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.

Arrived onsite for adding an updated thermostat that is capable of running dual heat: heat pumps and electric heat.

Performed the maintenance for the oil fired hot water boiler, replace the nozzle, and oil filter. Open and brushed and vacuumed the heat exchanger, brushed and cleaned the electrodes. Reassembled all the components and started up the burner and confirmed that it has fired and is properly running.

Arrived on site for a suspicious oil smell that the homeowner is smelling while the unit is running. Found out that the Chamber of the unit is leaking water, meaning a cracked cast iron. You didn't need to be replaced, gave homeowner estimate and options for replacement unit. Homeowner said they'll discuss it with their wife.

Arrived on site for heating maintenance. Home owner stated no issues with unit as of late. Confirmed unit's operation/functionality. Turned unit off to operate on it safely. Closed off oil valve. Replaced filter.

Arrived on site for heating maintenance. Customer stated no issues with heating as of late. Did state that about two inches ago not all burners return on correctly but it hasn't been giving that issue recently. Checked flame sensor, removed it and cleaned it thoroughly. Reinstalled the flame sensor properly. Turning on to inspect the microamps on the flame sensor. Microamps reach 2.7. Check combustion analyzer test results. Co was at 30ppm Efficiency reached 89.7%

Arrived onsite to repair faulty Domestic hot water valve on NTI boiler. Started by shutting down the system and isolating the zone valves. Drained the boiler. Removed the wiring and faulty valve. Installed new valve supplied by NTI manufacturer. Used new washer that were supplied. Wired back into the system.

Confirmed system is operating and heating properly at this time.

Arrived on site for two furnace heating maintenance. Both units was already calling for heating upon arrival. First floor units seem to be operating fine, turned off the gas to inspect it safely. Remove flame sensors to thoroughly clean the plane sensor. We installed the safety frame sensor and the Michael Williams reading was 2.2. Flames seem to be in control when ignited. Customer does not want to change the filter today, says they only change it once a year, Aprilaire 413.

Early afternoon arrival; She may have to leave around 2 to get kid, will be back around 3:30. EPP 2H- Propane Gas Furnace Maintenance (and heat pump too) . Customer is aware filters need to be on site to be changed.

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.
