Proper heat pump sizing depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate factors. A system that’s too small won’t keep you comfortable, while an oversized unit wastes energy and creates humidity problems. Our technicians perform detailed load calculations using industry-standard methods to determine the exact capacity needed. We measure your home, assess insulation, evaluate sun exposure, and consider your family’s comfort preferences. Most North Fair Oaks homes need between 2-5 tons of cooling capacity, but every home is different. We’ll provide a precise recommendation based on your specific needs, not generic estimates.
