Ever wonder what it takes to start your own HVAC side hustle? Here is a guide just for you!

1. Start With Work That Doesn’t Require a Contractor License

Every state is different, but almost all of them allow you to do basic non-refrigerant work without a full HVAC contractor license.

You can safely do:

  • Filter changes

  • Thermostat installs

  • Cleaning coils

  • Tune-ups

  • Capacitors, contactors, relays

  • Replacing blower motors

  • Duct repairs or sealing

  • Drain line cleanouts

You need an EPA 608 certification to handle refrigerant, and most states require a contractor license for full installs.

2. Make It Clear You’re Doing “Side Work”

When starting, say something like:

“I’m not an HVAC company yet, but I can look at it, diagnose it, and do basic repairs. If it’s something major, I’ll recommend a licensed contractor.”

This protects you and sets expectations.

3. Charge Something (Even If It’s Small)

You’re helping them, but don’t work for free—this trains people to value your time.

Examples:

  • $40–$60 for a tune-up

  • $100 for thermostat install

  • $50–$100 for basic electrical components

  • $0–$20 if it’s immediate family and super quick (optional)

Even a small fee helps cover tools, gas, and parts.

4. Build a Small Starter Tool Kit

When your first starting, you only need basic tools:

Required

  • Multimeter

  • Drill

  • Nut driver set

  • Screwdrivers

  • Shop vac

  • Flashlight

  • Level

  • Hand tools

Nice to have

  • Manifold gauges (if doing refrigerant work + you have EPA 608)

  • Vacuum pump

  • Nitrogen regulator

You can add gear as you get more jobs.

5. Practice on Their Systems

This is the easiest way to get real-world experience:

  • Do full furnace and AC tune-ups

  • Learn to diagnose electrical issues

  • Practice coil cleaning

  • Learn airflow basics

  • Replace capacitors and contactors

  • Take photos of each job for your portfolio

Family/friends homes = the best “training ground.”

6. Give Them Simple Maintenance Plans

Great way to build steady work:

Example:

  • $60–$120 per year

  • 2 tune-ups (spring + fall)

  • Priority service

  • Small discounts on repairs

Even 10 people = recurring income.

7. Ask for Reviews (This matters later!)

Once you eventually go public, you’ll already have:

  • 5-star reviews

  • Photos of your work

  • Real job experience

  • People who trust you

Family and friends are the easiest people to get reviews from.

8. Know When to Say “This is too big for me”

Don’t take on:

  • Full installs (without a license)

  • Major refrigerant leaks (unless certified)

  • Electrical panel work

  • Asbestos duct jobs

  • Anything unsafe

Start small → build confidence → grow naturally.

  1. You’re going to want to have common tools and parts like contractors, capacitors, blower motor and filters look at my list of products to get an idea of what you might want to stock! Parts are especially good to have not only if you need to replace them but they are easier to sell when you have them on you for example

    “hey I did notice this contractor is showing signs of wear it’s still working now but when it goes bad your unit won’t work. I have a new one on me it will be an extra x amount would you like to swap it out?” 9 times out of 10 you will easily get the sale!
