Call Now — (844) 582-179524/7 call line · call to check availability in Honolulu
AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Water dripping from vent or air handler
Water from a ceiling vent · pooling near the indoor air handler · drain pan overflowing. Typical causes of condensate overflow include a clogged or dislodged drain line, a cracked or corroded drain pan, a failed condensate pump, and a dirty filter that lets the coil freeze (ACCA). Turn the thermostat off to limit water damage and call a technician.

HVAC in Honolulu, HI: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Hawaii licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Daniel K. Inouye International Airport (KHNL, formerly Honolulu Intl) is the NOAA reference station for Oahu. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00022521), Honolulu records an annual mean temperature of 78.0°F, approximately 4,767.1 annual cooling degree days against zero heating degree days, 16.41 inches of annual precipitation, and no measurable snowfall. Honolulu’s tropical Zone 1A climate has no heating demand whatsoever under the standard 65°F degree-day baseline.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Urban Honolulu CDP, Hawaii) report 136,228 occupied housing units with a median year built of 1973. Heating-fuel distribution: 44.97% of occupied units report NO fuel used for heating (61,258 units) — because in Honolulu’s tropical climate central heating is simply unnecessary. 46.42% use electricity (63,239 units, primarily for occasional warming of bathrooms and unusual cool nights), only 4.79% use utility gas (6,521 units), and a notable 2.78% (3,792 units) use solar energy — an unusually high solar-heating share reflecting Hawaii’s abundant sun plus high electricity costs driving rooftop solar adoption.
Hawaii DCCA
Every HVAC contractor in Honolulu must hold a current C-52 Ventilating and Air Conditioning Contractor license from the Hawaii Department of Commerce and Consumer Affairs (DCCA) Professional and Vocational Licensing Division Contractors License Board. The C-52 classification covers ventilating and air conditioning contracting statewide. Verifying a contractor’s active C-52 license via DCCA’s online lookup before authorizing work is the baseline due-diligence step. Permit fees for residential mechanical work are set by the City and County of Honolulu Department of Planning and Permitting (DPP) under the Revised Ordinances of Honolulu; contact DPP Building Division at (808) 768-8242 for the current fee schedule. Note: Honolulu is a Census Designated Place within the consolidated City and County of Honolulu — permitting is handled at the county level.
Hawaii Energy
Hawaii’s ratepayer-funded efficiency program, Hawaii Energy, administers HVAC rebates for Hawaiian Electric (HECO) customers on Oahu (plus Maui County and Hawaii Island). Current instant rebate amounts verbatim: central air conditioner retrofit: $1,250 instant rebate; air conditioner tune-up: $75; window air conditioner: up to $45 ($25 standard / $45 dual inverter); mini-split VRF air conditioner: up to $550 per unit; whole house fan: $100; solar attic fan: $75.
Honolulu’s coastal Pacific location subjects outdoor HVAC equipment to continuous salt-laden trade winds. Meanwhile, Honolulu’s trade winds provide natural ventilation that many older homes use instead of mechanical cooling — which explains both the 45% no-fuel share and the relatively modest penetration of whole-house central AC compared to mainland tropical cities like Miami.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
