A 1.5 ton AC unit provides roughly 18,000 BTU of cooling capacity, a common size for larger rooms or small homes when properly matched to the space. In this category, you’ll find 1.5-ton condensers and systems from leading HVAC brands, designed for efficient, reliable cooling.

Typical applications for 1.5 ton AC units include:

Large living rooms or open-plan spaces
Small single-story homes or apartments
Small retail or office suites

Use these sizes as a starting point only—the right tonnage depends on climate, insulation, windows, and ductwork. Your HVAC contractor should confirm system sizing before you order equipment.

A 2-ton AC unit (24,000 BTU) is a popular size for small to mid-sized homes and larger open spaces when properly sized. This category includes 2-ton condensers, air handlers, and complete systems from brands like Carrier, Rheem, Goodman, GrandAire, and Ameristar, giving you multiple options at different efficiency levels.

A 2-ton AC unit is commonly used for:

Homes or apartments around ~900–1,200 sq ft in typical conditions
Open floor plans where a smaller unit can’t keep up
Residential and light commercial spaces needing efficient, reliable cooling

Keep in mind that tonnage is just one part of system design. Insulation, climate zone, duct layout, and window exposure all affect the right size. Have your HVAC professional confirm the correct capacity before ordering equipment.

A 2.5 ton AC unit delivers about 30,000 BTU of cooling power and is often used in mid-sized homes or larger single-story layouts. In this 2.5 TON category, you’ll find condensers, air handlers, and complete systems from brands like Carrier, Goodman, GrandAire, Ameristar, and Rheem, including straight cool and heat pump options.

Typical uses for a 2.5 ton AC unit:

Homes around ~1,000–1,500 sq ft under average conditions
Larger residential zones where 2 ton systems fall short
Small offices and light commercial suites

For best results, pair your 2.5 ton condenser with a properly matched air handler or coil and have your HVAC technician confirm sizing with a load calculation.

A 3 ton AC unit (36,000 BTU) is one of the most common sizes for full-home cooling in typical single-family houses. This 3 TON category lets you compare 3 ton condensers, packaged units, air handlers, and complete systems from trusted brands, with options for different SEER2 ratings and refrigerants.

3 ton AC units are frequently used for:

Homes around ~1,200–1,800 sq ft in average conditions
Light commercial suites, offices, and small retail spaces
System change-outs where an existing 3 ton system is being replaced

Keep in mind that tonnage is only a rule of thumb. Climate, insulation, duct design, and window area can all push you up or down a size, so always have a qualified HVAC professional confirm the right capacity before ordering.

3.5 ton AC units provide about 42,000 BTU of cooling power, bridging the gap between standard residential sizes and heavier-duty systems. This category highlights 3.5 ton condensers, split systems, and packages designed for larger homes and light commercial applications where 3 ton systems may not be enough.

Common applications for 3.5 ton AC units:

Homes roughly in the 1,600–2,000 sq ft range under typical conditions
Multi-story homes with higher cooling loads
Small commercial or office spaces with greater occupancy or internal heat

Because 3.5 ton systems sit near the top end of residential capacity, proper duct design and airflow are especially important. Work with your HVAC contractor to confirm sizing and compatibility between the condenser, air handler, and existing ductwork.

A 4 ton AC unit (48,000 BTU) is built for larger homes and small commercial spaces that need serious cooling capacity. In this 4 TON category, you’ll find 4 ton condensers, split systems and packaged units from major brands, with a range of SEER2 efficiencies and refrigerant options.

Typical uses for 4 ton AC units include:

Homes around ~1,800–2,400 sq ft under average conditions
Larger single-story homes with open layouts
Light commercial spaces, offices or retail suites

Proper sizing and installation are critical at this capacity. Work with your HVAC contractor to verify that a 4 ton unit is appropriate for your load, duct system and electrical service.

5-ton and larger AC units deliver 60,000 BTU of cooling capacity and up, making them a fit for large homes, multi-zone residential projects, and light commercial buildings. This category showcases high-capacity condensers, split systems, and packaged units engineered for demanding cooling loads.

Common applications for 5 ton and larger AC units:

Homes roughly in the 2,400–3,000+ sq ft range under typical conditions
Multi-story houses with higher heat gain
Offices, small retail stores, and other light commercial spaces

At these capacities, a proper load calculation, duct design, and electrical planning are essential. Coordinate with your HVAC contractor or engineer before purchasing to confirm the right tonnage, configuration, and match between indoor and outdoor units.
