A mini-split is a ductless heating and cooling system made up of:
Unlike central air, a mini-split delivers conditioned air directly into individual rooms without any ductwork at all.
With Tulsa and OKC seeing both scorching summers and genuinely cold winters, a heat pump mini-split gives you year-round comfort from a single system.
Mini-splits work especially well for:
Skip the cost of extending existing ductwork into new square footage.
Keep a workshop, gym, or home office comfortable in every season.
Independent, efficient climate control without a full HVAC installation.
Add comfort without cutting into walls or ceilings.
Target the problem room directly instead of overhauling the whole system.
one indoor unit paired with one outdoor unit. Best for bedrooms, offices, garages, workshops, and sunrooms.
multiple indoor units connected to a single outdoor unit. Best for whole-home comfort, multi-story homes, ADUs, and homes with several rooms that each need different settings.
Single-zone systems generally cost less than multi-zone setups, and larger homes typically need more indoor units. For accurate pricing, we recommend an in-home evaluation — Steel Horse provides free estimates.
We assess square footage, insulation, room usage, and existing electrical capacity.
Correct sizing means better efficiency and a longer-lasting system.
We help you decide between single-zone and multi-zone, indoor unit style, and system capacity.

In many cases, yes. Without duct losses, and with independent zone control, mini-splits can meaningfully cut wasted energy.
How long do mini-split systems last?
Most professionally installed and maintained systems last 15–20 years.
Can a mini-split heat my home in winter?
Yes — modern heat pump mini-splits provide both heating and cooling, which suits Oklahoma’s swing between hot summers and cold winters.
Do mini-splits require ductwork?
No. They operate entirely without ducts.
How many rooms can one system cover?
A multi-zone system can serve several rooms, depending on the design and capacity you choose.
