Before you hire
Checking an HVAC company in the Madison area
HVAC licenses in Wisconsin
HVAC contractors are licensed by the state.
Who licenses: Wisconsin Department of Safety and Professional Services (DSPS)
License types: HVAC Contractor.
Companies: DSPS issues an 'HVAC Contractor' credential, an organization (business) credential regulated under Wisconsin Administrative Code chapter SPS 305; We could not read the rule text or statute to confirm exactly who is required to hold it.
Local rules: We did not verify city or county rules, and could not confirm the statutory basis or any related qualifier or tradesperson credentials, so confidence is medium.
Check a license: license.wi.gov
Search the company on the state LicensE portal (license.wi.gov) to confirm it holds a current HVAC Contractor credential.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from Wisconsin’s own sources, so treat this as a starting point and check with the agency.
Sources: dsps.wi.gov. Checked October 2026 from official sources. This is not legal advice.
Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Getting through a Madison winter
Heating season is the long one in Madison, so the furnace, boiler or heat pump does most of the work. Start with these before the first cold snap – and keep carbon monoxide alarms working.
