Landenberg, PA

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

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.
