Ductless Mini-Split Decision
Hi, a friend of mine is an HVAC contractor and he’s suggested a 19k BTU ductless mini-split system to replace the gas furnace that currently heats my 1000 sq foot home. I live in California Climate Zone 5. The house has just 2 beds and 1 bath. While it has no insulation now, I’m going to blow cellulose into the attic and condition the crawlspace with closed-cell foam.
Will a 19k BTU Fujitsu outside along with a 15k unit in my living room (316 sq ft) and 9k unit in one bedroom (162 sq ft.) make the house comfortable? It never gets below 40F here and rarely above 90F.
I had a load calculation done before embarking on the insulation job, and that number came out to 34k. There are single pane windows that I don’t have immediate plans of replacing.
