Help me help a buddy. My best friend is building a new home with CPMorgan (a tract home builder with a less than stellar reputation). During the construction of his home his heat pump (which has been undersized by half a ton but that's another story) was hacked to run on electric heat strips and provide heat for the workers....keeping in mind that no furnace filter was installed and that the air handler has been running nonstop during the drywall and spray painting phases of construction. I know the damaging effects this has on the coils inside the air handler but where do I point him for that information and more importantly how does he get the builder to rectify the situation (I'm assuming having the coils cleaned professionally?)? For what it's worth it a builder's grade Bryant heatpump.
Many thanks, Jonathan
