What Is A 5 Ton AC Unit?

A 5 ton air conditioning unit is a powerful cooling system capable of providing approximately 60,000 BTUs (British Thermal Units) per hour. It’s commonly chosen for large homes (typically 2,500 – 3,200 sq ft) or small commercial spaces. The term “ton” refers to the AC’s cooling capacity, not its weight.

Choosing the correct tonnage ensures efficient cooling, lower energy bills, and improved comfort.

2025 5 Ton AC Unit Cost Breakdown

Equipment: How Much Does The Unit Cost?

The price of the 5 ton AC unit itself varies by brand, efficiency rating (SEER or SEER2), and features. As of 2025:

• Entry-level 5 ton central AC units: $2,800 – $3,700
• Mid-range/high-efficiency units: $3,800 – $5,000
• Premium, variable-speed models: $5,000 – $5,500+

Installation: What’s Included In Full System Costs?

The installed cost includes both equipment and labor. Expect:

• Low end (basic replacement, minimal duct work): $5,800 – $7,500
• Average full-system installation: $7,500 – $9,500
• High end (extensive new ductwork, zoned systems): $10,000 – $11,500+

Installation prices vary based on location, difficulty, and specific home needs.

Main Factors Affecting 5 Ton AC Unit Cost

• Brand and Model: Premium brands like Trane, Lennox, and Carrier cost more than Goodman, Rheem, or American Standard.
• Efficiency (SEER/SEER2 Rating): Higher efficiency lowers electricity bills but increases upfront cost.
• Single vs Variable Speed: Variable-speed compressors are more expensive but quieter and more efficient.
• Home Location: Costs are higher in coastal or urban regions (e.g., Northeast, California, Florida) versus midwestern or southern states.
• Existing Ductwork: Replacing or upgrading ducting significantly increases the total cost.
• Permit & Code Requirements: Compliance with local building codes or specialized electrical work may add to cost.

Labor And Installation Costs Explained

Labor costs for installing a 5 ton AC unit vary widely. On average, expect $2,500 – $5,000 of the total price to cover:

• Removing and disposing of old equipment
• Installing indoor air handler and outdoor condenser
• Connecting refrigerant lines and electrical components
• Testing, charging, and system startup
• Minor ductwork adjustments
• Permits and inspections

Extensive ductwork replacement, electrical upgrades, or zoning can further increase costs.

Cost Of Ductwork For 5 Ton AC Units

A significant factor is the condition and layout of existing ductwork. New ductwork for a 5 ton system averages:

• Basic duct replacement (2,500–3,000 sq ft home): $2,000 – $5,000
• Complex multi-zone or custom applications: $6,000+

Homes with old, leaky, or undersized ducts must budget for these upgrades to ensure the new AC system operates efficiently.

Energy Efficiency And Annual Operating Expenses

How SEER2 Rating Impacts Electricity Costs

5 ton AC units come with varying SEER (Seasonal Energy Efficiency Ratio) and SEER2 ratings. Higher SEER2 means lower energy bills.

• Standard (SEER2 14-16): $1,400 – $1,800/year
• High-Efficiency (SEER2 18-22): $950 – $1,300/year

Upgrading efficiency can save hundreds of dollars annually, especially in hotter climates.

Factors Affecting Operating Cost

• Climate (humidity and average temperatures)
• Home size and insulation quality
• Usage patterns and thermostat settings
• Regular filter changes and maintenance

Features To Consider When Buying A 5 Ton AC Unit

When comparing models, focus on these attributes:

• Compressor Type: Single-stage, two-stage, or variable-speed (variable is quietest and most efficient)
• Smart Thermostat Integration: Compatible models help optimize comfort and savings
• Noise Levels: Variable-speed units run quieter indoors and outside
• Corrosion Protection: Coastal installations require anti-corrosive coatings
• Warranty: Longer warranties reduce risk of future repair expenses

How To Size Your AC: Is 5 Ton Right For Your Home?

Proper sizing prevents issues like uneven cooling, short cycling, or premature wear. Consider:

• Home square footage (usually 2,500–3,200 sq ft for a 5 ton unit)
• Ceiling height, insulation, number of windows
• Regional climate (warmer locations may require more capacity)
• Professional load calculation (Manual J calculation from HVAC contractor)

An oversized unit cools quickly but may not dehumidify properly, while an undersized unit will struggle to keep up.

Replacement Vs. New Installation Costs

Replacing an existing 5 ton unit (using same-size, with compatible ductwork) is less expensive than a first-time install:

• Replacement (basic swap): $5,800 – $8,500
• New system (incl. ducts, new electrical): $8,500 – $12,500

Retrofitting older homes with new ducts, vents, and electrical panels increases both time and labor fees.

Maintenance And Repair Costs

Regular care prevents costly breakdowns. Typical annual maintenance: $120 – $300. This includes:

• System inspection and tune-up
• Refrigerant check
• Cleaning coils and drain lines
• Filter replacement

Common 5 ton AC repairs include capacitor replacements ($200–$350), fan motors ($450–$750), and refrigerant recharge ($250–$650).

Lifetime Value And Total Cost Of Ownership

To evaluate long-term expenses, add up:

• Initial equipment + installation
• Annual electricity usage
• Routine maintenance
• Repairs after 5-7 years

A high-efficiency 5 ton AC might cost $1,000–$2,000 more upfront, but could save $400+ per year in energy, breaking even after just 3-5 years of use.

Financing Options And Tax Credits

Many homeowners utilize HVAC financing plans to spread out costs over 2–10 years. Look for:

• Manufacturer or dealer 0% APR specials
• Home equity lines or credit cards

Federal and state rebates may also be available for high-efficiency models (SEER2 16+), saving $350–$1,200 or more on qualifying systems in 2025.
