Kentucky HVAC leads

How Kentucky homes are heated

Electric heat holds a narrow lead in Kentucky. The Census Bureau’s table B25117 for 2020-2024 counts 613,961 of the state’s 1,239,908 owner-occupied homes (49.5%) heating mainly with electricity and 481,914 (38.9%) with utility gas. Propane, at 7.8%, is the only other fuel above 3%.

When renters are added, table B25040 (2020-2024 ACS) puts electricity at 54.9% of 1,814,469 occupied homes and utility gas at 35.2%. The fuel mix tells an HVAC buyer which trade skills a Kentucky replacement job calls for: gas line and venting work on a furnace swap, or refrigerant and electrical work on a heat pump. It is a description of housing, not of where requests originate.

Kentucky HVAC contractor licensing

Kentucky licenses heating, ventilation and air conditioning work at the state level through the Department of Housing, Buildings and Construction, under KRS 198B.650 to 198B.689. KRS 198B.656 sets three tiers and bars anyone from practicing HVAC contracting without meeting the chapter’s requirements:

• Master HVAC contractor: licensed to advertise and practice HVAC contracting, pull the permits and take primary responsibility for the work.
• Journeyman HVAC mechanic: licensed to do HVAC work under the supervision and responsibility of a master contractor.
• Apprentice HVAC mechanic: holds a certificate and assists a master or journeyman while learning the trade.

The definitions in KRS 198B.650 cover installation, maintenance, alteration and repair of heating, cooling, ventilation and hydronic systems and burner service, but not duct cleaning. They also define a "major repair" as the complete replacement of a furnace, condensing unit, heat pump, fan coil unit, chiller or heating boiler.

Two more sections matter for a buyer working with Kentucky contractors. KRS 198B.6671 requires a permit before anyone installs an initial HVAC system, the first system in a building, while window air conditioners and space heaters need no permit. KRS 198B.668 requires (as of October 8, 2026) at least $500,000 of general liability and $300,000 of property damage insurance to practice. Federal refrigerant certification under EPA Section 608 applies on top of the state license.

Kentucky home energy rebate status

The Energy and Environment Cabinet’s Office of Energy Policy runs the Kentucky Home Energy Rebates program, created under the federal Inflation Reduction Act. The program page lists HVAC system upgrades among the eligible improvements, alongside insulation, air sealing and electrical panel or wiring work.

Status as of October 8, 2026: the page states that the program is not yet accepting rebate applications, and that the U.S. Department of Energy must approve Kentucky’s application and plans before it opens. The page gives no rebate amounts.

Reading the Kentucky numbers as a buyer

Taken together, the Kentucky figures point to a few planning questions:

• Fuel splits by county. Utility gas heats over two thirds of owner homes in Jefferson and Daviess, while Madison and Hardin are about three quarters and two thirds electric, in the ACS county data. The equipment a crew is set up for may shape which counties it covers.
• Winter is the bigger load. At 4,275 heating degree days in 2025 against 1,394 cooling degree days in the NCEI series, heating equipment works the longer season, while summer cooling ran above its 1991-2020 average.
• Licensed masters carry the permit. Under KRS 198B.656 the master HVAC contractor is the license holder entitled to obtain permits for HVAC work and is primarily responsible for that work.

Each point rests on official housing, weather or statute records. None of them is a measure of request counts in any county.
