06/27/2025- I ordered the replacement parts from carrier, they are not in stock and will be shipped to carrier either Monday or Tuesday. Once the parts are delivered we can call to schedule the replacement job with the customer. 07/02/2025- I arrived on site to replace the faulty TXV and filter drier. This units warranty has expired. After installation of the new equipment I preformed a nitrogen pressure test and leak search, and have confirmed that the unit holds pressure with no leaks. I then pulled the unit in a vacuum below 500 microns before charging the unit back up with a factory charge of 410A refrigerant. All pressure and temperatures are within spec and the unit is getting good heat transfer, however I was unable to get the temperature split since the homeowner wasn’t home. We will have to rescheduled this maintenance for another time when someone is home to let us in. However the unit is working properly at the time of repairs.
