Ten months of heat, barely any cooling
Salem asks a mini-split to run most of the year, not just in a few hot weeks. Heat is needed September through June, and winter nights average 33°F through December, January and February. That means the heat pump side does the real work here, holding steady on cold nights while the compressor cycles on and off for months straight.
Summer afternoons average just 76°F, so cooling is a small part of the job by comparison. A new unit still has to meet the federal minimum either way. Any split-system heat pump built from 2023 on has to hit 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, mini-splits included. With just over half of homes here heating with electricity, and winter storms known to knock out power, it's worth asking how the system you choose handles a cold snap if the power drops.

Oregon requires HVAC contractors to hold a state license.
The license belongs to the contractor's business, not to any single job, and the Construction Contractors Board keeps that record on file. Work under $1,000 is the one job the state lets go without a licensed contractor, but a mini-split installation runs well past that, so this job needs one.
The license does not stand alone here. Replacing a heat pump like a mini-split needs a permit from the local building office in most cities and counties, along with an inspection once the work is done, and that is where someone outside the contractor looks at what got installed.

- Is a mini split worth it?
- For homes here, yes, since heat is needed from September through June and a mini split handles both heating and cooling from the same unit. It heats efficiently even on cold nights, and you get room by room control instead of heating the whole house at once. A contractor can look at your house and tell you what size and how many zones make sense.
- How many rooms can a mini split cover?
- A single outdoor unit can run several indoor units, depending on the system. Each indoor unit is sized for the room it serves, so a contractor works out how many zones your house needs based on room sizes and layout. Larger homes often use more than one outdoor unit to cover every room without overloading one system.
- Can a mini split heat a whole house?
- Yes, if it is sized and placed for that. Each room or zone needs its own indoor unit, so a whole house system means an indoor unit in every room you want heated, not just one unit trying to reach the whole place. With winter nights here averaging 33°F, a contractor will size the system so it keeps up on the coldest nights, not just the mild ones.
