Carriage House Climate Control Without Ductwork or Games
Detached carriage houses, guest suites, and secondary living quarters face brutal Central Texas heat without the benefit of main-house ductwork. Trenching duct lines from a main residence is impractical, while noisy window units ruin the space and run up electric bills.
A ductless heat pump solves the problem cleanly. Old West Minisplits installs new systems at fixed prices: $2,000 for one zone, $3,700 for two zones, and $5,400 for three zones. You get cooling for hundred-degree summers and heating for winter without a sales standoff.
Dedicated Heating and Cooling for Detached Living Spaces
Carriage houses often sit above garages or stand alone as backyard casitas. These structures experience rapid heat gain through roofs and exposed walls, demanding fast and efficient cooling. Mini splits deliver targeted temperature control right where it is needed without wasting power on empty square footage.
Because each indoor unit operates independently, you only condition the carriage house when someone is using it. When guests leave or the workspace is closed for the day, you adjust the setpoint without affecting the primary home.
Clean Installation Without Destroying Finished Spaces
Traditional HVAC requires running bulky ducts through rafters or dropping ceilings, which ruins the open charm of a detached structure. A mini split requires only a three-inch hole in an exterior wall to connect the indoor head to the outdoor condenser.
Our licensed contractors handle the equipment, line set, standard electrical connections, refrigerant charging, and full system testing. We even make a Home Depot run for touch-up paint to keep the structure looking sharp.
Honest Pricing Posted Up Front
Most HVAC contractors treat carriage houses as specialty jobs, quoting $3,000 to $6,000 per zone after an in-home sales pitch. We state our numbers on the board before we ever set foot on the property. These rates apply strictly to new installations, not repairs or service calls.
If a project involves an exceptionally long line set, an existing electrical panel upgrade, or difficult mounting, we state those exceptions clearly. Standard jobs get installed at the flat rate with zero surprise upcharges or trip fees.

Straight answers
What are your flat prices for carriage house installations?
We charge $2,000 for one zone, $3,700 for two zones, and $5,400 for three zones. Larger installations with four or more zones are quoted individually. To get started, submit your project details at /#quote.
Does the flat price include electrical service to a detached building?
The flat price covers standard electrical connections from an existing, adequate subpanel or service disconnect. If your carriage house needs a main panel upgrade or a new subpanel run from the house, that work must be arranged separately with a licensed electrician.
Can I use these flat prices to fix an existing mini split in my carriage house?
No. Our published rates apply strictly to brand-new mini split installations. We do not provide repair work, maintenance, or service calls for existing equipment.
How do mini splits handle winter in Central Texas carriage houses?
Mini splits are high-efficiency heat pumps. They pull heat from outside air to warm the space quietly through mild Central Texas winters, eliminating the need for baseboard heaters, space heaters, or a gas furnace.
