Updated September 2026

Quick answer

What HVAC system fits a mobile home in Jacksonville, FL?

Mobile and manufactured homes around Jacksonville usually use a package unit beside the home or a split heat pump with an indoor electric furnace, connected to ducts under the floor. Equipment should be approved for manufactured housing, sized to the home, and the belly ducts checked for leaks.

Overview

Manufactured homes have their own rules

Mobile and manufactured homes are built differently from site-built houses. Ducts usually run through the belly under the floor, the indoor unit often sits in a small closet, and the home's structure limits what can be installed and where. Equipment needs to be suitable for manufactured housing.

We look at how the home is set up, run a load calculation for its size and insulation, check the belly ducts and crossover, and recommend either a package unit beside the home or a split system with a compatible indoor unit. Duct leaks under the floor are common, so sealing them is part of doing the job right.

What we fix

Mobile home package unit

Many manufactured homes use a package unit sitting on a pad beside the home, connected to the belly ducts by an insulated flexible duct. Replacing one is often straightforward, but the connection under the home deserves attention, since crushed or disconnected flex duct there wastes a lot of air. We set the new unit level, run a new connection where needed, seal it properly and support it so it can't sag or tear. The home's return path is checked too, since many manufactured homes have a single small return that limits airflow.

Mobile home heat pump

A split heat pump pairs an outdoor unit with an indoor electric furnace or air handler designed for manufactured homes, usually in a hallway closet. It's a good fit when the indoor unit is in reasonable shape or when a package unit can't be placed easily. We match indoor and outdoor units, size the backup heat to the home, and set the thermostat so the heat pump carries most of the heating. Clearances around the closet door and return grille are checked so the indoor unit can breathe.

Mobile home ductwork

Belly ducts run under the floor inside the insulated underbelly, and the crossover duct connects the two halves of a double-wide. Over time the belly wrap tears, ducts separate and animals get in, so a good share of the cooling can end up under the home. We inspect what we can reach, reconnect and seal separated sections, repair the crossover, and recommend belly repair when damage is extensive. Photos of what we find under the home help you decide what repairs are worth doing, and whether a full belly repair makes more sense than patching.

Manufactured homes and the Jacksonville heat

Manufactured homes around Jacksonville face the same long, humid cooling season as site-built houses, with less insulation in many older models and ducts running through an underbelly that can tear or separate. That makes duct condition and correct sizing especially important: an oversized unit on leaky belly ducts gives a cool, damp home with high bills. We check both before recommending equipment.
