How to Choose an Air Conditioner by Area and Heat Gains (Apartment/Office/Store) in Glendale

Choosing the right air conditioner is not only about room size. For stable comfort and reasonable electricity bills, you must match the unit to the cooling load: floor area plus heat gains from people, sunlight, equipment, and ventilation. In Glendale, warm seasons and strong sun can make undersized systems run nonstop, while oversized units short-cycle, dehumidify poorly, and wear out faster. Start with the room area. A quick estimate is about 20–25 BTU per sq ft for typical ceiling heights and average insulation. Then adjust for conditions: add capacity for large windows, south/west exposure, top-floor rooms, poor insulation, or frequent door opening (common for stores). Reduce slightly for shaded rooms, new insulation, or low-occupancy spaces. Next, count heat sources. People add heat, so plan extra capacity for meetings or busy retail hours. Offices and shops often need more cooling due to computers, lighting, refrigerators, and other equipment. Kitchens or server corners require special attention. Ventilation and fresh-air intake also raise the load, especially in commercial spaces. Typical guidance: apartments often fit wall-mounted split or multi-split systems; offices may need multiple zones or ducted solutions for even distribution; stores benefit from higher capacity and better airflow to handle door traffic. Always check electrical limits, noise levels, and placement for proper drainage and service access. For accurate sizing, an HVAC professional can perform a load calculation and recommend the best SEER/EER efficiency, inverter technology, and zoning.
