I'm having a 15 year old, 2 ton Goodman coil replaced with the same coil (no duct work needed). The condenser is also 2 tons. I asked the HVAC installer if he could use a TXV. He said Goodman has a TXV kit, XV24-60, that would work. It's for any Goodman coil from 2 to 5 tons. I thought a TXV should be sized closer to the condenser size. Is a TXV that will work from 2 to 5 tons okay or should he use a TXV closer to 2 tons?
