Why Rooftop Units Need Attention

What happens if you wait:
- Weather and debris wear the unit down faster.
- One RTU fault can shut down an entire zone.
- Neglected units lose efficiency and raise bills.
- Small refrigerant leaks grow into compressor failures.

Rooftop Unit Service FAQs
What is a rooftop unit (RTU)?
An RTU is a self-contained package HVAC unit mounted on a commercial roof. It both heats and cools and pushes conditioned air through the building's ducts. Most offices, shops, and restaurants rely on one or more RTUs.
How often should rooftop units be serviced?
At least twice a year — before cooling season and before heating season — because RTUs run hard and sit exposed to the weather. Regular service catches worn belts, dirty coils, and leaks before they cause a shutdown.
Can you repair any brand of RTU?
Yes. We service common commercial rooftop package units of all major brands. Call (949) 593-2781 with the unit details and symptoms and we'll come prepared.
Do you offer preventive RTU contracts?
Yes. A maintenance contract schedules regular RTU tune-ups so your units stay reliable and efficient. It's the best way to avoid surprise commercial breakdowns. Ask about our maintenance contracts.
