Replaced noisy blower motor in bedroom ductless mini-split head unit. Performed additional cleaning of the system to address customer concern about air quality issues. Parts were ordered through comfort advisor for this first service call, with installation completed upon parts availability.
Completed warranty repair on heating system by installing replacement control board sourced from Johnstone. Verified proper system operation using Testo 510i diagnostic tool, with post-repair readings confirming successful restoration of heating function.
Responded to emergency no-heat call for 10+ year old boiler system. Found multiple issues including power/gas shutoff, low pressure, failed circulation pump, plugged vents, compromised expansion tank, and worn thermocouple. System also exhibited problems with seized water supply valve and required air vent replacement. Restored system functionality by addressing critical components; customer was advised of additional concerns regarding piping and air separator that will require future attention.
Diagnosed furnace shutdown during heating cycle. Determined circuit board was failing when gas valve energized, preventing ignition. Replaced defective control board to restore proper ignition sequence and heating function.
Responded to no heat service call for 15+ year old furnace exhibiting intermittent operation. Diagnostic inspection revealed two cracks in heat exchanger, presenting a significant safety hazard. Recommended complete heat exchanger replacement or full furnace replacement as appropriate remedial options given system age and condition.
Performed follow-up inspection after recent mini split deep cleaning to address customer's concerns about black tar-like particles staining carpet. Observed minor debris on floor consistent with normal post-cleaning residue. Documented condition of evaporator coils and surrounding area with photos. Advised customer that similar minor debris may occur with future cleanings due to normal system purging process.
Performed comprehensive cleaning of multiple mini-split air handler units, finding extreme contamination including a mice nest in one unit. Sealed access hole to prevent future infestations. Identified loud motor operation in one unit likely due to prolonged overwork. Two units remain to be cleaned during scheduled follow-up visit, with recommendation for motor or complete head replacement on affected unit.
Conducted complete inspection on 21-year-old gas furnace. System burning safely with solid electrical connections. Identified and replaced out-of-range capacitor that would have caused operational issues. Verified clean filter and burners. Performed electrical testing with clamp meter showing 4.759 amp reading, confirming system is operating within normal parameters.
Responded to gas leak detected during Centerpoint home audit. Located and repaired gas leak, replaced deteriorated shutoff valve on copper supply line, and recommended replacement of water heater ignitor due to signs of wear.
Performed furnace tune-up on aging Carrier natural gas system. Diagnostic testing with C16T Combustion Analyzer revealed secondary heat exchanger beginning to fail, with CO levels fluctuating above 100 ppm. Due to age of unit and safety concerns, recommended and completed replacement of the entire furnace system.
Diagnosed furnace issue where unit wouldn't stay lit due to heavily contaminated flame sensor and excessive dust accumulation in combustion area. Performed thorough cleaning of flame sensor rod and vacuumed out dust/debris from panel and surrounding components. After service, verified proper operation with successful ignition and sustained flame, resolving the no-heat condition.
