He kept having problems with the air handler chilly up as ice would form on the coil & impede both air flow & natural defrosting effects.
I don’t care about the way that up-to-date houses are built in our neighborhood. The developers get the cheapest companys that they can find, often ones with reviews so terrible that members of the public will refuse paying for their service. You have so multiple things that could go wrong with the foundation alone. My friend’s up-to-date home was plagued with sewer gas problems because the pipes were laid incorrectly & the concrete foundation pushed them further out of alignment as it settled in five to six years. It got so terrible that the p-traps under the sinks would get pulled from insufficient air ventilation in the plumbing system. This lets sewer gases into the up-to-date home from the pulled p-traps. I also hated how they installed his a/c upon finishing the house. They insisted on hanging it from the ceiling in the garage, in section because it’s cheaper & easier than running refrigerant & condensate lines into the heart of the house. He kept having problems with the air handler chilly up as ice would form on the coil & impede both air flow & natural defrosting effects. This pushed him to talk to a local HVAC company about getting a up-to-date a/c & finding a better location for the air handler. After getting it put into an aged coat closet, the up-to-date a/c works much better than the aged one. They have the same air cooling capacity & the same SEER value, but the up-to-date one never freezes over. All of that sizzling garage air is no longer affecting the energy efficiency of his HVAC system.
