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.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Possible causes include a failing fan motor, a loose blower wheel, or worn compressor bearings. Turn the system off at the thermostat and call a technician.

About 22% of households heat with natural gas vs. 76% electric. The Alabama grid averages $0.16/kWh.

HVAC in Huntsville, AL: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Alabama licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Huntsville sits inside the documented Dixie Alley tornado corridor; ask your installer how the outdoor unit will be anchored to its pad, and follow severe-weather alerts from NWS Huntsville. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (Huntsville International Airport, KHSV / USW00003856), Huntsville records approximately 2,831 annual heating degree days against 2,107 cooling degree days, an annual precipitation normal of 54.29 inches, and an annual snowfall normal of only 2.4 inches. The city averages 61.6 days per year above 90°F and 56 days below freezing. The roughly 1.3:1 HDD-to-CDD ratio places Huntsville firmly in the dual-load category, and the 54-inch precipitation total drives substantial summer latent (humidity) loads — variable-speed dehumidification capability is a primary specification, not a luxury.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040, B25003, B25077 and B25035) report 94,058 occupied housing units in Huntsville with a median year built of 1984 — meaningfully newer than the 1974 median that prevails in older Alabama industrial cities. Heating-fuel distribution: 75.8% electricity (71,266 units), 22.2% utility natural gas (20,912 units), and 1,037 on bottled/tank/LP gas. Owner-occupancy is 58.1% and the median home value is $263,100, reflecting federal-civilian and contractor incomes. The dominant-electric profile is a TVA-territory hallmark.
TVA EnergyRight
Huntsville's electric service is provided not by Alabama Power but by Huntsville Utilities, a municipally owned utility that purchases wholesale power from the Tennessee Valley Authority and resells it to retail customers — structurally identical to Knoxville's KUB and Chattanooga's EPB. Residential HVAC rebates flow through the TVA EnergyRight framework, with Huntsville Utilities providing the local-utility match. Per the EnergyRight heat pump page, rebate-eligible upgrades must be completed by a member of the TVA Quality Contractor Network (QCN), and the published heat pump rebate is $500 for 15–16.99 SEER2 or $800 for 17 SEER2 or higher. Alabama’s federally funded Home Energy Rebates (HEEHR and HOMES) are being developed by the Alabama Department of Economic and Community Affairs (ADECA). As of September 2026, ADECA says the program “is under development” and the date households can access rebates “has not been determined.” ADECA’s program page explains how to sign up for update notifications.
ENERGY STAR (EPA)
The federal Energy Efficient Home Improvement Credit (IRS Section 25C) was terminated for property placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21, signed July 4, 2025). HVAC equipment installed in 2026 does not qualify for the federal credit. Huntsville homeowners whose equipment was installed by Dec 31, 2025 may still claim the credit on their 2025 tax return. For 2026 installations, check current state and utility rebate programs — start with the ENERGY STAR Rebate Finder for current state-level program status.
Alabama issues HVAC licensing through the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR). For Huntsville homeowners, the practical wrinkle is that HACR issues two separate license classes — HVAC and Refrigeration — and the scope of work permitted differs. A pure HVAC license covers central air, heat pumps, and gas-furnace work, but commercial refrigeration and certain ice-machine or walk-in cooler work falls under the Refrigeration class. Combination licensees pay $350 in exam fees (versus $175 per single class) to cover both scopes. Active HVAC contractors are required to post a $20,000 performance (surety) bond with the Board, and renewal requires 4 hours of continuing education annually. Anyone handling refrigerant must additionally hold a current EPA Section 608 certification under federal law — this is especially relevant in Huntsville because the federal AIM Act phasedown is accelerating R-410A retirement and pushing the market toward R-454B and R-32 equipment, and Section 608 governs all such refrigerant handling. Local permits are pulled through the City of Huntsville Inspection Services Department.
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).
