Controla la temperatura

Surplus temperature controls for HVAC are brand-new, never-installed components sourced directly from manufacturers in bulk and then sold at prices well below traditional supply house pricing. The inventory includes thermostats, aquastats, high-limit controls, fan and limit switches, defrost controls, and other devices that regulate temperature in heating and cooling systems. "Surplus" refers to how the product was sourced (manufacturer overstock and excess inventory), not the condition of the item. Every control arrives in the original manufacturer’s packaging.

Yes. Discount HVAC temperature controls at Surplus City Liquidators are the same brand-name, new-in-box products available at traditional supply houses. The lower price reflects bulk purchasing and lean overhead, not a difference in product quality or condition. Each item is sourced directly from manufacturers and arrives in original packaging unless otherwise noted in the product listing.

The collection includes a wide range of controls for residential and light commercial applications. You'll find surplus HVAC thermostats in both programmable and non-programmable configurations, plus aquastats, capillary-style temperature controllers, fan and limit controls, defrost controls, and refrigeration cold controls. If you need a programmable thermostat surplus option or a specific aquastat surplus HVAC control, check current listings. Brands and model numbers vary with available inventory and move quickly.

Review the product listing carefully for voltage requirements (24V vs. line voltage), staging (single-stage vs. multi-stage), and system type compatibility (heating only, cooling only, or heat/cool). Key specs to match include temperature range, wiring terminals, and control type. Note the make and model of your existing equipment before purchasing. A licensed HVAC technician can confirm compatibility if you're uncertain.

Buying cheap temperature controllers for HVAC through Surplus City means the same brand-name, new-in-box product you'd get through a distributor, without the distributor markup. The savings come from bulk sourcing and lower overhead, not from a difference in the parts themselves. For contractors running large service jobs or multi-unit replacements, the cost difference on a full order of controls can be significant. Inventory moves quickly, so checking current listings before placing an order is recommended.

Surplus City Liquidators ships to all 48 contiguous states via ground, LTL, and other carrier options. Orders are processed within 3–5 business days, with shipping costs calculated by method and carrier at checkout. In-person pickup is available at various showroom locations. Check online for availability.

Confirm the replacement matches the original control's voltage, temperature range, and wiring configuration before installation. For capillary-style controllers, verify that capillary length and bulb dimensions fit your equipment housing. Installation of HVAC controls should be performed by a licensed HVAC technician to ensure safe operation and system warranty compliance.
