Injected leak detection dye. Will help us find leaks later. Used superheat method to accurately charge system 3 Ton heat pump. Needed 30oz R410A. Final pressures 267/116 15.5S°SH 1.7°SC Final temperature split 18.5° (75.8-57.2) System will operate well until enough refrigerant leaks out that it becomes problematic again. Total system charge is 10# So the amount added today is 1/5th of charge. Left estimate to replace condensate pump and vinyl tubing. Equipment dates to 2013.

Fully assessed no cooling situation. Found Luxaire heat pump pretty low on charge. 410a refrigerant pressures were 294/99 with 55 superheat. Provided estimate to add refrigerant and dye but highly didn’t recommend it because it could jut leak back out, better of putting money to replacement of heat pump system. Homeowner would like to talk to his wife first before setting up a consultation. A/c is barely working at this time.

Perform precision AC tuneup on amana AC system. Replaced dirty Aprilaire 413 air filter. Checked all electrical connections and components. Checked temperature split. Cleaned out ez trap. Found no surge protection for Ecm motor, provided estimate. Found outside coil dirty thoroughly cleaned outside coil. Tested outdoor capacitor, checked refrigerant pressures and temperatures at indoor and outdoor units. A/c is working properly at time of service.

Check the wiring connections and the voltages. Checked the pressure gauge and the temperature gauge and looked and inspected for any water leaks. Inspected the heat exchanger and inspected the igniter. Inspected the water trap and tested, and inspected the condensate pump. I tested the unit for combustion and checked the zones for good heat from the supply back to the return . Everything is working fine at this time. Checked the AC side of the system . Checked the air filter and found good . Checked the wiring connections and the voltages on high volt and low volt. Inspected the indoor coil and flushed and tested the drain line. Checked the blower condition and inspected the blower amps and tested for static pressure. Went to the outdoor unit and inspected the wiring connections and the components . Checked and tested the pressures by using superheat and sub cooling methods. Checked the amps for the compressor and the fan motor and checked the indoor cooling temps at the supply an

Performed Tune up on Amana gas furnace, checked combustion and gas pressure. Tested blower and inducer motor and cleaned and checked flame sensor and tested burners and heat exchanger. No issues with furnace at this time.water heater is from 2014 and should be replaced before a leak becomes an issue. An estimate was created for replacement.

Completed 6 month inspection for Trane heat pump. 14x30x1 filter ok; left one for them. Inspected wiring, controls, electric motors, thermostat configuration Tested electric heat. 15KW 60A Good Ran system in heat test mode about 20 minutes and assessed system performance Pressures 68/359 temperature rise 24°(69-94) outdoor temperature 30°. Checked defrost cycle System operating well at this time.

The 2 wire between the problem thermostat was knicked. There was no continuity. I pulled wire from behind trim and found the Knick. Was almost a complete break. Because there was plenty of wire to work with I pulled some up and tested continuity. No other breaks. Homeowner will mount thermostat now that the break is gone. The (2) circulators are controlled using outdated methods. May be a good idea to install 2 zone boiler relay. Tested system operations. Good At the end of my time here the display on the thermostat they had bough went blank. I left estimate for T4 heat only thermostat. Combustion and draft tests pass. Charged for wiring repair.

Customer installed nest thermostat on 2 wire system that goes to aquastat so the nest has no way to charge itself and once it dies the zone it’s connected to has no heat. Customer stated she will go get and install thermostat herself. Removed nest for customer

Formed quality assurance on recently installed train communicating heat pump system. Checked over all the electrical wiring and connections. Checked refrigerant pressures and temperatures at indoor and outdoor unit. Checked overall penetrations. Tested condensate drain with water checked over all the settings in Trane Link thermostat and made sure everything was correct. Talk to customer about any concerns or problems. System is working fine at quality assurance.
