Frequently Asked Questions — Rooftop Unit (RTU) Service
What qualifications should a commercial rooftop unit (rtu) service contractor have?
Commercial HVAC contractors should hold a state contractor's license, carry general liability insurance ($1M+ per occurrence), and employ NATE-certified technicians. For refrigerant work, EPA Section 608 certification is federally required. For specialized equipment like chillers or BAS systems, look for manufacturer-specific certifications.
How do I get accurate pricing for rooftop unit (rtu) service?
Request itemized written quotes from at least three contractors. Be specific about your system type, building square footage, and the scope of work. Avoid contractors who quote without a site visit for anything beyond simple repairs. Compare warranties on both labor and parts, not just the bottom-line price.
How long does rooftop unit (rtu) service typically take?
The timeline depends heavily on system complexity, parts availability, and permit requirements. Simple repairs often complete same-day. Equipment replacements typically take 1–3 days. Complex installations or large-scale projects may require weeks of planning, coordination, and phased execution to avoid disrupting building occupants.
Can I schedule rooftop unit (rtu) service outside business hours?
Many commercial HVAC contractors offer after-hours, weekend, and holiday scheduling — especially for facilities that can't tolerate business interruption. Plan for premium pricing during off-hours. For preventive work, scheduling during low-occupancy periods is often easier on building operations.
