Eleven months of work, out of one unit
In Vinton, a mini-split runs from October through April to keep the house warm, then June through September to keep it cool. That is eleven months a year the system is doing something, with barely a break in between. Winter nights average 28°F, cold enough that a heat pump has to work for its heat rather than just moving warm air around. Summer afternoons average 84°F on the other side of the year.
Any mini-split installed new has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That is the floor, not a feature, so it is worth asking what a contractor is installing above it given how many months this one will run.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors tests and records the contractor, not the job in your home. That license stays with the business across every installation it does. Virginia sets one exception. Work under $1,000 does not need a licensed contractor. A mini-split installation runs well past that, so this job falls under the license.
Most cities and counties also require a permit from the local building office before work like this starts, with an inspection once it is done. That inspection covers the installation itself, separate from whatever the license already covers on the contractor.

- Is a mini split worth it?
- For most homes it is, especially where a room or addition has no ductwork to extend. A mini split heats and cools that space directly, and it runs on electricity, so it works anywhere you have a power line reaching it. Homes here need heat from October through April and cooling from June through September, so the same unit earns its place in the wall most of the year. A contractor can tell you whether it fits your house better than extending existing ductwork.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Each indoor head is sized for the room it hangs in, so a one-room installation covers just that room, while a multi-zone setup can cover several rooms off the same outdoor unit. The right number depends on the size and layout of the rooms involved. A contractor sizing the job will walk the house and tell you how many zones it needs.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to reach every room, but a single head only heats the room it is mounted in. Winter nights here average 28°F from December through February, so whatever system goes in has to be sized to keep up on the coldest nights, not just the mild ones. A contractor can calculate the heat loss for your house and tell you how many zones a whole-house setup would need.
