Mini-Splits in Residential
I don't see many posts discussing mini-splits for whole home heating and cooling, and I was wondering the feasibility of using a mini-split system in a ranch style home of about 1000 square feet with three bedrooms and one bath. The home currently has an older oil furnace and to convert to a split system heat pump would require a major electrical upgrade to handle the additional amperage required to run the heat pump, as well as the costs of the heat pump and modification of existing duct work. With a mini-split system, no electrical upgrade would be needed and the oil furnace could be retained for auxiliary heat when needed.
Does anyone on this forum have an opinion and/or recommendation? Specifically, I would like feedback as to the advantages/disadvantages of using the mini-split.
Electrical upgrade might still be needed
If the house needs 3 tons of cooling, a 2 ton mini-split still needs 20-30 amps of 208V power. You might find 1 ton 120v units, but then you 'll need several for the home. 3 or
4 mini-splits installed will probably cost more then a single conventional split system
