We had a whole house Trane ductless mini spiit system installed in our home in 2016. The AC worked great but we could not get the living room above 50 degrees in the winter! The company was nice enough to come out numerous times to check our system, they said it was checking out fine.I asked several times for an estimate to fix the problem with the heat.I asked the owner if we need an additional head for the living room or a bigger compressor for this large area . I never heard back from them and we finally gave up on it and had it removed from our home. We lost almost 10k on this system and the mini split was one of the worse purchases we ever made. We had a natural gas furnace/AC installed by a different company.and we are very happy with it.
