A Unico air handler costs about $2,500-$5,500 for the equipment, while a complete high-velocity system installation commonly runs $12,000-$25,000. Final pricing depends on system capacity, the condition of existing ducts, access for small-diameter tubing, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unico air handler equipment | $2,500 | $4,000 | $5,500 | Unit only; capacity and configuration vary |
| Air handler replacement | $4,500 | $6,500 | $9,000 | Existing compatible system and ductwork |
| Complete Unico system | $12,000 | $18,000 | $25,000 | Air handler, cooling equipment, tubing, and installation |
| High-velocity tubing | $8 | $14 | $22 | Per linear foot installed, depending on access |
What a Unico high-velocity installation typically costs
For a typical 1,500-2,000-square-foot home, a complete Unico high-velocity system may cost $12,000-$25,000 installed, with an average near $18,000. This estimate generally assumes one system, standard cooling capacity, accessible attic or basement routes, and no major electrical or structural work. A larger home, multiple zones, or difficult finished-wall access can push the project above the typical range.
Replacing only an air handler on an existing compatible system usually costs $4,500-$9,000 installed. That price is not comparable to a full retrofit, which may require new supply tubing, outlets, returns, and outdoor cooling equipment. Assumptions: U.S. midrange labor rates, standard equipment, normal access, and no major code upgrades. The scope of ductwork is often the biggest difference between an air-handler replacement and a full Unico installation.
Air handler, tubing, and labor in a Unico quote
Contractor quotes should separate the equipment from distribution work and installation labor. Older homes without conventional ductwork may need many small supply runs, making tubing and access work a substantial share of the total. Ask whether the price includes a return-air path, controls, startup, and disposal of removed equipment.
| Quote item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Air handler and controls | $2,500 | $4,000 | $5,500 | Equipment, before installation |
| High-velocity tubing and outlets | $2,000 | $4,500 | $8,000 | Approximately 150-350 linear feet, installed |
| Installation labor | $3,000 | $5,000 | $8,000 | Equipment setup and distribution work |
| Electrical, removal, and miscellaneous | $500 | $1,500 | $3,000 | Basic connections and disposal; upgrades cost extra |
A line-item estimate helps reveal whether a low bid excludes tubing, electrical work, or old-equipment removal.
How capacity, outlet count, and access change the price
System sizing is based on a heating and cooling load calculation, not square footage alone. A home needing roughly 2-3 tons of cooling may fall near the middle of the equipment range, while a larger or higher-load home may need more capacity or separate zones. Oversizing can raise equipment cost and may affect comfort, so the contractor should explain the load calculation and selected model.
Outlet count and route length also matter. A design with 20-30 outlets and 200-300 feet of tubing costs less than one requiring extensive branching or long runs around finished rooms. Tight attic access, plaster walls, multiple floors, and concealed framing can add labor. Confirm the proposed outlet count, tubing footage, and access assumptions before comparing bids.
How many labor hours does a Unico retrofit take?
A straightforward air-handler swap may take a two-person crew about 8-16 hours if the compatible distribution system remains in place. A full retrofit in an existing home commonly takes a crew of two or three about 3-7 working days, depending on the number of outlets, finish repairs, and equipment access. Typical HVAC labor rates run about $75-$150 per technician-hour, although contractors often price the project as a package.
Work involving finished ceilings, long attic runs, or multiple zones may require additional carpentry or electrical labor. Clarify whether patching and painting are included; they are often handled separately. Installation duration is a useful quote check, but the crew’s stated hours should match the planned tubing and outlet scope.
How Unico installation prices vary by U.S. region
Labor and contractor availability can shift the installed price. Dense urban markets and high-cost coastal areas may run 15%-30% above a typical national estimate, while some rural markets may be 5%-15% lower. Remote locations can still cost more if equipment delivery, travel, or limited installer availability adds charges.
Older housing stock can also affect regional quotes: homes with plaster, limited attic space, or historic-preservation restrictions may need more careful routing. These are project conditions rather than fixed regional premiums. Compare local bids for the same capacity, outlet count, tubing footage, and included finish work.
When repair costs less than replacing the Unico air handler
A diagnostic visit commonly costs $100-$250, and repairs such as a capacitor, control, or fan-related part may total roughly $200-$900, depending on the fault and access. A motor or major control-board replacement can reach $500-$1,500. Parts availability and the age of the equipment influence whether repair makes sense.
If the unit is failing repeatedly, has a major component failure, or is near the end of its expected service life, compare repair costs with a $4,500-$9,000 compatible replacement. A full system replacement is a different scope and may be necessary if the tubing or cooling equipment is also unsuitable. Request a written diagnosis and a repair-versus-replacement quote before approving a large repair.
Extra charges for old ducts, electrical work, and finish repairs
Unico’s small-diameter distribution can be useful where conventional ducts are difficult to fit, but routing still takes planning. Removing an old system may add $300-$1,200, depending on disposal and access. New circuits, panel work, condensate-drain changes, or repairs to walls and ceilings may add several hundred dollars to several thousand.
Permits and inspections vary by locality; allow roughly $100-$600 for common mechanical permits, with higher fees possible for larger projects or multiple permits. A quote should state whether these charges are included. Get exclusions in writing, especially for electrical upgrades, permitting, asbestos concerns, and finish repairs.
Where homeowners can trim a Unico project budget
Keeping usable components can reduce the bill, but only when the existing air handler, cooling equipment, controls, and tubing are compatible and in sound condition. Ask the contractor to price a repair or partial replacement separately from a full system. Avoid paying for extra zones or outlets unless the design calculation and room layout support them.
Prepare clear access to the air handler and planned routes before installation, and compare at least three itemized quotes with matching equipment and scope. Scheduling outside peak cooling-season demand may improve contractor availability, though savings are not guaranteed. Scope control and like-for-like quote comparison are more dependable savings strategies than choosing equipment by price alone.
