Mini-splits are the most misquoted equipment in this trade. People get a $2,000 number from a YouTube video and a $15,000 number from a salesman in the same week, and both can technically be true, because “a mini-split” can mean one small wall unit or a five-zone whole-home system. Here’s how the pricing actually breaks down in DFW, so you can tell where your project lands before anyone is standing in your kitchen.
What drives the price
Four things: how many indoor units (called heads), the total tonnage, how far the refrigerant lines have to run, and whether electrical work is needed. A single head serving one room is a fundamentally different job than four heads running off one outdoor unit across a whole house.
Typical DFW ranges
Single-zone, one room. A garage gym, a home office over the garage, a sunroom that never cools. Equipment plus installation typically lands in the mid four figures. Where exactly depends on brand tier, line length, and electrical.
Two to three zones. A master suite plus a bonus room, or an addition the main system can’t reach. Low five figures is the honest range for quality equipment installed right.
Whole-home multi-zone. Common in older homes with no ductwork, and I do a lot of these in Preston Hollow and the M Streets where the house was built long before central air and the attic can’t take ducts. These run comfortably into five figures and compete directly with the cost of a ducted system plus all-new ductwork, which is exactly the comparison you should make.
Anyone who gives you one flat number for “a mini-split” without seeing the house is guessing. I quote after a load calculation, in writing, and the number doesn’t move after we start.
When a mini-split beats central air
- No existing ductwork and nowhere good to put it. Older Preston Hollow, Lakewood, and historic McKinney homes especially.
- One problem room. Putting a head in a hot bonus room costs far less than resizing the whole system.
- Garage shops, casitas, and outbuildings. This is most of my Aubrey and Celina acreage work.
- Additions, when tying into the existing system would overload it.
When it doesn’t
If you have decent ductwork and one properly sized central system can carry the house, central air usually wins on cost per ton and on looks, since some people never warm up to a unit on the wall. And an underperforming central system is often an airflow problem you can fix for far less than any new equipment. I’ll tell you which situation you’re in, because installing equipment you didn’t need is how contractors lose 22-year reputations.
The heat side is the sleeper benefit
Every mini-split we install is a heat pump, so it heats too. In a DFW winter that means efficient heat almost all season, and the one-room-office crowd stops heating the whole house to keep one room comfortable.
