Andrew H.
Brushed and vacuumed burner tubes Inspected and vacuumed burner, blower compartments and surrounding area Checked electrical connections and safeties Checked gas pressure Performed combustion test Inlet pressure-4.940 in.w.c. Manifold pressure-1.173 in.w.c. Cleaned electronic air filter Customer stated the ac had run even after achieving the set point. Cook temp reading at the thermostat and saw it had a 2 degree variance which is acceptable because most thermostats have a 3 degree tolerance. Checked the wires at the thermostat and made sure all wires were secure. Necked all screws and found a screw for the mercury bulb was slightly loose. Tightened the screw and the variance went to 1 degree. Recommend replacing the thermostat in the future.
Andrew H.
Turned the system off. Removed the zone dampers for the first and second floor. Installed new dampers for the first and second floor. Started and tested the system and ensured both dampers are working properly.
Larry H.
There was a pressure switch open error code when arrived. The inducer did not start. Checked the pressure switch and circuit board. Found the board had a burn mark next to a relay. The board needs to be replaced. Jumped the inducer motor to check the operation. Inducer started and pressure switch closed. The hot surface igniter did not start due to inducer relay error code.

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 5.2%o2 50ppm co 0 smoke While performing the maintenance we saw the water heater is from 2006. Water heaters typically last between 8-10 years. Recommend replacing the water heater before it leaks. While performing the combustion test we saw an increase in o2 when the blower turned on. O2 levels went from 4.6 up to 5.2. Recommend replacing the furnace in the future.

Andrew H.
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 9.5%o2 27ppm co 0 smoke While performing the maintenance we found sludge and small amounts of rust at the oil filter and the strainer. Recommend getting sludge additive. After getting customer’s authorization we added sludge additive to the oil tank. Need to have a chimney company come and clean the chimney due to a high accumulation of soot starting to back up into the flue pipe.
Andrew H.
Upon arrival unit was off. Checked the air filter and found the filter was plugged. Replaced the air filter with a company supplied one. Started the system and checked the refrigerant levels. Found the system was low on refrigerant. Also found both condenser coils were dirty which can cause the refrigerant pressures to display as higher than they actually are. Washed both condenser coils. After getting customer authorization we added 1 lb 1 oz R22 to the second floor system bringing the superheat from 48 to 24 which is within manufacturer’s specifications. Unit had a 16* temp difference between the supply and return.
Andrew H.
Brushed and vacuumed flue pipes and heat exchangers Replaced oil filters, nozzles, and strainers Checked all electrical connections and safeties Performed combustion and smoke tests Oil furnace-5.5%o2 40ppm co 0 smoke Oil Water heater- 5.2%o2 50ppm co 0 smoke While performing the combustion test on the furnace when the blower turned on we noticed an increase in o2 indicating a crack starting to form on the heat exchanger. The o2 levels went from 5.0%o2 up to 5.5%o2. Recommend replacing the furnace in the future. When starting up the furnace the blower was on a time delay. Noticed the furnace burner hesitate to ignite when the blower is already running.

Upon inspection we found the air caps had become loose and were possibly sputtering when air bubbles were let out. Tightened the air caps and did not see any leaking throughout the maintenance. Bled all zones of air. Started and tested all zones and had hot water coming back on all returns. Unit is working properly.

Upon arrival unit was turned on to fan on with cooling off at both thermostats. Tested operation of both zones. When testing the zones we pulled the zone damper from the ductwork to ensure the motors were functioning properly. When testing the zones both zone dampers remained in the open position even when both the damper light and the zone panel indicates the damper is closed. Took pictures and measurements of the zone dampers to order a replacement.
Andrew H.
Upon arrival unit was turned off. Inspected evap coil for blockage and to check the metering device. Coil looked good and there was no water buildup in the drain pan. Turned system on and the air handler turned on but the condenser did not. Had 240v at the outdoor unit but did not have 24v from the thermostat. Upon further investigation we found the thermostat wire outside had been broken. Reconnected the thermostat wire and started and tested the unit. Unit is working properly with 13* superheat which is within manufacturer’s specifications. Had 57* supply air coming out when leaving
Andrew H.
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 5.2%o2 35ppm co 0 smoke While performing the maintenance we found higher than normal levels of sludge at the oil strainer and nozzle. Recommend getting oil sludge additive to prevent future issues.
Larry H.
When arrived, found the condensate pump overflowing. The drain line for the pump was plugged. Used nitrogen to blow out the line. Plugged the pump back in and it pumped out the water quickly. The pump is operating properly. Vacuumed the water that was around the furnace.
Andrew H.
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 5.2%o2 30ppm co 0 smoke While performing the maintenance we found very high levels of sludge at the oil filter and strainer. Highly recommend getting sludge additive

Andrew H.
Upon arrival unit was off. Turned unit on and indoor unit and condenser fan turned on but no compressor. Upon further investigation we found the capacitor was very weak. It was rated 45/5 and was reading .02/3 which was causing the compressor to not turn on. Replaced the capacitor and rinsed the condenser coil. Started the unit and checked the refrigerant levels. We found the system was slightly low on refrigerant. After getting customer authorization we added 9 oz R410A to the system bringing the subcooling from 2 up to 12.4 which is within manufacturer’s specifications. Unit is working properly with 49* supply air.

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 7.9%o2 35ppm co 0 smoke
