Replace and install kitchen sink bracket

We were informed our builder did not install our kitchen sink according to proper code. The original bracket that was installed is not secure and needs to be restructured to properly align the kitchen sink within the countertop. This is the reason our sink fell through the countertop. The Supreme Air plumber was able to identify the the discrepancies with enough information for us to return to the home builder to make the adjustments.

Colin was very knowledgeable, diagnosed the problem. Also is making Supreme Air management aware that new units installed during the winter should have courtesy coolant level check prior to the warm weather.

These guys are on point.

completely trust worthy. I had a blocked filter, completely my fault, if your AC cant draw what it does is create a big block of ice inside the unit. These guys showed. Guy #1 said - 'hang on let's let it thaw' - guy #2 showed up and said - 'it's thawed, it's working fine, replace your filter, Ive been here for three hours but I'm marking you down for ONE.' Unreal. He watched out for my cats so they didnt go in the crawl space. Friendly, honest, explained every step, well-organized with their shop, explained every one of their (VERY LOW) expenses. They are ON POINT. Hire them.

Upon arrival I was shown to indoor and outdoor units. Found HeatPump not rejecting much heat so I put gauges on and found very low suction and normal discharge. Shut off unit and inspected indoor coil to find TXV frozen. Left system off for a few minutes to let it thaw. Ran ac again and found high Superheat and low subcool. Added a few ounces of 410a and high pressure increased over 60psi in 10 minutes. TXV is not regulating refrigerant and needs to be replaced. Quoted customer and he called Home Warranty Company, I gave them information on equipment and cost for repair. Warranty Company declined repair and they said they would have to send their own tech out to confirm diagnosis because a repair cost that high needs to be done by their technician.

Upon arrival I customer addressed concern over units #2, #5, #5 & #6. 1 of the 4 was operating normal. 3 of the 4 needed repairs. All repairs were completed. I did have to leave and go to the electrical supply house and RE Michael. I summarized what was done on each unit. RTU #5: Customer addressed concern about this unit. I found it to be cooling with 20+ degree delta temperatures across the evaporator coil. Unit operating normal. Due to 3 of the systems not operating it gave the appearance that this unit was not cooling as well. With all units cooling it will resume normal operation. RTU #6: I added 2lb of r427a to the right side compressor. The left side compressor had normal characteristics. Unit operating normal. RTU #2: I replaced, 208 volt primary to 24 volt secondary (75va) transformer. Unit operating normal. RTU #4: I replaced outdoor fan motor for circuit #1. I replaced the 7.5uf run capacitor. I replaced 2) HCLR 10amp fuses that were blown as a result of the failed outd

Upon arrival I found all 3 thermostats set for 72, and all 3 currently at 72 and satisfied. Put all thermostats down to 70 and went to roof. Found all 3 have a delta air temp around 20-22 degrees, normal. Opened up economizer Panels to find none of the units pulling in fresh outdoor air, normal because it is too hot for free cooling. Found front lobby unit had loose economizer wire and I found system was periodically cycling fresh air free cooling. Once I connected wire back the fresh air damper stayed closed. Continued to run and checked airflow. Found all supply and return dampers are open and all units have normal airflow. After less than an hour of runtime all 3 systems satisfied at 70 degrees. Only problem I found was economizer for front lobby unit periodically opening and bringing in fresh air. All systems are cycling thermostat normally and all units have normal operation and no faults.

Customer wasn’t home, was given door code. Upon arrival I went to first floor unit and removed all refrigerant. Replaced bad txv with new one. Pressurized unit to 350psi nitrogen and checked for leaks. Pressure held, no leaks found. Removed nitrogen and vacuumed system down to 500micron and held. Added factory charge of 11.6lbs of 410a then returned power to system and ran ac. Checked Superheat, subcool, and delta air temps. Unit is operating normal. Then I went to each thermostat and replaced the Nests with Honeywell T6 WiFi thermostats. Configured thermostats for dual fuel operation where Gas Furnaces are enabled at 40 degrees and Compressor Lockout is enabled at 35 degrees. Set all schedule periods for 78 cool 68 heat until customer sets up their own program. Left thermostat boxes on dinner table with Nest thermostats inside each box. Also included in the box is the WiFi setup booklet. WiFi needs to be setup by homeowner, I cannot set this because customer needs to use their own e

Upon arrival both systems operating. Downstairs system has very dirty filter restricting air flow, no replacements of a proper size, advised customer need replacement ASAP. Outdoor operating but coil is very dirty on 2 of 4 sides, recommend getting cleaned. Upstairs unit under high load, space kept at 80 degrees. Otherwise operation acceptable. Recommend ez trap for condensate line to protect. System’s condensate line drains to gutters. Outdoor operation normal.

I arrived at 11:00 - 11:15 and went into the studio. Olivia informed me that the call was scheduled for between 1-4 because classes are in session until 1. I called the office to let them know. I went back in and let Olivia know that a technician will return during those times. I was advised to type up my notes and close out the dispatch.

Upon my arrival I connected to the air handler board via the Cool Cloud app. I found the outdoor unit was not set up correctly. I went through and set system to matched airflow for a 2 ton system and added 12oz refrigerant to obtain 6-8 degrees superheat and 20+ degree delta temperatures across the evaporator coil. I did increase the airflow by 300 cfm to help distribute the air to the upstairs as much as possible without diminishing the capacity of the system. I called installation manager to discuss my findings. Unit operating normal.
