Mini split planning tools
Work out which mini split fits your house and what it typically costs, before we visit.
Pick the question you have
Which tool should you start with?
Start with the assessment if you aren't sure what kind of system you need. Start with the cost calculator if you know the rooms and want a planning range.
Both are free from Roomwise DC Mini Splits, and either result can go with an estimate request, so you only describe the house once.
- The assessment asks about the rooms, your heat and cooling, ducts, the type of home, historic district, outdoor space and the panel.
- The cost calculator asks about the job, the number of rooms, what complicates it and the heat it replaces.
What will the calculator show?
Our typical range for your answers, with each part as its own line. A standard one-room install runs $3,000 to $6,000; a standard two- to four-room system runs $5,000 to $14,000.
Historic review, long line runs and panel work move a job into our complex ranges. Your price is set in the written estimate after the home visit, and the DC cost guide explains each driver.

Questions about the tools
Do I need to know my panel size or line set length to use the tools?
No. The panel and line set questions each take a "Not sure" or "I don't know" answer, and nothing asks you to open a panel or measure a line. We check the panel, the line routes and the outdoor spot at the home visit.
Can I send a tool result to my partner or my condo board?
Yes. Both tools write your answers into the page address, so copying the link shares the same result. Nobody else sees it unless you send the link or include it with the form.
Which tool should I use if I already have a mini split?
The cost calculator. Choose "Replace an existing mini split" and it adds lines for each head after the first and for a new line set if the old one fails its pressure test.
Prefer to talk it through?
