Frequently Asked Questions
Surplus City Liquidators carries a range of surplus rooftop unit accessories sourced as brand-new, never-installed stock directly from manufacturers. The collection includes structural and protective components: roof curbs, rooftop unit curb adapters, mounting brackets, protective equipment covers, hail guards, vibration isolators, and drain pans.
Inventory shifts as new manufacturer lots are acquired, so the collection reflects what is available at any given time. Contractors and facilities teams planning commercial RTU installations or replacements will typically find the structural and protective accessories needed to complete the job.
Every item sold by Surplus City Liquidators is brand-new and never installed, not used, pulled, or refurbished. Surplus inventory comes from direct manufacturer purchases in large quantities, which is what makes below-retail pricing possible without any compromise to product condition.
Buyers can expect full factory condition across all rooftop accessories in the collection. The term "surplus" refers to the sourcing channel, not the condition of the equipment.
The correct packaged unit roof curbs or adapter is determined by the RTU footprint dimensions, supply and return duct opening positions, tonnage, and orientation, not by efficiency ratings or BTU output. When replacing an older unit with a new one of different dimensions, a curb adapter bridges the gap between the existing roof opening and the new unit base rail, avoiding the need to modify the roof deck or existing ductwork.
Have the full unit model number, tonnage, supply and return orientation, and existing curb dimensions on hand before selecting. If you are unsure which product fits your application, the team at any of the four Surplus City Liquidators showroom locations, in Lebanon, IN, Lafayette, IN, Grand Prairie, TX, and Greenville, SC, can assist.
Surplus City Liquidators ships RTU mounting accessories and structural components to all 48 contiguous states, with freight options including ground, LTL (less-than-truckload), flatbed, and ship-to-terminal for larger items like roof curbs. Orders are typically processed within three to five business days, and a tracking number is provided once the order ships.
In-person pickup is also available at any of the four showroom locations: Lebanon, IN, Lafayette, IN, Grand Prairie, TX, and Greenville, SC. For oversized freight items, ship-to-terminal delivery is often the most practical option for buyers outside the Indianapolis metro area.
Sourcing discount HVAC rooftop parts through a surplus dealer that buys directly from manufacturers in bulk consistently yields prices below what contractors pay at traditional supply houses or through distributor channels. Surplus City Liquidators buys brand-new inventory directly from manufacturers and passes those savings through to contractors, facilities managers, and property owners.
Exact savings vary by item and brand, but the surplus model is built around eliminating middlemen. All inventory is brand-new and never installed, so buyers get below-retail pricing without any trade-off in product condition.
Rooftop unit protective covers and hail guards defend condenser coil fins against hail impact, airborne debris, and weather exposure year-round. Unprotected coil fins are vulnerable to bending from hail strikes, which restricts airflow and reduces system efficiency over time.
Hail guard netting and protective covers are lightweight, retrofit-friendly accessories that extend the service life of an RTU between scheduled maintenance intervals. In hail-prone regions, they are a cost-effective investment compared to coil repair or replacement costs that follow a significant storm. All protective covers and hail guards in the Surplus City Liquidators collection are brand-new and never installed.
Manufacturer warranties are not included with surplus rooftop accessory purchases, which is standard across the surplus HVAC parts market. Surplus City Liquidators offers an optional 30-day startup warranty, purchasable for $30, that applies to eligible undamaged residential single-phase items not covered under any manufacturer warranty.
If a covered item proves inoperable within the first 30 days after installation by a licensed HVAC technician, Surplus City Liquidators will assist in sourcing replacement parts, exchange the item if inventory is available, or issue a full monetary refund. Buyers should confirm product eligibility before purchase.
Surplus City Liquidators sells surplus packaged unit accessories to a broad range of buyers, including HVAC contractors, wholesale distributors, property managers, and building owners, with no contractor-only purchase requirement. Anyone can place an order online or visit one of the four showroom locations in Lebanon, IN, Lafayette, IN, Grand Prairie, TX, or Greenville, SC.
Rooftop structural accessories like roof curbs and curb adapters are typically installed by licensed HVAC contractors and roofing professionals to meet code requirements and protect roof warranties, regardless of where the equipment is sourced. Buyers who are unsure about local licensing or permitting requirements for their specific installation should verify with their jurisdiction before proceeding.
