for Groveport, OH
Christa - Groveport, OH
They arrived on a Sunday and fixed the issue in 20 minutes!
I replaced the OEM TXV and added 4 pounds of Refrigerant R-410A Puron to a 2010 Trane.
Upon arrival turned the 2010 Trane AC on. Checked pressures, pressures are 120/456 with a 25 SH and 32 SC. Checked sensing bulb on txv, secured good. Changed heat pump into heating mode on condenser, 15-20 psi drop on lineset in heating mode. Switched back to cooling and mounted sensing bulb to liquid line to get txv to react. Pressures now at 140/325 with a 4 SH and 3 SC. thermostatic expansion valve is bad inside evap coil.
