HVAC Cary NC

Responded to no cooling complaint on upper level air handler system. Upon arrival, diagnosed intermittent power cycling issue affecting thermostat operation. Performed electrical diagnostics using clamp meter to verify amperage draw and voltage supply at air handler located in attic space. Identified and resolved power supply issue causing unit to cycle on and off unexpectedly. Verified proper system operation with stable amperage readings of 77.4A and confirmed unit maintaining consistent power to thermostat. System restored to normal cooling operation with no further cycling issues observed.

Completed comprehensive fall preventive maintenance including 80-point inspection on all HVAC units. Cleaned outdoor coils and burners, verified and adjusted gas pressures to manufacturer specifications, and performed thorough safety inspections. Inspected ductwork system and tested electrical components with multimeter to ensure proper system operation and heating readiness.

Completed full HVAC system replacement including removal of existing equipment and installation of Lennox EL18KSLV-036 3-ton cold climate heat pump condenser with side discharge configuration and Lennox CBK48MVT-036 Signature Series 3-ton air handler. Installed new outdoor condenser pad, float switches for condensate overflow protection, and Lennox E40 thermostat for system control. Performed complete system startup, verified electrical connections at panel, ensured proper leveling of equipment, tested all safety controls, and confirmed operational parameters meet manufacturer specifications.

Responded to service call for reported water leak in crawlspace that was initially suspected to be HVAC-related. Accessed crawlspace and inspected both HVAC systems, condensate drain lines, and evaporator coil drain pans for signs of leakage or overflow. Examined PVC condensate drainage piping and verified proper pitch and flow. Inspected air handler units and surrounding areas for moisture, staining, or active dripping. Found no evidence of HVAC equipment malfunction or condensate system failure causing the reported leak. Systems operating properly with adequate cooling performance and normal condensate drainage function.

Completed comprehensive heating and air maintenance including 80-point inspection on both HVAC units. Performed outdoor coil cleaning, burner cleaning, and adjusted gas pressures to manufacturer specifications. Conducted thorough safety inspections of all system components including electrical connections, capacitors, contactors, and heat exchangers. Verified proper operation of all mechanical and electrical systems, inspected condensate pump and drainage system, and confirmed all wiring connections were secure and properly terminated.

Responded to no cooling call at commercial building with 11+ year old system. Upon arrival, confirmed outdoor condensing unit was not operating. Tested capacitor using Fluke 301D clamp meter and found failed run capacitor preventing compressor from starting. Replaced defective GE 370VAC capacitor with new unit, restored power, and verified system operation with proper compressor startup and cooling cycle.

Responded to second opinion request on 9-year-old system reported to have refrigerant leak by previous contractor. Performed diagnostic evaluation of outdoor condenser unit with electrical measurements using clamp meter. Inspected indoor blower assembly and evaporator components, noting dust accumulation on blower wheel indicating maintenance needs. Provided assessment findings to verify system condition and refrigerant leak diagnosis.

Responded to no cooling complaint on residential air conditioning system. Upon arrival, performed visual inspection of outdoor condensing unit and found condenser coil heavily obstructed with dirt, dust, and debris accumulation, particularly in lower two-thirds of coil surface. Excessive buildup was restricting airflow through coil fins, significantly impeding heat transfer capability and preventing unit from operating efficiently. Accessed electrical compartment and performed diagnostic testing of system components. Used clamp meter to measure capacitance of run capacitor, obtaining reading of 35.82 μF. Verified capacitor specifications against manufacturer nameplate on REPHON brand capacitor. Inspected refrigerant line connections and electrical wiring for signs of damage or deterioration. Primary issue identified as severely restricted condenser coil preventing adequate heat rejection from refrigerant system, resulting in loss of cooling capacity. Recommended thorough coil cleanin

Responded to a no-cool service call to provide a second opinion on reported coil issues for an 11-20 year old HVAC system. Upon inspection, found evidence of significant deterioration and rust accumulation around the evaporator coil housing and blower assembly, indicating moisture intrusion and potential refrigerant leak concerns. Documented equipment condition with photographs showing corrosion patterns on coil access port and aging blower motor components, confirming the need for coil evaluation and possible replacement to restore proper cooling operation.

Completed comprehensive heating and air maintenance on 2012 single-system unit including 80-point inspection, outdoor coil cleaning, burner cleaning, gas pressure adjustments, and safety inspections. Tested capacitor function using clamp meter, which showed 29.21 µF reading on MARS capacitor. Replaced heavily soiled air filter with clean unit to restore proper airflow and system efficiency.
