Commercial HVAC Installation From $8,000 — Mabank & DFW

Commercial HVAC installation is where most contractors pad quotes by 30-50% — assuming you'll get fewer competing bids than a residential customer. We don't do that. We quote commercial work the same way we quote residential: honest scope, real labor estimate, equipment at fair markup, no padding for 'commercial premium.' Commercial rooftop unit installation starts at $8,000 for a basic 3-ton RTU, ranging up to $60,000+ for large multi-unit build-outs. Whether you're planning a build-out, an emergency rooftop replacement, or a phased system upgrade across multiple properties, we'll quote it straight.

Rooftop Unit Replacement — What to Expect

Most rooftop unit replacements follow the same timeline:

• Day 0: Free commercial estimate — rooftop inspection, load calculation, ductwork inspection, electrical inspection, discussion of downtime constraints, written quote within 3-5 business days
• Week 1-2: Quote acceptance and equipment ordering (most standard RTUs available in 1-2 weeks; larger or specialty units 3-6 weeks)
• Week 2-4: Permit pulled (we handle the paperwork; some jurisdictions take 5-10 business days)
• Install day 1 morning: crane setup (if needed), old RTU disconnected, old unit lifted off roof
• Install day 1 mid: new curb adapter installed (if needed), new RTU set, electrical and gas connections
• Install day 1 end: refrigerant charge, thermostat integration, initial startup and commissioning
• Install day 2 (larger units): full commissioning — static pressure verification, temperature split, combustion analysis on gas heating section, integration with building automation if applicable
• Follow-up: permit inspection scheduling, warranty registration, documentation package delivery

We coordinate crane access (when needed), pull permits, and schedule replacement during your slow hours when possible. Detailed written quote provided before any work begins — including scope, equipment specs, labor estimate, timeline, and disposal.

Portfolio and Multi-Property Commercial Installs

Property managers and multi-location business owners often benefit from planned portfolio upgrades:

• Phased replacement scheduling — assess all units across all properties, prioritize by failure risk and energy inefficiency, spread replacement cost across 2-4 year budget
• Bulk equipment pricing — ordering 6+ RTUs in a coordinated schedule unlocks manufacturer volume pricing (usually 8-15% below single-unit pricing)
• Consolidated documentation — single COI covering all properties, unified warranty tracking, standardized service reports
• Assigned project manager — one point of contact across all locations and installs
• Coordinated with lease terms — align replacement schedule with tenant renewals, lease negotiations, or CapEx budget cycles

Multi-property commercial installation quotes available — we scope portfolio-wide and give you a phased plan with real timelines and budget.

Build-Out HVAC for Tenant Improvement Projects

New tenant build-outs require HVAC design coordinated with the general contractor, electrician, and often the fire marshal. Our commercial build-out process:

• Manual N commercial load calculation — not residential Manual J; accounts for occupancy load, equipment load, ventilation code requirements (ASHRAE 62.1), and process cooling needs
• Duct design — Manual D or engineering-firm ductwork design for adequate airflow to every space
• Controls integration — thermostat locations, occupancy sensors, building automation (BAS) integration where applicable
• Coordination with GC schedule — we sequence our work around framing, electrical rough-in, drywall, ceiling grid
• Health department pre-approval — for restaurants and food service, we coordinate on kitchen ventilation, walk-in cooler HVAC, dining area comfort cooling
• Fire marshal compliance — duct penetrations through rated walls, fire damper installation, smoke damper integration
• Final commissioning + documentation package — TAB (Test, Adjust, Balance) report, commissioning documents, warranty registration for landlord and tenant records
