Buying Guide For Mini Split Air Conditioners For 800 Sq Ft Areas
Cooling Capacity (BTU and Zone Design)
Select a mini split air conditioner with a cooling capacity that covers your total square footage efficiently. For 800 sq ft, units typically range between 12,000 to 18,000 BTU. Dual zone systems provide individual controls for two separate rooms, ideal for divided spaces, while single-zone units cover open areas or one large room.
Energy Efficiency (SEER2 Rating)
A higher SEER2 rating means better energy efficiency and potentially lower electricity bills. Look for systems rated above 17 SEER2 for modern inverter mini splits, with some models offering 19 to 22 SEER2, balancing efficiency with cooling power.
Heating Capability and Heat Pump Performance
Many mini splits also provide heating using heat pumps. Check the lowest outdoor temperature rating supported by the unit’s heat pump if you live in colder climates. For year-round comfort, units with robust heat pumps and inverter technology ensure both heating and cooling are efficient.
Smart Features and Connectivity
WiFi compatibility and Alexa or voice control make operation convenient. Features like timers, sleep modes, and iFEEL temperature sensors help improve comfort and save energy by adapting to your lifestyle.
Installation Kit and Included Components
Proper installation is critical. Choose units that come with pre-charged refrigerant lines and full installation kits for copper piping, drain pipe, and mounting hardware to save time and cost on setup.
Noise Level and Operating Modes
Check for quiet operation, especially if the unit will be installed in bedrooms or offices. Multiple modes like dry, turbo, eco, and fan speed options provide flexible climate control to meet different seasonal and occupant needs.
Refrigerant Type
Eco-friendly refrigerants like R32 reduce environmental impact and improve energy efficiency compared to older refrigerants.
