Define the equipment, affected space, and business priority.
Restaurants, retail, offices, medical spaces, churches, and schools have different occupied schedules. Identify each unit and the approval contact instead of treating every rooftop visit as the same task.
A unit or business space is down
Identify the equipment and occupied area, then assess the fault and repair scope.
Useful details: Provide operating hours, roof access, tenant coordination, and an approval contact.
Plan equipment replacement
Consider capacity, controls, roof access, lifting arrangements, and any additional trade coordination.
Useful details: Share unit schedules, model labels, service history, and the intended work window.
Organize preventive care
Define the units covered, tasks, visit schedule, reporting, and approval of repairs beyond routine care.
Useful details: Keep an equipment list and note recurring faults separately from maintenance tasks.
How we approach commercial HVAC.
A symptom describes what you notice, not necessarily which part has failed. These are the questions and checks that help define the next step for your equipment.
Identify the affected equipment
Commercial spaces may use multiple units or separately controlled zones. Provide the business address, equipment label if known, and the areas affected. We service rooftop and packaged units up to 25 tons. Distinguishing an equipment fault from a control or distribution issue helps define the work.
Breakdown diagnosis
The diagnostic scope follows the symptoms and equipment. Electrical components, controls, airflow, drainage, refrigerant performance, and the heating section may require attention. Describe fault codes, noises, recent work, and whether several units stopped together. We explain findings before recommending repair.
Rooftop access and site coordination
Arrange roof access and identify site rules, parking, alarms, tenant contacts, and the person authorized to approve work. Lifting equipment or restricted access can affect scheduling and the installation scope. Discuss operating hours and which areas must remain available to staff or customers.
Commercial replacement planning
A proposal should cover the equipment, capacity, controls, electrical needs, curb or duct transitions, removal, startup checks, and warranty terms. A like-for-like swap may not address a change in occupancy or use. Free replacement estimates give you a basis for comparing complete scopes.
Maintenance contracts
Identify the units covered, tasks, visit schedule, reporting, and approval of additional work. Good records can make repeat faults and equipment-condition changes easier to investigate. The maintenance record helps identify developing issues and plan follow-up repairs.
Emergency business service
ARP provides 24/7 emergency HVAC service with no overtime fees. Call with the address, equipment, and business impact so current availability can be confirmed. We discuss the repair, parts availability, and any follow-up rather than promise a fixed arrival or completion time.
Your service visit, step by step.
- Describe the issue. Share your address, equipment type, symptoms, and contact details. For urgent service, call (405) 413-0583.
- Understand the findings. We assess the equipment and explain what the recommended work addresses. Ask about alternatives if you are comparing repair and replacement.
- Review the scope and price. Confirm the included work, parts, warranty terms, and any required follow-up before authorizing the job.
- Know the next step. Some work can require ordered parts, separate installation planning, or a return visit. We explain those requirements rather than promise the same outcome for every property.
ARP is licensed and insured, holds Oklahoma CIB license #00125054, and is BBB Accredited with an A+ rating. We offer 24/7 emergency service, no overtime fees, and free replacement estimates.
Equipment details that make the visit more useful.
Rooftop and packaged HVAC units up to 25 tons, plus heating and cooling equipment serving restaurants, retail, offices, medical spaces, churches, and schools.
A model label, the symptom history, and previous repair paperwork help identify the installed system. Our gallery includes actual Goodman and Mitsubishi equipment; a photograph alone does not establish a diagnosis or a warranty entitlement.
Before approving work.
Ask for the repair or installation scope, included parts and equipment, the price, and any follow-up. For replacement, review manufacturer coverage, registration requirements, and the offered labor terms in the written proposal. The terms for your actual equipment and work govern coverage.
