 5-wire configuration for proper thermostat operation and recommended electrical work for new thermostat wire installation. Customer advised to schedule electrician for quote on necessary wiring modifications.
Performed diagnostic service on 22-year-old Skymark furnace with no-heat complaint. Inspection revealed failed control board outputting insufficient voltage (6V) to draft motor relay during heat call. Visual examination using borescope identified significant rust and potential pinholes on heat exchanger, creating unsafe operating conditions. Customer informed that manufacturer is defunct and replacement parts would be difficult to source. Service advisor appointment scheduled to discuss replacement options.
Inspected 30+ year old Hydro Therm natural gas boiler system that was functioning but experiencing water distribution issues. Verified boiler operation was normal despite customer's complaint about inconsistent heating in back bedroom. Customer has mini-splits installed as backup heating and prefers to maintain current system rather than replace aging unit. Noted handwritten instruction to "Keep at 10 PSI" on pressure gauge.
Successfully completed pressure switch replacement on furnace. Unit required a 2-hour service call to remove defective component and install new pressure switch sourced from WC Johnstone Bloomington (PO 203395-001). Post-installation testing confirmed furnace is now operating correctly.
Diagnosed intermittent operation on 24-year-old Lennox gas furnace. Found weak flame sensor causing system shutdowns and identified early-stage heat exchanger deterioration with separating rings. Replaced flame sensor to restore proper operation and scheduled follow-up service advisor appointment to address heat exchanger concerns.
Responded to kitchen sink clogging issue. Inspected under-sink plumbing system and found water accumulation in catch basin below P-trap. Performed drain service and offered snaking procedure; recommended hydro-jetting for more comprehensive clearing of the drainage system to prevent future blockages.
Performed annual maintenance inspection on a 7-year-old Navien boiler. System tested normal with no active leaks, proper system pressure, functioning safety controls, and good operational condition of all zones, air eliminators, and expansion tank. Combustion analysis confirmed proper and safe burning performance. No corrective actions required.
Located shutoff valves for outdoor spigots that customer was unable to find. Inspected existing plumbing system and found copper pipes with significant oxidation and corrosion. Provided bid for replacing deteriorated shutoff valves and installing an additional valve for improved system control.
Responded to callback regarding air in boiler system causing noise through main level. Upon arrival, performed system bleeding to remove trapped air. Pressure gauge inspection showed appropriate system pressure following service. Previously installed zone valve for bedroom zone remains operational.
Responded to no-heat call for 15+ year old natural gas garage heater with inoperative blower motor. Found gas supply to garage was shut off. Performed diagnostic testing on control valve and blower motor assembly, verified proper voltage with multimeter. Restored heat functionality by turning on gas supply and ensuring proper ignition sequence.
