It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST24BU13 — a factory-installed evaporator coil. It pairs with an outdoor condenser (for cooling only) or a heat pump (for both heating and cooling). Unlike a gas furnace, an air handler does not burn fuel; it relies on the refrigerant system and\/or supplemental electric heat kits for heating.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-item\"\u003e\n\u003cdiv class=\"gm-faq-q\"\u003eWhat's the difference between an air handler and a gas furnace?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA gas furnace burns natural gas or LP to produce heat; an air handler doesn't have a burner. Air handlers are the typical indoor partner for heat pump systems, and are also used in all-electric homes where electric heat strips provide the heating. If you have natural gas service and prefer gas heat, a furnace is likely the right choice; if you're installing a heat pump or going all-electric, an air handler is the match.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-item\"\u003e\n\u003cdiv class=\"gm-faq-q\"\u003eWhat size home does a 1.5-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 1.5-ton air handler is generally appropriate for homes in the 750–1,100 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing.

The AMST24BU13 is designed to accommodate field-installable electric heat kits (sold separately). Heat kits are commonly added for supplemental backup heat when paired with a heat pump in cold climates, or as the primary heat source in all-electric homes. Your HVAC contractor will select the correct kW rating based on your home's heating load and local electrical service.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-item\"\u003e\n\u003cdiv class=\"gm-faq-q\"\u003eCan I use this with an R-410A condenser?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eNo. The AMST24BU13 is engineered exclusively for R-32 refrigerant systems and is not compatible with R-410A or R-22 outdoor units. R-32 has different operating pressures and oil compatibility — mixing refrigerants will damage equipment and void warranties. Pair only with an R-32 condenser or heat pump.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-item\"\u003e\n\u003cdiv class=\"gm-faq-q\"\u003eHow do I know if this cabinet size fits my installation?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eGoodman cabinet widths: A = 14\", B = 17-1\/2\", C = 21\", D = 24-1\/2\". The AMST24BU13 is a Cabinet B (17-1\/2\" wide). Cabinet size matters for both the physical installation space and, if you're replacing an existing unit, the ductwork connections. Your HVAC contractor can verify fit against your layout.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-item\"\u003e\n\u003cdiv class=\"gm-faq-q\"\u003eHow do I register for the 10-year warranty?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eRegister the unit online at Goodman's warranty registration page within 60 days of installation. You'll need the model number (AMST24BU13), serial number (found on the data plate), installation date, and installing contractor information. Without registration, the warranty reverts to a shorter base term.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cp style=\"text-align:center;color:#6b7280;margin:48px 0 0;font-size:14px;\"\u003eDesigned, engineered, and assembled in the U.S.A. by Goodman Manufacturing — a member of the Daikin group.\u003c\/p\u003e\n\n\u003c\/div\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":43725540819009,"sku":"AMST24BU13","price":1471.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/6279\/8913\/files\/AHU-Image_0425b790-eb9d-4e03-bff5-c5d5aecfc5bd.jpg?v=1775676808","url":"https:\/\/aceairdirect.com\/products\/goodman-amst-r32-24bu13","provider":"Ace Air Direct","version":"1.0","type":"link"}
