Performed inspection on both units. Cleaned filters. Checked cleanliness of blowers and coils. Checked electrical components. Ran aux heat and HeatPump heat. Also ran ac shortly. Checked amp draw of compressors, od fans, and blowers. Tried to run defrost but it’s too warm outside to do so. Let systems satisfy thermostats. Units operating normal.

Performed Inspection on all RTUs. Replaced filters. Flushed out drains. Inspected cleanliness of blowers and coils. Checked capacitors and contactors. Tightened electrical connections. Inspected heat exchangers. Systems were in ac mode so I checked operation and made sure thermostat satisfied. Only issue is with smoke alarm for top floor system. Customer has been told to contact Fireline for this.

Upon arrival I was told that top floor ac wasn’t working and thermostat not displaying current temp. Found thermostat giving E1 and E2 faults, ac fault and heat fault. Went to unit on roof and found no faults at all. Normal voltage going to unit and thermostat. Found no voltage returning from smoke detector, wired on terminals 24v(red) and EStop(White) jumped out terminals and system started up, thermostat faults gone. Set up ladder to find smoke detector in supply is in fault condition and won’t reset. Since it is wired to the building automation system I cannot touch it, customer needs to call Fireline. Smoke detector is disconnected at unit, once repaired we just need to reconnect wires to 24v and EStop.

Replace Warranty TXV and filter drier, recharge with new refrigerant. Upon arrival I started by removing all refrigerant from the system. Used torch to remove old txv from unit but had to cut out equalizer tube because torch wasn’t taking around black coil insulator covering pipe. Sanded down each end and used copper coupling for equalizer. Used torch to braze in new TXV and close equalizer coupling. Blew nitrogen through system while doing so and kept TXV covered and away from heat. Pressurized System to 350psi nitrogen and held while I insulated suction piping and sensing bulb. Pressure held, no leaks. Removed nitrogen and vacuumed system down to 500micron and held. Put panels back on doors while vacuum held, no leaks. Added factory charge of 55oz to system then restarted And ran AC. Total charge 70oz of 410a. Matched Superheat and subcool with spec sheet, normal compressor amp draw, normal delta air temps, normal loop heat rejection. Unit operating normal at this time.

Upon arrival I found thermostat reading 73, set for 73. Lowered temp to 70 and checked operation. WSHP is running normally but found previous fault for low pressure. Checked filters and they are extremely dirty, removed them and continued to check operation. Found no issues with unit, other than filters needing to be replaced. System uses fresh air duct that pulls in outdoor air, with filters being so dirty, Return was forced to pull more air from outside. Because today is only 75, unit didn’t have any issues running. Called office and they told me to go pick up filters and return to install. Went to Lowe’s and picked up (2) 20x20x1 filters, returned and replaced them. Unit is operating normal.

Upon arrival I found system set for 75 and currently at 75. Dropped temp to 70 so system would run in 2nd stage. Found low delta but normal refrigerant pressures. Measured Superheat and subcool and found them to be relatively normal but I had low heat rejection on the loop. Suspecting txv to be an issue so I removed bulb and stuck it in hot water, no change in refrigerant pressures or temps. Put bulb back onto pipe and has no change in operation. Called Water Furnace and spoke to Dave. He confirmed my suspicion that the TXV is not metering and needs to be replaced. Part number TXV 33P609-01, Filter drier 36P500B01, WF case number 508976. Quoting customer to replace, unit under warranty until Dec 2020. Customer approved repair and would like first call when part is replaced if possible since contractors on site leave at 3.

Compressor starts up but does not pump the refrigerant and operates 15-30 seconds before turning off, most likely on internal overload. The compressor has to be replaced along with the filter drier inside the condenser. I took pictures of the unit and compressor data plate and transferred the information onto a “part order form.” I completed a “follow up” form to alert the office to contact the customer as soon as the compressor is available. Customer has no ac upstairs which is where the bedrooms are located. I pulled the disconnect outside to keep it from trying to operate. Unit not operating normal. I called the installation manager to let them know the situation as well.

Upon arrival found tub clogged. Will perform a bio clean within drain and test drain when done. Declined walk around due to her selling the house soon and will call back in to schedule a review before her inspection. Upon further review found stopper also clogging the drain. So I eliminated the stopper and bio cleaned and system is working once again.

When I arrived I checked thermostat I checked air handler and then I checked the outside unit. the unit had a fault of a lock rotor I reset thermostat. So then 5mins later unit started up the compressor kicked on and off seconds at a time. I connected my clamp meter is reading 64-68Amps and would not continue to run, Just the fan motor only. I open caps to see if valves were close they were all open but I noticed the low pressure valve was bubbling with oil.... pictures was taking of unit and data plate. This unit has a bad compressor with one leaky valve low pressure side.

I cycled the outdoor unit on the roof several times from the thermostat and it operates each time with normal operating pressures. The air handler was inaccessible because the upstairs office occupants were not there despite me arriving at 2:30. I confirmed 58 degree supply temperatures. I set the thermostat to “hold” and showed the customer. Perhaps there was some scheduling conflicts that will be overridden now and the unit should hold the set point.
