RTU Installation
New rooftop units for offices, retail, restaurants, warehouses. Includes crane coordination, curb adapters, and electrical/gas tie-in.
RTU Replacement
Like-for-like swaps or upgrades to higher-efficiency units. We handle Xcel rebate paperwork on qualifying high-efficiency RTUs.
Preventive Maintenance
Quarterly or biannual PM contracts: belt and pulley check, coil cleaning, refrigerant pressures, electrical contact torque, drain line clearing.
Emergency RTU Repair
Roof access, parts, and recovery equipment all on the truck. Most repairs completed same-day so your business stays open.
Economizer Service
Many RTUs run with seized or stuck economizer dampers, wasting 15–30% of conditioning cost. We test, repair, and recalibrate.

“BES came out same-day when our AC went out during a heat wave. The tech was professional, explained everything, and had us cool again in under 2 hours. Highly recommend!”

Rooftop Units FAQs
A well-maintained packaged rooftop unit lasts 15–20 years; a neglected one often fails in 8–12. The biggest factors in Colorado are filter changes, coil cleaning (dust and pollen accumulate fast at altitude), and catching refrigerant leaks before the compressor burns out.
