The best cheap split system air conditioner depends on room size, electrical supply, and whether you need heating as well as cooling. ROVSUN is a strong fit for buyers seeking a 9,000-BTU, 115V option with a listed installation kit. GarveeHome suits smaller spaces, while Albott, Rellytech, and CAAIR offer 12,000-BTU models for larger rooms. Compare capacity and voltage before choosing; listed coverage estimates vary and should not replace a room-by-room sizing assessment.
| Product | Best For | Capacity | Voltage |
|---|---|---|---|
| ROVSUN | Value-focused smaller-room buyers | 9,000 BTU | 115V |
| GarveeHome | Smaller rooms and multiple operating modes | 9,000 BTU | 230V |
| Albott | App control and self-cleaning features | 12,000 BTU | Not stated in supplied details |
| Rellytech | 12,000-BTU heating and cooling | 12,000 BTU | 115V/110V |
| CAAIR | Higher listed efficiency and app control | 12,000 BTU | 115V |
ROVSUN 9,000 BTU Mini Split
ROVSUN is best for buyers who want a compact 115V ductless system with heating, cooling, and a listed installation kit. The product information specifies 9,000 BTU, 20 SEER, a heat pump, and coverage up to 400 square feet. Remote-control functions include fan-speed selection, sleep, timer, ECO, Turbo, and mute modes.
- Why it was selected: Its 115V rating and 9,000-BTU capacity make it a practical option to compare for smaller spaces where the electrical supply matters.
- Limitation: The listed coverage is an estimate; confirm room sizing and electrical requirements before purchase. The product details ask buyers to confirm voltage.
GarveeHome 9,000 BTU Mini Split
GarveeHome is best for smaller spaces where a buyer wants both heating and cooling plus several operating modes. This 230V system lists 9,000 BTU for cooling and heating and a 17 SEER2 rating. Its modes include Cool, Heat, Dry, Fan, and Turbo, with ECO operation, remote-based IFEEL sensing, three fan speeds, and vertical and horizontal airflow adjustment.
- Why it was selected: Its range of modes and adjustable airflow gives buyers more control than a basic cooling-only unit.
- Limitation: The supplied description gives two different coverage figures: up to 252 square feet in the detailed specifications and up to 450 square feet in the product name. Verify appropriate sizing and note that it requires 230V.
Albott 12,000 BTU Mini Split
Albott is best for buyers interested in app control and self-cleaning alongside heating and cooling.

- Limitation: The supplied product details do not specify voltage. Confirm the electrical requirements and room-size suitability before ordering.
Rellytech 12,000 BTU Mini Split
Rellytech is best for buyers comparing a 12,000-BTU heat pump with a stated 115V/110V supply. It lists 12,000 BTU cooling and 12,500 BTU heating, a 19 SEER2 rating, and coverage up to 750 square feet. Four modes—cooling, heating, fan, and dry—are paired with ECO operation, four fan speeds, and a 90-degree vertical swing.
- Why it was selected: Its stated voltage and separate heating and cooling capacities help buyers compare it with other 12,000-BTU options.

CAAIR 12,000 BTU Mini Split
CAAIR is best for buyers who prioritize a listed SEER2 20 rating and want app control. This 115V, 12,000-BTU system is described as covering up to 750 square feet.

Buying Guide: How To Choose A Cheap Split System Air Conditioner
What capacity is right for the room?
Start with the room’s square footage, but do not choose by coverage claims alone. Ceiling height, insulation, windows, sunlight, climate, and room layout can change the capacity needed. The products here range from 9,000 to 12,000 BTU, and their stated coverage figures are not consistent across listings. Seek a proper sizing recommendation if the space is difficult to assess.
Does the voltage match your electrical supply?
Check the product’s electrical requirements before buying. ROVSUN and CAAIR list 115V, Rellytech lists 115V/110V, and GarveeHome lists 230V. Albott’s supplied details do not state voltage. Do not assume that a system will work with an existing outlet; confirm the required circuit and installation needs.
Which features are worth comparing?
- Heating: Choose a heat-pump model if you need both heating and cooling from the system.
- Efficiency: Compare stated SEER or SEER2 ratings, while recognizing that actual energy use depends on conditions and operation.
- Controls: Timer, sleep, ECO, remote sensing, and app features differ by model. Select the controls you will use.
- Installation: Check what the listing says about installation kits, pre-charged components, and professional requirements. Do not assume “easy installation” means no specialized work is needed.
