Fix Hot and Cold Spots With a Ductless Mini Split in Durham, NC
A ductless mini split adds heating and cooling to a room that doesn't have ductwork, and fixes hot or cold spots by giving that space its own zone and its own thermostat. We design and install single zone and multi zone systems across Durham, sized and set up correctly for the room they're actually going into.
Ductless Mini Split Specialists in Durham
We design and install ductless systems for homes and businesses across Durham, single zone or multi zone, wall mount, ceiling cassette, or floor mount depending on what the room actually calls for. Every install starts with a real load calculation per zone, not a head pulled off the truck because it’s close enough. And every system gets commissioned to spec before we consider the job finished, not just plugged in and left to run.
Our Ductless Mini Split Services
Single Zone Mini Splits
One room, one problem, one fix. Works well for an addition, a converted garage, or a home office that's never quite matched the rest of the house.
Multi Zone Mini Splits
More than one room needs its own answer? A multi zone setup runs several indoor heads off a single outdoor unit, so nobody's fighting over one thermostat trying to please the whole house at once.
Ductless for Historic and Older Homes
Plenty of the older houses around Old West Durham and Trinity Park were built long before central ductwork was standard, and retrofitting full ducts into those walls gets expensive and invasive fast. Ductless skips that problem entirely.
Mini Split Repair and Maintenance
Weak airflow out of a head. Water pooling under an indoor unit. An outdoor unit icing over when it's 60 degrees outside. We repair existing systems too, not just install new ones.
How We Handle a Ductless Installation
1. You Schedule a Visit
Call us or book online, and we'll set a time to actually see the room in person.
2. We Size the Zone Properly
A real Manual J load calculation for each zone, plus a look at head placement and how the line set will route through the wall.
3. You Get a Clear Recommendation
Wall mount, ceiling cassette, or floor mount, whichever actually fits the space, with a real price attached before anything gets ordered.
4. We Install It Right
Dedicated electrical circuit and disconnect, clean line set routing, proper condensate management, and whatever inspections the job requires.
5. We Commission the System
efrigerant charge, superheat and subcool, airflow balance, and condensate pump operation, all checked before we call it done. Not just switched on and left running.
Why Durham Homeowners Choose Alternative Aire for Ductless
Real Load Calculations, Not Guesswork
We run a Manual J for every zone instead of eyeballing a room and guessing at head size, which is where a lot of ductless installs go wrong before they even start.
No Ductwork Required
ust a small wall penetration and a line set cover that's easy to hide. No tearing into walls to force ductwork into a room that was never built for it.
Licensed, NATE Certified, 17+ Years in Durham
Fully licensed under NC H2 and H3-Class 1 #30223, BBB A+ Accredited, and every technician on our team NATE certified
Full Commissioning, Every Time
Refrigerant charge, superheat and subcool, airflow balance, condensate pump operation, all verified before we leave. A lot of installers skip this step. We don't.
Multiple Brands, No Pressure
We install Mitsubishi, Daikin, Fujitsu, LG, and Gree, so you get the system that fits your room and your budget, not whatever's sitting on the truck.
Financing for Your Ductless Mini Split
A full mini split setup isn’t cheap, especially once you’re covering more than one zone, and we’re not going to pretend otherwise. We offer financing through the Wells Fargo Home Projects Credit Card, which covers installation and repairs both, so you can get the room fixed now instead of waiting around to save up for it. Same application either way, no runaround, and one less reason to keep living with a room that’s never actually comfortable.

Ductless Mini Split FAQs
How is a ductless mini split different from central air?
A mini split cools or heats specific rooms directly, wall or ceiling mounted heads tied to an outdoor compressor, no ducts involved anywhere. Central air moves conditioned air through a shared duct system for the whole house. If you’re trying to fix one or two rooms rather than replace a whole home system, ductless is usually the better call.
Can it work in a home with no existing ductwork at all?
That’s actually the main reason a lot of people choose it. Plenty of the older homes around Old West Durham and Trinity Park were never built for central ductwork, and ductless just sidesteps the whole problem.
How many zones do I actually need?
Depends on what you’re solving for. One room that’s always uncomfortable usually just needs a single zone. An addition plus a bonus room, or a whole floor running warm or cold, typically calls for a multi zone. We’ll look at the space before recommending either one.
What brands do you install?
Mitsubishi, Daikin, Fujitsu, LG, and Gree. We’ll recommend based on the room and the budget, not push a single house brand.
Does installation require an electrical permit?
Usually, yes. Installation includes a dedicated circuit and disconnect, and we handle whatever inspections the job requires as part of the work.
Are these systems actually as quiet as people say?
Pretty much. Indoor heads run at a low enough decibel level that most homeowners forget they’re even on, which is a big part of why they work so well in bedrooms and home offices.
What are the warning signs my mini split needs repair?
Weak heat or cooling from a specific head, water pooling under an indoor unit or repeated drain alerts, an outdoor unit icing over in mild weather, controls that stop responding, or an energy bill climbing with no real change in how you’re using the system.
Is financing available for mini split installation?
Yes, through the Wells Fargo Home Projects Credit Card, and it covers both installation and repair costs
