Inspected wiring, controls, electric motors and components. 20KW electric heat amp draw 85A ok. Thermostat cannot be configured to control electric auxiliary heat us. Provided email estimate for WiFi thermostat which will result in savings. Told him he can leave the top breaker on the service disconnect at indoor equipment off to downsize the heat kit to 10KW. If he feels uncomfortable he will turn back on. Measured temperature rise and static pressure Inspected drains. There is no trap or overfill protection switch on drain line. Provided estimate for EZ trap. Also provided estimate for wet switch/flood safety Verified integrity of compressor and defrost cycle ok. Checked refrigerant charge/pressures. R22 198/36 ok. Heat pump operating ok at this time, but is well beyond Replacement age. Also lacks control of

Performed precision heat pump tune up on 2021 amana heat pump system. Replaced aprilaire 213 air filter, provided by homeowner. Checked all electrical connections and components. Checked temperature rise. Tested emergency heat. Checked refrigerant pressures and temperature and indoor and outdoor units. Provided estimate to install uv bulb to kill any bacteria on evaporator coil. Heat pump is working properly at time of service.

Luis 2-10-26 performed gas heat tune on 2011 Ruud gas heater 90%. Check all electrical low and high ok. Replace customer supplied 413 filter. Check ignition components, air delivery motor and wheel, inspect combustion removal system. Performed combustion test ok. Temperature rise ok. I noticed burners and sensor had some rust. I cleaned them as much as possible. Heat exchanger is showing wear. Unit is 15 years old. I provided estimate to replace burners, sensor and igniter, Would recommend getting an estimate for replacement of system. Unit is over life expectancy, all parts are original to system, system is operating properly at the time of service.

Customer called in for no heat, oil boiler. System, has four zones. Three zones are working. Number two, which is kitchen, dining room, living room entertainment area. I tested valve ok. Both sides of valve are hot, I noticed no water is flowing back to boiler from that zone. all other zones have plenty of water coming back. Could be restriction or frozen pipe. Customer will need to contact plumber for this issue. I also purger is leaking I added cap for now this should also be fix.

The pressure trannsducer will be replaced in accordance with Bosch bulletin using a tee and installing the transducer outside of the cabinet. Rewire the unit and test operation. Part is listed as under warranty., Complete warranty paperwork and return with vendor. 2/6/26 Installed new pressure transducer at outdoor service port using 1/4” SAE swivel tee. Flared the 1/4” inducer tubing. Used a flare tire fitting/gasket here. Tightened all tee firings. Checked for leaks using soap bubbles. Ran new wire to control. Ran system 20 min with probes on. Compared measured liquid pressure to liquid pressure recognized by the control. 304 measured pressure 308 on control: Good Also followed Bosch procedures and checked Volts DC between two points on the connector. Found to be good. System operating well at this time. Collected payment.

I arrived to the customers home to look at his Bosch heat pump system. The system is 3 years old, and it’s a second homeowner from this was installed. I found that I had the same lockout code on the outdoor unit H5. I did reset the unit and go through my testing process to see what is going on with the heat pump system. I started up in the attic to be sure. The air filter was OK. Air filter size is 20 x 22 x1. My Gauges I have 55 psi and 265psi. Board - 72psi / 14 psi I ran a test on my transducer and it failed I have 5 dc volts which it needs but my pressure ratio needs to be 0- 4.0 I have 222.6 . Transducer is failed. No charge for today recall . Management will reach out to the customer to see if there is any kind of warranty on the part and the pricing and availability on the transducer.

1/28/26 Dan I arrived to the customers home that the furnace isn’t running. Found the gas Weil McLain boiler not heating. I have a call from the thermostat and the circulator is running, found the pilot light was out the thermocouple isn’t holding the flame. I quoted for new thermocouple , and talked to the customer and had told him that it could also be the gas valve not holding the flame. He went ahead and approved the thermocouple repair. I replaced the thermocouple and it held the flame. I tested for combustion and it passed. I Did highly recommend to the customer that the boiler should be replaced in the near future . It’s 28 yrs old . I collected for diagnostic and repair for $483.18 paid by cc. I did leave an estimate for a boiler contract for the customers to review.

Found outdoor unit locked out on H5 error code. 5 low pressure lockouts in 100 min. I enabled the extended defrost dipswitches at outdoor unit, this will allow defrost to run 60 seconds longer to help with returning outdoor coil to a state where it can act as heat pump Checked filter. It is clean. The correct size filter for this air handler is a 20x22x1. He has been using the 20x20x1. Afterwards tested system. Had probes on refrigerant ports. Lowest the suction pressure got was 54 psi. Not low enough for a low pressure incident. Temperature rise after 15 mi. Was 70-105 or 35° Good There is no supplemental electric heat kit in air handler so during defrost they will feel cold air from supply ducts/vents. There is some snow inside outdoor unit. We poured hot water on sections of piping at outdoor unit that were covered in snow. It is better to assess refrigerant charge on the cooling season. System operating well at this time. There is an oil boiler with (3) zones. There is a le

Homeowner’s carbon monoxide detector went off late last night. He was using his wood fired fire place in living room. I did an ambient carbon monoxide search throughout the house. Also did ambient Carbon monoxide test in the ductwork of each system while running 0 ppm million, Combustion analysis/test for each furnace: Pass The only time where I had a brief blip of 1 ppm but it quickly zeroed out. was when I was within 5’ of wood burning fireplace. Chances are the CO detector malfunctioned last night. Also replaced the 20x25x5 filter at basement system. It is a MERV 16 filter so replace every 3 months. His detectors are 12+ years old. I offered a low level carbon monoxide alarm. He is going to replace them.
