HVAC Pittsboro NC

Responded to a no-heat complaint on the downstairs 15-year-old system, which operates normally in cooling mode. Inspected the furnace control compartment and found aged, cluttered low-voltage wiring and wire nut connections at the control board, and checked the wire nut connection integrity. Used a True RMS clamp meter to measure amperage draw (13.47 A AC) to evaluate component operation and diagnose the heating failure.

Responded to a no-cool call on the upstairs heat pump system with the thermostat displaying "Waiting For Equipment." Inspected the thermostat wall plate and low-voltage wiring connections (Y, G, O/B, C, R) to verify control signal continuity and proper wire termination between the thermostat and air handler. Documented thermostat settings and wiring configuration for further diagnosis of the communication fault.

Performed seasonal heating and air maintenance on two systems, including an 80-point inspection on each unit, outdoor coil cleaning, burner cleaning, and safety inspections. Adjusted gas pressures as needed and verified readings with a digital differential manometer to ensure proper operation.

Identified biological growth forming in ductwork serving both HVAC systems in a two-story, 3,425 square foot residential property with unfinished attic access. Installed Air Scrubber by ActivPure UV air purification units on both systems to address indoor air quality concerns and prevent further microbial contamination. Accessed attic space through ceiling hatch to complete installation, securing purification devices directly to supply ductwork with proper mounting hardware and ensuring optimal placement for maximum air treatment effectiveness.

Completed comprehensive heating and air maintenance on single-system residential HVAC unit installed in 2025. Performed 80-point inspection covering all major components, cleaned outdoor coils, performed burner cleaning, verified and adjusted gas pressures to manufacturer specifications, and conducted full safety inspections. Inspected attic-mounted air handler with flexible ductwork installation, verified proper condensate drain operation via PVC P-trap configuration, and checked low-voltage control wiring connections and transformer functionality to ensure system reliability.

Responded to after-hours call for air conditioning system not turning on. Upon arrival, verified system was non-operational and began diagnostic procedures. Measured supply air temperature at 75.2°F at return vent, confirming lack of cooling. Accessed attic space to inspect ductwork and air handler components. Examined sheet metal trunk line connections and flexible duct transitions for proper installation and airflow restrictions. Found issue preventing system startup and restored unit to normal operation. System tested and confirmed cooling properly before departure.

Responded to service call for malfunctioning thermostat at vacant residential property with single heat pump system. Upon arrival, inspected existing thermostat and documented wiring configuration, which showed proper connections to heat pump terminals including Y2, C, W1, RC, RH, O/Y, and G wires. Photographed thermostat backplate and wiring for reference, as customer had been advised prior to visit that thermostat replacement falls outside our scope of service.

Completed comprehensive heating and air maintenance on three HVAC systems covered under preventative maintenance agreement. Performed 80-point inspection on each unit, including cleaning of outdoor coils, burner cleaning, gas pressure adjustments, and thorough safety inspections. Inspected blower assemblies, electrical connections, and air distribution components. All systems operating within manufacturer specifications upon completion.

Responded to no cooling complaint on 7-year-old residential air conditioning system. Upon inspection, found condensate safety switch tripped due to clogged drain line, preventing system operation. Cleared blockage from condensate drain, tested switch functionality, and verified proper drainage. Reset safety switch, confirmed system startup, and monitored unit through complete cooling cycle to ensure proper operation and adequate airflow.

Completed comprehensive spring preventive maintenance on three HVAC systems covering 2017 installation, performing 80-point inspections on each unit including outdoor coil cleaning, burner cleaning, gas pressure adjustments, and safety checks. Inspected and documented third-floor air handler unit (Model FEM4X2400CL, Serial F223444034, manufactured August 2022) with 410A refrigerant system rated at 208/230V. Verified proper operation of condensate pump assembly with associated PVC drainage lines and electrical connections, ensuring all safety controls and drainage systems functioning correctly across all units.
