DIY-friendly ductless heat pumps for rooms, garages, and additions — every listed model is 115V~/60Hz/1P, with WiFi + Alexa and free single-box shipping.
Is a 115V system big enough for your room?
The free what size mini split do I need calculator checks cooling and heating, then matches a model.
A 110V mini split (also searched as 115V mini split or 120V mini split) is a ductless inverter heat pump that runs on standard single-phase residential voltage — on Classic America systems, the published rating is 115V~/60Hz/1P. That makes these units an appealing path for smaller rooms, offices, garages, and additions when you want cooling and heating without stepping up to a 230V circuit.
This hub lists every Classic America / Vtronix single-zone model that is truly 115V on the live product pages: the 9,000 BTU 23 SEER2, the 12,000 BTU 19 SEER2, and the 12,000 BTU 17 SEER2. Larger systems (23,000 BTU and the DUET two-zone) use 208/230V and live on the full mini-split category.
Many homeowners treat a DIY mini split install as a hybrid project — mounting, line-set routing, and outdoor placement — while leaving refrigerant and electrical connections to a licensed HVAC pro. Every system here ships free in one box (indoor + outdoor + install kit). Need a size match first? Use the size finder, or call 1-800-349-4360 Ext. 204 (Mon–Fri, 10 AM–3 PM ET).

110V vs 115V vs 120V — what's on the panel
110V, 115V and 120V all describe the same standard household supply. The nameplate on the outdoor unit and its manual set the circuit requirements; a licensed electrician should confirm your panel before install.
115V · often called 110V / 120V
Standard household voltage
For bedrooms, offices, garages and additions. Many homes can skip a new 230V circuit at these capacities; a licensed electrician should still confirm circuit capacity.
208/230V · often called 240V
Dedicated 230V circuit
For large open areas and two-zone setups. Plan a dedicated 208/230V circuit with a licensed electrician before you buy.

FAQ
Common questions about 110V mini splits
What is a 110V mini split?
A 110V mini split is a ductless heat pump designed for standard residential single-phase power. Classic America's 9,000 and 12,000 BTU models publish 115V~/60Hz/1P on the product pages — the same class often called 110V or 120V. Shop them on this hub or see all mini splits.
Is 110V the same as 115V or 120V?
In homeowner language, yes — people use 110V, 115V, and 120V interchangeably for standard household circuits. Always follow the voltage printed on the outdoor unit nameplate and the product specifications. Our listed models are 115V~/60Hz/1P.
Can I install a DIY mini split on 115V power?
Many homeowners handle mounting and line-set routing. Refrigerant work and electrical connections should be done by a licensed HVAC professional. Use the install planner and delivery & installation guide before you order.
Which Classic America mini splits are 110V / 115V?
Three single-zone systems: 9,000 BTU 23 SEER2, 12,000 BTU 19 SEER2, and 12,000 BTU 17 SEER2 — all 115V~/60Hz/1P. The 23,000 BTU and DUET systems require 208/230V.
When should I choose 230V instead?
Choose 230V / 208-230V when you need higher capacity (e.g., larger open areas or two zones). See the 23,000 BTU and DUET pages, or start with the size finder.
