Eleven months of work for a system that has no season off
Yonkers homes need heat or cooling eleven months of the year. Winter nights average 24°F from December through February, and summer afternoons run around 82°F. A mini-split installed here spends most of the year holding a temperature, not resting between seasons.
Any mini-split sold new has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With eight months of heating and three of cooling to cover, sizing it right for both jobs matters as much as meeting that minimum. The area has also logged 42 winter storms and 167 damaging wind events over the past ten years, and the outdoor unit needs to be mounted and wired to hold up through that.

- Is a mini split worth it?
- For most homes, yes, especially where a room runs hot or cold and ductwork can't reach it easily. You get heat and cooling from one system, and you control each room on its own instead of pushing air through ducts that lose heat along the way. Yonkers winters get cold, down to 24°F on average overnight from December through February, and a mini split rated for cold climates will still put out heat at those temperatures. A contractor can look at your house and tell you whether it makes sense for your situation.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, up to eight on most multi-zone systems. Each indoor head handles one room or open area, and you set the temperature separately for each one. How many you need depends on the size and layout of your house, so a contractor will need to walk through it before sizing the system.
- Can a mini split heat a whole house?
- It can, if there's an indoor head in enough rooms to cover the space, but a single head in one room will only heat that room and whatever's open next to it. Homes here need heat eight months a year, October through May, with nights averaging 24°F in the coldest stretch, so the system has to be sized for that cold, not just for mild days. A contractor can tell you how many zones your house would need to heat it all.
