So, you're thinking about starting an HVAC business in the Golden State. That's a big move, and honestly, it’s one of the best ones you can make. I’ve started a few service businesses myself, and I can tell you that California is a different beast. It’s got the heat, it’s got the people, and it’s got the money. But it also has a lot of rules that can trip you up if you aren't looking.
I'm gonna walk you through everything you need to know to get your van on the road. We aren't gonna use big corporate talk here. This is just plain English from someone who wants to see you win. We’ll talk about the costs, the licenses, and how to actually get people to call you.
California is a high-risk state when it comes to legal stuff. You're gonna be signing contracts with homeowners for thousands of dollars. Before you start using a complex service agreement, you really should talk to a licensed attorney. It’s one of those things where spending a little money on a licensed professional now saves you a massive headache later.
What makes starting a HVAC business in California different
California isn't like other states where you just buy a set of gauges and a ladder and start charging people. The first thing you’ll notice is the weather. It’s not just "hot." You’ve got the dry heat of the Central Valley where ACs run 24/7 in July. Then you’ve got the humid coastal air in San Diego or the Bay Area that eats through equipment with salt and moisture.
The people here also expect a lot. California homeowners are usually pretty tech-savvy and very worried about energy bills. They don't just want their house cool; they want it done with the most efficient heat pump on the market. You aren't just a repairman here; you’re an energy consultant.
The biggest difference, though, is the paperwork. California has some of the strictest building codes in the country. They care about the environment, and they care about worker safety. This means you’ll spend a bit more time on permits and inspections than a guy in Texas or Florida might. It feels like a lot of red tape at first, but it actually helps you because it keeps the "trunk slammers" out of the market.
What it costs to start
Let’s talk about the money part because that’s what everyone worries about. You don't need a million dollars, but you do need a "war chest." To start an LLC in California, the state charges a $70 filing fee for your Articles of Organization (source). You do this through the BizFile Online website. It usually takes about 5 to 10 business days if you do it online.
Then there is the "California Tax." Every LLC in California has to pay a minimum franchise tax of $800 every single year. It doesn't matter if you made zero dollars or a million dollars; the state wants that $800. The good news is that for LLCs formed recently, the state has been waiving that first year’s fee. You’ll still want to keep that money in the bank just in case, though.
Insurance is another big one. For a typical HVAC setup, you’re looking at General Liability insurance costing between $50 and $170 a month. You also have to think about your tools and your van. A decent used van might run you $15,000, and a full set of pro tools can easily hit $5,000. Don't forget the $20 fee for your Statement of Information, which is due 90 days after you start and then every two years after that.
California-specific regulations you need to know
California loves its regulations, and you need to know them so you don't get fined. The biggest one is the CSLB, which is the Contractors State License Board. You cannot legally do HVAC jobs over $500 in California without a state contractor's license. If you get caught working without one, the fines are brutal, and you might lose the right to ever get licensed.
Another thing to watch is how you hire people. California is very strict about who is an employee and who is a contractor. You can’t just hire a "1099 helper" to carry your tools. Most workers in California must be W-2 employees. This means you’ll need workers' comp insurance the second you hire your first person. It’s an extra cost, but it protects you if someone falls off a ladder.
Lastly, you have to deal with sales tax. In California, you generally don't charge sales tax on your labor. If you spend four hours fixing a unit, that labor is usually tax-free. But, if you sell the customer a new capacitor or a whole new furnace, you have to charge sales tax on those parts. It gets complicated when the labor creates a "physical product," so keep your invoices very clear.
How much HVAC pays in California, by city
The money you can make varies a lot depending on where your van is parked. In Los Angeles, the demand is huge, but the traffic is a nightmare. An owner-operator in LA can easily clear $150,000 a year if they stay busy. The competition is stiff, but there are millions of old units that need constant love.
San Francisco and the surrounding Bay Area have the highest prices. You can charge a premium there because the cost of living is so high. It’s not uncommon to see service calls start at $150 just to show up. However, your rent and gas will be much higher there, so you have to manage your overhead carefully.
If you go to Fresno or Sacramento, the summers are where you make your "nut." When it hits 110 degrees, people will pay almost anything to get their AC back on. In these cities, you might work 14-hour days all summer and then relax a bit in the spring. San Diego is more steady year-round because people use their systems for both cooling and dehumidifying throughout the year.
Navigating Title 24 and HERS testing
This is the technical stuff that really separates the pros from the amateurs in California. Title 24 is the state's energy code. It says that when you install a new HVAC system, it has to meet certain efficiency standards. You can't just slap a unit in and walk away. You have to make sure the ductwork is sealed tight and the unit is tuned perfectly.
Most of the time, this requires a HERS test. HERS stands for Home Energy Rating System. A third-party rater has to come out and verify that your installation actually does what the paperwork says it does. They check for duct leaks and make sure the refrigerant charge is correct. It adds a few hundred dollars to the job cost, but it's mandatory in most California climate zones.
You should build the cost of the HERS test and the permits right into your quotes. Don't try to hide it or skip it. If a building inspector catches an unpermitted install, they can make you tear it all out. It’s better to explain to the customer that you do things "by the book" to protect their home's value.
Licensing and permits
To get your C-20 HVAC license, you need to show the state that you have four years of journey-level experience. You’ll have to pass two exams: one on the trade itself and one on law and business. It’s not an easy test, so you’ll want to get a study guide. You also have to get a contractor’s bond, which is currently set at $25,000 in California.
On top of the state license, you’ll need a local business license for the city where you’re based. If you work in multiple cities, some might want you to get a "permit" to work there too. It feels like everyone wants a piece of your paycheck, but it’s just part of doing business. Keep a folder in your van with all your paperwork so you can show it if anyone asks.
Don't forget the EPA 608 certification. This is a federal requirement, not just a California one. You can't buy or handle refrigerant without it. Most guys get this while they’re still in school or working for someone else. If you don't have it yet, that should be your very first step before you even buy a van.
Getting your first 10 customers
The first ten customers are the hardest ones to get. Since you’re starting fresh, you won't have a big stack of five-star reviews yet. Start with "Sweat Equity." This means walking the neighborhoods where you want to work and putting door hangers on houses with old, noisy AC units. It’s old school, but it works because people see your face.
Nextdoor is a goldmine for HVAC guys in California. People are always asking for "a local guy who won't rip me off." Set up a profile and keep an eye on the boards. When someone asks for help, reply quickly and be honest. Don't try to sell them a whole new system over the phone; just offer to come take a look.
Google Local Services Ads are the best paid way to get leads. These are the "Google Guaranteed" ads at the very top of the search results. You only pay when someone actually calls you. It takes a bit of time to get verified because Google checks your license and insurance, but once you’re in, the leads are usually very high quality.
Seasonal calendar for California
In California, your bank account will follow the sun. May through October is your "money season." This is when the AC calls come in fast and furious. You’ll be doing a lot of "no-cool" calls and emergency replacements. During these months, you should be putting away at least 30% of your income to cover the slower times.
November through February is heating season. While California isn't the North Pole, it still gets cold, especially at night. You’ll be busy fixing furnaces and heat pumps. This is also a great time to offer indoor air quality products like better filters or UV lights since people are spending more time inside with the windows shut.
March, April, and October are your "shoulder months." These are the times when the weather is nice and nobody is thinking about their HVAC. This is when you run your maintenance specials. Offer a "Spring Tune-Up" for a low flat rate. The goal isn't to make a ton of money on the tune-up; it’s to find the parts that are about to break before they fail in July.
Frequently asked questions
Q? Do I really need an LLC to start my HVAC business in California? You don't legally have to, but you really should. An LLC protects your personal stuff, like your house and your car, if your business gets sued. Since HVAC involves fire, high voltage, and heavy equipment, there’s always a risk. Paying the $70 filing fee and the $800 annual tax is a small price to pay for that kind of peace of mind.
Q? What is the minimum franchise tax, and do I have to pay it the first year? The minimum franchise tax is $800 that California charges every LLC just for existing. For several years now, California has waived this fee for the first year of a new LLC. So, you likely won't pay it when you first sign up. But starting in year two, you’ll need to send that $800 to the Franchise Tax Board every single year.
Q? Can I do HVAC work in California without a C-20 license? Only if the total cost of the job, including parts and labor, is less than $500. In the HVAC world, $500 doesn't go very far. A simple motor replacement or a refrigerant recharge can easily go over that. If you want to run a real business and do installs or major repairs, you absolutely need that C-20 license from the state.
Q? Do I have to charge sales tax on my HVAC services? In California, you generally don't charge sales tax on the labor you provide to fix something. However, you do have to charge sales tax on any parts or equipment you sell to the customer. So, your invoice should show a line for labor (no tax) and a line for parts (with tax). It’s important to keep these separate so your bookkeeping stays clean.
Q? What kind of insurance is required for a California HVAC business? The state doesn't technically require General Liability insurance to get your license, but you’d be crazy to work without it. Most homeowners and all commercial clients will ask for a certificate of insurance before they let you in. If you have any employees, California does require you to have Workers' Compensation insurance, and there are no exceptions for that.
Q? How much can I charge for a service call in California? It depends on your city, but most guys charge between $89 and $150 just to show up and diagnose the problem. If you’re in a high-cost area like San Francisco or West LA, you can be on the higher end. Just make sure you’re clear with the customer about whether that fee goes toward the final repair cost or if it’s an extra charge.
Q? What is a contractor's bond, and why do I need one? California requires all licensed contractors to have a $25,000 bond. This isn't insurance for you; it’s protection for your customers. If you take a deposit and never finish the job, or if you do work that violates the building code and refuse to fix it, the customer can file a claim against your bond to get their money back.
Q? Should I hire an attorney to help me start my business? While you can file the basic LLC paperwork yourself, California is a very litigious state with complex labor laws. It is a very smart move to have a licensed attorney look over your service contracts and employment agreements. A licensed lawyer can make sure your "fine print" actually protects you if a customer tries to sue you over a system failure or a property damage claim.
Starting an HVAC business is a lot of work, but it’s one of the few jobs left where you can really build something with your own two hands. Just take it one step at a time. Get your license, set up your LLC, and start treated your customers like family. If you do that, you’ll never run out of work in California.
