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.

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.

It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST30BU13 — 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 2.0-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 2.0-ton air handler is generally appropriate for homes in the 1,000–1,400 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing. A professional Manual J load calculation is the most accurate way to determine the right capacity.

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 AMST30BU13 is engineered exclusively for R-32 refrigerant systems and is not compatible with R-410A or R-22 outdoor units.

It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST36BU13 — 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 2.5-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 2.5-ton air handler is generally appropriate for homes in the 1,200–1,600 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing.

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 AMST36BU13 is engineered exclusively for R-32 refrigerant systems and is not compatible with R-410A or R-22 outdoor units.

It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST36CU13 — 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 3.0-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 3.0-ton air handler is generally appropriate for homes in the 1,500–2,000 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing.

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 AMST36CU13 is engineered exclusively for R-32 refrigerant systems and is not compatible with R-410A or R-22 outdoor units.

It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST42CU13 — 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 3.5-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 3.5-ton air handler is generally appropriate for homes in the 1,800–2,200 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing.

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 AMST42CU13 is engineered exclusively for R-32 refrigerant systems and is not compatible with R-410A or R-22 outdoor units.

It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST48CU13 — 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 4.0-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 4.0-ton air handler is generally appropriate for homes in the 2,100–2,600 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing.

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 AMST48CU13 is engineered exclusively for R-32 refrigerant systems and is not compatible with R-410A or R-22 outdoor units.

It houses the blower motor that circulates air through your home, and — in all-in-one units like the AMST60DU13 — 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 5.0-ton air handler serve?\u003c\/div\u003e\n\u003cdiv class=\"gm-faq-a\"\u003eA 5.0-ton air handler is generally appropriate for homes in the 2,500–3,200 sq. ft. range for cooling — but heating load, climate zone, insulation, and window area all affect sizing.

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 AMST60DU13 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.
