How Hawaii homes are heated
In Hawaii the main answer to the heating fuel question is “none.” The Census Bureau’s table B25117 (ACS 5-year 2020-2024) finds 148,438 of the state’s 310,247 owner-occupied homes, 47.8%, using no heating fuel. Electricity is the main fuel in another 126,536 owner homes (40.8%), and solar energy in 19,192 (6.2%). Utility gas heats 2.6% of owner homes, the lowest share of the 50 states, and bottled gas 2.1%, the second lowest.
| Heating fuel | Owner-occupied homes | Share | Source |
|---|---|---|---|
| No fuel used | 148,438 | 47.8% | ACS 2020-2024, B25117 |
| Electricity | 126,536 | 40.8% | ACS 2020-2024, B25117 |
| Solar energy | 19,192 | 6.2% | ACS 2020-2024, B25117 |
| Utility gas | 8,109 | 2.6% | ACS 2020-2024, B25117 |
| Bottled, tank or LP gas | 6,426 | 2.1% | ACS 2020-2024, B25117 |
| Wood, fuel oil, coal and other fuels | 1,546 | 0.5% | ACS 2020-2024, B25117 |
Renters look much the same. Across all 492,453 occupied homes, table B25040 (2020-2024 ACS) shows electricity as the heating fuel in 43.1% and utility gas in 3.2%.
For an HVAC buyer, the table is mainly a guide to what kind of equipment is in Hawaii homes. With so few homes on gas and so many without any heating system fuel at all, fuel-burning furnaces are uncommon, and the work centers on cooling and ventilation equipment, much of it electric: air conditioners, heat pumps and fans. The table describes the homes; it is not a measure of how many leads any group generates.
Hawaii HVAC contractor licensing
This section is general information, not legal advice. It summarizes official sources as of October 8, 2026; check the current text of each rule before relying on it.
Hawaii licenses contractors statewide through the Contractors License Board, and specialty work is sorted into numbered classes. Exhibit A of the board’s rules, HAR chapter 16-77 (DCCA copy posted February 2026), describes the classes that cover heating, cooling and ventilation:
- C-52 ventilating and air conditioning contractor: fabricates, assembles and installs warm-air heating and air cooling systems, including heating and cooling solar systems, complete ventilating systems and complete air conditioning systems, with piping, non-electrical controls, building automation and energy management, and the insulation needed within those systems. The class also covers heat pumps related to the air conditioning system.
- C-40 refrigeration contractor: installs devices, machinery and units, including ducts, blowers and thermostatic controls, that hold air temperature below 50°F in refrigerators and refrigerated rooms, and builds walk-in refrigerator boxes.
- C-44 sheet metal contractor: a broad sheet metal class whose listed work includes duct work, metal flues, free standing fireplaces and chimneys, and fiberglass ducts and fittings.
- C-61b solar heating and cooling systems contractor: installs solar heating and cooling systems, with any other specialty work that needs a license subcontracted to a contractor licensed for it.
For residential air conditioning, C-52 is the class whose description matches the work most closely. A buyer that passes Hawaii requests to contractors can check the class printed on each license against the job. Separately, technicians who handle refrigerant need certification under the federal EPA Section 608 rules.
The general license requirement and Hawaii’s door-to-door cancellation rule are covered on leads in Hawaii, so they are not repeated here.
Hawaii owners and renters for HVAC buyers
Hawaii has a large rental share. The Census Bureau’s table B25003 counts 310,247 owner-occupied homes and 182,206 renter-occupied homes among 492,453 occupied homes in the 2020-2024 ACS. An owner can approve a new air conditioning system or a heat pump on the spot, while a tenant’s request usually needs the landlord’s approval, so owner status is the first fact most buyers check.
Housing age, home values and the energy code for Hawaii are on Hawaii window replacement leads and are not repeated on this page.
Hawaii energy programs that touch HVAC work
The Hawaii State Energy Office runs the state’s federal home energy rebate program under the name eHale Energy Saver. As of October 8, 2026, the page shows the program as pending U.S. Department of Energy approval to launch, and says its two pathways, the electrification rebates (HEEHR) and the whole-home efficiency rebates (HOMES), will be available to Hawaii residents in early 2027. The HEEHR list of eligible projects includes ENERGY STAR certified heat pumps for space heating and cooling, and the page says projects must be completed by a participating contractor. The page says it will be updated when funds are available.
A second state rule concerns water heating rather than space conditioning. The energy office’s solar water heater page (checked October 8, 2026) explains that under HRS 196-6.5, no building permit is issued on or after January 1, 2010 for a new single-family dwelling without a solar water heater, unless the office’s chief energy officer approves a variance. HVAC contractors who also install water heaters meet this rule on new homes.
Hawaii counties by owner-occupied homes
Hawaii has five counties, and all of them are listed below with their owner-occupied homes and the two heating fuel answers that matter most in the state: electricity, and no fuel at all. Source: ACS 5-year 2020-2024, county tables B25003 and B25117. The figures describe housing; they do not show where leads come from.
| County | Owner-occupied homes | Heated by electricity | No heating fuel used | Source |
|---|---|---|---|---|
| Honolulu | 202,604 | 46.5% | 42.8% | ACS 2020-2024, B25003 and B25117 (county) |
| Hawaii | 54,795 | 25.5% | 62.2% | ACS 2020-2024, B25003 and B25117 (county) |
| Maui | 36,638 | 36.0% | 51.1% | ACS 2020-2024, B25003 and B25117 (county) |
| Kauai | 16,210 | 31.4% | 54.5% | ACS 2020-2024, B25003 and B25117 (county) |
| Kalawao | 0 | No owner-occupied homes | No owner-occupied homes | ACS 2020-2024, B25003 and B25117 (county) |
Honolulu County holds 65.3% of the state’s owner-occupied homes in the 2020-2024 county data and has the highest electric heating share, 46.5%. Hawaii County is at the other end, with 62.2% of owner homes using no heating fuel. Kalawao County, on Molokai, has 40 occupied homes in the same table, all renter-occupied. Solar energy is the main heating fuel for 9.0% of owner homes in Maui County, the highest county share.
Reading the Hawaii numbers for an HVAC campaign
The official figures above point to a market unlike the mainland states. Three points for a buyer planning Hawaii coverage:
- Cooling and ventilation lead. With 47.8% of owner homes using no heating fuel and only 2.6% on utility gas in the 2020-2024 ACS, furnace work is a small niche. Air conditioning, heat pump and ventilation jobs fit the housing better.
- The license class to look for is C-52. The HAR 16-77 Exhibit A description of the C-52 class covers air conditioning systems and the heat pumps that go with them, so it is the license most residential HVAC requests line up with.
- Islands differ. Honolulu County’s owner homes are more often electrically heated than those on the island of Hawaii, Maui or Kauai in the county table, and Maui has the most solar-heated homes. A buyer can set ZIP codes island by island.
None of this says how many requests arise on any island; it describes the homes and the rules.
What Hawaii HVAC buyers filter on
Hawaii HVAC buyers filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary on the same kinds of fields as other home services buyers. These are the ones that link to the Hawaii facts above:
- Project type: for example install, replace or repair, for heating or cooling. In Hawaii most buyers will weight cooling and ventilation work.
- Homeowner status: with 182,206 renter households, confirming that the requester owns the home is the first check (ACS 2020-2024, B25003).
- Timeframe: a failed air conditioner and a planned heat pump upgrade carry different urgency.
- ZIP code: buyers pick the islands and ZIP codes their crews serve, since each island is its own service area.
When HVAC opens, Hawaii buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. For the full field list, see the sample HVAC lead.
Where buyers filter in Hawaii
Each Hawaii statistical area follows county lines, so the list below also reads as a list of islands. These are the three largest by the Census Bureau’s July 1, 2025 estimates; Kauai and Kalawao counties appear in the county table above. Once HVAC opens, buyers will be able to set coverage on any ZIP code, inside these areas or outside them.
- Urban Honolulu: 988,703 (July 1, 2025 estimate)
- Hilo-Kailua (micropolitan area): 210,043 (July 1, 2025 estimate)
- Kahului-Wailuku: 160,674 (July 1, 2025 estimate)
