Cost by system scenario

Equipment type, tonnage and whether the ductwork or electrical has to change move HVAC pricing more than brand does. Every row is priced against the Lawrence median.

ScopeWhat it includesTypical installed cost
Straight equipment swapSame tonnage, existing ducts and pad reused$5,600$7,600
Higher-efficiency replacementUpgraded SEER2 tier, same configuration$7,600$10,000
Heat pump conversionElectric heat pump replacing AC plus furnace or strips$8,800$12,000
Replacement with duct repairSealing, resizing or replacing failed duct runs$10,000$13,600
Ductless multi-zoneThree to four indoor heads, new line sets$9,600$13,600
  • Correct sizing comes from a load calculation, not from matching the old unit's tonnage — an oversized system short-cycles and costs more to run.
  • Line-set replacement and electrical disconnect work are common add-ons on a swap that was quoted as straightforward.
  • Refrigerant transition rules mean older-refrigerant equipment is no longer a like-for-like replacement in most markets.

Basis: Each scope is priced as a multiple of the modeled Lawrence median for ac replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Labor in the price

$3,600

45% of the median — the rest is material, disposal and permit.

Because labor is 45% of this job, Lawrence wage levels move the price far more than material prices do. A quote well under this labor figure usually means a smaller crew, a longer schedule, or unlicensed help.

Frequently asked questions

Do I need a permit to replace an AC unit?

Yes. A mechanical permit is required for a residential air conditioner changeout in every Florida jurisdiction, and the work must be inspected. Licensed HVAC contractors pull this permit as part of the job.

What size AC do I need in Florida?

A rough Florida rule of thumb is one ton of cooling per 500-600 square feet of conditioned space, but proper sizing uses a Manual J load calculation that accounts for insulation, window area, orientation and ceiling height. Oversized systems short-cycle and fail to remove humidity.

How long does an AC last in Florida?

Because systems run nearly year-round and coastal salt air accelerates corrosion, Florida air conditioners typically last 10-15 years versus 15-20 in cooler climates.
