Commercial HVAC service

Understand the cause and the scope

Tell us the equipment type, approximate number of systems, access requirements, and whether the property is occupied during the proposed work. Commercial equipment and controls vary; we confirm fit and availability for the job before scheduling.

Make a confident decision

For a replacement, define the operating needs, the components being reused, and the work required around the equipment. For service, identify the person authorized to approve repairs. Written scope and clear communication help reduce surprises for the business.

Plan for the property and the people who depend on it

Commercial HVAC decisions affect occupants, operating schedules, equipment access and business continuity. S&S will define the property-specific scope, scheduling constraints and available financing before work begins.

Built for Gulf Coast conditions

Southwest Louisiana systems work through long cooling seasons, high humidity, salt-influenced air, storms and heavy rainfall. The recommendation should consider drainage, corrosion exposure, airflow and recovery after outages—not equipment capacity alone.

Equipment and registration

S&S is a Carrier - Tempstar Elite Dealer and an approved Trane Dealer. Ask which brand and model fit the project. Manufacturer registration controls eligibility for extended parts coverage. S&S submits registration where possible; the customer should retain and check the manufacturer confirmation. The manufacturer’s written eligibility and warranty terms control.

Parts coverage and workmanship coverage

Manufacturer parts coverage and S&S workmanship coverage are separate. A manufacturer parts warranty covers the part only; diagnostic labor, refrigerant, freight and miscellaneous materials are billable unless covered under the S&S labor warranty. Standard S&S coverage is one year on installation workmanship and 90 days on repairs, unless a longer period is stated in writing on the estimate or purchased as an extended labor plan. Covered workmanship corrections include labor during normal business hours. Maintenance requirements, exclusions and other written conditions apply.

Prices verified September 18, 2026. S&S confirms capability for the exact equipment and site. Refrigeration requests can include walk-in cooler or freezer controls, ice-machine controls and sensors, cleaning, water filters, equipment replacement, and R-404A or R-507 service when compatible with the equipment. Parts, refrigerant, access equipment, repairs and after-hours work are separate unless the written scope includes them.

Prepare a site brief that prevents scheduling confusion

Identify the business, equipment location, affected spaces, and the person authorized to approve work. Share any available model information and whether the request involves one system or several. Commercial properties can have equipment and access requirements that differ from a typical home, so the office confirms fit for the job.

When the request is accepted, the office will confirm the planned response window before dispatch rather than promise an unverified same-day arrival. For recurring needs, ask S&S to prepare a commercial maintenance-agreement option tied to the equipment list, operating schedule and access requirements.

Explain occupied hours, entry procedures, roof or equipment-room access, tenant coordination, and any restriction on interruptions. Those details help define a realistic scope and visit arrangement without assuming every system can be serviced under the same conditions.

• Equipment list and affected areas
• Approval contact and billing contact
• Access, occupancy, and tenant requirements
• Symptoms, operating schedule, and recent work

Keep service findings useful for the next decision

For multiple systems, ask that findings identify the specific equipment rather than only the building. Separate the repair needed now from maintenance recommendations and replacement planning. A unit-level record makes the next visit easier to understand and reduces ambiguity when different people manage the property.

For a replacement project, define the operating requirements, retained components, controls, access, and responsibilities shared with other trades. Ask how changes or additional findings are approved. Keep the final scope and equipment documentation where the responsible property contact can retrieve them.
