HVAC Durham NC

Completed full duct cleaning on a single-system, two-story residence, including supply and return ductwork that had not been serviced since 2022, using negative-pressure extraction and agitation to remove accumulated dust and debris, with borescope inspection confirming interior duct conditions. Also cleaned and cleared the second-floor dryer vent, restoring proper exhaust airflow.

Performed a preventative maintenance visit on the heating and cooling system, including an 80-point inspection on each unit, outdoor coil cleaning, burner cleaning, gas pressure adjustment as needed, and safety inspections. Inspected the crawl space evaporator coil and air handler, noting heavy dust and grime buildup and slight coil casing deformation, and documented equipment condition with photos.

Responded to a no-heat complaint on a 2019 single-system unit. Inspected the air handler housing and identified a hairline crack along the interior wall, along with a deteriorated gasket seal secured by foil tape. Performed a borescope inspection of the ductwork and surrounding cavity to assess airflow path and internal condition, and documented findings with photos.

Responded to a no-heat complaint on a packaged unit installed within the past year. Connected diagnostics to the unit and found an active T117_F alarm indicating a motor RPM detection failure, pointing to a fault with the motor or its feedback circuit. Inspected the control wiring compartment and noted corrosion on a refrigerant/piping fitting. Thermostat was calling for heat with the system in Heat mode but the unit was not satisfying the call. Documented findings with photos for warranty review and further repair of the faulty motor.

Responded to a reported animal damage concern on the crawlspace ductwork and inspected the accessible duct runs and air handler cabinet. The air handler blower motor, wiring, and housing were clean and intact, and the flexible duct connection at the plenum opening was found in serviceable condition with only minor fraying of the foil-faced insulation at the collar edge. No evidence of significant duct damage was documented in the inspected areas.

Performed preventive maintenance on one system, including a complete 80-point heating and cooling inspection, outdoor coil cleaning, burner cleaning, and gas pressure adjustment to manufacturer specifications. Verified static pressure with a digital manometer and measured component amperage draw with a clamp meter, and completed all safety inspections with no damage or corrosion observed.

Completed comprehensive heating and air maintenance on 2016 whole-home system, including 80-point inspection, outdoor coil cleaning, burner cleaning, and gas pressure adjustments as needed. Performed electrical diagnostics with multimeter to verify proper voltage and system operation, confirmed all circuit breakers functioning correctly in main electrical panel. All safety inspections passed with system operating within manufacturer specifications.

Responded to no-cooling complaint with indoor temperature reading 77°F against 72°F setpoint and outdoor unit fan noise. Upon arrival, performed diagnostic assessment of split system HVAC unit. Inspected outdoor condensing unit and identified faulty condenser fan motor producing excessive noise and vibration, contributing to reduced system performance. Conducted electrical diagnostics using Fluke 301D clamp meter to verify capacitor functionality, measuring 38.52 µF on the run capacitor. Tested voltage and amperage at compressor and fan motor terminals to confirm electrical supply and component operation. Found capacitor readings within acceptable range, ruling out capacitor failure as primary issue. Examined indoor air handler and zoning system components. Documented three-zone damper control system with Honeywell zone panel controlling airflow distribution to multiple areas. Verified zone damper operation and sequencing to ensure proper air delivery throughout conditioned spaces.

Completed comprehensive heating and air maintenance on single HVAC system including 80-point inspection, outdoor coil cleaning, burner cleaning, gas pressure adjustments, and safety inspections. Outdoor condenser unit showed significant weathering and heavy accumulation of dirt, debris, and biological growth on exterior casing with darkened coil fins requiring thorough cleaning. Performed combustion analysis measuring gas pressure at 0.16" W.C. to ensure proper system operation and efficiency.

Completed comprehensive Heating & Air Maintenance including full 80-point inspection on both heating and cooling systems. Performed outdoor coil cleaning, burner cleaning, and adjusted gas pressures to manufacturer specifications. Conducted static pressure measurements in attic ductwork using digital manometer, recording readings to verify proper airflow and system performance. Inspected attic-mounted air handler unit, verifying electrical connections, capacitor operation, and condensate drain pan condition. All safety inspections passed with systems operating within normal parameters.
