Buying Guide for Mini Split Systems for 1200 Sq Ft Homes

When selecting a mini split system for a 1200 square foot house, consider these key factors:

  • BTU Capacity and Coverage: Ensure the unit(s) provide sufficient BTUs to handle 1200 sq ft comfortably. Single units around 18,000–24,000 BTU or multi-zone systems with combined capacities near 27,000 BTU work well.
  • Energy Efficiency (SEER2 Rating): Higher SEER2 ratings translate to better energy savings. Aim for units with 17 SEER2 or higher for reduced electricity bills.
  • Heating Functionality: Heat pumps with low-temperature capabilities are beneficial for year-round use, especially in cooler climates.
  • Smart Features and Connectivity: WiFi, Alexa, or Google Assistant compatibility enable remote control and automation, enhancing convenience.
  • Installation Considerations: Check whether the system is pre-charged and if professional installation is recommended or required, especially for multi-zone units.
  • Environmental Impact: Refrigerants like R32 are more eco-friendly than older types, improving indoor air quality and minimizing environmental harm.
  • Multi-Zone vs Single-Zone: Multi-zone systems allow for individual temperature control in multiple rooms, ideal for varied user preferences and energy savings.

Take into account your home’s layout, climate zone, and personal comfort preferences to select the best mini split system.
