Chris was great. He was realistic and talked about how best to approach the problems we have.
I replaced all the air filters with ones provided by the customer. I pressurized the ground loop to 65psi. I checked the electrical wiring and electrical systems, including the auxiliary heat strips, all are within specification. I operated the units on second stage heating mode and recorded 25+ degrees temperature rise across the air coils. I calculated and recorded actual heat of extraction for each unit. All units are operating normal.
I replaced the air filters in units #1 & #3. I pressurized the ground loop to 65psi. I checked the electrical wiring and electrical systems, all are within specification. I set flow rate on the geos to 11.5gpm and calculated heat of extraction. Temperature rise is normal on all units. Auxiliary heat strips energize in sequence on all units with safety devices intact. Unit #3â€™s coil is starting to get some bacterial growth and a Uv light would eliminate it and prevent future growth. Also all units need to have EZ Traps installed to prevent flooding. The humidifier drains can be piped after the EZ Trap so that it would be protected in heating and cooling seasons.
Busted up concrete and drilled holes in foundation for bathroom kind of in the seller way went over plans with Dave The new plans still show waterlines coming out of the ceiling and are not drawn right
Unit #1 was not operating due to a low pressure fault and auxiliary heat was not working. I used electronic leak detector to find the leak on the high pressure side service valve, in the tubing, where a stress fracture formed. I brazed it with heavy brazing and flushed with dry nitrogen and pressurized the system to 300psi. There are no other leaks and the leak was fixed. I pulled into a <500 micron vacuum and charged with r427a refrigerant and marked the unit as such. I replaced the auxiliary heat voltage distribution system so that the customer has the ability to use it if a problem occurred with the geo heat pump heating. I checked the capacitor and it is within specification and all other electrical is in good condition. Unit operating normal.
Roughing in the first part of the building for two story part
Fall pm on 10/30/19 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 cleaned checked compressor capacitor checked coil checked blower motor checked EWP and LWP also water temp checked all other electrical connections unit tested unit operating normal at this time highly recommended duct cleaning also uv lights installation and wet switch installation to avoid future problems.
On arrival checked thermostats were called for heating . Measured temperature coming in, temperature going out, amps, voltage, water pressure, water temperature coming in and going out, system needed to be pressurized, replaced both filters provided by customer. Inspected electrical connections, voltage absorption systems, and also I explain the benefits of the estimates that I recommended to the customer. We gave Alex a call to work on some pricing. customer is interested just got back from out of town had to pay bills. Before getting work done system and unit is operating normal at this time change filter on geothermal system customer change filter on carrier. Follow up form was completed.
Installed Some pumps and ran lines out the building advise superintendent sump pump still have mud them and will hurt pump
Outstanding Balance. 99.96
We wrapped up all items on the inspection punch out list.
Units drain line was partially clogged. Customer signed up for service membership which includes a drain cleaning. I also performed cooling maintenance as well. I checked the electrical wiring and electrical systems, all are within specification. I did clean the condensate pan and drain lines and ran water to flush the debris and to check for proper drainage without leaks. I pressurized the ground loop to 65psi. I checked heat of rejection and delta temperatures across the evaporator coil. The filter was recently replaced by the customer. Unit is operating normal. Since customer signed up for membership today I was able to waive the dispatch fee. Customer still has one maintenance left to schedule for either heating this coming winter or cooling next season.
Replace voltage absorption system, unit #3. Cube unit #3 had a failed 40uf single run capacitor. I replaced it after quoting the repair. Once power was restored I went to the air handler to confirm unit was cooling properly. Unit operating normal. Customer paid with a check and another check for a previous balance of $99. Both checks went through the mobile deposit program.
Customer not home, gave us garage code. Upon arrival we found top floor geo system locked out on low pressure/compressor monitor. Opened up panel to find Comfort Alert flashing 4 times, locked rotor fault. Checked capacitor rating and found it in spec, 38.8 rated 40. Checked compressor ohms and found them to be normal 1.2, .8, 2.1. Cleared fault by resetting power to the unit and called for ac from thermostat. Compressor came on and unit started operating normally, pulling 4.2 amps in first stage and 7.2 amps in second stage. Cycled ac multiple times and system ran perfectly every time. Didnâ€™t find a cause to fault alert but system is operating normally.
Both units #2 & #3 that I had repaired were overcharged. I removed the excess refrigerant from each circuit and then operated the units on cooling mode and I had normal refrigerant pressures, 8-12 degrees subcooling and 20 degree td. Both units are operating normal.
I put amp meter on wires and h.w.h. pulling 9 amps across both elements. I noticed the wiring was not correct and the elements were always heating at 1/4 capacity. I fixed the wiring and tested lower element, it was pulling 18 amps. I had to replace the upper element and tested it after replacing. Both elements and thermostats are pulling 18-19 amps and are working properly. I called the service manager to let them know. I took before and after pictures of the wiring.
On arrival set units to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drains and cleaned them, checked water pressure and raised it,replaced Contactor.also checked for leaks .i didn't noticed water leak .units are operating normal
On arrival set units to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned,checked water pressures,replaced filters .units operating normal
Pump down refrigerant . Repair leak on lineset and pressurize system with nitrogen and make sure it holds . Put system into a vacuum and make sure it holds . Then charge system with R410A and check operations . Suction pressure 125 , head pressure 290 . Return temp 67.8 , supply temp 46 . Suction line temp 54 degrees . System is operating properly now .
Customer asked to reschedule for earlier time Saturday or Sunday will call in with his available time and day in 30mins
On arrival checked thermostats were calling for cooling. Measured temperature coming in, temperature going out, amps, voltage, water pressure, water temperature coming in and going out, system needed to be pressurized, replaced both filters provided by customer. Inspected electrical connections, voltage absorption systems, and contactors. Customer stated that he had his duct cleaned and thermostat was not communicating after the company that performed the job left. When I set carrier unit to call for cooling found outdoor unit not coming on, reset system and unit is operating normal at this time

Spring pm on 03/25/19 On arrival set units to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced checked water pressure also checked outdoor condenser unit checked electrical connections checked voltage and amps checked coil cleaned recommended UV Lights installation units tested units operating normal at this time.
Spring pm on 03/14/19 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 recommended air filter need to be replaced also the duct has a l lot of dust duct needs to be cleaned and UV lights installation gave quote for customer needs some time to decide unit tested unit operating normal at this time.
