I performed a single heating check on a 2022 gas system. I checked amps, capacitors, cleanliness, electrical connections, and safeties. The system is heating inside of manufacture specifications. I proposed installing a surge protector and chemically washing the outdoor unit it. This is to serve as an added protection and to remove oxidation on the outdoor coil. Customer stated he would be interested in the chemical cleaning on his next cooling visit.
Upon arrival we spoke to the homeowner about her concerns with the air having to be turn down more than her old thermostat. We began by place three temperature probes in the home. One at the thermostat, one in the living area and one in the clients bedroom. While we allowed those thermostats to settle and read the room temperatures, we proceeded outside to insure there wasn’t anything going on with the refrigerant levels of the system. After placing our gauges on the outside unit we found that the pressures of the system were dialed in perfectly for the conditions outside the home. After returning inside we checked all thermostats we had placed around the home and there were all reading within a degrees of the systems thermostat. We explained to the client that the system thermostat was the same brand but different model, also explained that our findings were within the ranges of the thermostat set point. Client was satisfied after seeing the results. We also discussed getting her a br
AprilAire 210/1410/910 Replacement Filter for AprilAire Whole House Air Purifiers - MERV 11, Clean Air & Dust, 20x25x4 Air Filter (each) Preformed heating maintenance. We tested all electrical components on the inside unit. All tested within manufacturer specifications. Changed the filter. Checked all electrical components on the outside unit all tested within manufacturer specifications. We found that the unit is a heat pump but set up for straight electric heat. We left estimates to covert the unit to a heat pump. Also provided estimates for a IAQ bundle and surge protection. Unit was cooling upon departure.
Upon arrival, I found that the system was fully operational and cooling with a 23 degree temperature drop. Customer mentioned her room is not comfortable. I went over options for addressing it. We spoke about mini splits, zoning, and adding a return to her room. While in the attic, I can hear the TXV opening and closing causing the refrigerant flow to change constantly.
The following estimate is to repair and connect existing gas lines to existing RTU’s. The gas nice have been disconnected or broken and been to be repaired. We are proposing to eliminate the hard pipe into the units and replace them with gas flex lines. We are also proposing to replace the existing gas shut-offs and relocate/ rebuild the needed gas sediment traps to each individual unit. After making all necessary connections we will also preform a gas line leak test to each individual RTU on site to ensure all connections are still secure. If we find any connection that is compromised we will create another estimate and scope of work needed to repair any issues found. 1- Disconnect gas and electrical connections to the last remaining RTU to allow for roof to work to be completed. - Replace existing gas lines with flex gas line - Leak tests to ensure connections are tight and secure - Splice and connect electrical connections to unit to allow for work to be preformed 2- Remove and re
Arrived to job site to evaluate the necessary scope of work needed to repair gas lines to RTU’s
I arrived and replaced the thermostat. Once I replaced it, I powered the unit back on and the fuse popped again. I began evaluating the wiring and isolated it to the outdoor unit. I checked the contactor, pressure switch, and defrost board. At first, I thought the defrost board was bad. I began tracing every wire and isolating the low pressure switch and contactor. I determined that the pressure switch was the issue. I opened the top of the unit and found that the wire was burning. The wire was not exposed, but it was still causing a short. I adjusted the wire and wrapped it with electrical tape. I ohmed it and verified that it was still good. Customer still would like the thermostat and the system is cooling.
Arrived on site found thermostat powered down. Removed thermostat and found slightly loose common wire and tightened it up. Proceeding to the attic unit I found a blown fuse. All the symptoms of a short are present so I extensively searched for low voltage short and could not find one. Replaced fuse and unit powered on without issue and continued to run for 20 minutes. Discussed with homeowner that this is an intermittent issue which tells me the issue has to be with a circuit board having ruled out a short. The thermostat or the outdoor control board could be causing this issue, but the outdoor control board appears to be in good condition and working properly at this time. This leads me to believe that the thermostat is causing this issue.
I arrived at our clients home to a blank unresponsive thermostat. Our client had no power for about 2 hours due to last nights storm. I first proceeded to the electrical panel and ensured all the breakers were turned on. I then went into the attic and found a blown fuse. I replaced the fuse but proceeded to test the outdoor heat pumps equipment. I tested the contactor and answered all of the wiring was secure. The unit turned on and began cooling. I discussed with our client how the outdoor contactor and thermostat are directly connected to the failed fuse. We discussed how adding a surge protector could help protect her equipment and she elected to I install one today. I did not charge her for the replaced fuse. After replacing the fuse I tested the system to ensure it was cooling and set the thermostat to 72º.

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.
