Sparta NJ – HVAC Service

Responded to no cooling call and performed diagnostic testing on HVAC system control board. Upon inspection, identified failed expansion tank requiring replacement. Removed existing expansion tank and installed new unit. Verified all electrical connections to control board, including relay components and capacitor. Tested wire connections with multimeter to ensure proper voltage and continuity throughout system. Secured all wire nuts and verified proper connection of yellow, green, white, and brown wiring to circuit board terminals. Confirmed flexible metal conduit connections were secure and properly routed. Cycled system through complete operational test to verify cooling function restored and all components operating within normal parameters.

Responded to service call for water dripping from boiler and water smell associated with AC operation. Upon arrival, inspected hydronic heating system including AMTROL expansion tank, Burnham MPO-IQ circulating pump, and associated copper piping network. Examined AC unit components including compressor, refrigerant lines, and copper coil assembly for signs of condensate leakage or drainage issues. Verified AC units were operating and providing adequate cooling. Documented system conditions with photographs showing plumbing connections, pressure tank installation, and HVAC components. Customer reported water smell dissipated when AC units were turned off, suggesting potential condensate drain concern rather than boiler leak.

Completed seasonal maintenance on two air conditioning systems. First unit exhibited severe coil corrosion with extensive oxidation on copper tubing showing multiple colors of patina, indicating prolonged moisture exposure and chemical degradation. Second unit contained substantial accumulation of organic debris including grass, leaves, and nesting material that was removed from the interior housing. Both systems were inspected, cleaned, and serviced per manufacturer specifications to restore proper operation.

Performed comprehensive leak test on residential AC system including condenser unit, branch box, and two air handler units. Testing revealed significant ice buildup on one air handler, indicating potential refrigerant leak or airflow restriction requiring further diagnosis. Verified proper operation of installed Honeywell enviracaire ELITE ultraviolet air treatment system during inspection.

Responded to urgent no cooling call at commercial building. Upon arrival, performed system assessment to identify affected unit among multiple HVAC systems on property. Conducted visual inspection of outdoor condensing unit and associated components, including compressor, condenser coil, refrigerant lines, and electrical connections. Documented equipment conditions with photographs showing copper line sets, condenser coil with aluminum fins, and overall installation configuration. System evaluated for proper operation and potential causes of cooling failure.

Responded to no cooling call following thermostat installation. Upon inspection, found HVAC system with Honeywell Enviracaire Elite ultraviolet air treatment system installed on ductwork. Diagnosed thermostat wiring issue preventing system communication. Corrected thermostat connections, verified proper 24V control circuit, and tested system operation. Unit now cooling properly with thermostat responding to temperature calls.

We will diagnose the system to determine what type of additional work or repairs is necessary to restore the system back to proper working conditions.

Received a call that the heat was not working however the fan is running continuous. Upon arrival I found that it is a heat pump system with electric heat, I did confirm that the heat pump was not running and the electric heaters were not being energized however the blower was running continuous. Upon troubleshooting I found that the thermostat is not a heat pump thermostat, the system was wired for a conventional heating setup however the low voltage wiring for the electric heater strips were not connected. The homeowner for me that they had the thermostat replaced over the summer, it was a customer supplied nest thermostat that they had received from the utility company.
