Fair price.




Review of Supreme Service Today

Price quoted by tech to unclog a condensation pipe was unreasonable and not consistent with industry pricing. But was able to negotiate a more reasonable price with supervisor after reviewing charges.

Good estimate, bad scheduling




Review of Supreme Service Today

I was scheduled for a noon-4pm appointment, but the tech didn't show until 6:30pm. He was professional and provided a good estimate while there but I didn't appreciate waiting around so long.

I ran unit in cooling mode. I checked electrical wiring and system. I cleaned condensation drain line and trap. It was a lot of sludge in the lines. Unit has a hard start kit already installed unit is operating at normal capacity this equipment is eight years old. I recommended to customer to get indoor outdoor coils clean. Due to sludge buildup in condensation drain also did a courtesy check of hot water heater no corrosion no signs of leaking everything is good. Also recommend service for texting so house check airflow delta T 59 return 72

Upon arrival I was told that unit wasn’t running at all. During diagnostics I found system locked out on RPM/Airflow fault. Found lockout condition doesn’t send voltage so I couldn’t diagnose without resetting system. Once system reset, blower motor came on and was running at fan only speed. Waited until compressor delay was off then ran ac, fan increased speed and then again for 2nd stage. Measured delta air temps and checked every register. Found no airflow restrictions, filter and coil are clean. Checked return and supplies and found no issues. Delta air temp at Evap coil is 24 degrees. Suspecting intermittent faults with blower motor, quoting customer to replace. Customer declined at this time, will monitor the system and let us know.

I checked in and out with store manager and BAS. I went on the roof and found a leg of the power had voltage but it was dropping voltage. I removed the cover to the disconnect panel and found where the disconnect had burnt. I turned power off, even though the phase monitor was keeping the unit from operating. I took a picture of the part. I made a part estimate form and a quote sheet. I looked the part up with the numbers provided and it is easy to find. The office needs to finalize the quote ASAP and submit to corporate for approval. RTU #2 is not operational.

Upon my arrival I noticed the house has 3 zones. I checked the operation of the zone damper on zone 3, the one in question. I found proper air flow out of one vent in each room, and realized that the other floor vent in each room was a return air duct as there was no air pushing out. I also confirmed this with a visual inspection. The package unit was cooling with 20+ degree delta temperatures across the evaporator coils. Customer replaces the filter normally. I checked the electrical wiring and electrical systems, for potential problems and found the run capacitor was 35% depleted and that the ground loop needed pressure. Customer signed up for service membership, but I did not do a maintenance but I did pressurize the ground loop to 65psi. I replaced the 45uf run capacitor and tested the unit again. Unit operating normal. Customer has the 2 maintenances to schedule. Customer wanted to put the membership payment on a separate card so I have that information on the paperwork to turn

Upon arrival I spoke with Manager Mark and he informed me that back office area was hot the other day but system was reset and has been operating normally since. Called Property Management company and spoke with Vanessa, I checked in with her and she transferred me to Phillip with the BAS system. Per Phillip, RTU 8 was the unit with problems the other day but is currently satisfied. He overrode the unit and called for ac. We checked operation and found no problems. He then asked me to find remote indoor sensor and checked temperature. Found indoor temp at sensor reading 69.6 degrees, setpoint for 70 and unit currently at 70. Phillip said all other units are either satisfied or close to satisfying. He told me to inform manager that unit is operating normal and for him to call back if indoor temp rises again.

Upon arrival found auxiliary pan completely rusted out and leaking water through roof, drain lines do not have downward slope and have hard 90s instead of a trap, quoted customer for total rehab of condensate system. AC system is at least 15 years old. Advised customer think about new system instead of costly repair to replace system. Wants to talk to salesman about pricing.

I replaced the electronic expansion valve and bi flow filter drier. I pressurized the system to 250psi and let hold that pressure for ten minutes. I then used that nitrogen to flush the lineset from high to low. I installed all new valve stems and then pulled the system into <500 micron vacuum and charged to factory specification with new r410a refrigerant, 8lb 4oz. I tested the units operation. Normal refrigerant pressures and 20+ degree delta temperatures across the evaporator coil. Customer paid balance of the repair.
