Buyers replacing or installing a 5 ton RTU typically pay between $7,500 and $18,000 total depending on unit efficiency, rooftop access, and whether gas heat is included. This 5 ton RTU cost article breaks down equipment, labor, common add-ons, and regional variations to help estimate realistic budgets.

Item	Low	Average	High	Notes
Installed 5‑ton RTU (complete)	$7,500	$12,500	$18,000	Assumptions: typical 2,500–3,000 sq ft single-story commercial roof, standard duct tie-in.
Equipment Only (5‑ton)	$4,000	$6,500	$9,000	Varies with SEER, heat type, economizer.
Labor & Rigging	$1,500	$3,200	$6,000	Includes crane, crew, curb work.
Permits & Disposal	$150	$500	$1,200	Local code and disposal fees vary.

Installed Price Ranges For A 5‑Ton Rooftop Unit

Typical installed totals range from $7,500 on the low end to $18,000 for high-end installs with gas heat and high-efficiency controls.

Equipment-only 5‑ton RTUs generally cost $4,000-$9,000 depending on SEER/EER and whether packaged gas heat is included. A full install adds labor, crane/rigging, curb work, and controls to reach the installed ranges above. Assumptions: Midwest labor rates, standard curb, normal rooftop access.

Breakdown Of Major Cost Components In A Quote

A buyer should expect the quote to separate equipment, labor/rigging, permits, and disposal as distinct line items.

Materials	Labor	Equipment (Rigging)	Permits	Delivery/Disposal
$4,000-$9,000 (RTU unit, controls)	$1,500-$4,500 (installation labor)	$800-$3,500 (crane, rigging)	$100-$700	$150-$1,000

Typical labor rates: $75-$125 per hour; typical crew 2–4 techs; 8–20 hours depending on complexity.

How SEER Rating, Heat Type, And Controls Affect Price

Upgrading efficiency or adding gas/electric heat can increase equipment cost by 20%-60%.

Examples: a basic 13–14 SEER 5‑ton RTU: $4,000-$6,000; a 16–18 SEER with variable-speed blower and economizer: $7,000-$9,000. Adding packaged gas heat or two-stage compressors typically adds $1,200-$3,000. Controls and internet-enabled thermostats: $300-$1,200.

Site Conditions That Drive Significant Price Changes

Rooftop access, curb condition, and roof height frequently change rigging and labor costs more than the unit price.

Numeric thresholds to watch: roof height over 30 ft often adds $800-$2,500 for larger crane or permit requirements; curb replacement >2 ft of modification adds $600-$2,000; duct runs over 30 linear feet needing fabrication add $500-$4,000. Poor access or tight city streets can raise crane and traffic-control fees.

Practical Ways To Reduce The 5‑Ton RTU Price

Controlling scope and scheduling off-season installs are the fastest ways to reduce total installed cost.

Strategies: keep existing curb if structurally sound, preserve duct connections to avoid extensive fabrications, schedule outside peak summer months to reduce contractor urgency fees, and accept a mid-range SEER (14–16) instead of top-tier units. Collect 3 competitive quotes and request line-item pricing to compare specific markups.

Typical Timelines, Crew Size, And Labor Estimates

Most 5‑ton RTU replacements take 1–2 days on site with a 2–4 person crew when access is normal.

Estimate: 10–12 hours for skilled crew plus 2–6 hours of crane/rigging time. Labor formulas: 10–20 hours × $75-$125/hr yields $750-$2,500 in direct labor; add crane and general conditions to reach full labor/rigging line item of $1,500-$4,500.

Three Real-World Quote Examples For Budgeting

Concrete examples help compare how specs and site change totals.

Scenario	Specs	Labor Hours	Per‑Unit Rates	Total
Economy Replace	5‑ton, 14 SEER, electric heat, existing curb usable	10 hrs	$1,200/ton installed estimate	$7,500
Mid-Range Upgrade	5‑ton, 16 SEER, economizer, new curb	16 hrs	$2,500/ton installed	$12,500
High-End Packaged	5‑ton, 18 SEER, gas heat, high roof, crane lift	24 hrs	$3,600/ton installed	$18,000

Use these examples to match the building’s specs and expected access before requesting quotes.
