Why Choose Us
Why Dunn Businesses Choose Us for Commercial HVAC
Family-Owned Expertise & Accountability
Established in 2020, we treat your commercial HVAC system with the same care we’d give our own facility. Direct accountability means no runaround — owners who answer the phone and stand behind our work.
Commercial-Grade Parts & Equipment
We work with commercial-tier brands including Heil Elite, Navien, and Rinnai. RTUs and commercial mini-splits demand industrial components rated for continuous duty — never residential-grade substitutes.
Minimal Downtime, Scheduled Service
Every hour of downtime is revenue lost. We work around your schedule, plan maintenance windows to fit operations, and stock critical parts on-site to cut restart time and keep you informed.
Dealer & Supply Chain Credibility
As a Heil Elite Dealer, we have preferred access to commercial inventory, factory technical support, and parts availability for faster turnaround. Learn about our team.
Preventive Maintenance Programs
RTUs and commercial mini-splits work harder than residential systems. Our plans catch refrigerant leaks, electrical wear, bearing noise, and efficiency drops before they become disasters.
Fast Response for Commercial Customers
Commercial HVAC failures strike at the worst possible time — a rooftop unit down mid-season or a mini-split zone failing on your busiest day. We prioritize urgent commercial calls.

Our Commercial HVAC Service Process
Site Assessment & Diagnostics
Our technician begins with a thorough walk-through of the roof, mechanical room, or zone layout to understand the full system context. We document the current equipment, identify existing ductwork or refrigerant lines, and check for wear, corrosion, or damage. On rooftop units we also inspect the curb, flashing, and condensate drainage — a leaking curb seal or clogged drain pan does as much damage as a failed compressor. If you have air conditioning or heat pump systems in parallel, we assess the full facility ecosystem.
- Examine RTU nameplate, serial numbers, and service history
- Test electrical connections, control wiring, and safety interlocks
- Measure refrigerant pressure and subcooling against OEM spec
- Check compressor amp draw, motor winding resistance, and bearing noise
- Inspect economizer dampers, actuators, and free-cooling changeover
- Review roof curb seal, flashing, and condensate drain pan for leaks
- Review thermostat logic, zone control programming, and setpoint history
- Photograph nameplate data and any visible damage for documentation
System Testing & Performance Baseline
Before any work begins, we establish a performance baseline that becomes your reference for improvement. For RTUs, we measure cooling/heating capacity, airflow volume, and electrical energy draw. For commercial mini-splits, we test each zone’s temperature differential, refrigerant pressures, and zone control response. This baseline creates a measurable standard: if performance doesn’t match specs after service, we spot it immediately and correct it before we leave.
- Log supply and return air temperatures across all zones
- Confirm CFM output with calibrated anemometer
- Verify electrical phase, voltage, amperage, and power-factor readings
- Document any unusual vibration, noise, or thermal patterns
- Record baseline energy consumption and efficiency metrics
- Create baseline video or photographs showing control response and system state
Maintenance or Repair Execution
For preventive maintenance, we clean coils, replace filters, verify refrigerant charge, lubricate motors and bearings, and inspect electrical terminals. On belt-driven RTU blowers we check belt tension and alignment and confirm variable-frequency drives ramp correctly. On commercial mini-splits we inspect branch boxes, pressure-test line sets, and confirm each indoor head reports back to the controller. For repairs, we diagnose the root cause and replace failed components with OEM-equivalent industrial-grade parts rated for continuous operation. Whether you operate RTUs, mini-split systems, package units, or hybrid configurations, we keep your equipment spec-compliant.
- Clean indoor and outdoor coils with approved chemical or pressure wash
- Replace air filters and access panels
- Inspect blower belts, bearings, and VFD operation on rooftop units
- Check mini-split branch boxes and pressure-test line sets for leaks
- Recharge refrigerant to manufacturer spec if needed
- Tighten electrical connections and verify terminal torque specs
- Replace worn motors, capacitors, contactors, or control boards
- Test repaired components under load before finishing
Post-Service Testing & Documentation
Once service is complete, we run the same test sequence as before to confirm performance matches the baseline or exceeds original specs. If testing reveals any discrepancy, we troubleshoot and correct it before final sign-off. You receive a detailed, itemized service report documenting what was done, what was found, what was replaced, and specific recommendations — supporting your equipment lifecycle planning.
- Re-test cooling/heating output against baseline and manufacturer spec
- Verify thermostat and zone controls respond correctly to setpoint changes
- Confirm refrigerant charge matches spec using accurate scales and gauges
- Document all service activities, parts replaced, labor hours, and materials
- Provide customer-facing report with before/after performance comparison
- Photograph final system state and control settings for your records
Preventive Plan & Follow-Up
Commercial systems benefit from scheduled maintenance every 6–12 months depending on usage, climate, and environment. We set up recurring service windows, stock commonly needed parts, and alert you to upcoming inspections. This approach prevents breakdowns, extends equipment life by 3–5 years, and gives you predictable service costs. Where your facility runs a building automation system or programmable thermostats, we review occupancy schedules and setback strategies so your equipment isn’t conditioning empty space.
- Recommend optimal maintenance frequency based on equipment type and usage
- Review BAS and thermostat scheduling for occupied and unoccupied setbacks
- Document the next scheduled service window and coordinate with facilities team
- Set up automated calendar reminders if requested; provide scheduling flexibility
- Provide parts inventory estimates so you can budget for replacements
- Brief your facilities team on system care between service visits
- Offer online portal or email summaries for tracking maintenance history

Commercial HVAC Questions & Answers
An RTU is a self-contained HVAC system installed on a building’s roof. It combines air conditioning, heating, and ventilation in one packaged unit with no indoor mechanical room needed. Businesses like RTUs because they save interior space, simplify installation on retrofit buildings, and are easy to replace when end-of-life arrives.
Commercial RTUs should receive preventive maintenance twice yearly: once before summer cooling season (May–June) and once before winter heating season (September–October). If the unit runs continuously or operates in a dusty environment, quarterly service is recommended. This frequency catches refrigerant leaks, electrical wear, and coil fouling early.
Commercial mini-splits use the same ductless refrigerant-line technology as residential units but are rated for higher capacity, longer run times, and heavier-duty environments. Commercial units handle larger zones, support multi-zone configurations, and use commercial-grade refrigerants and electrical components. Our Heil Elite commercial mini-splits are built for continuous operation.
Retrofit controls are possible if the RTU’s compressor and coils are still sound, but we evaluate whether the savings justify the cost. Many units over 15 years old consume so much energy that a new unit pays for itself in 4–6 years. We provide a repair-versus-replacement analysis and let the ROI guide the decision.
We are a Heil Elite Dealer specializing in Heil commercial units. We also service and install Navien and Rinnai equipment. All three brands are industrial-duty manufacturers trusted by commercial HVAC contractors. We stock parts and have access to factory technical support, reducing downtime.
Signs include: uneven cooling or heating across zones, longer run times to reach set temperature, ice on outdoor coils in cooling mode, or higher-than-normal electricity bills. We perform a charge test using electronic scales and pressure gauges. If you notice a performance drop, don’t delay — low refrigerant stresses the compressor and can cause catastrophic failure.
Yes. We provide fast response for commercial customers with critical HVAC needs. Call (919) 820-4408 during business hours to discuss priority coverage options or contact us online to set up a service plan.
A solid plan includes: seasonal pre-service inspections (spring and fall), coil cleaning, filter replacement, refrigerant pressure and electrical testing, lubrication of motors and bearings, and a written service report. Some customers add monthly walk-throughs during peak seasons. We customize plans to match your facility’s usage and risk tolerance.
Our financing page details available options. Many commercial customers arrange finance through our Optimus partnership, which offers terms for equipment and service. Contact us to discuss commercial financing and seasonal payment plans.
Yes. Commercial RTUs and mini-splits move air, but air quality depends on filtration, humidity, and fresh-air intake. We assess your current setup and recommend upgrades like MERV-13 filters, humidity controls, or ERV (energy-recovery ventilation) systems. Poor air quality increases sick days; even small upgrades improve employee comfort and retention.
