How to start a furnace repair business in St. Louis, MO
This is not legal, tax, or insurance advice. Read the official pages linked here. Partner offers are optional and labeled.
Heating carries the winter. Basement furnaces and older boilers are a different visit from a newer closet system. Split repair from replacement. Name the neighborhoods where the equipment is actually in a basement. In St. Louis, the housing decides the visit: brick houses and basements in the city and close-in suburbs, with a separate newer stock in St. Charles. The weather on the truck is humid summers, cold winters, ice, tornado and hail risk, and clay that moves with moisture. Central West End, Soulard, and Clayton are worth naming only when they are real stops. Kirkwood and St. Charles are a different drive until you can reach them the same day. City of St. Louis permits is the local counter to ask when the job needs a permit or a city registration. This page names that office. It does not invent a fee. The Illinois side of the metro is a different state license. This page is about the Missouri side: the city, Clayton, Kirkwood, and St. Charles. Do not imply one license covers both banks of the river. City customers want a crew that can work an old brick house. Suburban customers want a crew that shows up inside a normal window. Those are different promises.

The Missouri guide has the filing office. This page is the local version: what the first jobs are, which permit counter to call, and how to price a day here.
Some boxes are labeled Partner. ServiceBase has not joined those programs. The links go to each company's own homepage, not a tracking link. If a program later approves us, the address will change and we may earn a commission. You can file, insure, and bank anywhere. Official government links are not partner links. Nothing on this page is a discount code.

Keep the checklist on your account
The guide stays public. An account saves your state, city, and trade, and lets you mark each filing as you go. The advertising credit is reserved when you register. It can be spent after the free website is live.
The mechanical or HVAC license is often held by a person who qualifies the company. A sole proprietorship works when that person is you. An LLC works when the board lets the company hold the registration with you as qualifier. Read the mechanical section before you file. An LLC does not let an unlicensed owner pull a permit or buy refrigerant. This page is not legal advice.
We do not have a filing fee for Missouri that we are willing to print. Use the SBA lookup, choose Missouri, and read the fee on the state office's own page. Sole proprietors who operate under their own name often skip this filing. Confirm that on the same site.
If your customers are in St. Louis, the registered-agent address still has to satisfy Missouri. Read the filing office's rule. A neighbor's kitchen table is not always an acceptable address.
An employer identification number is the business tax ID. The IRS issues it online at no charge and says you never have to pay a company to get one. If you form an LLC, file with the state first. The IRS says an EIN application can stall when the state filing is not done. A sole proprietor can often start with a Social Security number and get an EIN when a bank or a hire requires it.
Apply on the IRS page if you want the number yourself. LegalZoom, the partner beside this step, can request it while they form the company. That service is optional. The IRS fee is still zero either way.
Read the mechanical or HVAC board for the license and who may pull a permit. Ask the city whether a furnace change-out needs one. Say whether boilers are in or out. Refrigerant handling is a separate credential when the job leaves the furnace.
We could not confirm one statewide contractor-board address. Check the city or county, and any state board that names your specific trade.
City of St. Louis permits is the local counter for work in St. Louis. We are naming that office, not linking a fee schedule we have not read. Call them or open the city's own site and ask what a new furnace repair has to register before the first job in Soulard.
The Missouri guide repeats the board link and tells you what we could not verify. Read it before you pay a filing service.
05Insure the work
General liability that understands heating equipment. Tell the insurer you open furnaces and, if it is true, that you replace them. A carbon-monoxide claim and a water leak from a coil are the losses to describe. Commercial auto for the van. Workers' compensation before a helper is in an attic or a basement. A property manager will ask for the certificate and the license number together.
Workers' compensation is a state program. Before anyone works with you, including a friend, ask an insurer and the state labor office whether you must carry it. This guide does not quote a headcount, because those rules differ and the state page is the source. The SBA page describes the common policies. It does not sell them. Buy the policy before you work in a house in St. Louis.
No-heat calls pay in smaller checks than a full system, and a replacement pays in a large one. Both belong in a business account, or the big jobs will hide whether the repairs pay the truck. Set tax money aside the day a change-out clears. Parts-house bills should not land on a personal card you sort out in April.
The bank will usually ask for your ID, the EIN or your Social Security number, and the formation papers if you filed an LLC. A checking account and a habit of setting tax money aside are enough at the start.
07Price a day in St. Louis
Treat these as typical planning estimates, not a quote. A diagnosis plus a common part, an ignitor or a flame sensor, is often discussed as a few hundred dollars. A heat exchanger, a blower motor, or a full furnace is a different visit and should not share the number. Write three prices from your own hours: the diagnostic visit, the repair you can finish with stocked parts, and the replacement you will not price until you have seen the equipment.
Attic furnaces, basement furnaces, and boilers do not take the same hour. A price copied from a one-story ranch will miss on a tight closet system. Adjust after ten real no-heat calls. Say on the page that the estimate is a starting point until someone has opened the cabinet.

08Open the profile, the reviews, and the site
Claim the Google Business Profile for St. Louis, MO. Set hours you answer. The service area should list Central West End, Soulard, and Clayton if those are real stops, and it should leave off towns you will not drive.
Ask for a review after a clean job, and ask them to mention the neighborhood and the task. A review that says the work and Kirkwood helps the next search. A review that says 'great service' does not.
Open the Google Business Profile before the heating season, with the license number and a service area made of towns you can reach when the house is cold. Photos of furnaces you have actually repaired beat a stock cabinet. The website leads with no heat, splits repair from replacement, and says whether you service boilers. The form asks for the symptom, the fuel if they know it, and whether anyone in the house is at risk from the cold. ServiceBase publishes that page and keeps the requests. It does not diagnose the furnace.
When the name and the phone are real, create the free furnace repair site with St. Louis already filled in. Quote requests land in your list. The site does not replace City of St. Louis permits.

Can I publish a furnace repair site before the LLC is approved?
You can draft it. Put it in public under the name you will actually use, with the phone you answer. If the state requires the license before you advertise the work, wait. The free ServiceBase site does not file the company. Signup can open with furnace repair and St. Louis filled in so you are not retyping them.
