Completed heat tune up for 110,000 BTU natural gas furnace: Replaced Aprilaire 413 filter Inspected burners, heat exchanger, inducer assembly Cleaned flame sensor and verified flame rectification circuit Ignitor in good condition, measured ohm reading Confirmed proper gas pressures Cleared EZ trap, inspected drains and pump Inspected wiring, controls and fan speed setting; this unit is set to ramp up from first to second stage heating after 12 minutes; left estimate for blower motor surge protector Combustion and draft tests: Pass System operating well at this time. Homeowners paid for filter replacement today.

Completed PECO heat tune up. Equipment is 4 Ton Daikin inverter with 15KW electric Heat auxiliary. Daikin 1 plus thermostat 20x25x1 electrostatic filter in good condition. Filter rack also accommodates 20x25x4 filters Inspected wiring and controls. Measured amp draw I and verified wire sizing and breaker size of 15 KW electric heat 63A w blower: Good. Left estimate for surge protector for indoor blower motor. Also left estimate for Rectorseal power monitoring for the outdoor equipment circuit Indoor and outdoor coils in good condition Inspected drains. There is an EZ trap. Drain piped to sump. There is no wet switch. Left email estimate. Measured temperature rise (66-100) and static pressure Did not put gauges on system because air temperature rise was perfect and this equipment is considered critically charged. Putting gauges to check pressures not necessary unless a performance problem occurs. System operating well at this time. Left estimate for VIP Heat pump plan member

Taped the underside of return drop where it meets furnace and box. The tiny gap there is what Was causing the whistling sound. The popping sound was caused by the expansion and contraction that happens in ductwork box under furnace when fan ramps up and then gradually ramps down to off. I took blower access door off and added a stiffener/support to duct box under furnace to give it support. Ductwork no longer pops when fan ramps up to speed or ramps down to off. Second floor furnace was not making the popping sound. Set both furnace heating fan speeds to MED LO or target 1620 CFM in second stage heat (1280;in first stage) based on blower performance chart. There was also a MERV 13 filter. I recommend using MERV 8; but definitely no higher than MERV 11. SystemS operating well at this time.

I provided a proposal for Zach took measurements of the entire house and went over the entire workscope with the customer. Customer stated that they don’t want to move forward at this time but to follow up sometime around mid December.

Completed (2) heat tune ups: Both systems in basement 1st floor 90,000 BTU nat. Gas furnace 2nd Floor 70,000 BTU nat. Gas furnace 20x25x1 filter in good condition Replaced 16x25x1 filter For EACH furnace: Inspected burners, heat exchanger, inducer assembly, pressure switches Cleaned flame sensor, verified flame rectification circuit Inspected ignitor, measured ohm value Confirmed manifold gas pressures Inspected drains, pumps on good condition Measured temperature rise and static pressure Combustion and draft tests: Pass Completed (2) Humidifier services. Replaced (2) 45 water panels. Opened water feed valves to provide proper flow. Opened bypass dampers. Tested operations. Target humidity is set/controlled at thermostats. Both systems operating well at this time. Homeowner paid balance today.

Upon arrival for heat pump I changed the filter. I checked blower motor and assembly. Checked em heat kit and electrical. Inspected coils. Evap coil is in bad shape. Checked air temperature rise and it was only 15°. Proceeded outside and checked all electrical. Checked fan motor and assembly. Checked refrigerant pressures and they were low. Found evap coil leaking. Recommend replacing air handler.

Completed quality assurance for AC+ Gas furnace installation Inspected all aspects of install; equipment, mechanical, drain, wiring, vent piping, ductwork connections Verified fan speeds and control board setting Measured temperature rise in both stages of heating and temperature split in AC. Checked refrigerant charge. Verified proper gas pressures in low and high fire operation. Combustion and draft tests for both furnaces: Pass Install passes quality assurance.

Completed Quality assurance for 1st floor system: AC and Gas furnace. Filter size 16x25x1 Inspected all aspect of install: mechanical, drain, wiring, vent piping, ductwork connections. Verified proper fan speeds and control settings. Verified refrigerant charge. Checked gas pressures in low and hi fire heating. Measured temperature split in cooling, temperature rise in both stages of gas heating. Leaked checked gas piping. Install passes quality assurance inspection.

The cause of thermostat going blank was an open safety. EZ trap opened due to a small clog in drain line. I used brush to clean drain line. Showed homeowner how to clear drain/trap. Tested and flushed drain with water. Checked system operations: Good. System operating well at this time.

Installed new trans gas furnace and A/C outdoor unit. Reused return and built new supply. Tapped/ caulked return and supply. Adapted high volt and installed new outlet and switch with surge protector. Ran new condensate line with ez trap and condensate pump. Adapted gas line and flues. Installed new honey well thermostat and wired up low volt with safeties. Ran new line set with thermostat wire and piped into new equipment. Installed new outdoor unit on leveled pad. Installed new disconnect with surge protector and wired into outdoor unit. Cleaned up work area and tested out equipment.
