The average cost for a 5-ton HVAC system installed is about $12,000, with common total quotes ranging from $8,000 to $18,000. The price depends on whether the work covers central air conditioning alone or a matched heating-and-cooling system, plus equipment efficiency, ductwork, labor rates, and removal needs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 5-ton central AC replacement | $8,000 | $11,500 | $16,000 | Outdoor condenser, indoor coil, standard installation |
| 5-ton heat pump system | $9,000 | $13,500 | $19,000 | Heating and cooling; electrical or duct changes can add cost |
| 5-ton AC with furnace | $10,000 | $14,500 | $21,000 | Matched cooling equipment and gas furnace |
| Equipment capacity | $1,600 | $2,300 | $3,800 | Approximate equipment price per ton, before installation |
What a 5-Ton HVAC Installation Usually Includes
A standard 5-ton central air replacement typically costs $8,000-$16,000 installed when existing ducts, electrical service, and equipment location are suitable. A complete system that also replaces a furnace commonly falls between $10,000 and $21,000. Higher-efficiency equipment and substantial modifications can push a project above that range.
Five tons equals 60,000 BTU per hour of cooling capacity, but that does not mean the size suits every home. A contractor should calculate the home’s heating and cooling load rather than copy the capacity of old equipment. For a straightforward replacement, budgeting about $11,000-$15,000 is a practical starting point.
Assumptions: U.S. residential pricing, standard-access installation, matched equipment, and no major duct replacement.
How Equipment, Labor, and Removal Shape the Quote
Quotes divide the price among the outdoor unit, indoor coil or air handler, installation labor, and any supporting work. The table shows typical ranges for a replacement job; contractor proposals may combine several items into one installed price.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| Condenser and indoor coil | $4,500-$9,500 | Efficiency, brand, refrigerant, and coil compatibility |
| Installation labor | $2,000-$4,500 | Crew hours, access, line-set work, and commissioning |
| Furnace or air handler | $2,000-$6,000 | Heating type, capacity, venting, and blower features |
| Removal and disposal | $250-$800 | Old equipment, refrigerant handling, and disposal rules |
| Electrical, pad, or permit work | $300-$2,000 | Disconnects, concrete pad, inspection, and code updates |
Ask for equipment model numbers and a line-item description so the installed price can be compared fairly.
Which SEER2 Rating and Duct Changes Raise the Price?
Efficiency is a major equipment cost driver. A standard-efficiency 5-ton system often costs less than a variable-speed or higher-SEER2 model; moving to premium equipment may add roughly $1,500-$4,000, depending on the matched indoor and outdoor components. Actual energy savings depend on local electricity rates, operating hours, and system setup.
Duct condition also matters. Sealing and minor repairs may add $300-$1,500, while replacing accessible ductwork can cost about $2,000-$6,000 or more. A system with inadequate return airflow may need added return ducts or grille changes to perform properly.
Capacity should be verified, especially when the old unit is 5 tons. Oversizing can increase cycling and comfort problems, so a load calculation is more useful than assuming the existing size is correct.
Does a Heat Pump Cost More Than AC With a Furnace?
A 5-ton heat pump usually costs about $9,000-$19,000 installed, while central AC paired with a new furnace often totals $10,000-$21,000. The heat pump handles both cooling and heating; the AC-and-furnace option uses separate equipment for each. Cold-climate performance, backup heat, fuel prices, and existing furnace condition affect which quote makes financial sense.
If the furnace is in good condition and compatible with the new coil, replacing only the AC may avoid $2,000-$6,000 in furnace expense. Compatibility and remaining service life should be checked before retaining older equipment. Compare the total matched-system quote, not just the outdoor unit price.
How Many Labor Hours Does a 5-Ton Replacement Take?
A basic changeout often takes a crew of two or three about 8-14 hours. Replacing a furnace at the same time, modifying a line set, or correcting wiring can extend the work to one or two days. Labor charges are commonly reflected as a project price, but a rough planning rate is $75-$150 per technician-hour, varying by market and contractor overhead.
This formula is a rough comparison tool, not a separate bill: equipment handling, testing, warranty administration, and business expenses may be included in the installation charge.
Confirm whether startup testing, refrigerant charging, thermostat setup, and permit coordination are included.
Why 5-Ton HVAC Quotes Differ by Region and Site
Labor and permitting can make installed prices about 10%-20% higher in high-cost metro areas than in lower-cost rural markets. Hot-weather regions may also have busy-season scheduling pressure, while difficult attic or rooftop access can raise labor charges regardless of location.
Other possible extras include a crane or lift at $300-$1,500, a new refrigerant line set at $400-$1,500, and duct replacement at several thousand dollars. Local permits and inspections may total $100-$500, though fees vary widely. Code-required electrical or refrigerant-related updates can add cost.
Request an itemized quote that separates required code work from optional upgrades and site-related extras.
Three Example Quotes for Different 5-Ton Jobs
A simple replacement with standard-efficiency AC, an existing compatible furnace, and no duct repairs might total $9,800: about $5,900 for equipment, $3,300 for labor, and $600 for disposal and permit expenses. A 10-hour crew visit is typical for this scope.
A matched AC-and-furnace replacement with a mid-efficiency condenser, new coil, and minor electrical work could reach $14,600. That estimate might include $9,000 in equipment, $4,600 in labor, and $1,000 in permit, electrical, and removal charges.
A premium heat pump installation with duct repairs and difficult access could total $19,500, including about $12,000 for equipment, $5,000 for labor, and $2,500 for duct and access work. These examples are planning scenarios, not fixed national rates.
How to Lower the Installed Price Without Cutting Capacity
Get at least three written estimates based on the same load calculation, efficiency level, included equipment, and warranty terms. Compare complete installed totals rather than choosing the lowest equipment-only figure. Ask whether existing ducts and the line set can safely remain, but avoid skipping required airflow, electrical, or refrigerant work.
Scheduling outside peak cooling demand may improve contractor availability, although discounts are not guaranteed. Keep the scope focused by declining features that do not match household needs, and check utility incentives for qualifying high-efficiency heat pumps. Preserving usable components and comparing equivalent proposals are usually safer savings measures than buying an undersized system.
