How much does it cost to replace a rooftop HVAC unit?

Replacing a packaged rooftop unit costs about $8,000-$30,000 in 2026, or $2,800-$3,500 per ton installed for smaller units and $1,800-$2,500 per ton for larger commercial units. A typical 5-ton clubhouse RTU lands around $14,000-$17,500 installed. Add $3,000-$8,000 for crane, curb adapter, and electrical work if those aren't in the base quote.

What is the life expectancy of a rooftop package unit?

Commercial useful-life charts give rooftop package units 15-25 years, with ASHRAE-derived tables using 15 years as the median. Units in hot climates that run near-continuously trend toward 15 years, while units with quarterly filter changes and annual coil cleaning routinely reach 20-25. Most reserve studies schedule replacement at 15-20 years.

Should an HOA repair or replace a 15-year-old rooftop unit?

At 15+ years, put replacement on the reserve schedule: a compressor failure alone can cost $3,000-$7,000 against a $8,000-$30,000 full replacement, and older units use phased-out refrigerants that make repairs increasingly expensive. New units also cut energy costs 20-40% versus 15-year-old equipment. Repair only when the fix is small relative to remaining useful life.

HVAC Rooftop Package Unit: Useful Life & Replacement Cost for HOAs

Packaged rooftop HVAC units (RTUs) typically last 15-25 years and cost about $8,000-$30,000 per unit to replace, which works out to roughly $1,800-$3,500 per ton installed in 2026. A 3-5 ton clubhouse unit sits at the low end; 10-ton-plus commercial units, high-efficiency equipment, and difficult crane access push projects toward and past $30,000. ASHRAE-based tables use 15 years as the median service life, with well-maintained units reaching 20-25.

Reserve budgeting

Inventory every association-owned RTU with its tonnage and install date — clubhouses, fitness rooms, and office spaces often each have their own unit on different clocks. Budget beyond the equipment quote: crane mobilization, curb adapters, and electrical upgrades are the most commonly missed items and collectively add $3,000-$8,000 per project, and refrigerant phase-outs can force early replacement of otherwise serviceable units.

Extending its life

Replace filters quarterly, wash condenser and evaporator coils annually, and keep a semiannual preventive-maintenance contract that checks refrigerant charge, belts, and electrical connections. Coil cleaning and consistent filter changes are the difference between a 15-year and a 25-year unit, and coastal units benefit from factory coil coatings.

Regional variation

Hot-climate regions (Southwest, Gulf) shorten compressor life through longer run hours, coastal air corrodes coils and cabinets, and crane access matters more to price than geography.
