All-In-One Systems to Provide Comfort Options Bryant® small packaged products deliver dependability plus performance. Our HYBRID HEAT® dual fuel systems combine the comfort of gas heat and the efficiency of an electric heat pump, while our gas furnace/air conditioner models provide warm, cozy gas heat in the winter. For all-electric comfort, choose a packaged heat pump or a packaged air conditioner.No longer trailers, manufactured homes require special equipment. Heating, ventilation and air conditioning, known as HVAC, systems can be complex in large or multistory homes; but in manufactured homes, they are one story, straight-line systems. Manufactured homes seldom come with air conditioning, especially in areas with cold winters. Adding air conditioning to an HVAC system in a newer manufactured home is a matter of adding an evaporator coil and drip pan to the existing air handler and a condenser unit alongside the building near the utility closet. Older manufactured homes may not have air handlers and require both air handler and upgraded furnace.

Turn off the furnace and turn off the electricity at the circuit box. Turn off the gas at the meter if the furnace burns natural gas. Unpack the air handler, hardware and evaporator coils, if purchased separately. Models may have different fittings and assembly requirements; read the complete directions. Separate the furnace from the plenum, where the conditioned air enters the ductwork. In manufactured homes, the plenum is under the furnace, since ductwork is typically installed under the floor. Remove one side of the air handler box. Assemble the drip pans; a “V”-shaped coil can use an L-shaped pan that mounts on the inside of the cabinet. Slide the evaporator coil onto its rails in the cabinet. It sits underneath the blower and above the exit to the plenum on a downflow mobile home system. Set the air handler over the plenum. Seal the ducts with mastic and fiberglass tape or butyl tape, as directed in the air-handler instructions. Bolt the new blower to its shelf in the air handler if you are replacing the blower in the furnace.

Tighten the bolts until they are firm; loose bolts can rattle loose. Reattach the furnace on top of the air handler. Manufacturers recommend that you match their furnaces and air handlers because they are made to fit together. If the furnace slides into the air handler box, disconnect the electrical and gas connections and reconnect them once the unit is in the cabinet. Connect the large, insulated suction tube that takes fluid to the outside condenser to the outflow side of the evaporator coil. Connect the supply line, the 3/8 to 1/2-inch copper line that brings the compressed fluid into the evaporator coils, to the thermal expansion valve (TEV or TXV) or inflow valve. Plug the blower fan in or wire it to the furnace control according to instructions in the blower package. Attach the drip line to the drip pan and run it back outside. Add the internal filters included in the air handler kit to the rack or racks near the evaporation coil. Attach external racks to the cabinet for filters if directed.

differently than those designed for traditionally constructed houses. Your heating and cooling systems should suit your manufactured home's size and type. Because of smaller air ducts and tighter corners, forced air doesn't flow as freely in a mobile home as in a larger house. That means that buyers need to ensure that the fan blower is designed to suit their specific unit. We use the terms "manufactured home" and "mobile home" interchangeably. While this is technically not accurate (mobile homes were factory-built dwellings produced before the 1976 HUD code enactment) it matches both terms' common usage. Many of the same manufacturers that make furnaces for traditional homes also sell models for mobile homes. Some brands that are available include: When shopping for manufactured home furnaces remember that standard home furnaces use different rating systems that are not relevant to a manufacturedMobile homes furnaces need to be ducted, vented, and installed differently than furnaces for site-built homes.

The ducting system in a mobile home is much smaller than in a site-built home. Mobile home furnaces use a venting system called "sealed combustion". Standard home furnaces do not take these differences into consideration and can be dangerous in a mobile home. For the sake of energy efficiency, the furnace's incoming vents should be placed where they will be able to function most effectively. For example, in a cold climate, heat ducts work best when placed around the external walls. The heating and cooling units must be built with sealed combustion to draw in outside air without releasing polluted fumes inside. Intake and exhaust vents must be sealed to prevent air from escaping. The air comes in through outlets placed in the floor, outside walls, or ceiling. Don't waste resources and money by opting for heating and cooling systems that work too hard or not hard enough to keep a pleasant atmosphere. in a more extreme climate and purchase a system that is too small and must work overtime, you'll waste energy and money.
