Start with licensing and insurance
Every legitimate HVAC contractor operating in Columbus should hold an active Ohio Construction Industry Licensing Board (OCILB) HVAC contractor license. Ask for the license number and verify it directly on the Ohio Department of Commerce's license lookup rather than taking a company's word for it - confirm the license is current and has no unresolved disciplinary history.
Technicians who handle refrigerant also need EPA Section 608 certification, which is separate from the OCILB business license. Ask specifically whether the technician coming to your home holds this certification, not just whether the company is licensed.
Confirm general liability insurance and workers' compensation coverage as well. A contractor who cannot produce proof of insurance is a liability if a technician is injured on your property or if the work damages your home.
Know your permit jurisdiction before you get quotes
Columbus itself permits mechanical work through the Department of Building and Zoning Services at 111 N Front St, and a furnace or AC changeout inside city limits needs a permit and a final inspection to close it out.
Several inner suburbs - Bexley, Upper Arlington, Worthington, and Grandview Heights among them - run their own building departments and permit HVAC work separately from the city, so confirm which office actually covers your address before assuming.
If you live in an unincorporated Franklin County township, permitting runs through the Franklin County Building Department instead. Ask any contractor bidding your job which jurisdiction they will file with, and get the permit number in writing once work is scheduled - a contractor unwilling to pull a permit is not one to hire.
Get and compare real written quotes
Get at least two, ideally three, written quotes for any job beyond a simple repair. Columbus HVAC pricing varies meaningfully by contractor, and the spread is often driven by brand tier, ductwork condition assessment, and whether a company includes permit fees and rebate paperwork in the quoted price.
Insist on a Manual J load calculation for full system replacements rather than a same-tonnage swap, particularly in older German Village, Victorian Village, or Clintonville homes where past renovations may have changed the actual heating and cooling load.
Read each quote for equipment make, model, tonnage or BTU rating, AFUE or SEER2 efficiency rating, refrigerant type, permit inclusion, and warranty terms for both parts and labor - a low number that omits the permit or a load calculation is not actually the cheaper bid once it is done correctly.
For a faster way to gather comparable quotes, describe your job and ZIP code at Homeowner Henry's Columbus matching page and up to three vetted, licensed local contractors will follow up directly.
Red flags and final checks before you sign
Be wary of a contractor who quotes a full system replacement over the phone without an in-person inspection, who pressures same-day signing with a large discount, or who cannot name the permit office covering your address.
Ask about AEP Ohio and Columbia Gas of Ohio rebate eligibility for the specific equipment being quoted, and confirm in writing who is responsible for filing the paperwork.
Before signing, confirm in writing: OCILB license number, permit number and jurisdiction, equipment specifications, rebate handling, and separate parts and labor warranty terms.

Common questions
How do I verify an HVAC contractor's license in Columbus, Ohio?
Look up the contractor's OCILB HVAC license number through the Ohio Department of Commerce's license lookup tool, and confirm it is active with no unresolved disciplinary history before hiring.
How many quotes should I get for HVAC work in Columbus?
At least two, ideally three, written quotes for any job beyond a minor repair. Pricing varies meaningfully across Columbus contractors, and comparing itemized quotes side by side reveals which bids actually include permits, load calculations, and rebate paperwork.
Who pulls the HVAC permit in Columbus - me or the contractor?
The contractor should pull the mechanical permit as part of the job, whether through the Columbus Department of Building and Zoning Services, a self-permitting suburb, or the Franklin County Building Department for township addresses. Get the permit number in writing before work begins.
What questions should I ask before hiring an HVAC contractor in Columbus?
Ask for the OCILB license number, proof of insurance, whether they will perform a Manual J load calculation, which permit office they will file with, what AEP Ohio or Columbia Gas of Ohio rebates apply, and what the parts and labor warranty terms are - all in writing.
Is it worth using a matching service instead of calling contractors directly?
It can save time, since Homeowner Henry pre-screens for active licensing and insurance and sends up to three quotes from vetted Columbus contractors rather than requiring you to research and call each company individually.
