Save $4,500 – $18,000 on RTUs ⏱ Itemized Mechanical Bids

Compare Commercial HVAC Replacement & Service Quotes

Don't pay inflated commercial mechanical markups. Compare 3–4 engineered proposals on packaged rooftop units (RTU), chillers, VRF multi-splits, and scheduled commercial preventive maintenance contracts.

Why Comparison Shopping Saves Money & Time:

Commercial heating, ventilation, and air conditioning systems require precise psychrometric engineering, crane rigging logistics, and municipal commercial permits. Shopping competing commercial mechanical contractors prevents inflated equipment margins and locks in comprehensive labor and compressor warranties.

Why Commercial Property Owners & Business Executives Must Compare Commercial HVAC Bids

Commercial HVAC systems represent one of the largest capital expenditures and ongoing operational costs for office parks, retail plazas, manufacturing plants, and hospitality venues. Unlike residential heating and cooling, commercial mechanical systems must manage heavy ventilation ventilation air requirements (ASHRAE Standard 62.1), continuous thermal loads from computers and lighting, and multi-zone occupancy shifts. When an aging rooftop unit fails, rushing into a single contractor's quote often results in paying a 30% to 50% premium for rush delivery and crane rental. By soliciting competing commercial HVAC quotes through ClickQuoteSave, property managers gain transparency into wholesale equipment pricing, labor rates, crane rigging fees, and local utility commercial rebates that can offset thousands of dollars in capital outlay.

  • Always demand an Integrated Energy Efficiency Ratio (IEER) rating comparison—high-IEER multi-stage inverter RTUs run at part-load 85% of the time, slashing annual electricity bills by up to 35%.
  • Require contractors to include custom transition curb adapters in the bid to avoid expensive roof cutting and structural re-flashing when changing equipment brands.
  • Review the scope of the included crane rigging and municipal street closure permitting—these ancillary line items can swing total project costs by $2,000 to $5,000.

Commercial Rooftop Units (RTUs) vs. Split Systems vs. VRF Technology

Selecting the right commercial HVAC architecture depends on your facility's physical layout. Self-contained Packaged Rooftop Units (RTUs) are the workhorses of single-story retail, big-box stores, and warehouses due to easy rooftop access and zero indoor footprint. Multi-story office buildings and hotels increasingly prefer Variable Refrigerant Flow (VRF) systems for simultaneous heating and cooling in separate zones, while large institutional complexes rely on central chilled water loops.

Frequently Asked Questions About Commercial HVAC & Rooftop Units

How much does a commercial rooftop HVAC unit (RTU) replacement cost?

Turnkey commercial RTU replacement typically ranges from $7,500 to $16,000 for a 3-to-5 ton unit, $14,000 to $28,000 for a 10-to-15 ton unit, and $35,000 to $75,000+ for large 25-to-50 ton packaged units. Pricing includes the commercial unit, crane rigging, curb adapter, economizer, thermostat integration, and labor.

What is a curb adapter and why is it needed during RTU replacement?

A curb adapter is an engineered sheet metal transition collar installed between the existing roof curb and the new rooftop unit. It reroutes the supply and return air duct drops to match the new unit's footprint without requiring expensive roof structural modifications or ductwork redesigns.

How can commercial property owners benefit from Section 179 and utility rebates?

Under IRS Section 179 tax deductions, qualifying businesses can immediately expense 100% of the cost of new commercial HVAC equipment placed in service during the tax year. Additionally, local electric utilities frequently offer commercial energy rebates ranging from $50 to $150 per ton for installing high-IEER multi-stage systems.

What should be included in a commercial HVAC preventive maintenance contract?

A comprehensive commercial PM agreement includes quarterly coil cleaning, belt inspections, refrigerant pressure checks, electrical contactor testing, economizer calibration, filter changes, and priority emergency dispatch with discounted diagnostic rates.
