At 266,000 BTU on 208\/230V 3-phase power with medium heat gas output, this commercial rooftop packaged unit is the specification for major retail complexes, flagship distribution and fulfillment centers, large manufacturing support facilities, substantial institutional campuses, and major multi-tenant commercial developments in moderate climate zones — the Mid-Atlantic, Pacific Northwest, lower Midwest, and transitional climate markets — where the cooling load has reached the ceiling of the Foundation Series standard voltage lineup, winter heating demands are genuine and sustained enough to require medium heat output, and the building's 208\/230V electrical infrastructure makes this the highest-capacity correctly specified unit available on standard commercial power.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe medium heat configuration at 25-ton capacity on 208\/230V power closes the Foundation Series medium heat 208\/230V lineup at its most consequential specification point. At 266,000 BTU cooling output — the highest rated capacity in the Foundation Series on standard voltage — the heat configuration decision carries its greatest long-term financial and operational significance. Low heat at this tonnage in a moderate climate building leaves heating capacity short during the coldest sustained periods of a genuine moderate climate winter — not the brief cold snaps of warm climate markets, but the extended cold periods that moderate climate commercial buildings in the Mid-Atlantic, Pacific Northwest, and lower Midwest face regularly across a full heating season. High heat at this tonnage in a moderate climate building adds the most significant fuel consumption overhead in the Foundation Series lineup — a high heat system at 25-ton capacity running through moderate winters will rarely operate near its rated output, generating avoidable operating costs across every heating season of the equipment's service life. Medium heat resolves both risks at the top of the lineup — full winter heating coverage for the coldest sustained conditions a moderate climate commercial building will face, without the overhead of heat capacity the climate will never demand.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 13.0 IEER, this unit holds the same efficiency tier as the 20-ton medium heat entry — consistent across the upper Foundation Series tonnage tier at maximum capacity and above minimum energy code thresholds in most U.S. jurisdictions at 25-ton scale. For large moderate climate building owners running 25-ton equipment through balanced annual heating and cooling cycles, 13.0 IEER at 266,000 BTU medium heat output on standard voltage represents the highest absolute dollar value of efficiency performance in the Foundation Series medium heat 208\/230V lineup — maximum tonnage, balanced annual runtime across both seasons, and the largest single-unit utility spend in the standard voltage lineup combine to make the efficiency rating at this capacity tier more financially impactful per efficiency point than at any lower tonnage in the medium heat 208\/230V series. R-454B refrigerant at 25-ton medium heat capacity on standard voltage is the most consequential refrigerant specification decision in the Foundation Series 208\/230V lineup — at maximum tonnage in a moderate climate building running meaningful annual heating and cooling cycles, the cost and disruption of a mid-lifecycle refrigerant retrofit at 25-ton scale across both seasons of operational dependency makes R-454B at installation the specification decision that protects the building owner's investment most completely across the full equipment service life.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eSpecifications at a Glance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"overflow-x-auto w-full px-2 mb-6\"\u003e\n\u003ctable class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\"\u003e\n\u003cthead class=\"text-left\"\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\"\u003eSpec\u003c\/th\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eCapacity\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e25 Ton \/ 266,000 BTU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eHeat Configuration\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eMedium Heat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eIEER\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e13.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eRefrigerant\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eR-454B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eVoltage\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e208\/230V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003ePhase\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e3-Phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eHeating\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eGas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eCooling\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eElectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eStages\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eSingle Stage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eSeries\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eFoundation Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Trane","offers":[{"title":"Default Title","offer_id":55234277671203,"sku":"GDK300A3SMA1DQY","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/1171\/5363\/files\/TraneGDK_9e5fd715-ae92-4ad3-860d-1ac9ce180485.png?v=1781331538","url":"https:\/\/www.acunitsforless.com\/products\/trane-25-ton-commercial-gas-electric-packaged-unit-foundation-series-medium-heat-r454b-208-230v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
