Performed a heating pm on an oil boiler. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Started and checked the safeties. Performed a combustion test. 5.2% o2, 28 ppm, 85.2% efficient System is operating properly.
Furnace Tune-Up- Raised the ductwork starting at the furnace all the way to the end and properly securing the evaporator coil to the furnace. Taped and sealed the joints. Performed a heating preventative maintenance service on a gas furnace. Removed and cleaned the flame sensor. Blew out the drain line and trap. Checked the gas pressures, 16” wc incoming/ 9.6” wc at the manifold. Replaced the air filter, 14x24x1 Started and checked the safeties. Performed a combustion test. 9.0% o2, 19 ppm, 90.6% efficient. System is operating properly.
HVAC and Water Heater Maintenance Service- Performed preventative maintenance on an oil furnace and oil water heater. Brushed and vacuumed. Replaced the oil filter, nozzles and strainer. Started and checked the safeties. Performed a combustion test. System is operating properly. Inspected the heat exchanger on the furnace and found a crack on the back of the heat exchanger. There is a hole on the back side of the chamber allowing excess heat hit the metal of the heat exchanger. Recommend replacing the furnace.
Autumntime HVAC System Maintenance- Performed preventative maintenance on an oil boiler. Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 8.7%o2 1ppm co 0 smoke
HVAC Maintenance Service- Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 1%o2 14ppm co 0 smoke While performing the maintenance we found very high levels of sludge in the oil filter canister. Also found some rust starting to form in the canister. Recommended adding a sludge additive. After getting customer authorization we added sludge additive to the oil tank.
Raised the ductwork to straighten the coil. The ductwork and coil will need to be properly raised and secured. There is a small kink in the liquid line also. Turned the system on, the blower turned on but the condenser did not turn on. There is a section in the thermostat wire that needs to be repaired. Opened the electrical compartment and found a snake that shorted the compressor side of the capacitor. The capacitor needs to be replaced before checking the charge. Replaced the capacitor and repaired the wire. Started and checked the charge. Discharge temp-57*f. System is operating properly. Duct Diagnostic- 203-734 -1532
Performed a spring maintenance check on a Lennox Elite XC20 air conditioner in Durham, CT. I cleaned the evaporator and condenser coils, replaced a clogged air filter, and checked the refrigerant charge using a manifold gauge set. I also tested the capacitor and contactor relay for proper function. The system is now operating at peak efficiency, ready for the warmer months ahead.
Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 6.7%o2 34 ppm co 0 smoke While performing the maintenance we found a small amount of water in the oil filter canister. Recommend getting a water and sludge additive for the oil tank
Drained the boiler and disconnect the piping to the coil. Replaced the coil/gasket, reconnect the piping and fill the boiler. Purge and tested.
The hot water coil on the customer’s boiler is leaking. Currently here is no active leak but there is sediment buildup showing there was a leak in the past. Took pictures of the boiler model and serial as well as the water coil and surrounding piping. Will email an estimate to replace the gasket for the coil and an estimate to replace the water coil and the gasket.
Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 8.5%o2 25ppm co 0 smoke Noticed higher than normal levels of sludge. Recommend getting oil sludge additive. Also found high levels of corrosion around the domestic water coil. Boiler is from 2000. Recommend replacing the boiler in the near future. Customer stated they heard air in the 2nd floor zone. Bled 2nd floor zone until all air was out. Started and tested the heat. Had hot water coming back to the return. When leaving boiler pressure was
Drained boiler and zones of all water. Cut and removed the boiler, zone valves, flue pipe, and nearby piping. Installed new Weil McLain boiler, 3 circulator pumps, flue pipe, and zone panel. Reconnected the intake air kit and oil line. Filled system with water. Purged all zones. Started and tested the system.
Shut water off and replaced the mixing valve. Turned the water back on and checked for leaks. Checked the temperature at the sinks. There was 111*F at the sinks but very little pressure going through the tankless coil. Recommend having the coil flushed.
Customer turned the system. Checked the condenser, both the condenser fan and compressor were running. The compressor was drawing 13.7 amps and rated for 19.2 amps. Checked the pressures. 41/255 psi. The suction temp was 77*. Checked the evap coil. 1/2 - 3/4 of the coil was frosting over. There is a freeze protection clipped to the suction line outside of the air handler. With the difference in pressures and coil frosting, it indicates that there is a restriction. The system is R22, recommend replacing the system vs replacing the evap coil.
Upon arrival unit was off. Turned unit on and the indoor unit and the compressor started but the condenser fan did not. Checked the capacitor and found the fan side was open internally and was not sending power to the fan to start it. After getting customer authorization we replaced the capacitor. Started the unit and found the unit was low on refrigerant. After getting customer authorization we added 1 lb R410A to the system bringing the subcooling from 3 up to 14. Went over the evap coil and condenser coil with a UV light and found UV dye in the drain pan of the evap coil meaning the evap coil is leaking. Recommend replacing the unit. The evap coil is from 2002 and the condenser is from 2017. While testing the condenser we checked the amp levels to check the compressor’s condition. The compressor was pulling 8.2 amps out of a max of 12.8 which is very high for a unit that is 7 years old.
