Zoned Comfort Without Ductwork

Mini-split and ductless HVAC installation for homes and businesses in Houma and surrounding areas.

Room additions, converted garages, and older homes in Houma often lack ductwork, making traditional central air conditioning impractical or expensive to install. Ductless mini-split systems solve this problem by delivering heating and cooling directly to individual spaces without requiring ducts, plenum boxes, or extensive wall modifications.

Coastal Mechanical Contractors, Inc installs ductless and mini-split systems for residential and light commercial applications throughout Houma. These systems provide zoned comfort control for individual rooms or spaces, energy-efficient heating and cooling options with variable-speed compressors, and quiet operation with indoor units mounted high on walls or recessed into ceilings. Installations include refrigerant line routing, electrical connections, condensate drainage, and system testing to confirm proper airflow and temperature control.

If you need climate control for a sunroom, home office, or detached workshop in Houma without installing ductwork, contact us to discuss mini-split options.

How ductless systems work in real installations

Technicians install a compact outdoor condenser unit and connect it to one or more indoor air handlers using refrigerant lines that run through a small hole in the wall. You receive independent temperature control for each indoor unit, allowing you to cool a bedroom without affecting the living room or heat a detached garage without running a full HVAC system. Installation in Houma typically takes one day for single-zone systems and two days for multi-zone setups.

After installation, you notice immediate cooling or heating in spaces that previously relied on portable units or space heaters. Indoor air handlers operate quietly, often below forty decibels, and wall-mounted remotes let you adjust temperature, fan speed, and operating mode without touching the unit. Energy costs drop compared to window units because variable-speed compressors adjust output based on demand.

Ductless systems require filter cleaning every few weeks and annual maintenance that includes coil cleaning, refrigerant checks, and condensate line flushing. Because there are no ducts to leak conditioned air, these systems deliver nearly all their output directly into the space, reducing waste and improving efficiency in retrofits and additions.

What homeowners want to know before installation

Homeowners in Houma often ask about installation time, system capacity, and how many indoor units they need for their space before scheduling a ductless HVAC installation.

How many indoor units do I need for my home?
The number of units depends on how many zones you want to control independently, room size, and insulation quality. A single outdoor condenser can power multiple indoor units, each serving a separate room or area.
What does installation involve?
Technicians mount the indoor unit on the wall, install the outdoor condenser on a pad or bracket, and run refrigerant lines through a three-inch hole drilled through the exterior wall. Electrical connections and condensate drainage are completed before startup testing.
When should I consider a ductless system instead of central air?
Ductless systems work well for homes without existing ductwork, room additions, garages, and spaces where running ducts would be difficult or expensive. They also suit homes where only a few rooms need cooling or heating.
How much energy do mini-split systems use compared to window units?
Mini-splits use less energy because variable-speed compressors adjust output instead of cycling on and off constantly. Most systems carry high SEER ratings and qualify for energy efficiency rebates in Houma.
What maintenance do ductless systems require?
You need to clean or replace filters monthly and schedule annual service for coil cleaning, refrigerant checks, and condensate line flushing. Indoor units should be kept free of dust and obstructions to maintain airflow.

Whether you need to cool a converted attic in Houma or add heating to a detached workshop, Coastal Mechanical Contractors, Inc provides ductless and mini-split installations with zoned control and energy-efficient operation. Get in touch to schedule an assessment and discuss system options.
