I just replaced my old 3 ton 10 seer with a new Trane 3.5 ton 15 seer variable speed air handler. This is a A/C heat pump unit. My electric bill is exactly the same, the cold blasts and
then the house is so stagnant that we have to run a fan to move air in the house. They told me that the unit would be so efficient that I could set my thermostat higher but that isn't so. This doesn't seem right?
I have two separate units installed on their side in my attic (2 blowers/evaporator coils with the condensors outside). One has no problems, the other does. I have had "mildew"
accumulating in the coil that no one has been able to resolve. I now have coolant leaks. The resolution offered was to replace the unit or try stop leak for $200 w/ no guarantee. The tech tells me units on their side have more issues but the other unit is not problematic. Further, if I elect to replace, access is currently limited to 20" square. The current unit was two pieces & fit through the access but I'm not aware of a replacement unit that will work. Thoughts? Solutions?
They have found some evidence of mold in her air handler of her a/c which is in her attic. She has yet to find someone who can provide a resolution after trying several a/c people who all
say that a little mold is normal. I think not! And what is the true source of the smell?

The home has two air handlers and the one that supplies the air to the upstairs did have mold
in it when it was cleaned. If there is mold in the runs she would rather have them replaced but then there's the question of how to stop future mold from getting in to the new runs? There was some mold on the insulation behind the coil that one service person said he just couldn't get to. The coil has never been removed when it was cleaned which seems weird as my service people always remove my coil when they clean it. Do you know if the light available for stopping mold only works on the coil area?
