Fall pm On 02/18/19 On arrival set unit to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced units operating normal at this time.
Upon arrival I found furnace wasnâ€™t operating because condensate pump was full and cardboard safety tab wasnâ€™t removed. Removed tab and pump started running, then furnace fired up and started running. Then went to start ac and found system flashing High Side Fault, found high pressure switch wire wasnâ€™t plugged into board. Plugged in and outdoor unit started running. Finally found low voltage wiring wasnâ€™t consistent, colors changing from furnace to ac to thermostat. Made all wires consistent throughout. Tested unit afterwards. Unit is operating normal at this time. Customer also gave me paperwork to give to office for installation.
On arrival found high voltage fuse blown ,replaced it ,tested it unit operation, system operating ok .plz charge credit card on file
Customer had leak from condenasate line on tankless heater due to plastic tubing bent water was unable to drain causing it to leak out onto floor
Will return with Denny tommorow to go over the piping
BAS is closed on the weekends, I tried calling but no one is there. Manager confirmed this as well. I still trouble shot the two units. Heater #2 locked out on failure to sense 1.1 micro amps. The flame sensor needs to be replaced. Heater #3 locked out on pressure switch failing to close. The inducer motor is receiving 120 voltage but fails to operate or pull an amp draw. The inducer motor and assembly need to be replaced. I took pictures of the parts and filled out a â€œestimateâ€ part order form and made an estimate for the approximate amount of time it will take to perform these 2 repairs. Manager signed the iPad invoice and the paperwork.
Must return tommorow morning
On arrival we found outdoor unit not going into defrost mode due to a defective defrost board, we also found a bad contactor. The unit is not operating normal. Customer is calling home insurance for repair.
Upon arrival I found NEST thermostat didnâ€™t have any power. Went to furnace and found LEDs lit, furnace not running, and condensate pump running. Found vinyl tubing was routed outside and is frozen. Moved tubing to sump pump in basement. Tested condensate pump multiple times. Returned power to furnace and checked operation. Furnace operating normal. Suggest customer replace 20x20x1 filter soon.
I checked in with the store manager and then set the ladder behind the store. I replaced all units filters and dated them. The belts for units 1-6 were replaced in late September 2018. I checked to make sure the tension was holding tight and condition of the belts. No belts were replaced as they are in very good condition. I operated units 1-6 on stage 1 and stage 2 heat mode. I operated units 7&8 on stage 1 heat mode. All units operated normal. No system faults displayed on terminals. Units are clean and in good working order. I checked the electrical wiring and electrical systems. I reset each disconnect as a means to test them and before leaving the roof I went around to each unit and made sure they had power, that the panels were properly secured and that the drains were clean. All units are operating normal. I checked out with the store manager and got their signature. I let them know everything was finished and to turn the alarm system back on.
Found furnace off . BGE shut down furnace due to CO2 in the home . Flue venting has cracks and holes in it . Recommend replacing to furnace and to hot water heater . Also checked heat exchanger and found 3 deep scratches in it . I could only access top right and bottom of heat exchanger. Due to the age ( 33 years old ) recommend replacing furnace instead of just heat exchanger . Set up time with sales come out to go over system .
