Estimate Summary: Warranty Condenser Coil Change-Out (Mitsubishi) Scope of Work: -Replace condenser coil under Mitsubishi parts warranty. -Includes removal of existing coil, installation of new coil, system evacuation, and recharge. Parts Availability: -Replacement coil is covered under warranty. -Estimated time of arrival from Mitsubishi: 1–3 weeks. Customer Responsibility: -Labor and refrigerant are not covered under warranty and will be billed accordingly. -A $500 deposit is required to initiate the order and secure the part. Final refrigerant charge will be determined during recharge based on system specifications.
I arrived to our client home due to the unit not cooling properly. The unit was off but had a standing pressure of 153psi. I used nitrogen to add additional pressure to the existing refrigerant in the lines. I got the pressure up to 370psi. And I began to hear an audible hissing sound coming from the base of the outdoor condenser coil. I saw a visible oil spot where the hissing was coming from also. This spot was not present on the previous visits. I used soap bubbles and partially disassembled the unit to get access to the coil and accurately pin point the leak. I took pictures and videos of the leak and called Trane tech support. They had me send them pictures to start the warranty process for the mini split. I Spoke with Mrs Johnson regarding the situation and let her know that the unit is only under parts warranty and not labor warranty. We will communicate with her updates regarding the warranty equipment and status.
I arrived at our clients home for the unit not cooling properly. Mrs Johnson explained that the unit stopped cooling Saturday and Sunday she felt like it was not cooling at all. I proceeded outside and began to search for any signs of a refrigerant leaks. I did find a small bubble present at the connection of one of the flare fittings. It was an intermittent bubble that was not consistent or very strong. I shared this with Mrs Johnson and let her know I would do my best to tighten the fitting. I also shared that if I was unable to correct the issue today we would call the install team to cut and create a new flare to be connected. I tightened the flare connection and pulled a vacuum down to 324 microns. I let it sit for 20 mins before weighing in the manufacture charge of 3lbs 9oz. I also changed the valve core as a proactive measure to ensure everything was tight and sealed. I let the run for more than 30 mins and bubble tested the fittings and used my leak detector and found no le
Returned to home to correctly charge mini split with refrigerant. We removed the existing refrigerant and then proceeded to pull a vacuum on the entire system. We pulled the vacuum down below the standard 500 microns to ensure no leaks were present in the system. We reached 330 microns before we weighed in the exact refrigerant charge of 3lbs 9oz. Once the unit had refrigerant we proceeded to run the system in cooling. I measured 41° air directly at the blower wheel. Our client is aware it may take a good amount of time to reach the desired set point. The 7nit is cooling properly on departure.
System was off upon arrival . Made a call for cooling on remote. Refrigerant pressures were good at first cooling start up around 121psig but only receiving a 10 degrees temperature drop across evaporator. Turned on econo cool mode and didn’t function any better. Turned system off then into heating and got a 17 degrees temperature rise. Turned system off then turned cooling back on and refrigerant pressure reading dropped drastically to 30psig. Tech support not available during after 5pm. Possibly control board communications failure to outdoor components due to the intermittent failures that randomly occur. Will contact tech support in the morning and submit diagnostics and readings to make the next step in diagnostics/repair process. Possibly need return visit pending tech support recommendations. Recommended turning off equipment and homeowner was ok with that.
Upon arrival client stated that unit was cooling at 7am at 62 degrees, client turned unit off for about 30mins and the unit was struggling to keep the area cool. We proceeded to check temps of the room and coming out of the unit. We proceeded outside to check refrigerant pressures and found that the unit was about 12oz low. We added the 12oz to the unit and unit started to stabilize. While adding refrigerant we also measures the RLA amps on the outside unit to ensure the proper amp draw and Freon pressure. Unit was cooling properly upon departure. 48 degrees was coming out of the supply head. We did also discuss option to start with a virgin charge that would involve a full system vacuum and weighing in refrigerant to manufacture specifications. Client is aware of this option and declined due to potential cost associated with it.

Upon arrival client stated that unit was cooling fine when we did the maintenance visit on June 30th. Now it’s not cooling at all. Upon inspection we did find a leak on the flare nuts outside. We tightened up the fittings and leak tested, no leak was detected durning final test. We quoted 4lbs of refrigerant. As we added refrigerant back to manufacturer we did notice it was about only 2.5lbs low. We rinsed off condenser coils to ensure cleanliness and to make sure the unit was not suffocating. Unit cooling upon departure. ADD NITROGEN PRESSURE BOOST SINGLE UNIT INDOOR OR OUTDOOR UNIT ONLY MUST BE USED WITH AN NCD LEAK SEARCH REPAIR REFRIGERANT LEAKS CAN CAUSE HIGHER ENERGY COSTS AND DAMAGE TO THE SYSTEM. WE ALWAYS RECOMMEND A LEAK SEARCH WHERE THE LEASK IS NOT VISIBLY EVIDENT.
This service call was for the Amana split system and not the mini split. I found the capacitor reading .2 on the compressor side. This resulted in it tripping at start up. I replaced it and tested the system. The system is now cooling.
I performed a 3 system cooling maintenance. The systems are 2 mini splits. One of these systems had 3 heads. The other has 1 head. 1 main unit with 3 zones. I checked amps, capacitors, filters, drains, electrical, and cleanliness. I found that everything mini split related needs to be cleaned. The normal mini split heads would be good with no rinse cleaner. The cassettes need to be pumped down and pulled be cleaned without causing damage. The outdoor units need to be chemically cleaned with the portable jetter. I request3d pricing for the cleanings and quoted the normal mini split heads.

Homeowner stated that the unit is not cooling,, that its blowing hot air,, that he set the blower on so he could have some air circulating inside the house because it’s very hot. Started diagnostic at the condenser unit after setting thermostat to cool,, notice a humming sound coming from the unit as we were getting closer,, found a bent condenser fan blade ,, seems that some limps got inside causing damage,,condenser fan motor was extremely hot,, we managed to get the unit up and running for now ( customer has special needs),, since fan motor/ blades are not balanced properly we recommended to replace both because we believe the condenser fan motor is damaged as well due to overheating.
