Keep the doors open, no matter the weather.
A heating or cooling failure inside a commercial building doesn't just cost comfort — it costs business hours. Some of the most successful storefronts, offices, and light-industrial operations in McDonough County have trusted Arnold Brothers to keep their HVAC running safely and efficiently for sixty-five years. Rooftop units, split systems, makeup-air, service contracts.
Commercial HVAC
The shop, the trucks, and the playbook — all in.
-
Rooftop unit installation
Carrier and York packaged rooftop units sized for retail, office, and light-industrial space. Replacements scheduled after hours so the business never closes its doors.
-
Split system & VRF
Split-system AC and variable-refrigerant-flow installations for buildings that need zoned comfort — different temperatures for different occupants, all on one outdoor system.
-
Service contracts
Quarterly preventive maintenance with priority response. We get to know your building, your equipment, and your schedule so problems get caught before they shut you down.
-
After-hours service
Critical repairs scheduled outside business hours whenever possible — nights, weekends, holidays. Same-day emergency response for member businesses on a service contract.
-
Makeup air & ventilation
Exhaust hoods need makeup air, occupied spaces need fresh air, and the building code says so. We design, install, and service ventilation that meets code and doesn't fight the HVAC.
-
Plant & manufacturing
Industrial-grade heating, cooling, and process ventilation for shops, warehouses, and small manufacturing. Energy audits and retrofit work to bring older facilities up to current efficiency.
Storefront, office, or shop floor — let's put a service contract on it.
