Glassboro asks for eleven months of run time
Glassboro homes need heat from October through April and cooling from June through September. That is 11 months out of the year your mini-split is working, with only a short break between seasons. Winter nights average 28°F, and summer afternoons average 85°F, so the system has to hold its own at both ends.
A mini-split installed here has to meet the federal minimums for a split-system heat pump if it was built on or after January 1, 2023, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With this little downtime between seasons, sizing it right for both the summer heat and the winter cold matters.

New Jersey requires HVAC contractors to hold a state license.
New Jersey licenses HVAC contractors through the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) Contractors. The board tests and keeps a record of the contractor, not each job, so the license someone holds for this work is the same one that covers everything else they do. Gloucester County and its towns cannot add their own HVAC licensing requirement on top of that, so the state board's test and record are what stand behind whoever does the work, no matter which town in the county the house is in.
That license is what covers the mini-split installation itself. In most cities and counties, a job like this also needs a permit from the local building office, with an inspection once the work is done, and that inspection is what checks the mounting, the electrical connection and the line set, separate from the license.

- Is a mini split worth it?
- For most homes, yes, especially if you're heating or cooling a room that isn't on your main ductwork, or you don't have ducts at all. A mini split handles both heating and cooling from one outdoor unit, and it runs efficiently down into cold weather far better than older electric resistance heat. With winter lows here averaging 28°F, look for a cold-climate rated unit if it's going to carry real heating load rather than just supplement a furnace.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Single-zone systems cover one room or open area. Multi-zone systems run several indoor heads off one outdoor condenser, each with its own thermostat, so you can heat or cool rooms separately. A contractor will size the outdoor unit and the number of heads to the square footage and layout of the house.
- Can a mini split heat a whole house?
- It can, if it's designed as a whole-house system with enough indoor heads to reach every room and an outdoor unit sized for the coldest days here. That's a bigger job than adding one or two zones, since every room needs its own head or a connection to existing ductwork through a ducted air handler. Most homes here heat with gas, so a mini split often gets added alongside an existing furnace, but a full system can carry the whole heating load on its own when it's sized for it.
