Fall Pm On 11/15/19 On arrival set unit to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked air filter and replaced checked compressor capacitor checked coil checked blower motor checked EWP and LWP checked water temp checked all other electrical connections tested unit operating normal at this time. Highly recommended Duct cleaning also UV lights installation and single or hole house surge protector to avoid future problems.
I replaced the air filters with ones provided by the customer. I pressurized the 2 ground loops. I checked the electrical wiring and electrical systems, including auxiliary heat strips. All are within specification except the voltage absorption system for unit #2, which was subsequently replaced. I operated the units on second stage heating mode and recorded 25-30 degrees temperature rise across the air coils for each unit and normal flow rates and heats of extraction. 4 of 4 units are operating normal and up to specification. Customer to consider adding EZ Trap to unit #3 and to having ducts cleaned once renovation is fully completed.

Upon arrival I found top floor system not keeping up. Customer also explained that water is sitting inside of drain pan, not sure if thatâ€™s normal. Found evap coil partially frozen, shut off ac and ran fan only to thaw. While coil was thawing I found Evap coil drain pan outlet needed to be clamped to floor in order to create better pitch, did so and pan is emptying normally. Once coil was thawed I put gauges on system and found low charge. Multiple repairs done recently so I checked near evap coil. Found leak right before txv. Pumped refrigerant down into condenser and repaired piping by adding more brazen, didnâ€™t need to remake joint. Pressurized with 400psi nitrogen and held, checked for additional leaks and didnâ€™t find any. Vacuumed system down to 500micron and held. Vacuum held. Added noted charge and checked operation of unit. System operating normal at this time with 22 degree delta at Evap coil. Used tape to seal doors and used insulation around sensing bulb and suction li
Return visit to put new fun motor on arrival turn off the unit from mean breaker take out the old condenser fan motor out put the new fan motor checked compressor capacitor replaced the compressor capacitor also checked electrical connections checked voltage and amps measured pressure and temp and they are ideal indicating zero leaks measured supply and return air temp unit operating normal at this time.

Up on arrival found system low on charge, performed leak search found service valve was leaking. Replaced service valve, pulled vacuum, recharged system. Tested it unit operating normal
Upon arrival we found attic system for master bedroom emergency pan was full of water, system still running. During diagnostics we removed all water from pan then opened up panels. Found debri blocking drain outlet to pvc, we also found a lot of debri in pan, causing added condensation underneath system, dripping into pan. Cleaned out inside of drain pan and then cleaned out emergency pan. Vacuumed out debri then wiped down with towels. Tested drain with new water then blew out with nitrogen. Poured more water down to test then returned power and ran ac. Checked operation and unit is operating normal. Customer also asked us to check other attic system for workout area and we found it to be clean and has a normal delta.
I started out by adding some refrigerant and leak searching the evaporator coil and found no leaks or traces of oil residue. I found the leak coming from the liquid line service valve stem which I fixed and then charged the system to operating specification and had 20 degree delta temperatures across the evaporator coil. Unit operating normal. Customer already paid half of the repair. I took a photo of the receipt they had printed. The repair has been paid in full.
Upon arrival inspected upstairs unit, found blower fan running and filter recently changed. Reinsulated txv sensing bulb to check system operation during normal operation. Found pressures low for both high and low side. System operating with 125 head pressure and 50 psi head pressure. Diagnosed as low on charge, recommend leak search and repair, customer approved repairs.
On arrival Recovered 13.25 oz from system. Removed evaporator coil, condensate pan, filter drier, and capacitor from system. Replaced with new evaporator coil, condensate pan, filter drier, and capacitor. Pressurized system with 350 psi of nitrogen, preformed leak check on repairs and no leaks. Nitrogen pressure held for 25 minutes. Vacuumed system down to 320 microns, turned off pump and vacuum held for additional 25 minutes. Charged with 78 oz of r-410a (factory charge) and started system. System operating with 275 head pressure and 125 suction pressure as well as 74.5 return air temp and 51.2 supply air temp. System operating to spec.
One of the upstairs air handlers SN# 110302256 was frozen up and needs to thaw before the reason can be diagnosed. I freed up the sensing bulb for easier testing. I had customer turn the unit off. Customer will be out of town but says workers will be here. The other 2 systems are operating normal. Customer signed but did not pay the $59 dispatch fee.
On arrival found system locked on low pressure.found system running on low pressure .found evap coil leaking .need to replace evap coil also found cap under manufacturer specs also filter is dirty and also recommended duct cleaning after construction is done . Could not get hold of customer!!!
Unit #2 was very low on refrigerant charge and the coil was freezing up causing excess water to get blown out of the pan by the blower. Unit was only cooling with 6-8 degrees. I isolated txv bulb to make sure it was operating properly and then performed electronic leak search. Leak detector picked up a leak just in the attic air alone and narrowed it to a place on the bottom row of tubing towards the blower side, in the middle of the coil. It cannot be repaired and the coil has to be replaced. Customer approved the repair. I completed a parts order form. I did charge the system so that it is operating in the meantime. Customer signed up for service membership for two geo units. I was unable to perform the maintenance today and the customer would like it if they could be done when the coil is replaced?
On arrival set thermostat to call for cooling. Measured return temperature, supply temperature, amps, and voltage. Measured EWP,LWP,EWT, and LWT. Inspected electrical connections, contactor, replaced filter provided by customer, blower wheel is clean, evaporator coil is clean, pressurized system to 65psi, cleaned condensate drain line as well as condensate drain pan. Unit is operating normal at this time.
On arrival flipped the uv light upside down.unit running normal
