Ductless Mini-Split Installation, Repair & Maintenance in Fort Worth, TX
Room-by-room comfort without the ductwork. Innovative Air installs, repairs, and maintains ductless mini-split systems for garages, room additions, home offices, sunrooms, and older DFW homes.
What Is a Ductless Mini-Split?
A ductless mini-split is a highly efficient heat pump made of two parts: a slim outdoor condenser and one or more indoor units mounted on a wall, ceiling, or floor. Refrigerant lines the diameter of a garden hose connect the two — no bulky ductwork, no torn-up drywall, and no losing 20–30% of your conditioned air to duct leakage.
Every indoor head cools and heats the room it serves, independently. That means you can keep the master bedroom at 70°F, the home office at 74°F, and the garage workshop at 68°F — all from the same outdoor unit, all running only as hard as each zone actually needs. It's the same inverter-driven technology used in commercial-grade LG VRF systems, scaled down for homes and small commercial spaces.
As LG VRF specialists in Fort Worth, mini-split work is a natural extension of what we do every day. The refrigerant piping practices, load calculations, commissioning, and controls setup are the same disciplines — just at a residential scale. That background is what separates a mini-split that runs quietly for 20 years from one that limps along and fails at year seven.
Mini-Split or VRF — Which Do You Need?
Mini-splits and VRF systems come from the same family. The right choice depends on the size of your project, how many zones you need, and whether it's a home or a commercial building.
| Consider a… | Mini-Split | VRF System |
|---|---|---|
| Best for | Homes, garages, additions, small offices | Custom homes, offices, retail, multi-tenant buildings |
| Zones | 1–5 indoor units | Up to 30+ indoor units per condenser |
| Simultaneous heat + cool | No (whole system heats or cools) | Yes (heat-recovery models) |
| Typical use | Spot cooling, room-by-room retrofits | Whole-building comfort with advanced controls |
| Investment | $3,500–$18,000 installed | $25,000–$250,000+ depending on scale |
Not sure which fits your project? We'll walk your home or building, do the load calculation, and give you a straight answer — even if that answer is "keep the central AC you already have and add one mini-split for the addition." Learn more about our VRF systems for larger projects.
Benefits of Ductless Mini-Splits
Why Fort Worth homeowners choose ductless over adding to their central system.
Extreme Efficiency
18–30 SEER2 ratings and zero duct loss — real energy savings 30–50% versus adding on to a central system.
True Zoned Comfort
Each room set to its own temperature. No more hot back bedroom or cold sunroom.
Heat + Cool In One Unit
Every mini-split we install is a heat pump — cooling in July, heating in January, same equipment.
No Ductwork Needed
Perfect for additions, sunrooms, garages, and older homes that can't easily accept ducts.
Whisper-Quiet
Indoor units as low as 19 dB. You'll forget they're running.
Fast Installation
Most single-zone mini-splits are installed and running the same day — no wall demo, no drywall repair.
Mini-Split Installation in Fort Worth
A mini-split will only last as long as the install allows. Every project — even a single-zone garage unit — gets the same disciplined process we bring to commercial VRF work.
- 1
Load Calculation
We calculate the actual heat gain / loss of the space using Manual J principles — not a rule of thumb — so the equipment is sized right. Oversized mini-splits short-cycle and dehumidify poorly; undersized ones run non-stop.
- 2
Location & Line-Set Planning
We walk the space with you to place the indoor head where airflow works, the outdoor unit where it's serviceable and quiet, and route the line set with the shortest, cleanest path.
- 3
Professional Installation
Wall-bracket mounting, refrigerant line brazing, pressure test, deep vacuum evacuation, condensate routing, low-voltage controls, and neat exterior line-set covers. Typical single-zone install is one day.
- 4
Commissioning & Testing
Refrigerant charge verified by weight, superheat/subcool measured, airflow checked at every head, and the remote/app paired and tested.
- 5
Warranty Registration
We register your equipment with LG, Mitsubishi, or Daikin for the full 10-year parts and compressor warranty — and back the labor with our own workmanship guarantee.
Mini-Split Repair in Fort Worth
Mini-splits are reliable, but they still fail — usually because of installation shortcuts, dirty filters, or a bad control board. We repair all major brands, including systems installed by other contractors.
Indoor unit not cooling / heating
Refrigerant leak, blocked coil, or a failed indoor blower — we diagnose with pressures and temperatures, not guesswork.
Blinking lights or error codes
Every brand has its own error-code language. We read them, look them up, and fix the actual failure — not just clear the code.
Water leaking from indoor head
Almost always a clogged condensate line or a failed pump. We clear it and check the pitch of the line so it doesn't come back.
Outdoor unit not running
Bad capacitor, failed inverter board, blown fuse, or a low-voltage communication fault. We carry common LG and Mitsubishi parts on the truck.
One zone works, others don't
Multi-zone systems can have branch-controller or refrigerant-distribution issues that a general HVAC tech won't spot.
Ice on refrigerant lines
Low charge, dirty filter, or a failing metering device. We find the root cause before recharging.
Need same-day service? Our AC repair team covers ductless as well as central systems, and emergency dispatch is available across DFW.
Mini-Split Maintenance in Fort Worth
Ductless mini-splits can easily last 15–20 years — but only if the indoor coils stay clean and the refrigerant charge stays right. Skip maintenance and you'll see reduced cooling, higher bills, mold on the blower wheel, and shortened compressor life.
- Twice-yearly professional inspections (spring + fall)
- Indoor unit filter service and coil cleaning at every head
- Blower wheel deep-clean when needed (a common source of musty odors)
- Outdoor condenser coil rinse and clearance check
- Refrigerant charge and superheat/subcool verification
- Condensate line clearing and pump testing
- Electrical inspection: capacitors, contactors, control boards
- Priority scheduling and discounted labor for plan members

Best Applications for Ductless Mini-Splits
These are the projects where a ductless mini-split almost always beats extending central AC.
Garage Mini-Split
Turn an uninsulated Texas garage into a year-round workshop, gym, or hobby space. Handles the high heat gain from garage doors.
Home Office Mini-Split
Keep your remote-work office comfortable without freezing out the rest of the house. Independent thermostat, whisper-quiet operation for calls.
Room Addition Mini-Split
Additions almost never have enough duct capacity to cool properly. A mini-split solves it in a day with no drywall damage.
Sunrooms & Enclosed Porches
Sunrooms are heat magnets. A right-sized mini-split makes them usable through DFW summer afternoons.
Older Homes Without Ducts
Historic and pier-and-beam homes are perfect candidates — no invasive duct installation, no soffit drops, no ceiling damage.
Attic Conversions & Bonus Rooms
Second-story bonus rooms and finished attics are notorious for being 10°F warmer than the rest of the house. A dedicated mini-split fixes it.
Small Commercial Spaces
IT closets, break rooms, small retail spaces, and back-of-house offices where central HVAC isn't cost-effective.
Guest Suites & In-Law Apartments
Independent zone control for spaces used only part of the time — heat or cool on demand instead of running the whole house.
Hot / Cold Room Fixes
Kitchens, west-facing bedrooms, and rooms far from the air handler often need a dedicated head to hold temp in July.

Ductless Mini-Split Frequently Asked Questions
What is a ductless mini-split system?
A ductless mini-split is a two-piece heat pump: a slim outdoor condenser connected by refrigerant lines to one or more wall-, ceiling-, or floor-mounted indoor units. Each indoor head cools and heats the room it's mounted in, with no ductwork required. You get precise, room-by-room comfort without cutting into walls for supply and return ducts.
How is a mini-split different from a VRF system?
They're built on the same inverter-driven heat-pump technology. A mini-split is the residential, smaller-scale version — typically one outdoor unit with one to five indoor heads. A VRF (Variable Refrigerant Flow) system is the commercial-grade cousin: larger capacity, more zones (often 20+ indoor units on a single condenser), advanced heat-recovery, and a more sophisticated controls network. Because we're LG VRF specialists, mini-split installs are a natural extension of what we already do every day.
Are ductless mini-splits good for Texas summers?
Yes. Modern inverter-driven mini-splits are rated to deliver full cooling capacity in ambient temperatures well past 105°F. In Fort Worth, they hold setpoint in July and August without the short-cycling and hot spots you get from a single-stage central AC.
How much does a mini-split installation cost in Fort Worth?
A single-zone mini-split for a garage, office, or bonus room typically runs $3,500–$6,500 installed. Multi-zone systems (2–5 indoor heads on one outdoor unit) generally range $7,500–$18,000 installed, depending on capacity, brand, and line-set complexity. We give firm, itemized quotes after an on-site load calculation — never a phone guess.
How long do mini-splits last?
A professionally installed and maintained mini-split typically lasts 15–20 years, and premium LG or Mitsubishi systems often go longer. The inverter compressor runs at partial load most of the time, which means far less mechanical stress than a conventional AC that cycles on and off at full power.
Can a mini-split heat my space in winter?
Yes. Every mini-split we install is a heat pump, so it delivers both cooling and heating from the same equipment. Modern cold-climate models still produce useful heat down to about 5°F — well below anything a Fort Worth winter throws at us.
Do mini-splits work well in garages?
Garages are one of the best applications. A single 12,000–24,000 BTU wall unit turns an uninsulated Texas garage into a usable workshop, gym, or hobby space year-round. We handle the higher heat gain from garage doors and lack of insulation in the sizing calc.
Can I put a mini-split in a room addition or sunroom?
Absolutely — that's one of the most common reasons homeowners call us. Room additions, sunrooms, and converted attics rarely have enough duct capacity to serve a new space, and running new ducts is expensive or impossible. A mini-split solves the problem in one day with no drywall damage.
How energy-efficient are mini-splits?
Very. Most quality mini-splits run 18–30 SEER2, compared to 14–16 SEER2 for standard central AC. Because there's no duct loss (typical ducted systems lose 20–30% of their conditioned air), real-world efficiency is even better than the label suggests.
How often do mini-splits need maintenance?
At minimum once a year, ideally twice — spring and fall. Indoor unit filters need frequent cleaning (monthly during heavy use), coil cleaning annually, and outdoor unit inspection, refrigerant verification, and condensate line service every year. Maintenance plans lock in priority scheduling and reduced labor rates.
Can you repair a mini-split installed by another company?
Yes. We diagnose and repair LG, Mitsubishi, Daikin, Fujitsu, Samsung, and other major mini-split brands regardless of who installed them. Bring us the model numbers on the outdoor and indoor units and we'll get it back up.
Are mini-splits loud?
No — they're one of the quietest HVAC options available. Indoor heads run as low as 19–26 dB (quieter than a whisper) and outdoor units are significantly quieter than a traditional central AC condenser.
What brands of mini-splits do you install and service?
We install and service LG, Mitsubishi Electric, and Daikin as our primary brands. We also repair Fujitsu, Samsung, and other major manufacturers already in the field. We do not install off-brand or unbranded imports — parts and warranty support aren't there.
Do mini-splits come with a warranty?
Yes. LG, Mitsubishi, and Daikin all offer 10-year limited warranties on parts and the compressor when installed by a certified contractor and registered promptly. We handle registration for you and back our labor with our own workmanship warranty.
What service areas do you cover for mini-split installation?
Fort Worth, Dallas, Arlington, Mansfield, Burleson, Keller, Southlake, Colleyville, Grapevine, North Richland Hills, Hurst, Euless, Bedford, and the surrounding Dallas–Fort Worth metroplex.
