At 266,000 BTU on 208\/230V 3-phase power with high heat gas output, this commercial rooftop packaged unit is built for major retail anchors in northern markets, large institutional campuses in cold climate zones, substantial office complexes in upper Midwest and New England markets, large houses of worship in Mountain West and Great Plains cold climate geographies, and major multi-tenant commercial developments where the cooling load has reached the 25-ton ceiling, winter heating demands are at their most severe, and the building runs standard commercial voltage. When maximum Foundation Series cooling capacity and maximum Foundation Series gas heat output need to coexist in a single standard-voltage rooftop package for a large cold climate commercial building, this is the only unit in the 208\/230V lineup that delivers both at their ceiling simultaneously.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe high heat configuration at 25-ton capacity on 208\/230V power closes the Foundation Series standard-voltage cold climate lineup at its most demanding specification point. At 266,000 BTU cooling output with high heat gas output on standard voltage, this unit addresses the largest cold climate commercial buildings the Foundation Series standard-voltage lineup serves — buildings where the combination of maximum floor plate, maximum thermal mass, maximum exterior envelope exposure, maximum infiltration load during severe cold events, and maximum heating degree day accumulation across long northern U.S. heating seasons generates the most demanding combined annual heating and cooling load any standard-voltage Foundation Series unit is called upon to carry. For these buildings, the consequences of anything less than maximum gas heat output at 25-ton scale are at their absolute most severe — the largest occupied areas without adequate heat during peak cold conditions, the longest recovery windows during cold snap events, the greatest building safety exposure during extended severe cold periods, and the highest operational and financial consequences of a heating system shortfall of any standard-voltage application in the Foundation Series. High heat at 25-ton capacity on 208\/230V power is not one specification option among several at this building scale in a cold climate — it is the single correct specification that eliminates every one of those consequences permanently across the full service life of the highest-capacity standard-voltage cold climate unit in the Foundation Series lineup.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 13.0 IEER, R-454B refrigerant, and single-stage operation, this unit closes the 208\/230V high heat upper tier with full commercial energy code compliance, complete refrigerant future-proofing, and operational simplicity at the most demanding cold climate specification point on standard voltage the Foundation Series addresses. The 13.0 IEER at 25-ton capacity is consistent with the Foundation Series efficiency standard across all heat configurations at this tonnage tier — high heat specification carries no additional cooling efficiency penalty beyond the tonnage-driven step from 14.0 IEER at 17.5 tons that applies equally across low, medium, and high heat configurations at 20 and 25-ton capacity. For large cold climate building owners running 25-ton equipment at maximum annual utilization through extended northern U.S. heating and cooling seasons — the highest combined operating hour profile of any standard-voltage Foundation Series application — R-454B at installation eliminates the most consequential mid-lifecycle service event the building owner faces: a forced refrigerant retrofit on a 25-ton commercial unit in a large cold climate building where both heating season and cooling season system availability carry their maximum operational and financial consequence simultaneously, across a service life where total annual operating hours accumulate faster than in any other Foundation Series climate and heat configuration profile.\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\"\u003eHigh 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":55234313650467,"sku":"GDK300A3SHA1DQY","price":35198.0,"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-high-heat-r454b-208-230v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
