Targeted Comfort Without Adding Ductwork
Ductless Mini Split Systems in Orlando for conditioning spaces where duct installation is impractical or cost-prohibitive
All Week Heating & Cooling Inc. installs ductless mini split systems in Orlando for homeowners adding conditioned space to garages, converting sunrooms into home offices, or cooling guest suites above detached garages where running ductwork through finished ceilings and walls would require extensive demolition and repair. These systems mount an indoor air handler on the wall or ceiling and connect it to an outdoor compressor unit through a small conduit that carries refrigerant lines, electrical wiring, and a condensate drain, requiring only a three-inch hole through an exterior wall.
Each indoor unit operates independently with its own thermostat, allowing you to cool or heat a single room without affecting temperatures elsewhere in the home. This zoning capability reduces energy waste in spaces used occasionally, such as workshops or guest bedrooms, where running a central system to condition the entire house makes no sense. In Florida's climate, mini splits provide efficient cooling during long summers and adequate heating during brief cold snaps without the ductwork losses that reduce central system efficiency by up to thirty percent in poorly sealed duct systems.

If you need climate control in a space without existing ducts, contact All Week Heating & Cooling Inc. to review mini split options and determine the correct system size for your room dimensions and insulation levels.
Installation and Performance Details
You will see an indoor unit mounted high on the wall or recessed into the ceiling, connected to an outdoor condenser by refrigerant lines that run through a wall sleeve and along the building exterior. Installation typically completes in one day for a single-zone system, and the unit begins cooling or heating immediately after startup and refrigerant testing. Mini splits operate quietly, with indoor noise levels around thirty decibels, comparable to a whisper, making them suitable for bedrooms and offices where traditional window units would create disruptive noise.
After installation, you will control temperature using a handheld remote or wall-mounted panel, adjusting fan speed and airflow direction to suit your preferences. The room will reach the set temperature faster than with a window unit, and you will notice more even cooling without the cold drafts that occur directly below wall-mounted air handlers. All Week Heating & Cooling Inc. provides service and repair for all major mini split brands, addressing refrigerant leaks, compressor failures, and control board issues that prevent the system from responding to thermostat commands.

Multi-zone systems connect up to five indoor units to a single outdoor compressor, allowing independent temperature control in multiple rooms while requiring only one outdoor unit. This setup works well for additions with several rooms or for homes where central ductwork serves the main living area but not newer sections. Each indoor unit must be sized correctly to match room volume and heat load, as undersized units will run continuously without reaching the set temperature, while oversized units will short cycle and fail to dehumidify properly.
What to Know Before Installing a Mini Split
Homeowners in Orlando often ask about energy costs, maintenance requirements, and whether mini splits cool as effectively as central systems.
How much does it cost to run a mini split compared to central air?
Mini splits use inverter-driven compressors that adjust speed based on demand, typically using thirty to forty percent less energy than central systems when cooling a single room or small addition.
What maintenance does a ductless system require?
Indoor units have washable filters that need cleaning every month, and the outdoor coil requires annual cleaning to remove dirt and organic debris that restrict airflow.
When should I choose a mini split instead of extending existing ductwork?
If the space is more than thirty feet from the nearest duct trunk line, or if running ducts would require cutting through load-bearing walls or finished ceilings, a mini split installs faster and costs less.
Why does the indoor unit drip water during cooling?
The condensate drain line may be clogged or improperly pitched, causing water to back up and overflow from the drain pan onto the wall or floor.
How long do mini split systems last?
With annual maintenance and proper refrigerant charge, mini splits typically operate for fifteen to twenty years, similar to central systems but with fewer components that require repair.
