Reasonable extended warranty (oceanfront)?
I have a new construction house with 2 new Trane XR15 heatpumps in coastal NC. They have 10 year part warranty and dealer wants $1000 for each unit to have a labor warranty that also covers freon recharges. They tell me that it costs about $800 to swap out the external unit. So you have to burn through 2 external units or have an internal problem also in 10 years to make the warranty pay for itself.
Normally, I would think that is highly unlikely but this is oceanfront and most people quote a 5 year life on the external units. They are installed on the other side of the house from the ocean and are pretty well blocked from salt spray. They have the add-on needed for protection from rust required by Trane for their warranty.
This is a weekly rental and I expect some abuse from renters.
