Spring Pm On 06/11/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filter and replaced checked water temp and pressure checked compressor capacitor checked all other electrical connections tested unit operating normal at this time.
The condensate pump failed to activate despite being 100% full of water. Either the motor was failing or the activation switch was failing. Either way, it was best to replace the pump. I replaced the pump, connected drain hoses and ejection hose and wired the pump into the system. I checked for proper operation. Unit operating normal.
I pumped the system down and replaced the indoor txv. I pulled the lineset into a sub 500 micron vacuum micron vacuum and opened the service valves and removed a few ounces of refrigerant to obtain 10 degrees subcooling. I adjusted superheat on the new txv and did drop the blower speed by one setting. Unit operating normal. Customer needs to replace the air filter.
Upon arrival I found condenser fan running but compressor not. Opened up panels to find run cap wire was broken and burnt, terminal it was connected to it partially blown. Replaced wire connector but compressor didnâ€™t start. Quoted customer to replace dual capacitor and she approved over the phone. Replaced and returned power to system and ran ac. Checked operation and found contactor is burnt, condenser coil dirty, and outdoor disconnect (40amp breaker) not always sending voltage. Quoting customer to replace contactor, clean condenser coil, and replace breaker but she declined.
On arrival found system not operating normal,found bad expansion valve.unit is not operating normal
On arrival checked thermostat was calling for cooling. Measured EWT,LWT,EWP,LWP,return temperature, supply temperature, amps, and voltage. Inspected electrical connections, contactor is ok, filter is clean, evaporator coil is clean, blower wheel is clean, tested condensate pump, and I also cleaned condensate drain line. Customer sighned up for service agreement, paid with a check $299.00. Unit is operating normal at this time.

I cleaned the condensate pan and drain lines and flushed with hot water to move the debris out of the tubing and to make sure that it drained properly and that the condensate pump was working properly. The filter had recently been replaced. I operated the unit on second stage cooling mode. I confirmed proper flow rate and calculated heat of rejection. I did pressurize the ground loop to 65psi. I checked the electrical wiring and electrical systems, all are within specification. Unit operating normal. Customer has Intellistart already installed inside the unit and a whole house surge protector, which is great. The only thing I noticed that could benefit the customer is a Blue Tube ultra violet light. Customer was on a business call and I could not speak to them. I prepared an estimate anyway.
Fall pm on 12/28/18 On arrival set units to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced units operating normal at this time.
I operated the unit on compressor speed 12 and found the pressure drop too high. I slowed it using axb setup to 13.5 gpm with 4.5psi pressure drop in heating at that compressor speed. Being set correctly should most certainly eliminate the â€œout of envelopeâ€ faults that had been generated. Performance was not much affected by this being incorrect but it is now fully within specification. Customer replaced the filter. I checked the electrical wiring and electrical systems, all are within specification. Loop pressure is adequate. 42,000 btu/hr heat of extraction. The unit is operating normal. There is some growth on the evaporator coil which is not restricting airflow but could be killed and further growth prevented with an ultra violet light. I spoke with the customer about a few options and will send an estimate.
Service Agreement renewal
