Closed job. There were no notes added.

Issue is with the far first floor bedroom and the room immediately above it are remaining warm. There are (3) Thermostats in the building. 1st floor thermostat in the foyer/entrance controls the basement system. The other First floor thermostat (in the problem bedroom)7 on the opposite side of the building controls (2) booster fans only it does not have any control of the heating or cooling equipment. It is the second floor thermostat that controls the heating and cooling for this far first floor bedroom. So what happens is the second floor thermostat satisfies and those (2) rooms remain warm. This has not been brought to our attention because up to this point no one has used these rooms. It will not be easy to zone this from the ductwork because each supply duct will need its own damper and the tic is very tight. In fact there is an abandoned 8x8 damper. The best solution here is to install a (2) head Minisplit system. To allow for heating and cooling for these spaces. This wil

Luis 6-8-26 Performed ac tune up on two Amana systems 3 ton first floor and 2.5 second floor both units from 2017. Both 413 filters ok. Check all electrical connections and components, check drain system, air delivery and drain system, indoor and outdoor electrical components and coils, compressor and fan motor operation. Found second floor not working, (open capacitor) talked to father Jim and he approved replacement of capacitor for second floor. Check refrigerant levels and pressures for both units. Both unit registering little lower than normal numbers. I provided estimate to add refrigerant and dye. Father Jim approved adding refrigerant to both units and also add dye. After adding refrigerant and dye re test system pressures and compare before/after both units are running within manufacture standards. We will check for leaks during next visits.

Luis 3-16-26 customer called for noise, I inspect system operation. Noise is coming from return grill, I check ductwork system supply and return, air handler has a very hard to get to, final recommendation is replace duct system. Supervisor to come out and insect ductwork, this is the only way to fix issue. See notes from previous years. No charge warranty

Equipment is 4 Ton AC with 90,000 BTU 2 stage natural gas furnace. 2 zones Lennox Harmony III zone board with discharge air sensor that opens the AC (outdoor unit) circuit when temp drops below 40° (2) Zones (2) Thermostats 1st Fl and 2nd floor (3) Dampers: (2)are 8x20 1st Fl (1) is 16x8 2nd Fl Formerly the other side of Y conductor at the furnace control was landed to DS on the zone board so only when dehumidification would call would the Y contact close on the indoor control and energize cooling blower speed. Zone panel is no longer energizing the dehumidification, so o wired to Y1 contact on zone board. Afterwards tested AC. Pressures ok. Capacitor is a 45/10uF reading ok on 45 but a little weak on the 10 (fan) side. Contactor is also pitted Provided estimate to replace both. During my time here today we discussed and I recommended replacing the system. Offered consultation but she will be too busy to be able to sit down for a consultation. I took notes and photos for Joe to

Luis 2-10-26 Replace OEM Furnace Control+Flame Sensor. Set up board to match existing heater. Test heater operation ok. Performed combustion test. Heater is now working correctly. Temperature inside house went from 53 F to 60F by the time I left. Customer had to leave the home prior, finishing up office to call customer to collect balance.

Luis 2-9-26 follow up visit found unit off on ground not conneted issue. Check ground and wiring, ground is good. reset unit and unit came on. Test operation, I see lot of wear on ignition system. Heat exchanger, burners and igniter. System is 14 years old. I would recommend replacing system. Heater needs new sensor and control board.

Found furnace off. 90,000 BTU 2-stage Error code 112 “Furnace ground not detected.” Opened 4x4 box. There was a gap on the grounding wires. I Wire nutted These together however found 2x4 box that feeds furnace with an old cloth wire WITHOUT a ground. The only nearby available ground is from an outdoor lighting wiring box. I ran a 15’ length of MC wire between this box and the 4x4 box with the ground to provide a ground to the furnace. Error code still persisted. Based on Lennox troubleshooting forum. The game sensor connections can also be the source of this problem. I throughly cleaned the terminal that the wire connects to there was a decent amount of rust her put everything back together. Started system and no error codes presented themselves. We need to order control board but this isn’t guaranteed to solve problem.Left estimate to replace board and flame sensor. Strongly recommend having an electrician run a new feed wire from breaker panel to the furnace with its own gr

Added. Piece of foam insulation and taped the one side of the 14x14” return grille in their daughters bedroom. There is a slightly greater vacuum on that return now that I secured that flex better and put a clean filter in and as a result a piece of paper began vibrating in the bay. The system was set to Fan On when I left today as I had told Vien before leaving. She set Fan back to Auto. System operating well at this time.
