Diagnosed no heat condition on residential furnace with cold air blow. Found rusted burners causing rollout switch to trip. Inspected heat exchanger (no issues found). Replaced original components with stainless steel burner kit compatible with Goodman furnace. System tested for 20 minutes with proper operation and no rollout issues.
Added 10 gallons of ProTek glycol freeze protector to the boiler system, achieving 30% concentration as specified in the estimate. Identified and repaired a gas leak at an old tee connection to the water heater by cutting out the deteriorated section and installing a coupling. Performed operational testing to verify proper circulation and heating function of the boiler system with all components now working correctly.
Diagnosed non-functional Richmond water heater (NG, power vent, 7-10 years old) with broken pilot light and thermal pile assembly. Removed damaged assembly components and placed order for replacement parts. Provided customer with estimate for new assembly installation.
Responded to service call for non-functioning boiler system. Diagnosed significant air entrapment in system causing circulation issues. Performed air bleeding procedure on the Hydr Smart circulator pump assembly. Observed abnormal heating cycle - unit rapidly reaching temperature and shutting down prematurely due to suspected persistent air pocket preventing proper water circulation. Recommended follow-up service by technician with prior system knowledge to fully resolve the circulation impediment.
Diagnosed water leakage issue under furnace and hardwood floor. Investigation revealed improperly terminated water heater condensate drain was causing backflow. Resolved by correctly terminating the condensate drain at floor drain with an elbow, preventing further water damage.
Inspected 12-year-old water heater and water softener system per customer concern about egg odor in laundry room. Determined both units are functioning properly, with odor likely caused by washer discharge pipe being inserted too far into standpipe, causing P-trap siphoning. Repositioned discharge hose to proper depth and advised customer on cleaning tub overflow to address separate odor issue in that location.
Performed comprehensive furnace tune-up on 6-year-old system, including filter replacement, condensate drain clearing, and gas pressure verification. Conducted electrical testing with clamp meter showing 58.5 reading and inspected relay/capacitor components and associated wiring. All systems operating correctly with heat exchanger in good condition.
Responded to service call for non-functioning water heater with reported gas leak. Upon inspection, discovered flame rolling out through side panel due to dirty components rather than faulty gas valve or burner assembly. Performed thorough cleaning of flue vent and burner assembly. Additionally, identified and replaced non-functioning temperature and pressure relief valve to restore proper safety function. Water heater now operating correctly with proper flame containment.
Responded to no heat call for 2017 furnace (80% efficiency). Performed operational check with system firing up three times normally. Conducted electrical testing with multimeter and confirmed proper functioning of inducer and blower motors. System is operational but noted significant dirt accumulation requiring maintenance. Advised customer of installation configuration issue that would complicate future blower removal due to refrigerant line placement. Recommended system replacement when major component failure occurs.
Performed annual furnace tune-up on 8-year-old FRP unit. Completed comprehensive inspection including heat exchanger examination, combustion analysis, gas pressure verification, flame sensor and burner inspection, and blower motor assessment. Replaced severely clogged air filter and cleaned pressure switch. System is currently operating normally with no immediate concerns. Recommended quarterly filter replacement due to pet presence to prevent potential overheating issues.
Responded to no-heat call for York RTU serving center office area. Upon arrival, conducted diagnostic inspection of unit. Heat exchanger was examined and found to be in good operational condition with no signs of damage or deterioration. System was cycling properly during inspection with no observable issues. Visual inspection of burner assembly confirmed proper operation. No service actions required as system was functioning normally at time of service.
Diagnosed boiler system experiencing insufficient circulation due to air-lock condition. Removed and replaced a section of 1" copper piping as requested by homeowner. Performed system purge to eliminate air entrapment, thawed a blocked baseboard loop restricting flow, and restored normal circulation. Established proper water pressure at 20 psi, verified burner operation and gas pressure. System returned to normal operation with supply and return lines heating correctly. Note: Third zone remains intentionally shut as homeowners are aware and currently remodeling that area.
Responded to callback for no heat upstairs. Identified air lock in the system and resolved by bleeding significant air from purge valves where lines ascend to upper floor. Found and closed an incorrectly opened bypass valve which restored proper flow. System currently operational but noted several design issues including incorrectly piped expansion tank and questionable piping configuration. Recommended installation of conventional bladder tank with air scoop, auto fill, repipe on boiler return, and addition of glycol due to pipes running along exterior walls in this historic structure.
Diagnosed non-operational humidifier on previously installed HVAC system. Verified 24V power supply to solenoid using Fluke 365 True RMS Clamp Meter and confirmed solenoid resistance at 35.5 ohms. Observed intermittent clicking of faulty solenoid that remained in closed position despite proper voltage. Replaced defective solenoid to restore proper humidifier function.
Performed tune-up maintenance on 21-year-old Carrier 80% furnace. Discovered dirty blower wheel, oil leaking from blower motor, and heat exchanger in deteriorated condition with potential crack that was documented with photos and discussed with customer. Cleaned blower motor and wheel, and recommended comfort advisor consultation regarding the aging system components.
