10 Best 110 V Mini Split 2025 in the United States

The MRCOOL 12000 BTU 115V Ductless Inverter Mini Split is a solid choice for those needing both heating and cooling in a space up to about 550 square feet. With 12,000 BTUs, it’s well-suited for small to medium rooms like bedrooms, offices, or small commercial areas. It runs on standard 115 volts, which is convenient for most homes without requiring special electrical wiring. The noise level is quite low at 43 dB, meaning it won’t be disruptive during use.

One of its strengths is the all-year-round capability thanks to its heat pump feature, so you get both cooling in summer and heating in winter without needing separate systems. The unit is wall-mounted and part of MRCOOL’s DIY Easy Pro Series, which means installation is designed to be simpler than traditional mini-splits, potentially saving on professional setup costs. The product has a basic 2-star BEE rating, suggesting it may not be the most energy-efficient option available. Also, this model supports only a single zone, so it’s best if you want to climate-control one specific area rather than multiple rooms.

Additional features like a timer mode, refrigerant leak detection, and Active Clean Technology help maintain air quality and convenience. This unit provides a practical, quiet, and easy-to-install solution for modest spaces needing both heating and cooling, though those prioritizing energy savings or multi-zone setups might want to explore other options.

The MRCOOL 18000 BTU Mini Split is designed to efficiently heat and cool spaces up to approximately 800 square feet. With an 18,000 BTU capacity and a high SEER rating of 22.5, it provides strong performance while being energy efficient, helping to keep electricity costs reasonable. Operating quietly at about 46 decibels, it maintains a peaceful environment comparable to the noise level of a quiet conversation.

Installation is simplified by the unit's DIY-friendly design, featuring pre-charged, quick-connect line sets that eliminate the need for special tools or professional help. This wall-mounted system supports one zone, suitable for medium-sized spaces. It includes smart features such as WiFi control compatible with Alexa and Google Assistant for convenient temperature adjustments via smartphone. Additional comfort options like a dehumidifier and sleep mode enhance usability throughout the year.

The unit comes with a robust warranty—5 years on parts and 7 years on the compressor—providing added peace of mind. Potential buyers should note the voltage requirement, which may necessitate proper electrical setup or adaptation depending on the household configuration.

The MRCOOL DIY 5th Gen mini-split is designed for smaller spaces up to about 350 square feet, with a 9,000 BTU cooling and heating capacity, making it a good fit for single rooms or small offices. Its SEER rating of 23.6 shows it is quite energy-efficient, helping to keep electricity costs down while providing reliable comfort year-round. The noise level is moderate at 45 dB, which is generally quiet enough not to be disruptive in most home or office environments.

One of its biggest advantages is the easy DIY installation — the included pre-charged 25-foot line set lets you set it up without professional help, saving on installation fees and time. It supports a single zone, which is typical for units of this size, so it’s best suited for targeted cooling or heating rather than multiple rooms. The unit also offers convenient features like WiFi control, compatibility with voice assistants like Google Assistant and Alexa, and modes like sleep and dehumidifier, adding comfort and usability.

It runs on standard 115 volts which is good for common household outlets, but the 0.75-ton capacity means it won’t be ideal for larger spaces or whole-home use. While the noise level is acceptable, it’s not the quietest option available if ultra-low noise is a priority. This MRCOOL mini-split is a solid choice for users who want an efficient, versatile, and easy-to-install ductless system for a small area, especially those comfortable handling a DIY setup.
