Ductless mini-split installation in Birmingham, AL
Some rooms were never on the central system, and some houses never had ducts at all. A ductless mini-split heats and cools those spaces through a small line set, with no new ductwork.
Ductless systems pair one outdoor unit with one or more indoor heads, joined by a copper line set through a hole about three inches wide. Each head has its own temperature setting. Zeltman Heating & Air sizes each zone, plans the head and line set placement around your walls and gives you the installed price before scheduling.
Where ductless makes more sense than extending ducts
Extending central ductwork to a new space sounds simple until you look at the airflow. The existing system was sized for the original house, and a long new run to a bonus room over the garage often delivers weak, warm air in July. A mini-split adds its own capacity for that space instead of borrowing from the rest of the house.
Older Birmingham homes are the other big group. Avondale and Forest Park have plenty of 1900s to 1920s bungalows with plaster walls, tall ceilings and no attic or crawlspace room for ducts. Window units have filled that gap for decades. A multi-zone system with a head in each main room replaces them with quiet, efficient heating and cooling.
Sunrooms, converted garages, workshops and finished basements round out the list. These spaces tend to have more glass, less insulation or different hours of use than the rest of the house. Giving them a separate zone keeps them comfortable without overcooling everything else, much like HVAC zoning does for ducted homes.
Mini-splits are heat pumps, so they heat as well as cool. Inverter compressors ramp up and down instead of cycling on and off, which keeps humidity down in summer. Mitsubishi Electric, Daikin and Fujitsu are the names we install most, and we help you choose based on the room rather than the badge.
What we plan before a mini-split goes in
- Heat load of each room or zone, not the whole house
- Head location for airflow, furniture and wall framing
- Line set route, length and the cleanest exterior path
- Condensate drain route by gravity or a small pump
- Outdoor unit spot on a pad or wall bracket
- Dedicated circuit and disconnect at the outdoor unit
- Single-zone versus multi-zone equipment for your layout
- Plaster, brick or siding details where the line set exits
What ductless mini-split installation costs in Birmingham
$3,780 to $6,940
One head in a bonus room or garage with a short line set sits near the low end. Longer runs, a condensate pump, line set covers and larger capacity push it higher. Multi-zone systems are priced per project and cost more in total, though often less per room than separate single zones. You get the price before scheduling.

- Number of zones
- Each added head brings more line set, wiring and labor, and the outdoor unit grows with the total capacity.
- Head style
- High-wall heads cost least. Floor consoles, ceiling cassettes and slim ducted units cost more but suit some rooms better.
- Line set length and route
- A run along an outside wall is simpler than one through finished space or up two stories.
- Electrical work
- Most homes need a dedicated circuit and disconnect, and some older panels need more than that.
- Wall and finish type
- Plaster and brick take more care to drill and patch than drywall and vinyl siding.
How a mini-split installation goes
We walk the space with you
We talk about how you use the room, where furniture goes and how you want the heads and line covers to look.
You get a layout and a price
We mark head positions, the line set route and the outdoor unit spot, and give you the installed price.
Installation day
Most single-zone jobs take one day. We mount the heads, drill the wall openings and run the line set, drain and wiring.
Pressure test, vacuum and charge
We pressure test the joints, pull a deep vacuum, release the refrigerant and test heating and cooling in every zone.
Remote and filter walkthrough
We show you the remote, the filter screens and the settings that keep the heads running quietly and efficiently.
When a ductless mini-split is the right call
A bonus room over the garage
Rooms above garages sit under hot roofs and over unconditioned space, and long duct runs rarely keep up.
A sunroom or enclosed porch
All that glass means fast heat gain in summer and fast loss in winter, which suits a dedicated zone.
An older home with no duct space
Bungalows with plaster walls and shallow attics can get whole-house comfort without tearing into walls.
A garage or workshop
A mini-split heats and cools a workspace without tying it into the house air or its ductwork.
Window units you are tired of
Several noisy window units can come out in favor of quiet heads and one outdoor unit out of sight.
An addition or converted space
A new room, finished basement or in-law suite can get its own zone without upsizing the central system.
Ductless installations around Birmingham
In Avondale, Forest Park and Norwood, ductless systems let owners of historic homes add comfort without dropping soffits through original plaster and trim. We route line sets along the least visible exterior wall and use paintable covers. In Ensley and Woodlawn, many older homes are trading their window units for ductless heads.
In Hoover, Chelsea and Trussville, the usual request is a bonus room over the garage that runs several degrees warmer than the rest of the second floor. Homewood cottages with kitchen or bedroom additions are another frequent fit. The original system rarely stretches to the new space. Our base on 15th Avenue North sits close to Woodlawn and Crestwood.
Areas we cover most often
We repair and replace equipment from these manufacturers, plus most other makes.
Questions about ductless mini-split installation in Birmingham
Yes, with a multi-zone system or several single-zone systems sized room by room. Whole-house ductless works well in older bungalows without duct space. In homes that already have usable ducts, a ducted heat pump is usually simpler, with ductless saved for the rooms the ducts cannot reach.
Each head collects condensate from the air and drains it through a small tube that runs with the line set. Where gravity works, it drains outside. Where it cannot, such as on an interior wall, a small condensate pump lifts it to a drain. We plan that route before installation.
They do, and inverter units are good at it because they run longer at low speed, which gives the coil more time to pull moisture out of the air. Many models also have a dry mode for muggy spring and fall days when cooling is barely needed.
We route the line set on the least visible exterior wall where possible and enclose it in a paintable cover that matches the trim or siding. Inside, only the head and a small wall plate show. On brick, we plan the exit point so it lines up neatly with the head.
In most cases, yes. A mini-split is a heat pump, so it heats efficiently through most of a Birmingham winter and keeps working during cold snaps, with output tapering on the coldest nights. Cold-climate models hold their heat better at low temperatures if a room relies on them alone.
Rinse or vacuum the head filters every month or two during heavy use, keep the outdoor unit clear of leaves and mulch, and schedule a yearly professional cleaning of each head's coil and blower wheel. Skipped cleanings are the main reason heads start to smell or drip.
