Posted prices for a 150 to 300 square foot glass sunroom
A sunroom along the I-35 north corridor is a glass box that cooks by noon. Window units have nowhere honest to sit. Portable machines dump heat into the same air they claim to cool. You want the room usable in July, not a greenhouse with furniture.
Old West Minisplits posts the price before anyone sets a ladder. One zone is $2,000, two zones are $3,700, three zones are $5,400, and four or more zones are quoted individually. These figures are new installs only, never repairs or service calls. Start at /#quote when the sunroom is ready.
Glass load is not square footage
A 200 square foot bedroom is not a 200 square foot sunroom. South and west glass in Killeen, Temple, Belton, Harker Heights, Copperas Cove, Waco, Salado, and Jarrell collects sun from breakfast until late afternoon. Shade sails and blinds help. They do not replace a machine sized for solar gain.
A ductless mini split is a heat pump. It cools through brutal Central Texas summers and handles mild winters without a furnace. The indoor head mounts on a solid wall, a corner, or a post. It does not occupy the one operable window you still have.
Count zones like a calculator
Treat 150 to 300 square feet of sunroom as one zone if it is a single open glass room. That new install is $2,000. If the sunroom shares an open wall with a living room you also want cold, count two zones at $3,700. Three separate spaces are $5,400.
Glass does not add a zone by itself. It can mean a larger indoor head on the sunroom circuit. Licensed contractors set the equipment after they see mounting and the line-set path. Honest exceptions, stated up front, are a very long line set, a panel upgrade the house already needed, or unusually difficult mounting.
What the posted price actually covers
The flat price covers equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and even a Home Depot run for touch-up paint. There are no trip fees or upcharges on a standard new install. Installations are performed by licensed contractors.
Ductless installs in Central Texas commonly run $3,000 to $6,000 per zone on a custom quote from other contractors, most of whom require an in-home visit before quoting. Old West Minisplits puts the number on the page. If you need a repair or a service call, this page is not the price, because these flat prices are for new installs only.

Straight answers
Is a 150 to 300 square foot sunroom really $2,000?
If it is one open room and a standard new install, yes. One zone is $2,000. Two zones are $3,700. Three zones are $5,400. Four or more zones are quoted individually. Glass can change head capacity, not the zone count by itself. Confirm the count at /#quote.
Do I need two zones because of all the glass?
No. Glass raises the cooling load on the sunroom head. A second zone is a second indoor unit in a second space. Count rooms, not panes. An adjoining living area you also want conditioned is when the $3,700 two-zone price applies.
Can I use this price for a dead window unit or a service call?
No. These flat prices are for new installs only, never repairs or service calls. If this page could be misread as a repair rate, it is not. A new mini split in the sunroom is the job this number covers.
What sits outside the $2,000, $3,700, or $5,400 figure?
A very long line set, a panel upgrade the house already needed, or unusually difficult mounting. A panel upgrade is work a licensed electrician handles, arranged separately. Insulation, roofing, and shade structures are separate trades as well. Standard electrical for the mini split is already inside the flat price.
