Great Ideas

I met Mike at the house to talk about some changes to our ductwork in the attic and he was great talking it through with me as we tried to figure out a better way. After some exchange of ideas we finally figured out a nice solution to get the proper airflow we need through the system but also position the ductwork in the attic so it rests as high as we could get it in the enclosure room up there and looks neat and professional. Overall it was a great brainstorming session and I also appreciated Mike’s patience with me as I asked different questions to try and figure it out. Which we did. It’s nice when two minds come together to solve a unique challenge which is what we did! Thanks Mike!

Replacement of indoor txv, removed refrigerant, change txv, pressure test unit, triple evacuation, and re charge unit. After new txv started unit and ran for 45 mins check performance and found an issue with evaporator coil, it’s an N coil bottom portion of coil is not getting any airflow, system was installed last summer, looking at the installation manual some brackets needed to be added for proper coil location, as right now unit unit is cooling with 15 degrees delta, I will talk to manager to see what we can do for customer. Pan needs to be placed in the right position.

Outdoor temp was reading 59F at ComfortNet thermostat. Searched for linked wireless outdoor sensor in installer options. No wireless outdoor sensor. Found outdoor sensor is hard wired (k-type) at outdoor equipment. Checked connections. OK Sensor itself may have had dirt in between metal and jacket causing inaccurate measurement. Outdoor sensor is reading accurately now. 74F
