Keep your home cool and comfortable with this high quality 14 SEER air conditioning system which is designed for mobile homes and manufactured homes. The A/C system consists of the outdoor air conditioning condenser, indoor uncased evaporator coil, and 30 ft. line set, and is designed to be used with a new or existing gas or electric furnace – available separately. The condenser features a scroll compressor, easy internal access, and is charged with enough R-410A refrigerant to accommodate 15 ft. of line set. Top air discharge design and compact cabinet size are great for multi-unit placement outdoors. The matched, pressure tested indoor evaporator coil comes from the factory filled with dry nitrogen. The 30 ft. line set includes a 3/8 in. liquid line and 3/4 in. insulated suction line, and can be cut to length based on the installation application. All systems are AHRI Certified and CSA approved. Final connections from line set to coil and condenser, and system start-up must be done by a certified technician.

Sweat fit system includes: outdoor condenser, mobile home uncased indoor coil, thermal expansion valve (for some systems), and line set; a furnace or air handler is required for system operation

Condenser is factory charged with enough R-410A refrigerant for 15 ft. of line set; longer line set length requires proper charge to be added in the field by a qualified technician

The outdoor condenser has a scroll compressor which is protected internally by a high-pressure relief valve and temperature sensor, and externally by the system high pressure switch; the liquid line filter-drier is factory installed to protect the compressor against moisture and debris

The uncased evaporator coil has liquid and suction line connections with a 90° bend which is designed for mobile home and manufactured housing installation applications; this allows the refrigerant line to be connected inside the cabinet of the furnace. Please note, some coils are supplied with a TXV that meters the refrigerant, and is to be field installed

The A/C system does require a furnace or air handler to operate and circulate the air throughout the home, and may be matched with the properly sized WINCHESTER WEFC series electric furnaces available separately

30 ft. line set includes 3/8 in. liquid line and 3/4 in. insulated suction line

Should the installation require a return air coil box housing with filter, the optional WRAF-01, is available separately

[tabby title=”Sizing Guide”]


Selecting an A/C system for mobile homes is a little different than for residential housing. The following link can be used as a guide to determine the proper size equipment based on the sq. ft. and geographic location of the home. Many times the mobile home will have the equipment sizing on a data tag located near the electrical supply, or in a kitchen cabinet.
