Commercial HVAC Preventive Maintenance

Protect Your Systems. Avoid Downtime. Extend the Life of Every Unit You Operate.

Preventive maintenance isn’t a luxury in commercial HVAC — it’s a necessity. Large-scale HVAC systems aren’t designed to run endlessly without attention. Over time, even the most advanced equipment can lose performance due to dirt buildup, refrigerant imbalances, electrical fatigue, or ignored component wear.


At Wright Brothers Inc., we deliver structured, commercial HVAC maintenance programs that keep your systems clean, calibrated, and performing at full capacity. Our preventive maintenance work reduces the risk of system failure, extends equipment lifespan, and gives you a detailed understanding of what’s working — and what needs attention — long before an outage occurs.



Commercial Maintenance That Goes Beyond Filter Changes

There’s a big difference between checking a thermostat and actually maintaining a commercial HVAC system. At Wright Brothers, we don’t just show up with a filter and a clipboard. Our maintenance crews are trained to service complex systems across commercial and industrial environments, including rooftop units, multi-zone VRFs, air handlers, make-up air systems, ERVs, and ductless mini-splits.

Our process begins with a comprehensive system evaluation during each visit. That includes:

  • Inspecting condenser and evaporator coils for dirt, damage, or obstruction
  • Testing refrigerant pressures to detect leaks or imbalances
  • Checking compressor function, electrical contactors, relays, and capacitors for wear
  • Cleaning and replacing filters with low-restriction, MERV-rated materials
  • Verifying blower motor operation, belt condition, and airflow levels
  • Examining all safety and control sequences, including economizer functions and remote system access

By treating every visit as a diagnostic opportunity — not a formality — we help our clients catch small issues before they trigger major repairs, all while keeping documentation up to date for warranty, compliance, or internal tracking purposes.

Tailored Maintenance Schedules for Every Commercial Facility

No two buildings are alike — and neither are their HVAC service requirements. Whether you’re managing an office complex, a municipal facility, a distribution warehouse, or a high-occupancy multi-use property, your systems are under different loads, schedules, and operational demands.



That’s why we develop custom HVAC maintenance programs based on your system configuration, seasonal usage patterns, and tenant expectations. Some clients require quarterly inspections with full coil cleaning and airflow testing. Others need targeted pre-season service on rooftop systems to get ahead of summer heat or winter demand spikes. We also support multi-building clients with staggered schedules to reduce operational disruption.

Our crews are dispatched regionally to ensure you see the same faces and receive consistent service over time. And each visit is logged in our service system, so you’ll always have access to complete maintenance records and insight into emerging system concerns.

OUR Process

Property teams and facility managers need more than a vendor — they need a partner who understands the day-to-day pressure of keeping tenants happy, equipment operational, and service costs predictable. That’s where our experience matters most.

When we provide preventive maintenance for commercial HVAC systems, we do it in a way that complements your operations. That includes advanced scheduling, off-peak service windows, coordinated access with on-site staff, and full reporting on each unit inspected.

For contractors or general maintenance directors overseeing capital improvement plans, our detailed records support long-term planning. When it’s time to budget for a replacement or retrofit, you’ll already know which systems are nearing the end of their reliable service life — and what the likely issues will be if left unaddressed.

SANY America – Rooftop Package Unit Replacement (2024)

Replaced a commercial rooftop unit with full coordination across trades. Worked directly with Bill Roberts Electrical for disconnect/reconnect, and Heaton Erecting for lift and placement. The project also involved control system tie-in via Ed Schoen Controls to ensure the new unit operated seamlessly with existing site protocols.

City of Griffin – Spring Preventive Maintenance (2024)

Seasonal HVAC inspections and filter changes across municipal properties. Our approach includes coil inspection, airflow measurement, and early-fault identification — helping the city keep aging systems efficient and extend equipment lifespan with proactive service.

UGA – Melton Building Unit Service (2014)

Initially called in to move a unit for a roof project. On-site, we diagnosed and repaired a refrigerant leak, replaced a failed solenoid coil, cleaned clogged condenser coils, and recommissioned the system. Full capacity restored same day. Minimal disruption to project sequencing.

Private Commercial – VRV Retrofit & Training Sync (2023)

Replaced a removed ERV with a ductless mini-split to restore local cooling. Installed hail guard on an exposed VRV system. Scheduled all work to coincide with the client’s in-house training event — executing a complete retrofit and protective upgrade in one coordinated visit.

Why Structured HVAC Maintenance Makes a Difference

Without consistent maintenance, HVAC systems degrade quietly and often invisibly — until they fail. Dirty coils lead to higher energy consumption. Failing relays cause intermittent performance issues. Undiagnosed refrigerant loss results in compressor strain and eventual shutdown.

By implementing a tailored maintenance program, you:

  • Reduce emergency calls by catching issues early
  • Lower operating costs through cleaner, more efficient system performance
  • Extend system lifespan, delaying expensive equipment replacements
  • Improve tenant comfort and system reliability, especially in extreme seasons
  • Support compliance and warranty standards with professional documentation and service records
