Before you hire

Checking an HVAC company in the Sioux Falls area

HVAC licenses in South Dakota

There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.

Who licenses: Local governments

Local rules: The state Department of Labor and Regulation lists licensing boards only for electrical and plumbing (no HVAC or mechanical board), so HVAC is licensed locally; for example, Sioux Falls requires a Mechanical Contractor's License (with a Master Mechanic exam) for all HVAC work within city limits and a separate Refrigeration Contractor license, and we did not read the state statutes to confirm there is no other statewide rule.

Check your city or county building department's list of licensed contractors (Sioux Falls publishes one at https://www.siouxfalls.gov/business-permits/currently-licensed-contractors) and ask for the local license number.

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 South Dakota’s own sources, so treat this as a starting point and check with the agency.

Sources: dlr.sd.gov, siouxfalls.gov, siouxfalls.gov. Checked October 2026 from official sources. This is not legal advice.

HVAC licenses in Iowa

HVAC contractors are licensed by the state.

Who licenses: Iowa Plumbing and Mechanical Systems Board (PMSB), Iowa Department of Inspections, Appeals, and Licensing (DIAL)

License types: Contractor License, Master License, Journey Level License, Apprentice License, Service Technician HVAC Specialty License.

Companies: Under Iowa Code 105.10, a person may not operate as a contractor or install or repair plumbing, mechanical, HVAC, refrigeration, sheet metal or hydronic systems without a license. The Board's contractor license is required of anyone providing those services on a contractual basis. DIAL lists these requirements for it: a permanent place of business, a valid unemployment insurance number, $500,000 minimum public liability insurance, a $5,000 minimum surety bond, and at least one active master licensee for each discipline in which the company works. Section 105.11 exempts an owner doing work on their own principal residence if it is an existing single-family-sized dwelling (or farm property) and not commercial or industrial work.

Local rules: Iowa Code 105.17 says the state licensing provisions supersede and preempt the plumbing, mechanical, HVAC-refrigeration, sheet metal and hydronic licensing provisions of all governmental subdivisions, so cities such as Des Moines cannot add their own HVAC licenses. Cities and counties may still charge permit and inspection fees (105.17(2)), so a local permit may still be required.

Check a license: ia-plb.my.site.com

Search the contractor on the state professional license search and confirm an active contractor license covering HVAC or mechanical work, and ask who the master of record is for the job.

Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

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 Sioux Falls winter

Heating season is the long one in Sioux Falls, 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.

Furnace maintenance: a fall checklist for safe heatA gas furnace burns fuel inside your home, so fall maintenance is about safety as much as comfort. Here is what to do yourself and what the yearly professional inspection should cover.Furnace not working? What to check firstA furnace that will not start is often stopped by a safety switch doing its job. Here is how to find which one – and when to leave the house instead.How to prevent frozen pipes: before and during a freezeWater expands as it freezes, and that pressure can split a pipe. A few steps before winter and during cold snaps prevent most frozen pipes, and the right response limits damage when one freezes anyway.Carbon monoxide and your furnace: alarms, warning signs and what to doCarbon monoxide is a poisonous gas you cannot see or smell. Fuel-burning furnaces, boilers and water heaters can produce it when something goes wrong. Alarms and yearly inspections are the main defenses.Heat pump maintenance: year-round care in both seasonsA heat pump heats in winter and cools in summer, so it runs more of the year than an AC or a furnace alone. Simple upkeep matters in every season, especially keeping the outdoor unit clear of snow and ice.Furnace smells like burning? What the smell means and what to doMost furnaces give off a faint smell the first time they run each fall. A few smells mean turn the system off now, and one means get out of the house. Here is how to tell them apart.
