Cool the rooms your AC can’t reach: mini split installation in DeSoto County, MS
By the RW Heating, Air, Plumbing & Electrical Team · Reviewed by our NATE-certified technicians · Serving DeSoto County since 1999
Every house has that one room that never gets cool. The bonus room over the garage, a converted sunroom, or an addition that was never properly tied into the original HVAC system. In a Mississippi summer, those spaces become unusable. A ductless mini split is often the most efficient solution.
Where mini splits shine
A ductless mini split puts cooling directly into the space without relying on ductwork.
- Additions and bonus rooms that the main system cannot handle.
- Garages, workshops, and sunrooms.
- Older homes without ductwork or with uneven temperatures.
- Rooms you want to condition independently without cooling the entire house.
A properly sized ductless mini split solves hot and cold spots without extending your central system beyond its limits.
Why is ductless so efficient
Traditional ducted systems lose energy through duct leakage and heat gain in attics or crawl spaces. A mini split avoids ducts entirely and uses inverter-driven compressors that adjust output based on demand instead of cycling on and off.
The DOE Energy Saver, Ductless Mini-Split Heat Pumps notes that ductless systems are among the most efficient ways to condition individual spaces because they eliminate duct losses and allow zoning control.
Like all modern HVAC systems, mini splits also use newer low-emission refrigerants required under current federal standards.
What does an installation look like
A mini split system consists of an indoor air handler mounted on a wall and a compact outdoor condenser connected by a small refrigerant line set through a single wall penetration.
Installation is fast, minimally invasive, and often completed in a single day. Multi-zone systems can connect several indoor heads to one outdoor unit for whole-room control.
Common questions
Can one outdoor unit cool several rooms?
Yes. Multi-zone systems connect multiple indoor units to one outdoor condenser, each with independent temperature control.
Do mini splits heat and cool?
Yes. Mini splits function as heat pumps, providing efficient heating in winter and cooling in summer.
How efficient are they?
They are highly efficient because there are no duct losses and inverter technology matches output to demand. Zoning also reduces wasted energy.
The bottom line
If part of your home is uncomfortable every summer, a mini split is often the most practical and efficient solution.
