Independent Climate Control for Detached Guest Houses
A detached guest house should not rely on noisy window units or an overburdened main house system. Running central ductwork out across the yard is expensive, inefficient, and impractical for a standalone building.
Old West Minisplits puts dedicated heating and cooling inside your guest quarters with zero guesswork on cost. One zone costs $2,000 flat, two zones cost $3,700, and three zones cost $5,400. Secure your installation date at /#quote.
Why Ductless Fits Standalone Backyard Quarters
Detached suites, casitas, and backyard rentals need private temperature controls that do not interfere with the main residence. Mini split heat pumps deliver powerful cooling during hot Texas afternoons and dependable heat through winter cold snaps.
The outdoor condenser sits quietly on a pad outside the guest house, connected to the indoor air handler by a compact line set. Your guests set their own thermostat without touching the main house controls.
Clear Upfront Pricing Without Contractor Games
Standard contractors often charge $3,000 to $6,000 per zone and demand an in-person sales visit before revealing a quote. Old West Minisplits posts the number openly because your time matters.
Our flat prices cover the equipment, labor, standard electrical hookup, line sets, refrigerant, full system testing, and complete cleanup. We even pick up touch-up paint from Home Depot if wall patching requires it.
Honest Installation Boundaries and Trade Scope
These flat rates apply strictly to new system installations, not diagnostic visits or repair calls on existing equipment. Every installation is completed by licensed contractors who ensure your equipment runs correctly from day one.
We state the rare exceptions directly instead of hiding them in fine print. If your guest house requires an electrical panel upgrade, an unusually long line set, or extreme mounting work, we point it out up front. Any separate trade work like heavy electrical upgrades remains something you arrange directly with a licensed electrician.

Straight answers
How much does it cost to install a mini split in a detached guest house?
A single-zone installation is $2,000 flat. Two zones cost $3,700 and three zones cost $5,400. These prices cover equipment, labor, standard electrical, line sets, refrigerant, testing, and cleanup.
Can a mini split handle both summer heat and winter cold in Texas?
Yes. Mini splits are heat pumps designed to cool through extreme Central Texas heat waves and warm the space through winter cold snaps without needing a furnace.
Does the flat price include running heavy electrical to the guest house?
Standard electrical connection from the outdoor unit to an existing, adequate guest house disconnect is included. If the building requires an electrical panel upgrade or a new subpanel from the main house, that work is arranged separately with a licensed electrician.
Are these prices valid for repairing an existing mini split in my guest house?
No. Our flat rates apply exclusively to new installations. We do not perform repair services or service calls on existing equipment.
