How Much Does Air Handler Replacement Cost?
Air handler replacement typically costs about $3,300 at the Standard level for a 3-ton air handler with a matched coil in a 2,000 to 2,500 square foot home, and about $2,100 to $5,500 across the Budget to Premium range. Heat strips, a heat pump model and a variable-speed blower cost more.
This calculator uses the following planning figures for a 3-ton system, a standard single-speed blower, a flushed existing line set, existing duct connections, an existing electrical connection, a basement or utility-room install, a gravity drain, removal of the old unit, a permit allowance and an average labor market:
| Air handler | Budget | Standard | Premium |
|---|---|---|---|
| Air handler with coil | $2,065 | $3,330 | $5,505 |
| Air handler with electric heat (10 kW) | $2,315 | $3,735 | $6,160 |
| Heat pump air handler | $2,470 | $4,005 | $6,620 |
Change any input and the numbers update, because the calculator prices the air handler, coil, line set, electrical connection, labor, removal and permit separately.

What Affects Air Handler Replacement Costs?
Type of air handler
An air handler is the indoor unit of a split system without a gas furnace. It holds the blower, the evaporator coil and sometimes electric heat strips. A plain air handler suits an AC-only system. One with heat strips gives backup heat. A heat pump air handler is matched to a heat pump and adds a metering device and defrost controls.
System size
The calculator maps your home size to about 1.5 to 5 tons. At the Standard level, a 1.5-ton unit costs about $2,845, a 2-ton unit about $3,005, a 3-ton unit about $3,330, a 4-ton unit about $3,655 and a 5-ton unit about $3,980. The new unit must match the outdoor unit and the airflow of your ducts.
Blower type
A single-speed blower is the default. A variable-speed ECM blower raises the Standard estimate to about $3,820. A communicating system raises it to about $4,470. Variable-speed models run longer at lower speeds, which is quieter and gives a steadier temperature.
Heat strips
Heat strips give backup heat for the coldest days. At the Standard level, a 5 kW strip gives about $3,615, a 10 kW strip about $3,735 and a 15 kW strip about $3,880 for an air handler with electric heat. A larger strip can need a larger electrical circuit.
Line set
The calculator reuses and flushes the existing line set by default, which works only when the lines are clean and the right size. A new line set raises the Standard estimate to about $3,795.
Duct connections
If the new cabinet is the same size as the old one, the plenums can be reused. A different size needs new sheet metal. A new supply plenum and transitions raise the Standard estimate to about $3,995, and a new plenum with a return drop raises it to about $4,430.
Electrical connection
The default assumes the existing breaker and wiring are fine. A new disconnect and whip raises the Standard estimate to about $3,545, and a new circuit and breaker raises it to about $4,175. A new circuit is common when the new heat strips are larger than the old ones.
Install location and drain
A basement or utility room is the easy case. A closet or crawl space takes more time, and an attic is the hardest. An attic install raises the Standard estimate to about $3,565. A condensate pump, needed when gravity will not work, raises it to about $3,575.
Thermostat and options
A smart thermostat raises the Standard estimate to about $3,705. Options include a media filter cabinet, a UV light or air purifier, a surge protector, a secondary drain pan with a float switch and sealing the duct connections with mastic. A media filter cabinet raises the Standard estimate to about $3,990. Options appear only when they apply.
Removal and disposal
The old air handler must be removed, and its refrigerant has to be recovered by a certified technician. The calculator includes removal, refrigerant recovery and disposal by default. Unchecking it lowers the Standard estimate from about $3,330 to about $3,075.
Permits
Many cities require a permit and an inspection for air handler replacement. The calculator includes a permit allowance of about $200 at the Standard level by default. If you remove it, the Standard estimate falls to about $3,130. The allowance is a planning placeholder, not the municipal fee.
Urgency
Urgent and after-hours calls carry a premium. The calculator adds 15% to labor for work within about 48 hours and 40% for emergencies. An emergency replacement raises the Standard estimate from about $3,330 to about $3,695.
Budget vs Standard vs Premium Air Handler Replacement
The three project levels reflect real differences, not a simple multiplier:
Budget: a basic air handler, a leaner labor rate and fewer labor hours.
Standard: a mid-grade air handler, quality line-set and electrical parts and a licensed installer at typical rates.
Premium: a premium air handler, higher-grade parts, more thorough commissioning and premium service rates.
Use Standard as your main planning number, and the Budget-to-Premium range to see how much your choices can swing the result.
Repair vs Replace
Replacement can make sense when the blower motor has failed and the unit is old, the coil is leaking, the cabinet is rusted or the unit uses an older refrigerant. If only the blower motor or a control part has failed, a repair costs far less. Use the AC repair calculator to compare, and the evaporator coil calculator if only the coil has failed. Note: the evaporator coil calculator (079) was not linked because its address was not verified as live.
Regional Pricing Differences
HVAC labor rates and permit practices vary across the country. Rather than guess from your ZIP code, the calculator lets you choose a labor market, from lower-cost areas to the highest-cost metro areas, and applies it to labor and removal. A highest-cost market raises the Standard estimate from about $3,330 to about $3,765. Equipment and materials are not adjusted.
DIY vs Hiring a Licensed HVAC Contractor
Replacing an air handler is not a DIY project. It involves recovering and handling refrigerant, which requires certification, brazing the lines, evacuating and charging the system, wiring the unit and checking airflow. Most areas require a licensed contractor and a permit.
Questions to Ask HVAC Contractors
- Is the new air handler matched to my outdoor unit, and what are the model numbers?
- Does the price include the coil, or is it extra?
- Is the line set reused or new, and why?
- Will you change the plenums or the return, and is that in the price?
- Does the quote include removal, refrigerant recovery, the permit and a secondary drain pan?
- Will you measure the airflow and the refrigerant charge after the install?
How to Avoid Unexpected Air Handler Costs
- Ask for matched model numbers for the indoor and outdoor units.
- Check the duct connections. A different size cabinet adds sheet metal work.
- Ask for a written scope that lists the equipment, line set, electrical work, removal and permit.
- Check rebates before you sign. Programs and eligible models change.
- Do not wait for a heat wave or a cold snap. Emergency calls cost more.
