HVAC Pittsboro NC

Completed comprehensive spring preventive maintenance on single HVAC system approximately 10 years old, including full 80-point inspection of heating and cooling components. Performed outdoor coil cleaning, burner cleaning, verified and adjusted gas pressures to manufacturer specifications at 0.12" W.C., and conducted thorough safety inspections of all electrical connections and control wiring. All system components operating within normal parameters upon completion.

Completed full HVAC heat pump installation at residential property. Installed outdoor condenser unit on concrete pad with proper clearances, mounted and wired electrical disconnect box on exterior wall, and ran refrigerant lines and electrical conduit through exterior siding. Interior work included installation and wiring of air handler unit in utility area, connection to existing electrical panel with dedicated circuit labeled for heating system and main floor zone, and integration with home's electrical infrastructure. All electrical connections completed to code specifications, refrigerant lines properly insulated and secured, and system tested for proper operation upon completion.

Responded to no-cool condition on downstairs unit of a two-system residence with 2021 equipment. Upon arrival, confirmed thermostat was set to 71°F but no airflow from registers and outdoor unit not energizing. Inspected air handler and found condensate pump failure causing safety float switch activation, which shut down system operation. Condensate drain pan showed significant sediment buildup and staining indicating prolonged water accumulation. Cleared blockage from condensate drain line, cleaned drain pan, and tested pump operation. Verified proper drainage flow through PVC condensate piping. Cycled system successfully with outdoor unit engaging and airflow restored to all registers. Upstairs unit operating normally with no issues noted.

Responded to no cool complaint on upstairs unit struggling to maintain temperature below 78 degrees during hot weather. Performed diagnostic evaluation using digital clamp meter to measure electrical parameters including amperage and voltage readings on system components. Inspected capacitor, control board, and wiring connections for proper operation. Evaluated system performance to determine if unit required refrigerant recharge or had other underlying issues affecting cooling capacity. Verified electrical values were within acceptable ranges and assessed overall system functionality to identify cause of inadequate cooling performance.

Responded to no cooling complaint with indoor temperature at 80°F despite thermostat set to 72°F on a 2024 system. Performed diagnostic testing using digital instrumentation to measure system performance parameters at the air handler and ductwork components. Based on the intermittent cooling issue and difficulty maintaining setpoint during high ambient temperatures, evaluated airflow, refrigerant pressures, and system operation to identify the root cause of inadequate cooling capacity.

Responded to no cooling complaint on upstairs system of dual-zone residence with 8-year-old equipment. Upon inspection, found evaporator coil severely frozen with ice buildup, preventing proper airflow and heat exchange. Advised customer to power down system to allow complete thaw of coil and insulation. Observed moisture damage to surrounding insulation and identified potential airflow restriction or refrigerant issue requiring follow-up diagnostic once coil defrosts.

Completed comprehensive heating and air maintenance on two 2020 HVAC systems, performing an 80-point inspection on each unit. Cleaned outdoor condenser coils on both units, performed burner cleaning, adjusted gas pressures to manufacturer specifications, and conducted thorough safety inspections to ensure proper system operation for the heating season.

Completed HVAC system installation with new Honeywell Home digital thermostat programmed and operational in cooling mode. Installed Kidde Carbon Monoxide Alarm as required safety device to meet code compliance. All equipment tested and verified functioning properly with customer walkthrough of thermostat operation and alarm features provided.

Responded to no cooling complaint on 24-year-old system. Upon arrival, confirmed unit was blowing air but not cooling. Inspected attic-mounted air handler and associated ductwork. Examined electrical connections, contactor assembly, and control components. Documented existing equipment configuration including silver metallic supply duct, black flexible return ductwork, condensate drainage system with PVC piping, and mounted control box. System showed age-appropriate wear on mechanical components including contactor housing with visible oxidation on brass elements and surface deterioration on painted surfaces. Photographed equipment for service records.

Responded to permit correction callback for furnace installation. Upon inspection, identified that the unit was factory-configured for natural gas but required propane conversion per permit specifications. Conversion kit had not been installed during initial setup. Documented existing configuration with photos showing interior components, gas line connection, and current factory settings. Advised that propane conversion kit must be installed, conversion sticker applied to unit, and municipal inspection rescheduled before system can be approved for operation.
