How Much Does HVAC Installation Cost in Ohio in 2026

The Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com) puts its HVAC conversion to electrification at $19,484, a U.S. average. Ohio’s HVAC mechanics out-earned the nation in May 2025: $31.73 an hour on average against $31.14. Ohio’s state HVAC license covers commercial projects; for houses, any contractor licensing is up to your county or city.

The one installed price we can source

Zonda Media’s report compares 28 projects across 119 U.S. markets. Its “HVAC Conversion | Electrification” project averaged a job cost of $19,484 nationally in 2025, with a resale value of $14,053, so 72% of the cost was recouped. We print the national figure because the report’s page for Ohio’s region could not be retrieved. Our captures of the report carry no scope for that project (which system comes out, what goes in), so it is a benchmark for the report’s defined job, not a quote for swapping your furnace and AC.

Wages are the other sourced input. The Bureau of Labor Statistics estimated 14,150 heating, air conditioning and refrigeration mechanics and installers on Ohio payrolls in May 2025. Their mean pay was $66,000 a year and their median $30.06 an hour; nationally the median was $29.33. These are employee wages, self-employed installers excluded, and they measure one input of your bid, not the bid.

Ohio’s HVAC license is commercial; houses are regulated locally

Chapter 4740 of the Revised Code lets the Ohio Construction Industry Licensing Board license five trades, HVAC among them (R.C. 4740.01(A)). Its “contractor” works on a “construction project,” and 4740.01(F) leaves a “residential building” out of that term. Under R.C. 3781.06(C)(9) a residential building is a one-, two- or three-family dwelling house plus any accessory structure incidental to it (model homes included; industrialized units, manufactured homes and mobile homes excluded). The board says so directly: it “regulates commercial contractors,” while “[a]ll local building and health departments regulate residential contractors,” and state law lets those departments “require the State commercial license for their residential contractors.”

The local rule comes from two statutes. A board of county commissioners may license HVAC contractors who are not required to hold a Chapter 4740 license, with its rules reaching unincorporated areas and any city that contracts for county enforcement (R.C. 3781.102(B)); a municipal corporation may license specialty contractors in the same position (R.C. 715.27(A)(3)). Either may accept the state license for work on one- to three-family dwellings. Neither may make a state licensee sit an exam, but both may charge a registration fee, and a municipality may also ask for a bond, proof of insurance, workers’ compensation compliance and registration with its tax department (3781.102(C)-(D); 715.27(B)-(C)).

Approval for a furnace, AC or heat pump swap

Ohio’s residential code is the Residential Code of Ohio (Ohio Adm. Code 4101:8), built on the 2018 International Residential Code; its administration rule, 4101:8-1-01, has been in effect since July 1, 2019. Section 105.1 requires anyone who intends to “install, enlarge, alter, repair, remove, convert or replace” a mechanical system to get approval from a certified residential building department first.

Section 102.10 lists ten mechanical exemptions. Among them: portable heating, cooling and ventilation units; replacing a part “that does not alter approval of equipment or make such equipment unsafe”; and self-contained refrigeration systems holding ten pounds of refrigerant or less or driven by motors of one horsepower or less. Replacing a whole furnace or condenser is not on that list.

Two limits decide whether anyone reviews your job. Under 101.5, where no certified residential department has jurisdiction, the owner does not have to submit documents, seek approvals or request inspections. And under R.C. 3781.10(E), a department certified for new houses enforces the code on repair and alteration of existing houses only if it also holds that certification; it has jurisdiction only over what it is certified for.

The federal credits stopped at the end of 2025

Public Law 119-21, enacted July 4, 2025, wrote end dates into two federal credits. Subsection (i) of 26 U.S.C. § 25C, the energy efficient home improvement credit, switches it off for property placed in service after December 31, 2025. Subsection (h) of § 25D, the residential clean energy credit, switches it off for expenditures made after that same date, and § 25D(e)(8)(A) treats an expenditure as made once the original installation is completed (new construction has its own timing rule). Equipment installed in Ohio in 2026 therefore earns neither credit. Utility rebates are set by each utility; check its current program page before counting one in your budget.

Frequently asked questions

Does the person replacing my furnace need an Ohio state license?

Not for a one-, two- or three-family house under Chapter 4740, whose license attaches to construction projects that exclude residential buildings. Your county or city may still license HVAC contractors, and local departments may require the state license for residential work.

The furnace quit on a January night. Can it be replaced before approval?

Yes. For equipment replacements and repairs that must be done in an emergency, section 102.10.1 of the residential code says “an application for approval shall be submitted within the next working business day to the building official.”

A salesperson says my new heat pump still gets a federal tax credit. True?

Not if it goes in during 2026: § 25C stopped covering property placed in service after December 31, 2025.

Is there anywhere in Ohio a replacement needs no approval?

Yes: where no certified residential building department has jurisdiction, section 101.5 of the code drops the approval and inspection steps. Section 101.2 still requires equipment to be installed in conformity with the board’s rules.
