My Grandfatherrents’ apartment was built in the 1930s, and its original furnace consists of a boiler and radiators; The extended family has been discussing having central a/c installed for them because on humid afternoons, both my Grandmother and Grandfather have difficulty breathing! We’ve had more than 2 Heating & A/C dealers supply us quotes and occasions for the installation of central a/c.
Naturally, my buddy and I could install window units ourselves, but my buddy and I would rather have the entire apartment cooled evenly, also, because window units are so noisy, my Grandfatherrents would sacrifice what they are able to hear.
They both have hearing aids and struggle with deciphering each other’s conversations, however one cooling specialist told us that my buddy and I could install HVAC duct in the house, but it would require tearing holes in the walls and ceilings in order to do so. And if the installer made any errors, the original plaster and woodwork could be disfigurementd. And sacrificing space for the HVAC duct means losing closet space or lowering ceilings. One Heating & A/C business told us about VRF, or variant refrigerant flow, systems. This is a ductless system that uses one outdoor condensing component that connects to more than 2 indoor units, and vRFs supply each zone the power to control its own temperature. The ninth business encouraged us to go with ductless mini split systems, in which outdoor and indoor units are connected with a small conduit with refrigerant and electrical lines, but mini splits are small systems which are most often used to cool one or two rooms. After quite a bit of discussion among the extended family, my buddy and I decided to use the variant refrigerant flow system.
