Unit was in operation when I got here. Homeowner said he had to mess with vinyl on pump this morning. I turned off unit and went to remove pump to inspect it. The safety wires immediately fell apart and wire nut fell off. They had the orange wire nuts on them and not put together well. Stripped all wires and put on blue wire nuts. Added condensate tabs as well. Wired unit back up and tested operation. Pulled on condensate wires and shook pump. No issues. Seems like it was just a loose safety wire.

Completed heat tune up for 2 ton heat pump with 10KW electric heat kit. Aprilaire 401 filter in good condition. Humidifier pad in good condition. Checked operations. Inspected wiring and controls. Verified proper amp draw of 10KW heat kit. 40A Good. Outdoor equipment has surge protection. Indoor equipment does not. Left estimate for blower motor surge protector. After discussing, homeowner agreed to estimate. I completed work and tested today. Indoor and outdoor coils clean Inspected drain and EZ trap. Measured temperature rise and static pressure Verified integrity of compressor motor. Confirmed refrigerant charge/pressures System operating well at this time. Homeowner paid for plan renewal and EXM surge protector today.

Arrived for no heat we are just here yesterday and had told the customer that he would need electrician. The Electrician apparently found no problem with their side of power . I came out to look at the equipment. I had 120 V coming to the receptacle. I checked my wire nuts and the wiring at the furnace coming in from the receptacle and had no 120 volts . I took apart the 4x4 box For the switch and receptacle and found a very loose neutral from the furnace that was barely connected and causing arcing. I Stripped the neutral wire back put new wire nuts and tighten all connections . I Turned the system back on and tested the furnace , it came back on and and started producing heat. The system is back up and running at this time of service, no charge for recall.

Work on four suspended on the ceiling Reznor heaters. Three of them were not working. Checked operation of four of them. One had bad pilot installed new thermocouple. Another one pilot was out. Cleaned tubing and pilot. Reset unit and started heater. Third one had no 115 volt power to heater. Found breaker in the off position. Once breaker was reset unit came on. Test and cycle operation ok. All heaters are in working condition. We will need to finish cleaning/tune up on #5.

Performed QA on Trane Heat Pump/Air Handler install. Reviewed installation with homeowner. She mentioned that there was a noise coming from the return register in the hallway. She also mentioned that before her old system had low airflow everywhere and now some vents have a lot of air and other are still lower. When I went into the attic I checked all of the take offs and none of the, have dampers installed to adjust/balance airflow. Also found they used R-4 Flex in the attic instead of R-8. Checked the return filter grills and the filters need to be changed. Also found she is using MERV-10 or higher filters. Let her know to not use above MERV-8 filters and to see if that stops the noise. She is going to order new filters and change herself. Filter sizes are: 12x12x1 and 12x20x. Also let her know about the dampers and the ductwork in the attic. I recommended that she have all the ductwork reinsulated and new flex duct ran with dampers installed. She said she is fine for now with how th

Upon arrival Tom told me that he had an electrician here installing a dimmer switch yesterday. I came to unit and noticed furnace had power but no led. Traced out power and neutral. Found neutral with 120v in spots and 1.8volts in other spots it is back feeding from panel. If I pull neutral off board and jump n terminal to ground unit runs. I looked in panel and furnace is still hooked up to furnace breaker correctly. Need to have the electrician return from this point.

Installed new Bosch Airhandler on existing return box, reused existing return duct and filter rack. Installed a new supply plenum with a new flex collar. Insatlled new 10 KW heat kit.

Installed new honey well t6 non Wi-Fi thermostat. Installed new Bosch heat pump on a new concrete pad, re-leveled the ground for concrete pad. Installed new disconnect box with a built in surge protector.

Took photos of equipment five Rasner suspended on the ceiling heaters and two package rooftop units gas/ac. Access to roof is from inside the building and has ladder hatch. Office to provide estimate. For service plans. Two people will be needed. Customer has forklift and cage to access hanging Heaters about 25 feet from ground.
