Unico high-velocity air conditioning typically costs $12,000-$25,000 installed, with complex whole-home retrofits reaching $30,000 or more. The final price depends on home size, existing duct access, equipment capacity, electrical work, and local labor rates.

| Installed Unico system | $12,000 | $18,000 | $30,000+ | Whole-home retrofit; complex access can raise the total |
| Equipment package | $5,000 | $8,000 | $12,000 | Air handler, outdoor unit, and controls |
| Small-duct installation | $4,000 | $7,000 | $12,000 | Plenum, branch tubing, outlets, and installation labor |
| Typical project rate | $8 | $12 | $20+ | Approximate installed cost per conditioned square foot |
What does a Unico high-velocity installation cost?
Most homeowners pay about $12,000-$25,000 for a complete Unico system in an existing house. A straightforward project in a smaller home may start near $10,000-$12,000, while a large, difficult retrofit can exceed $30,000. These figures generally include the Unico air handler, outdoor cooling equipment, small-duct distribution, outlets, controls, and contractor labor.
A practical planning figure is $15-$20 per conditioned square foot for a full retrofit. A 1,500-square-foot home might therefore fall around $22,500-$30,000 if the work is extensive, though lower-cost layouts or partial-system scopes can bring the total down. Per-square-foot figures are rough comparisons, not substitutes for a load calculation and site quote.
Assumptions: U.S. pricing for a standard residential retrofit, ordinary access, and midrange equipment; regional labor rates and project scope vary.
How air-handler, small-duct, and labor charges shape a Unico quote
The installed total combines equipment, distribution work, and the labor needed to route small ducts through an existing home. The following ranges are approximate portions of a typical project, not guaranteed line-item prices. Contractor overhead and the way equipment is bundled can shift the breakdown.
| Quote component | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Unico air handler and controls | $3,000-$6,500 | Per system | Indoor unit, control components, and plenum |
| Outdoor cooling equipment | $2,500-$5,500 | Per system | Condenser or compatible outdoor unit |
| Small-duct materials and outlets | $1,500-$4,000 | $10-$25 per outlet, plus trunk materials | Flexible branch tubing, fittings, and room outlets |
| Installation labor | $4,000-$9,000 | About $75-$150 per worker-hour | Equipment setting, routing, connections, and startup |
| Electrical, permits, and disposal | $500-$2,500 | Per project | Possible circuit work, permit fees, and removal |
Labor can account for a large share of the quote because tubing must reach multiple rooms with minimal disruption. Ask whether the proposal includes startup testing, thermostat work, condensate drainage, and cleanup.
Which home size, duct route, and capacity raise retrofit prices?
Capacity and layout matter more than a simple square-foot rule. A contractor should perform a heating and cooling load calculation; a system that is too small may struggle on hot days, while oversizing can add equipment expense and affect comfort. Homes around 1,000-1,500 square feet may need less capacity and fewer outlets than houses above 2,500 square feet, but insulation, windows, ceiling height, and climate change the calculation.
Long, obstructed routes and a high outlet count are major labor drivers. A one-story home with accessible attic or basement paths is generally less demanding than a multistory home with finished walls and few chases. Adding more than roughly 10-15 outlets, crossing fire blocks, or working around plaster can increase tubing, patching, and labor costs.
Electrical capacity is another threshold to check. If the existing panel cannot support the required circuit, an electrician may recommend a new circuit or panel work, potentially adding $500-$3,000 or more depending on the service and local code. A separate zone or second air handler can also change the project from a single-system installation to a larger equipment and controls package.
How to lower a Unico installation quote without cutting comfort
Compare bids for the same capacity, outlet count, control package, and included repairs. A low total may exclude electrical work, wall patching, permit fees, or removal of old equipment. Request an itemized scope and confirm how the contractor calculated capacity rather than accepting a size based only on the previous system.
Keeping the project to necessary rooms and avoiding optional upgrades can reduce the initial bill. If some areas already have dependable heating or cooling, ask whether a carefully designed partial installation is feasible. Choosing standard controls instead of premium zoning or smart-home add-ons may also save money when those features are not needed.
Scheduling well before peak summer demand can make it easier to compare contractor availability, although savings are not guaranteed. Homeowners can reduce paid prep time by clearing access to the attic, basement, and equipment location. Do not take on refrigerant handling, electrical connections, or system commissioning as DIY work.
How many days does a Unico retrofit take, and what affects labor?
A typical retrofit takes about 2-5 working days, often with a crew of 2-4 installers. An uncomplicated home with clear routing may be completed in 2-3 days; a larger multistory house, difficult access, or substantial finish repair can extend the schedule to a week or more. Installation time is not the same as total calendar time, since equipment ordering and permit approval may add delays.
Labor estimates should name the crew size, expected workdays, and finish work included. Ask whether the crew will open and patch ceilings or walls, and whether painting is excluded. If an electrician or separate drywall contractor is needed, their hours and charges may appear outside the HVAC bid.
How Unico compares with conventional central AC in an older home
Conventional central AC may cost less when usable ductwork already exists, with many replacements landing around $6,000-$12,000 depending on capacity and equipment. Adding new conventional ducts to a house without them can raise the total to roughly $12,000-$25,000 or more, especially when finished rooms must be opened. A Unico system can be competitive when its small tubing avoids extensive demolition, but it is not automatically cheaper.
Compare the cost of the complete installed system, not just the air handler price. Include duct construction, ceiling or wall repairs, efficiency, controls, and any heating equipment in both estimates. Ask each contractor to identify the rooms served and what is excluded so the alternatives are comparable.
What removal, electrical work, and permits can add to the bill
Removing old equipment and disposing of it may add around $200-$800, while a new electrical circuit can add roughly $300-$1,500. Panel replacement, difficult condensate routing, or extensive patching can cost more. Permit fees often run about $50-$500, but local rules and inspection requirements differ; some jurisdictions require additional work to meet current electrical or mechanical codes.
Confirm these potential extras before accepting a fixed-price proposal. The quote should clarify who obtains permits, whether inspections are included, and how concealed conditions are handled. If old equipment contains refrigerant, removal should be performed by qualified personnel following applicable requirements.
Do regional labor rates and summer scheduling change Unico prices?
Prices tend to be higher in costly metropolitan markets and areas with limited HVAC contractor availability. A reasonable comparison is roughly 10%-25% above a national-style estimate in some high-cost urban markets, while rural areas may be 5%-15% lower when travel and equipment access are uncomplicated. These are broad planning differences, not fixed regional tariffs.
Summer urgency can narrow scheduling choices and may increase labor charges by about 5%-15% where crews are heavily booked. Weather, local demand, and contractor workload affect the timing more than a guaranteed seasonal discount. Getting multiple written bids during a flexible period helps show whether a premium reflects scope, local rates, or rush scheduling.
