Takes about a minute. No obligation.
Sizing a mini-split in Fulton County starts from the heating load, because there is no meaningful cooling load to anchor the calculation. Homes in Fulton County, NY have essentially no cooling season — no month of the year is warm enough to call for it. A contractor quoting a system here cannot use summer demand as a cross-check on their math. The heat exchanger and the compressor will run through a long heating season, and a unit that is undersized on the heating side will show that failure under the worst outdoor temperatures, not during a mild stretch when the gap is easy to miss.
Electrical service in a house this old was sized for something different from what runs in it today. Half the homes in Fulton County, New York were built in 1954 or earlier (2020-2024 ACS 5-year). That gap between original wiring and a new mini-split's draw is where the real installation question sits. A contractor here checks the panel before anything else, because what it can carry determines whether the job is straightforward or whether an electrician comes first.
What a Mini-split Installation Puts in Your Home
The indoor air handler mounts high on an interior wall in the room being conditioned, and it is the piece a homeowner sees every day. The outdoor unit sits on the ground or on a bracket outside the home and houses the compressor and the rest of the mechanical core.
A refrigerant line set runs through a small opening in the wall to connect the two units, and a condensate drain line carries moisture out of the indoor unit. A dedicated disconnect or control wiring also runs alongside those lines to tie the system together.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your home.
