About Our Commercial HVAC Repair & Maintenance

When the HVAC goes down at a restaurant, office, or retail space, every hour costs you customers and comfort. BES keeps Denver Metro businesses running with commercial HVAC repair, scheduled maintenance, and replacement, all through a single point of contact who picks up the phone.

We service rooftop units (RTUs), split and packaged systems, make-up air units, and exhaust for restaurants, retail, offices, warehouses, and multi-tenant buildings. Our preventive maintenance agreements catch failures before they hit: filters, belts, coils, refrigerant, electrical contacts, and economizers checked on a schedule that fits your operation. When a unit is past its life, we right-size and install the replacement with minimal downtime, often after hours or on weekends.

Because BES does both HVAC and electrical, your rooftop power, disconnects, and controls are handled by the same team, with no finger-pointing between trades.

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!

Had BES install a Level 2 EV charger in our garage. They handled the permit, the install was clean and professional, and they even helped us apply for the Colorado rebate. Excellent service!
