Why Bigger Isn’t Always Better When It Comes to Cooling Your Space
When it comes to buying a new air conditioner, most homeowners think bigger means better. After all, a larger unit should cool your home faster—right? Not quite.
Choosing the right size air conditioner for your home is one of the most important decisions you’ll make for your comfort, energy efficiency, and long-term savings. At Adam A/C Heating & Refrigeration, we’ve helped countless San Antonio homeowners find systems that are perfectly matched to their homes—and we’re here to help you do the same.
❄️ Why AC Size Matters
An air conditioner that’s too small will run constantly, struggle to cool your home, and wear out faster due to overuse.
An air conditioner that’s too large will cool your home too quickly—without properly removing humidity—leaving you with a cool but clammy feeling and higher energy bills.
The goal is to find the Goldilocks zone—a system that’s just right for your space.
📏 What Factors Determine the Right AC Size?
Choosing the correct AC size isn’t just about square footage. A qualified HVAC technician will consider several important factors, including:
- Home square footage
- Ceiling height
- Number of windows and their orientation
- Home insulation quality
- Ductwork condition
- Local climate (Hot Texas summers, we’re looking at you!)
- Number of occupants and heat-generating appliances
We use industry-standard calculations called Manual J load calculations to ensure every system we install is properly sized—not just guessed.
🔢 What Does AC Size Mean?
Air conditioners are rated in tons or BTUs (British Thermal Units).
1 ton = 12,000 BTUs/hour
Here’s a rough estimate based on square footage:
- 1.5 ton: 600–1,000 sq ft
- 2 ton: 1,000–1,300 sq ft
- 2.5 ton: 1,300–1,600 sq ft
- 3 ton: 1,600–1,900 sq ft
- 3.5 ton: 1,900–2,200 sq ft
- 4 ton: 2,200–2,600 sq ft
- 5 ton: 2,600–3,000 sq ft
Note: These are general estimates. Your actual needs may differ based on insulation, layout, and other home-specific factors.
