Rooftop Unit Service in Greenwood Village & Denver, CO
Commercial rooftop unit installation, replacement, and preventive maintenance.
About Our Rooftop Units (RTU)
Most small and mid-size commercial buildings in the Denver Metro are heated and cooled by packaged rooftop units. BES installs, replaces, repairs and maintains rooftop units for offices, retail centers, restaurants, warehouses and multi-tenant properties, and we also handle the electrical side of the job, so one contractor covers the unit, the disconnect and the power feed.
What we do on the roof
New installations and like-for-like replacements, including curb adapters, crane coordination and the electrical and gas connections. Repairs on compressors, condenser and evaporator fans, belts and motors, contactors, controls and refrigerant leaks. Economizer testing and repair. Preventive maintenance visits on a schedule that fits your building.
Repair or replace?
We tell you what is wrong, what it costs to fix and where the unit is in its life, and you decide. A repeat compressor failure or a unit well past the end of its service life often points toward replacement; a failed capacitor or contactor does not. We give you the repair quote and a replacement option side by side when both make sense.
Maintenance that prevents the emergency call
Dust, pollen and the swing between hot summers and cold winters are hard on Colorado rooftop equipment. Regular filter changes, coil cleaning, belt and electrical checks and drain line clearing catch most failures before they shut your space down on the hottest day of the year. Maintenance agreements can cover one building or a whole portfolio, with one invoice and one point of contact.

Rooftop Units (RTU) 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.
A common rule of thumb: if the unit is well into the second half of its service life and the repair quote is a large share of replacement cost, replacement usually wins. Newer units are more efficient, and some may qualify for utility rebates; ask us and we will look at what applies to your equipment. We give you the repair quote and the replacement option side by side.
