Updated April 2026 — covers all 13+ HEAR-live states
Manufactured housing is one of the largest underserved HEAR segments. Millions of income-qualified Americans live in HUD-code manufactured homes — and most of them qualify for HEAR rebates on heat pumps, water heaters, and other upgrades. This guide covers what practitioners need to know about HEAR eligibility, installation challenges, and program navigation for manufactured home clients.
| HEAR Measure | Max Rebate | MH Eligible? | Key Consideration |
|---|---|---|---|
| Heat pump HVAC (mini-split) | $8,000 | Yes | Mini-splits are the best path — no ductwork modification. Must meet ENERGY STAR efficiency specs by climate zone. |
| Heat pump HVAC (ducted) | $8,000 | Conditional | Manufactured home ductwork is typically belly/crawl-space based — may need evaluation for mini-split vs. ducted. Duct modifications add cost and complexity. |
| Heat pump water heater | $1,750 | Space-dependent | 700+ cu ft surrounding space required. Many manufactured homes have tight mechanical closets. See space solutions below. |
| Electric panel upgrade | $4,000 | Yes | Most manufactured homes have their own service panels. 200A upgrade for electrification is a common need, especially older homes on 100A service. |
| Electric wiring (branch circuits) | $2,500 | Yes | Dedicated 240V circuits for new mini-split or HPWH installations qualify under the wiring measure. |
| Insulation and air sealing | $1,600 | Program-dependent | HEAR uses IECC 2021 R-values; HUD uses different thermal zones. State programs vary on how they handle manufactured home insulation. |
| Electric stove / induction range | $840 | Yes | Must replace fossil fuel (gas/propane) appliance. Manufactured homes are disproportionately on propane — excellent opportunity where the measure is activated. |
| Electric dryer | $840 | Yes | Must replace gas or propane dryer. Heat pump dryers preferred by some states. Ventless HP dryer is often the best fit for manufactured home laundry rooms. |
| Windows and doors | $1,200 | Yes | ENERGY STAR Most Efficient required. Manufactured home window replacement is a specialized trade — must use contractors familiar with MH window sizes and installation. |
| Smart thermostat | $250 | Yes | Standard eligibility. C-wire solutions may be needed for older manufactured home thermostats. |
Manufactured home HEAR eligibility depends on two factors: ownership of the home and occupancy as a primary residence.
| Scenario | HEAR Eligible? | Notes |
|---|---|---|
| Owner-occupant, owns home and land | Yes | Standard HEAR eligibility — same as site-built home |
| Owner-occupant, owns home, rents pad in MH community | Yes | Common in MH parks. Homeowner can apply for HEAR on the home itself, not the land. Some states may require proof of home ownership separate from land/pad. |
| Renter, rents both home and pad from park owner | No (except NM) | Standard HEAR requires owner-occupant. New Mexico allows renters at ≤150% AMI to apply directly. |
| Park owner / MH community operator applying for tenants' units | No | Same split-incentive problem as any landlord. HOMES MF track may apply for 5+ unit parks. |
| Resident owns home, home is titled as personal property (not real property) | Verify with state | Some states require the home to be titled as real property (affixed to permanent foundation) for HEAR eligibility. Chattel-titled homes may not qualify in all states. |
Mini-split heat pumps are ideal for manufactured homes because they don't require modification of the existing ductwork — and most manufactured homes have belly duct systems that would be expensive and disruptive to modify for a ducted whole-home heat pump.
| MH Size | Typical BTU Need | Mini-Split Configuration | HEAR Rebate Potential |
|---|---|---|---|
| Single-wide (~720 sq ft) | 18,000-24,000 BTU | Single 1.5-2 ton indoor unit; one outdoor unit | Up to $8,000 (subject to equipment cost) |
| Double-wide (~1,200-1,440 sq ft) | 24,000-36,000 BTU | Multi-zone 2-3 ton system with 2-3 indoor heads, or two single-zone systems | Up to $8,000 |
| Triple-wide (~1,800+ sq ft) | 36,000-48,000 BTU | Multi-zone 3-4 ton system with 3-4 indoor heads | Up to $8,000 |
The 700 cubic foot surrounding space requirement for HPWHs is the biggest obstacle for manufactured homes. A 700 cu ft space is roughly 9 feet × 9 feet × 9 feet — most manufactured home mechanical closets don't meet this threshold.
| Solution | How It Works | Requirements |
|---|---|---|
| Open utility room or bathroom | Install HPWH in a larger utility room, bathroom, or multi-purpose room with adequate cubic footage | Room must measure ≥700 cu ft; typically 8×8×11 ft minimum |
| Attached garage or addition | If the manufactured home has an attached garage or room addition, the HPWH can go there | Space must be conditioned (above freezing) year-round; HPWHs lose efficiency in very cold spaces |
| Exhaust to outside | Some HPWH models can exhaust to the outdoors, removing the 700 cu ft requirement | HPWH must support ducted exhaust; duct run must be within manufacturer spec; verify with model installation manual |
| Louvered door installation | Install a louvered door on the mechanical closet to allow air exchange with an adjacent larger room | Adjacent room must add up to ≥700 cu ft combined; some manufacturers accept this approach; verify |
| Smaller HPWH footprint | Some newer HPWH models (A.O. Smith Voltex, Rheem ProTerra) have tighter footprints that may fit in larger manufactured home closets | Measure actual closet dimensions; compare with unit footprint specs; cubic footage is the key constraint, not just floor area |
HEAR's insulation rebate uses IECC 2021 climate zone R-value minimums as the efficiency threshold. But HUD-code manufactured homes are built to a different standard — HUD Thermal Zones 1, 2, and 3 — and the two systems don't map directly.
| HUD Thermal Zone | Approximate IECC Equivalent | HUD R-Value (Ceiling) | IECC 2021 R-Value (Attic) |
|---|---|---|---|
| Zone 1 (South) | IECC Zones 1-2 | R-21 | R-30 to R-38 |
| Zone 2 (Middle) | IECC Zones 3-4 | R-33 | R-38 to R-49 |
| Zone 3 (North) | IECC Zones 5-8 | R-33 or R-40 (varies) | R-49 to R-60 |
Most manufactured home ceilings are already at or near HUD minimums, which are lower than IECC 2021 minimums in northern zones. Adding insulation to improve a manufactured home ceiling from R-33 to R-49 (IECC Zone 5 minimum) qualifies under HEAR — the work meets the efficiency threshold, even though the starting point differs from a site-built home.
Manufactured homes are disproportionately fueled by propane — roughly 10% of all manufactured homes use propane vs. 5% of site-built homes nationally. In rural areas, manufactured home propane use is even higher. HEAR's appliance measures (electric stove $840, electric dryer $840) require replacement of a fossil fuel appliance — propane counts.
A manufactured home with propane cooking and propane water heating and propane or oil heating is potentially eligible for:
Total potential: up to $15,090 — but capped at $14,000 household maximum. For an income-qualified manufactured home occupant at ≤80% AMI, this is 100% cost coverage up to $14,000. For a 80-150% AMI household, it's 50% coverage up to $14,000 in grants.
| State | MH HEAR Guidance | Key Note |
|---|---|---|
| New Mexico | Explicitly included; POS model via RebateBridge | NM allows renters to apply; manufactured home park residents who own their homes can access HEAR. High propane use creates strong electrification opportunity. |
| Massachusetts | Site-built focus in program materials, but HUD-code homes on permanent foundations are eligible per state guidance | Mass Save contractor network includes contractors experienced with manufactured homes in Western MA and rural areas |
| New York | NYSERDA HEAR covers manufactured homes on permanent foundations | NY has a large manufactured home population in rural upstate counties (St. Lawrence, Lewis, Hamilton) — high propane use, high HEAR opportunity |
| North Carolina | Energy Saver NC covers HUD-code manufactured homes; one of few states with explicit manufactured home guidance | NC has one of the largest rural manufactured home populations; strong alignment with HEAR's LMI focus |
| Wisconsin | Focus on Energy covers manufactured homes; HEAR enrollment follows same path | Focus on Energy has manufactured home weatherization experience; HEAR enrollment for weatherization contractors already serving MH market |
| Indiana | Indiana Energy Saver (HEAR) — manufactured homes on permanent foundations eligible | Rural Indiana has significant manufactured home density; propane heat common in non-gas service areas |
| Michigan | MiHER program covers manufactured homes; confirm title/foundation status | Some Upper Peninsula MH communities have high propane use; electrification opportunity is strong but HEAR-enrolled contractor access is limited |
| All other live states | Verify with state program — most accept manufactured homes on permanent foundations but have not published explicit guidance | When in doubt, call the state program helpline before starting a MH HEAR project |
