At 240,000 BTU on standard commercial voltage with medium heat gas configuration, this commercial rooftop packaged unit is engineered for major retail anchors, large institutional campuses, substantial office complexes, large houses of worship, and high-occupancy commercial facilities in moderate climate zones — the Mid-Atlantic, Pacific Northwest, lower Midwest, and transitional climate markets — where the cooling load has pushed to the 20-ton tier, winter heating demands are real and sustained enough to require medium heat output, and the building runs standard 208\/230V 3-phase commercial power. At 20-ton medium heat on standard voltage, this unit addresses the largest moderate climate commercial buildings where low heat undershoots winter demand and high heat overshoots it — medium heat at maximum standard-voltage Foundation Series upper tier capacity is the specification that gets the annual load profile right across both seasons in large moderate climate commercial buildings.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe medium heat configuration at 20-ton capacity on 208\/230V power carries particular specification significance at this tonnage tier. Large moderate climate commercial buildings that have outgrown 17.5 tons are substantial facilities — high internal heat loads, significant exterior envelope exposure, and sustained peak cooling demand through warm months — but they operate in climates where winter conditions are moderate rather than severe. At 240,000 BTU cooling output, specifying low heat in a moderate climate building leaves heating capacity on the table during the coldest weeks of the shoulder season, while specifying high heat adds fuel consumption overhead across a heating system that will rarely operate near its rated output through moderate winter conditions. Medium heat at 20 tons resolves both risks simultaneously — full winter heating coverage for moderate climate conditions without the operating cost overhead of a heat configuration sized for cold climate severity the building will never experience.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 13.0 IEER, this unit steps to the upper tier efficiency rating consistent with the 20-ton Foundation Series entries across all heat configurations — the step from 14.0 IEER at 17.5 tons to 13.0 IEER at 20 tons reflects the engineering realities of delivering 240,000 BTU through a single-stage gas\/electric rooftop package and is consistent with commercial efficiency standards at this capacity level. For large moderate climate building owners running 20-ton equipment through balanced annual heating and cooling cycles, 13.0 IEER at 240,000 BTU medium heat output still delivers meaningful operating cost efficiency at the scale where utility spend on a single rooftop unit is most significant — and sits above minimum energy code thresholds in most U.S. jurisdictions at this tonnage. R-454B refrigerant at 20-ton medium heat capacity on 208\/230V power eliminates the most disruptive mid-lifecycle service risk the building owner faces — a forced refrigerant retrofit on a 20-ton commercial unit mid-service-life in a large moderate climate building running balanced annual HVAC cycles, where both heating season and cooling season system availability carry genuine operational and financial consequences.\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\"\u003e20 Ton \/ 240,000 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":55234272592163,"sku":"GDK240A3SMA1DQY","price":29950.0,"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-20-ton-commercial-gas-electric-packaged-unit-foundation-series-medium-heat-r454b-208-230v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
