Choosing the right AC size for your Irvine home involves Manual J load calculations, factoring in coastal sun, insulation, and square footage to avoid short-cycling or inefficiency. ARA Heating & Air Conditioning performs precise assessments for optimal tonnage, ensuring comfort in Woodbridge layouts. Proper sizing saves energy near Turtle Rock heat peaks.
Understand Tonnage and Cooling Capacity
AC size measures in tons (12,000 BTU/hour per ton).
- 1,500 sq ft homes: 2-2.5 tons typically.
- 2,500 sq ft near Quail Hill: 3-4 tons.
- Sunny exposures add 10-20% capacity around the Great Park.
- Poor insulation demands upsizing in University Park.
Rule of thumb: 1 ton per 400-600 sq ft, but calculate accurately.
