I installed a new DAT sensor for the Honeywell zoning. I tested the system to ensure proper operation with the new sensor. The system is heating to manufacture specifications. The discharge air temp sensor in need of replacement. Sensor is used to regulate supply air temperature to the home. This device prevents the supply air temperature from exceeding maximum and minimum temperature.

I arrived at our clients home for a single system with 2 zones. I first began in the attic and ensure both zone damper motors were working properly. I also tested the electric strip heat and ensured nothing was short to ground. The blower motor and indoor coil are dirty and there is early signs of some bacteria growth on the indoor coil. I brought this up to our clients daughter Brittany. And she was unsure if we had mentioned this before. I will create and send an estimate for air purification to help keep the indoor system clean and combat some of the existing growth. Outside I tested the electrical components of the unit and ensured the heat pump was running correctly. Everything passed inspection today.

I arrived at our clients home for a tune up service. After speaking with the client they informed me of high electric bills and concerns that the unit was struggling to maintain the temperature in the home. I began outside and inspected all the electrical components. I found a damaged contactor and standing Freon pressure. Inside I found the coils to be rusted and the blower to be extremely dirty. I had all my meters in place and turned the unit on to heat the home. The indoor motor is over manufacture limit and outside the compressor was actively short cycling. I took a video and showed our client. He confirmed that he has not heard the outside unit in defrost cycle like in previous years. We did briefly discuss options for repairs but our client would like to hear estimates for a full system replacement. I did switch off power to the outdoor unit and turned the thermostat to emergency heat for our clients.

Found the filter 100% clogged. The system could not move the air effectively and this caused the high limit cut out to trip. I reset the system and removed the filter. I ran the unit for a prolonged amount of time and it is working inside of manufacture specifications. Scheduled to come do duct cleaning and install a Aprilaire filter cabinet on Thursday 1/30/2025.

Performed single system heating maintenance. The system was installed in 2024 and has a 10 year parts warranty. The system is natural gas and has 2 zones. I checked amps, filter, electrical, flame sensor, gas valve, duct work, drains, cleanliness, and safeties. The system is heating in manufacturer specification. I observed some things that could be better and I have other tiny recommendations. Recommendations 1. The supply plenum is made of insulation board. When only one zone is active, there is a possibility that the seals on the supply plenum will begin to open up. This is due to the additional air pressure because of the system feeding only half of the ductwork. 2. The system has an emergency pan float switch but the drain is set up to bypass the pan. I recommend we add a in-line float switch to detect clogging before it progresses to the point of it reaching the pan. 3. Recommend performing a primary drain chemical flush to prepare it for cooling season. 4. With the sys

I arrived to the son’s concern the unit was not heating properly. He said he has been using space heaters for about a month. I proceeded to the thermostat and immediately saw it short cycle before putting it into test mode or any command. I then proceeded outside to diagnose and locate the short in the wiring. I inspected the wiring of the unit and could visibly see signs of rodents inside the outdoor equipment. I looked further and found compromised wires directly connected to the low pressure switch. This compromised wire is what is causing the thermostat to short cycle and not allowing the outdoor equipment to turn on. If left untreated or in current state it could also damage the thermostat. I presented 2 options, the first was to do a temporary fix and repair existing wires. The second a more permanent fix and replace the pressure switch. This type of damage is not covered under warranty due to it not being a mechanical issue. The client elected not to repair the unit today.

I arrived at our client home for concerns of his electric bill in the month of December. He showed me his electric bill and monthly usage for 5 days. I also went into the Trane app and looked at the usage for the past and current month. On the app it showed that only in December the auxiliary heat came on and ran. This does not line up with the outdoor Temperature which has been colder in January and in January the unit has had little to no run time I’m auxiliary heat. I began by visually inspecting the conditions of the wires, specifically the outdoor temp sensor. I found no error codes or alerts on either the indoor thermostat or outdoor CDA. I did find debris and ants at some of connection points of the wires. Which I cleaned today. I explained to our client that a problem like this is intermittent. The colder temperatures in January should have also demanded for high energy usage which it has not. Our client will continue to monitor the usage of his equipment and the sensor is st

I arrived at our clients home for a 2 system heat maintenance inspection. Our client had replaced both filters recently and did not need them replaced today. I began upstairs but tested and cleaned both sets of flame sensors and pressure switch ports for both units. I also tested and ensured the fire shutoff safeties worked. Everything passed inspection today. Our client did have a question regarding his home insulation. He has 11/12inches of insulation throughout the home which is rated at R-38. I created and sent estimates to increase it to R-49 and R-60 respectively. We also did discuss the dust in the home. I created and sent over for a full home duct cleaning which also includes two full home air purification units. This will help with allergens and dust experienced in the home. Both units are running properly on departure

I arrived for our clients concern that his heat pump unit was tripping the main breaker of his electrical panel. We discussed what was happening and how often and I began to diagnose the system. I began in the attic and tested the electrical heat kit. I then proceeded to the outdoor unit and tested the compressor, and electrical components for the outdoor unit. Everything tested in range today. I proceeded to run the unit in heat mode with 5° demand of heat. The unit was heating properly with the heat kit on and running and outdoor heat pump also. I ran the unit for more than 45 mins. I also attempted to restrict the return air to attempt to cause the unit to stress and trip the breaker. Also ran hot water to engage the water heater. Nothing happened. Our client was with me and we discussed my findings of some dirty and concerning components but nothing was causing the main breaker to trip. Our client elected to join maintenance today and clean the blower wheel to help the motor prefo

We made some adjustments on the thermostats and tested the system multiple times. The heat pump is working as intended. We will monitor the progress from the office.
