Landenberg, PA

*History of this system. Was originally a 5 ton Gibson heat pump. A friend of the homeowner Replaced with a 3.5 ton Goodman heat pump in April 2022 BUT they kept the original 5 ton Gibson air handler. PECO is having billing issues and has not sent her a bill for a few months so she has nothing to go off as far as energy use. She does have Ecobee smart thermostat. The heating temperature rise from heat pump is 16.5° which is a little low The cooling temperature split is 19° Good I lowered heating fan speed tap from MED LO to LOW. This improved temperature rise by a little but not much (17°) Cooling refrigerant pressures ok 108/164 11 SH 4 SC outdoor temperature 48° Ok Could not find a leak but the indoor coil does have corrosion. An inverter heat pump would give better heating performance, I took all relevant measurements to be able to replace the system. It is unlikely that we will be able to get a 410A air handler. Completed tune up procedures: cleared drain, tested pump R

Completed heat tune up for natural gas furnace. Replaced 16x25x1 filter Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses Inspected hot surface ignitor and verified resistance with meter Cleaned flame sensor and verified flame rectification circuit Measured temperature rise and static pressure Checked wiring, controls, electric motors and components; there are no surge protectors; left estimate for a surge protector for indoor blower motor and for outdoor equipment circuit Checked manifold gas pressure Inspected drain and pump. Combustion, draft and smoke tests: Pass Gas furnace is operating well at this time.

Already complete: -BD in -Baffles -duct wrap -bath fan - attic duct seal -flooring removal Need to finish: -attic air seal -measure markers -blow in - basement/closet duct seal -floor dam -BD out

Performed peco heat pump tune up. Check electrical low and high ok filter test back up heat 20 kw ok. Check supply and return air flow ok. Inspect coils indoor and outdoor. Check refrigerant levels capacitor and contactor ok. Test defrost ok. Attic unit does not have water protection, there some bacteria inside air handler, lights dim the compressor comes on. Attic ductwork has a lot of air leakage and it seems to be not insulated. Provided estimate for all the items that were discussed on today’s visit. Office to follow up with customer.

Equipment is 3 ton Heat pump with 10KW electric heat kit 20x25x4 filter just replaced System is completely flat of refrigerant. Left estimate to do nitrogen leak search. No signs of obvious leaks. No oil in evaporator pan. The evaporator drain is not piped in at all. Needs a trap and pump as well as receptacle and wire (can use breaker 7 old furnace circuit need to change breaker to 15A tan handle). Whoever installed system ran vinyl tubing to outside. Office to approve. I noticed that one element of electric heat was left detached so the heat kit was operating at half capacity. The elements measured correct ohms. Verified proper wire and breaker size (6 AWG and 50A). I Wired the other element back in and tested. Ok 40A. The temperature rise with full capacity 25°. At half capacity (the way I found it)temp rise was 17°. I would leave it at full capacity until the heat pump is fixed especially in these cold temperatures. Homeowner agreed to leak search. Found 1 leak at outdoor li

Completed 6 month inspection for 100,000 BTU natural gas furnace: Aprilaire 413 filter Good Inspected all aspects of install. Checked heat exchanger, inducer, pressure switches Cleaned flame sensor and verified flame rectification circuit Measured ignitor ohms: Good Inspected wiring, controls, electric motors. Heating fan speed set to (ArF 1620) Checked for gas leaks on piping from shutoff valve to furnace Confirmed proper manifold gas pressures. Combustion and draft tests: Pass System operating well at this time.

Completed (2) Six month inspections Replaced both filters (2) 16x25x1; Use MERV filters recommend replacing every 3 months. Will need a 1/4” nut driver to take screws out to replace filters; there’s a link to shop for filters @ dibiasehvac.com Inspected all aspects of install. Checked burners, heat exchanger, inducer assemblies Cleaned flame sensors, verified flame rectification Measured ignitor ohm values Confirmed proper manifold gas pressures Inspected wiring, controls, verified fan speeds Measured temperature rise and static pressure Combustion and draft tests: Pass Both systems operating well at this time. Discussed plan memberships. Left estimates.

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
