Cleaned coils and vents, performed standard maintenance checks, and restored unit to optimal operating condition.
Completed full electrical panel replacement by removing existing main lug panel and installing new breaker panel with all new circuit breakers properly labeled for household circuits including HVAC, kitchen appliances, bathrooms, bedrooms, basement, laundry, and dryer. Updated all bonding and grounding connections to current code standards and installed whole home surge protection device. All electrical work was completed with proper permits and passed required inspections, with before and after documentation photos captured for service records.
Returned to complete installation of wet switch on HVAC system in attic space following initial diagnostic by previous technician. Unit was experiencing no cooling condition, and wet switch was installed to provide proper condensate overflow protection for the air handler. Installation completed successfully, restoring system safety controls and resolving the no cool issue.
Completed preventive maintenance tune-up on outdoor condensing unit located at side of house. Inspection revealed corrosion and staining on evaporator coil fins, documented with photos. All system components checked, unit operating within normal parameters upon completion of service.
Performed complimentary second opinion evaluation on residential air conditioning system less than 10 years old following another contractor's diagnosis of refrigerant leak. Accessed attic-mounted air handler unit and conducted thorough inspection of evaporator coil assembly, refrigerant lines, and system components. Measured supply air temperature at 75.6°F and visually inspected evaporator coil condition through access panel, finding coils clean with proper fin alignment and no visible signs of refrigerant leakage, corrosion, or oil residue that would indicate leak points. Provided findings and recommendations to customer for informed decision-making regarding previously diagnosed issue.
Completed comprehensive cooling system tune-up on 4-year-old ground-level AC unit. Performed full system diagnostics including temperature differential measurements across evaporator coil (supply air reading 51.9°F), electrical testing with digital multimeter showing normal amperage draw of 0.32A, and visual inspection of all components. System operating within manufacturer specifications with no deficiencies noted.
Responded to no cooling complaint on U10 air conditioning unit located at side of home. Upon inspection, diagnosed failed capacitor preventing compressor operation. Replaced defective capacitor with proper OEM specification component, restored system to normal cooling operation, and verified all electrical connections secure.

Upon arrival, performed diagnostic assessment of indoor air handler and evaporator coil assembly. Measured supply air temperature and humidity levels using digital instrumentation to verify system operating parameters. Inspected condensate drainage system, including drain pan, drain line, and trap for proper function and potential blockages. Examined insulation integrity on refrigerant lines and condensate piping for gaps or deterioration that could cause moisture accumulation. Verified thermostat operation and system cycling at setpoint of 72 degrees. Documented system conditions with photographic evidence showing measurement readings and thermostat display. Identified source of excessive condensation and provided recommendations to customer for preventing future moisture-related corrosion issues on equipment and associated piping.
Replaced defective condenser fan motor (CFM) on residential HVAC unit. Removed failed motor, installed new replacement unit, and verified proper operation. Old part disposed of per standard procedures.
