Advice/question on mini split installation
Hello, could use some input. We had a four head mini split system installed in August of 2022. Two were installed on a flat wall on the first floor and two on a slanted mansard wall on the upstairs. Within a year one of the upstairs units failed. It developed a leak but we had to go thru an expensive process to figure exactly which one failed. The whole unit was replaced. Then earlier this year the same unit started leaking water. The company came back in said because of the angle it was not draining properly so the shimmed it out. Last week the other upstairs started leaking and when they came in they said the condenser was shot.
Could the fact that they were both installed at an angle and had drainage issues lead to the two failures?
Thanks!!
