The filter was recently replaced. Evaporator coil and blower wheel are very clean. I cleaned the condensate pan and drain lines and ran hot water to flush the debris and to make sure it drained properly. I checked the electrical wiring and electrical systems, all are within specification. Unit cooling with 20+ delta temperatures across the evaporator coil. The condenser coil is very restricted with dirt and debris and as it heats up this summer it cou,d cause the head pressure to get too high. I recommended cleaning. The disconnect at the condenser is rusted in place. I showed the customer that it could not be worked free and the power has to be turned off from the main breaker panel. I recommended replacing the disconnect as well. Otherwise unit is operating normal with minor repairs recommended.
Installed new contactor in condenser #2. Made all wiring connections. Checked operation. Also cleaned the condenser coil on the same unit. Replace the air filters. Checked and clean drain pans and traps. Checked condensate pumps and operation. Checked wiring and connections. Checked capacitors and ratings. Checked units and thermostat operations.

Upon arrival I was told that heat wasnâ€™t keeping up on the very cold nights. During diagnostics I ran both HeatPumps and checked operation. Found no problems with HeatPumps. Ran aux heat and found hot water coils are getting supplied water, but it is cold. Found oil motor for boiler was tripped. Informed customer and she is going to call Carroll who services her oil boiler. Found no other additional problems. I also explained to customer about aux heat deadband and HeatPump lockouts programmed in thermostat. She asked if I set up the HeatPump lockout to 30 degrees since it has a tough time keeping up at below freezing temps. Carol Silver main contact.
I checked e.a.c. for cleanliness. I checked the electrical wiring and electrical systems, all are within specification. I lowered manifold gas pressure from 3.71 to 3.5 iwc. I operated the unit on heating mode and calculated cfm using the temperature rise method and found the unit is moving plenty of air so the furnace will not overheat but at the same time the temperature rise is within comfort range. I walked customer through how to replace the humidifier pad. The humidifier is working but is a much older model. I told the customer I would send an estimate to replace it with a new model Aprilaire 600 Bypass Humidifier.
Customer called because the thermostat was not displaying the outdoor temperature and the indoor unit blower was running constantly. I labeled each unit for identification purposes and then went to test mode in the thermostat and called for compressor heat stage 1 and 2 on unit #2. I found the outdoor unit not operating. I did not have power at the disconnect and found the breaker was tripped. I showed the customer which breaker was tripped. I reset the power and checked amperage draw of unit #2. It was drawing under 10 amps and the breaker was rated for 40. I found no reason to suspect any problems with the equipment and cycled the unit several times. I also checked the refrigerant pressures and they were normal.
On arrival removed old canister.i then installed new canister .tested it ,unit operating normal
