Commercial HVAC Services
Commercial HVAC in Colorado
Offices, shops, and rentals need steady heat and cooling too. We repair and maintain rooftop units, split systems, and ductwork for Colorado businesses.
A business loses more than comfort when its HVAC fails. A shop with no heat sends customers back out the door. An office with no cooling loses a workday. A rental with a dead furnace draws calls from every tenant. Commercial systems run longer hours, serve more people, and carry bigger loads than home systems, so they need service planned around the business, not around the house.
For the full picture of how we serve properties across the state, see the homepage. This page covers commercial work only. For homes, see the service page for your system, such as furnace repair or AC repair.
What Commercial HVAC Covers
- Rooftop units. Package units and split systems that serve offices, shops, and restaurants from the roof.
- Split systems. Indoor and outdoor units that serve suites, additions, and small commercial spaces.
- Ductwork. Runs that carry air to each room, office, or tenant space.
- Zoned controls. Thermostats and zone dampers that let each area run its own setting.
- Ventilation. Fresh-air intake and exhaust for kitchens, restrooms, and meeting rooms.
- Planned maintenance. Seasonal checks across every unit in the building.
Package Unit Repair
A package unit holds the compressor, coils, fan, and controls in one rooftop cabinet. When it fails, the whole space it serves loses heating or cooling at once. We diagnose the cabinet, find the failed part, and explain it before any work starts. Common faults include failed capacitors and contactors, worn fan motors, refrigerant leaks, and clogged coils. We also check the curb, the duct connections, and the drain, since roof water and debris cause their share of trouble.
PTAC Units in Hotels and Motels
Hotels and motels often heat and cool each room with a PTAC unit set through the wall under the window. We service PTAC units for hotel and motel properties: cleaning coils and filters, clearing drains, fixing fan and control trouble, and replacing units that no longer hold temperature. Tell us how many rooms the property runs when you call, so we can plan the visit around occupancy and housekeeping.
When Commercial Service Fits, and When It Does Not
Commercial service fits any business property with HVAC it depends on: offices, shops, restaurants, clinics, rentals, and hotels. It fits a building with many units, a building with roof access needs, and a business that needs work planned around open hours.
Commercial service does not change the basics. A rooftop unit and a home unit fail for the same reasons, and they get the same careful diagnosis. The difference is scale and scheduling: more units, more zones, and work planned so the business keeps running. A home system belongs on the residential service page for that system, such as furnace repair or heat pump repair.
Try This Before You Call
Before you call about a commercial unit, these checks help us find the trouble faster. Note what you find.
- Controls: confirm the schedule and setpoints. A building in unoccupied mode will not heat or cool on schedule.
- Breakers: check the panel and the rooftop disconnect for the affected unit.
- Filters: clogged filters on rooftop units cut airflow across the whole floor.
- Roof access: make sure the path to the units is clear and the area around each unit is clear of debris.
- Affected zones: note which zones are warm or cold. One zone points to a zone control; the whole building points to the main unit.
If the trouble stays after these checks, call us and describe what you found.
How Commercial HVAC Work Goes
- You call, we dispatch. Describe the property, the units, and the trouble.
- We test the full system. We walk the site and check each unit, the roof access, the ductwork, and the controls.
- We explain in plain language. We walk you through what we found and lay out repair or planned maintenance, including how the work fits around business hours.
- We fit parts matched to your units. We restore failed parts, clean coils and filters, and test each unit through a full cycle.
- We verify before we leave. You get a plain-language report for each unit, plus the filter sizes and change schedule for the building.
What You Can Expect
Expect work planned around the business. We set the visit so the noisiest work lands outside peak hours when the building allows it, and we keep roof and mechanical areas tidy. Expect a clear explanation before any work starts, and a report for each unit when the visit ends.
After the visit, keep roof access clear, keep filters on the schedule we show you, and tell us about any room that drifts hot or cold. A planned maintenance schedule keeps every unit checked before its heavy season.
How Commercial HVAC Compares With Residential Service
Commercial and residential HVAC share the same parts and the same faults. The difference is scale: more units, longer run hours, and more zones to balance. A business that also needs fresh-air ventilation may suit an ERV, and a business with stale or dusty indoor air may need the broader work on the indoor air quality page. For a heating or cooling failure that cannot wait, see emergency HVAC repair.
Frequently Asked Questions
We serve offices, shops, restaurants, clinics, rentals, and hotels and motels across Colorado. If the building has rooftop units, split systems, ductwork, or PTAC units, we can look after them. Tell us about the property when you call so we can plan the visit.
Yes. We diagnose and repair rooftop package units, including capacitors, contactors, fan motors, coils, refrigerant leaks, and controls. We also check the curb, the duct connections, and the drain, since roof water and debris cause their share of trouble.
We set the visit so the noisiest work lands outside peak hours when the building allows it. Tell us the open hours, the busy periods, and any rooms that must stay quiet, and we plan the work around them.
A commercial maintenance visit checks each unit: coils, filters, drains, electrical parts, refrigerant charge, and airflow. We clean what needs cleaning, test each unit through a full cycle, and leave a plain-language report for each unit.
Yes. We service PTAC units for hotel and motel properties, including coil and filter cleaning, drain clearing, fan and control repair, and replacement of units that no longer hold temperature. Tell us how many rooms the property runs when you call.
Replacement makes sense when a unit breaks down again and again, cools or heats weakly even after repair, or runs with parts that are hard to source. We lay out repair and replacement in plain language so you can decide what fits the building.
