Weekend service call was prompt. The tech was kind, courteous, well spoken. A part needs to be ordered, so, I have to wait to comment on the outcome.

Customer had recently replaced the air filters in the 2 Geo split systems I serviced. The filter for the Carrier heat pump is washable. I vacuumed the surface dust off it, but it is very clean anyway. I operated the 2 WF systems on second stage cooling mode and confirmed proper flow rates and heat of rejection for each system. I pressurized all the ground loops to 65psi standing pressure. I checked the electrical wiring and electrical systems, all are within specification except the compressor run caps for both WF units were well below spec. They were each replaced in #3&#4. I confirmed 18-22 delta temperatures across the evaporator coils for all 3 units serviced. The Carrier unit had electrical systems all within specification. I went around and vacuumed each drain line and flushed with hot water to check for proper drainage without leaks. All units are operating normal.

Compressor for the yoga office has open windings and needs to be replaced. Since the unit is R22 refrigerate, I recommend going to a 410A system. The yoga workout room needs the thermostat replaced. It is not working properly.

Upon arrival I was told neither system was cooling very well. Top floor system noticeably worse than bottom floor. During diagnostics I called for ac on top floor. Went to condenser and put gauges on. Found low suction pressure and normal discharge pressure, suction well below freezing and pipe severely condensating. Went to furnace in attic to find evap coil frozen solid. Needs to thaw before diagnosing. Then I went to main floor system and called for ac. Put gauges on and checked operation. Found normal operation, system with good refrigerant pressures, normal Superheat and subcool, normal delta air temps at Evap coil. System not keeping up because top floor system isn’t cooling and airflow is restricted by frozen coil. Informed customer we will need to return to further diagnose top floor ac system. She asked if we could return tomorrow. Informed office to follow up with customer.

Condenser section is operational and suction line gets cold. Employee told me the blower does not turn on and the only access to this is through the upstairs office space which is closed currently. Also the unit serves the hot yoga studio and they will not let the technician troubleshoot while a class in progress. Need to return between 8-4 to gain access to the air handler section and try to cordinate when there is not a yoga class.

Upon arrival I found water heater has high voltage but not pulling any amps and water is cold. During diagnostics I removed panels to find top element at the lowest setting and bottom element at 120. Raised temp on top element and then lowered to minimum temperature again and relay clicked over and lower element started heating. Once lower element satisfied it sent power to top relay. Measured amp draw and it is very low for top element. Removed wires and checked ohms of element to find it is bad. Had replacement element in truck so I removed water from the tank. Replaced old element with new one and tested water heater. New element pulling 18amps, lower pulling 19amps. Let top element satisfy then let bottom element satisfy. Set tank at 120. Also found Pressure Relief Valve wasn’t piped to the ground. Used 5ft of 3/4 cpvc for Pressure Relief. Unit operating normal.

Upon arrival I was told that ac wasn’t working properly, airflow needed to be address, and blinking red lights on cube need to be resolved. During diagnostics I ran ac on both zones and checked operation. Found all zone dampers are operating normal but when new damper for 2nd floor zone is opened, it steals too much air from other trunks. This damper has a maximum set screw for this reason so I spent some time balancing airflow on all floors and vents by closing maximum set screw. Airflow increased on all registers, besides addition. In short, too much air was being fed to new truck and took away from previous zones. I then found cube had low pressure/comp led lit but compressor running. Opened up panel to find Comfort Alert flashing locked rotor, even though compressor is running. Shut off transformer to clear fault then reset system. Fault never appeared and unit never came close to faulting. Put gauges on the system because I wasn’t seeing a great delta across Evap coil. Had to

The problem was my fault. There is no disconnect in the attic and I had turned the power off to the unit at the units switches. It still did not kill power to the zone board which has its own transformer and while looking into turning that off and wiring in the zone damper to the upstairs addition I forgot to turn power back on to the air handler. Customer had me come back in and adjust dampers to his sons bedroom all the way open to increase airflow back there since airflow is being lost down the additions trunk line, which is getting good airflow.

Wired in second floor addition zone damper to the existing zone board in the attic. I reloaded the first floor thermostat to new position and wired it into the eim in the garage. I sealed up one open duct in the garage temporarily. Duct fittings need to return to finish trimming and move two ducts into correct position for cabinets.
