GET STARTED
Schedule a Commercial HVAC Consultation
Your commercial building's heating and cooling needs are unique to your specific facility, occupancy patterns, and operational goals. Let our team assess your current system, identify efficiency opportunities, diagnose energy waste, and design a solution that fits your budget and operational timeline. Whether you need repairs, planned maintenance, or a complete system replacement, we're here to guide you through every step.
OUR PROCESS
Our Commercial HVAC Service Process
We begin with a thorough evaluation of your existing commercial HVAC infrastructure, including rooftop units, boiler systems, controls, and ducting. Our technicians document system age, condition, efficiency metrics, and operational patterns to understand your actual energy use and performance gaps. This assessment is the foundation for all decisions—whether you repair, maintain, or replace.
- Inspect rooftop units (RTUs) and boiler installations for safety, structural integrity, and efficiency
- Review full maintenance history to identify recurring service needs and pattern failures
- Test system controls, thermostats, zone management, and automatic reset mechanisms
- Measure actual operating temperatures, airflow patterns, and differential pressure across zones
- Analyze energy consumption data and identify efficiency losses tied to equipment condition
- Generate detailed findings report with photos, measurements, and recommendations for your facilities team
Based on our assessment, we design a solution that aligns with your building's comfort needs, energy goals, and budget constraints. We specify appropriate commercial-grade equipment, sized correctly for your space and usage patterns. A properly sized system is more efficient, requires less maintenance, and costs less to operate over its lifetime.
- Calculate proper system capacity for your facility size, occupancy, layout, and usage patterns
- Model seasonal heating and cooling loads to select the right equipment tonnage
- Select Armstrong Air, Ducane, Mitsubishi, or Fujitsu units matched to your operating environment
- Provide detailed equipment specifications, efficiency ratings (SEER/HSPF/AFUE), and warranty terms
- Present multiple options with side-by-side cost-benefit analysis so you can choose the best value
- Coordinate timing and installation scheduling around your business hours and peak operations
Our experienced commercial technicians perform all work to manufacturer specifications and building codes, ensuring your system operates at peak performance and maintains full warranty protection. For new installations, we handle all structural, electrical, and controls integration. For repairs, we diagnose root causes and fix problems permanently, not just the symptom.
- Skilled installation of rooftop units with proper structural bracing, vibration isolation, and weathersealing
- Light commercial boiler installation with complete piping design, expansion tank sizing, venting, and controls integration
- All ductwork sizing, sealing, and insulation to eliminate leaks and maximize efficiency
- Electrical wiring, circuit protection, and control system connections to specification and code
- Removal and proper disposal of old equipment per environmental and EPA refrigerant standards
- Complete system startup, calibration, control testing, and operational verification under load
Once your new or repaired system is in place, we perform comprehensive testing to confirm all components operate safely and efficiently. Your facilities team receives complete documentation and operational training for your new system, setting you up for successful long-term operation.
- Run full system diagnostics across all zones, controls, and safety interlocks
- Test heating and cooling performance under full load conditions across all operating modes
- Verify all safety controls, emergency shutoff mechanisms, and pressure relief devices
- Provide complete equipment documentation, warranty cards, parts diagrams, and maintenance schedules
- Brief your facilities manager or maintenance team on routine maintenance, filter changes, and seasonal operation
- Leave detailed service records, baseline performance data, and contact info for future reference

Scheduled commercial maintenance keeps your system running reliably and extends equipment life significantly. We offer flexible maintenance plans that fit your budget and building's operational demands, reducing unplanned repairs, extending system lifespan, and controlling energy waste. A well-maintained commercial system delivers years of reliable service.
- Quarterly or seasonal preventive maintenance inspections aligned with your operating calendar
- Filter replacements, coil cleaning, and electrical connection checks during each visit
- Early detection of worn components before failures occur—preventing costly unplanned repairs
- Performance reporting and trending so you track system health and energy costs over time
- Priority scheduling for your repairs so we coordinate around your preferred downtime windows
- Ongoing technical support from technicians who know your specific system and history
Many commercial properties can reduce energy waste significantly through better controls, not just new equipment. We evaluate your existing thermostats, zoning, and building automation setup and recommend upgrades—programmable scheduling, zone dampers, and economizer tuning—that help your system run only as hard as it needs to, when it needs to.
- Review of existing thermostat and zoning configuration for missed efficiency opportunities
- Programming recommendations aligned with your building's actual occupancy schedule
- Economizer and damper inspection to confirm free-cooling opportunities aren't being wasted
- Guidance on integrating new equipment with existing building automation systems where applicable

COMMON QUESTIONS
Commercial HVAC Questions Answered
The right RTU size depends on your building's square footage, insulation, occupancy levels, and climate zone. MH HVAC performs a detailed calculation during our assessment to specify the correct tonnage—oversized units waste energy and money, while undersized units leave your building uncomfortable. We size all RTUs according to commercial HVAC engineering standards to ensure efficient operation.
Commercial buildings typically benefit from scheduled maintenance aligned with seasonal changes—spring before cooling season and fall before heating season, plus mid-season checks. Heavily used or continuously operating buildings may need more frequent service. We customize a schedule for your building's actual usage patterns and performance history.
With proper maintenance, commercial rooftop units and boilers can provide many years of reliable service life. Neglected systems fail much sooner and suffer greater repair costs. Preventive maintenance is one of the most cost-effective ways to maximize equipment life and avoid costly replacements.
It depends on the system's age, repair history, and efficiency compared to replacement cost. When repair costs start approaching the cost of a new system, replacement often makes more financial sense. We provide honest diagnostics and present both repair and replacement options so you can make the best business decision for your property.
Yes. We install, repair, and maintain light commercial boiler systems for heating applications. From initial specification and installation through ongoing seasonal maintenance, we ensure your boiler system operates safely and efficiently. Commercial boilers require professional service to stay reliable—we handle that expertise.
Our commercial maintenance plans provide scheduled preventive service, priority scheduling, and may include discounts on parts and labor. For property managers, the real value is predictability—you know your annual HVAC cost, reduce the chances of unexpected repairs during peak seasons, and maximize equipment uptime.

Leaky or poorly insulated ductwork is one of the most common sources of commercial energy waste. Signs include uneven temperatures between rooms or floors, rooms near ductwork that feel drafty, and rising utility bills without a change in usage. We inspect accessible ductwork during our assessment and recommend sealing or insulation improvements where they'll make the biggest difference.
Yes. We service rooftop units, light commercial boilers, and ductless commercial systems, so most buildings can rely on a single HVAC partner for every piece of equipment on the property.
