Transparent Pricing Guide by Yeti Cooling & Heating

If your system is past its prime, you’re probably wondering:

“How much should I expect to spend on a new HVAC system?”

At Yeti Cooling & Heating, we believe San Antonio homeowners deserve clear, honest pricing. Below, we break down average replacement costs by tonnage, plus the key factors that affect your total investment.

📏 What “Tonnage” Really Means

Tonnage refers to cooling capacity — not weight.

1 Ton = 12,000 BTUs/hour of cooling
Most San Antonio homes need 2–5 tons depending on size, insulation, and layout.

💵 Average HVAC Replacement Cost in San Antonio (By Tonnage)

System Size (Tons)	Typical Home Size	Estimated Cost Range
2 Ton	Small homes / condos	$10,000 – $14,000
3 Ton	1,800 – 2,500 sq ft	$11,000 – $15,000
4 Ton	2,500 – 3,000 sq ft	$12,000 – $16,000
5 Ton	3,000 + sq ft	$13,000 – $17,000 +

💡 Prices reflect full system replacement (equipment + labor) assuming existing ductwork is in good condition.

⚙️ What Drives HVAC Replacement Cost?

1️⃣ Efficiency (SEER2 Rating)

Higher-efficiency units (16–18 SEER2) cost more upfront but cut energy bills for years.

2️⃣ Ductwork Condition

Leaky or undersized ducts may add $2,000–$3,000 per ton for repair or replacement.

3️⃣ Installation Complexity

Attic installs, tight spaces, or electrical upgrades can increase labor time.

4️⃣ Permits & Local Codes

City permits and inspections keep your system safe & compliant and are included in your Yeti quote.

5️⃣ Timing & Labor Demand

Schedule during spring or fall (off-peak) for the best pricing.

6️⃣ Add-Ons & Upgrades

Smart thermostats, UV lights, and air purifiers improve comfort and IAQ but raise cost slightly.

🧠 How to Compare Quotes the Smart Way

When reviewing multiple estimates, confirm each includes:✅ Brand & model numbers✅ SEER2 efficiency rating✅ Ductwork scope (repair / replace / reuse)✅ Permit & inspection fees✅ Labor & parts warranty coverage

If one quote seems too low, dig deeper — missing components or unpermitted installs can cost more later.
