Zone Control Without Running New Ductwork

Campbell Air Conditioning installs ductless mini-split systems in Trussville and surrounding areas for room additions, garages, and spaces where ductwork is not practical.

Ductless mini-splits cool and heat individual rooms using wall-mounted air handlers connected to an outdoor compressor. If you added a room to your Trussville home, converted a garage, or have a space that stays too hot or too cold, a mini-split provides climate control without tearing into walls to install ducts. Each indoor unit operates independently, which lets you set different temperatures in different zones.

Campbell Air Conditioning installs single-zone systems with one indoor unit or multi-zone systems that connect up to four indoor units to a single outdoor compressor. Installation involves mounting the indoor unit on an interior wall, drilling a small hole through the exterior wall for refrigerant lines and drainage, and placing the outdoor unit on a ground pad or wall bracket. The system runs quietly and uses less energy than window units or space heaters.

If you need climate control in a space without ductwork in Trussville, contact Campbell Air Conditioning to discuss mini-split installation options.

How Mini-Splits Provide Custom Zoning and Quiet Operation

The indoor air handler mounts high on the wall and blows conditioned air into the room, while the outdoor compressor sits outside and connects through a small conduit that holds refrigerant lines, electrical wiring, and a condensate drain. Campbell Air Conditioning routes the conduit through the exterior wall, secures it along the outside of your Trussville home, and connects it to the outdoor unit. Each indoor unit has its own remote control, so you can adjust temperature and fan speed independently.

After installation, you will notice that the room reaches your set temperature quickly and stays there without the noise of a window unit or the uneven airflow of a portable fan. The indoor unit runs almost silently, and you will see lower energy costs compared to electric baseboard heat or resistance heaters.

Mini-splits work best in rooms with adequate insulation and minimal air leakage. If the space has poor weatherstripping or gaps around windows, the system will run longer to maintain temperature. Multi-zone systems allow you to condition multiple rooms from a single outdoor unit, which is useful for additions, bonus rooms, or detached garages.

What Homeowners Want to Know Before Installing Mini-Splits

Most questions focus on where the indoor unit should be placed, how many zones a single outdoor unit can handle, and whether mini-splits work for both heating and cooling.

How many rooms can one outdoor unit handle?
A single outdoor compressor can connect to up to four indoor air handlers in a multi-zone system. Each indoor unit operates independently, so you can set different temperatures in each room.
Where should the indoor unit be mounted?
The indoor unit is mounted high on an interior wall, usually near the ceiling, to allow for even airflow across the room. Campbell Air Conditioning places the unit away from direct sunlight and furniture to avoid obstructed airflow in your Trussville home.
Do mini-splits provide both heating and cooling?
Yes, mini-splits function as heat pumps and provide both heating and cooling. They are effective in moderate climates and can replace window units, space heaters, or baseboard heat in hard-to-condition spaces.
How long does installation take?
Single-zone installations typically take a few hours, while multi-zone systems require more time to mount additional indoor units and route refrigerant lines. You will have climate control in the room as soon as the system is tested and operational.
Can a mini-split replace central HVAC in part of my home?
Mini-splits work well for supplemental cooling and heating in spaces not served by existing ductwork, but they are not typically used as a whole-home replacement for central HVAC unless the home is small or well-zoned.
