Mainfloor/basement unit capacitor had failed on herm causing compressor to overheat and unit not to cycle. Recommended replacement of capacitor. Cooled compressor - cycled system to check operation - performed rest of tune up service on both AC units checking all electrical components, refrigerant balance, unit start up, operation, shutdown, cleaning of indoor and outdoor units, treatment of drains. Everything looks and runs great!
Replace the condensate pump to see if that one was causing the water issue
Pump down refrigerant removed coil replaced coil and TXV. Added to metal strips on both sides of the coil to prevent any water from splashing out as the drain pan of the new coil was very shallow on the outside edge. Pulled the vacuum the 300 µm. Released refrigerant check charge. Charge system to manufacturer specs.
Returned 7/8/25 removed water from auxiliary drain pan - allowed unit to cycle on - ran water through system primary drain pan through drain - condensate pump cycles normally - blocked primary drain port and filled primary drain pan with water and watched - found drain pan drips in back left corner of primary drain - recommend replacement of drain pan - will follow up with availability of drain pan.
Water in emergency drain pan. Put my level on the air handler and it was pitched toward the back of the unit away from the drain. Main adjustment to the pads under the unit so it has pitched toward the front. Pulled the filter door off the unit and shine my light as system. Didn’t see any evidence of water dripping over the drain pan took the drain pipe out of the condensate pump and put the PVC pipe into a clear water bottle to see it drain. Filled up the water bottle pretty fast still didn’t see any evidence of water dripping past the drain pan. I think the drain pipe that went into the condensate pump went in just a little bit too far causing the PVC pipe to have a double trap. Went ahead and cut the drain pipe down so it just barely enters the compensate. Let the system run. Seems like it’s draining fine now. Double checked through the filter door one more time to verify that I couldn’t see any water dripping off the coil drain pan.
Call back - water leaking around drain pan for upstairs system - removed water from auxiliary drain pan - flushed unit drain line and treated unit condensate pump - cycled unit condensate pump to check operation of pump - everything flows and runs normally again. Cycled air conditioner to check operation of unit. Everything runs normally again!
Downstairs system breaker was tripped for heat pump. I reset the breaker and ran the system. It didn’t trip again. The main problem was the upstairs thermostat being blank. Found the emergency drain pan full of water.. Removed water and tested the system. Pump seems to be working. System has a 22° temperature difference. It’s possible that the pump float got hung up somehow or that the power surge that happened the other night may have caused an issue. I tried to look inside the return base box to see if there was water in there. I didn’t see any water in it. If it happens again, we may have to replace the pump or look further on where the water is coming from.
Today I’m troubleshooting an AC system that’s not cooling. The compressor is running, but suction pressure is extremely low. I’m confirming a restriction at the TXV inlet. Recovering refrigerant, replacing the valve, pulling a deep vacuum to below 500 microns, and recharging with R-410A to manufacturer specs. Verifying subcooling and superheat to ensure proper metering.
Today I’m working on a basement dehumidifier installation. The unit is being ducted to a central return to handle high moisture levels consistently over 65% RH. Connecting it to an external condensate pump and configuring the digital humidistat for automatic operation.
I’m on site for a filter change today. The homeowner’s 1-inch filter was completely clogged, reducing airflow and causing the coil to sweat. I’m replacing it with a pleated MERV 11 filter and reviewing proper change frequency with the customer to avoid unnecessary stress on the blower motor.
I’m performing a mini split repair today on a multi-zone system where one indoor unit is not responding. After testing voltage at the terminal block, I traced the fault to a defective communication wire between the outdoor unit and the zone board. I’ve replaced the wire and reseated all connections. Now verifying refrigerant balance across all zones and checking subcooling to ensure the system is running efficiently.
We will replace permanent split capacitor blower motor on air handler unit with a like for like replacement including the capacitor. When blower is removed from system we will also remove blower wheel and clean the blower wheel of all debris. When blower motor is replaced we will clean both indoor and outdoor coils and check system operation, refrigerant balance, and all other electrical components to ensure system is operating within manufacturer's specifications.
Replace leaking coil and txv. Will also be reworking the line set so you can get door off. Replace the evaporator coil rework copper to coil so the doors can come off to be serviced. Added 2 1/2 pounds before 10 a super heat 12 sub delta T 22.
System indoor blower motor bearings are starting to come apart which is causing a lot of vibration in the unit. Dirty indoor coils and blower wheel restricting air flow and refrigerant pressures reflect dirt coil. Recommendation is replacement of blower motor and cleaning of blower wheel as well as perform a tune up service to clean indoor and outdoor coils.
Ultimate Cooling Tune-Up: cleaned coils, brushed and cleaned traps, added pan treatment tablets to pan. tested and checked all controls, wiring connections. tested temperatures, checked filters. checked refrigerant temperature and pressures, tested static duct pressure. tested blower operation, tested cooling operation to ensure working within manufacturer specifications. Second floor unit was low on refrigerant. Added 6 pounds of refrigerant. Performed a leak search. Found leak middle of evaporator coil on right side.
