FAQ

Rooftop Unit Questions

Common questions about commercial RTU service

Commercial RTUs should be professionally serviced at least twice per year - once before cooling season and once before heating season. High-use units, or units on a dusty roof or near a kitchen exhaust, may need quarterly maintenance. Regular service prevents breakdowns and extends equipment life.

Common RTU cooling failures include low refrigerant from leaks, dirty condenser coils, failed compressors or condenser fan motors, economizer malfunctions, broken belts, and control board or sensor issues. We diagnose the actual cause before replacing parts so the repair fixes the problem.

We work on packaged rooftop units of any size, including gas-fired units, on offices, schools, retail, grocery, restaurants and other commercial buildings across the Treasure Valley.

We answer 24/7 and offer 2-hour emergency response: for emergency calls, we aim to have a technician on-site within 2 hours. Non-emergency RTU calls are scheduled around your business hours. Response times can vary with location, weather and call volume.

Brands we commonly service include AAON, Daikin Applied, McQuay, Carrier, Lennox, Trane, York and Rheem, along with the other packaged units found on commercial roofs in the Treasure Valley.

Commercial rooftop units typically last 15-20 years with proper maintenance. Factors affecting lifespan include maintenance frequency, operating conditions, and installation quality. Units over 15 years old may be worth replacing for better efficiency and reliability.

Consider replacement if your RTU is over 15 years old, still runs on R-22 refrigerant, needs frequent repairs, or its performance has dropped off. We'll give you an honest repair-versus-replace recommendation based on the repair cost and the condition of the unit, and we handle commercial rooftop unit replacement when it's time.

Yes. We can schedule major repairs and replacements for after hours, weekends or school breaks so the work doesn't disrupt classes, tenants, customers or service. After-hours and emergency work is billed at overtime rates.

Yes. Standard maintenance visits include a filter change, coil cleaning, belt inspection and replacement, an electrical check and a refrigerant leak check, plus economizer and gas heat checks on rooftop units. Contract customers get priority dispatch and service records for each unit. Every agreement is priced as a custom contract for your equipment.
