🔐 Why Installer Licensing Matters 

After buying an AC system online, installation isn't just the final step it's where many buyers slip up. Using a licensed HVAC professional ensures the unit is installed to code, connected correctly, and eligible for full warranty coverage.

Unlicensed contractors may offer lower prices, but they often cut corners, lack proper certifications, or skip essential safety steps. These shortcuts can cost you far more in repairs, failed inspections, or denied warranty claims down the road.

🔎 How to Check HVAC Installer Credentials 

A truly qualified HVAC contractor won’t hesitate to show proof of:

• State license (e.g., CSLB in California, TDLR in Texas)
  

• EPA Section 608 certification for refrigerant handling
  

• Bonding and liability insurance in case of property damage
  

• Brand-specific training (especially for systems like Goodman or MRCOOL)

You can verify most of these by visiting your state’s contractor licensing board, such as the California Contractors State License Board (CSLB) or by checking EPA's list of certified technicians.

If they’re missing any of these, it’s best to move on.

🧰 Where to Find Qualified HVAC Installers 

Reputable HVAC professionals are easier to find than ever if you know where to look. Start with these trusted directories:

• The NATE contractor locator, which lists technicians certified in HVAC performance and safety
  

• The ACCA directory for contractors who follow nationally recognized HVAC installation standards
  

• Brand-specific dealer networks like Goodman’s Find a Dealer tool
  

• Recommendations from your local building department or permit office
  

When calling around, ask if the installer has experience setting up systems purchased online. Some won’t touch customer-supplied equipment, while others specialize in it.

🚩 Red Flags to Watch Out For 

Even if someone shows up with tools and a truck, that doesn’t mean they’re qualified. Watch out for these warning signs:

• No verifiable license or certification
  

• Requests for full payment upfront or “cash-only” deals
  

• No written contract or vague job scope
  

• Refusal to pull permits when required by code
  

• Lack of references or avoidance of past project photos

Hiring someone just because they’re “available now” can backfire quickly. If your $3,000 central AC system is installed wrong, the manufacturer won’t cover it even if the unit is brand new.

🛡️ How Installation Affects Your Warranty 

This is where many online buyers run into trouble. Most major brands like Goodman, MRCOOL, and Cooper & Hunter require licensed installation to maintain full parts coverage. If you install the system yourself or hire someone unlicensed, you could void the warranty entirely.

For instance, Goodman’s warranty terms clearly state that units must be installed by a licensed HVAC professional, and MRCOOL’s documentation reinforces this even for their “DIY” labeled systems.

Some utility rebates and energy incentives also require proof of licensed installation to qualify. If you skip this step, you might lose hundreds in potential savings.

🙋 FAQ

Q: Do I need a permit to install an AC I bought online?

A: Yes, in most areas, even DIY or replacement jobs require a permit. A licensed installer should handle this for you.

Q: Will licensed pros work with online-bought units?

A: Many do, especially if the equipment meets brand and code standards. Just ask upfront.

Q: Can I install a mini-split myself?

A: You can, but it may void your warranty and local building codes. Always check EPA and permit requirements.

Q: How much does installation typically cost?

A: Depending on your system and location, expect $1,200–$3,500. Larger systems or multi-zone installs may cost more.

Q: Why does license status affect warranties?

A: Brands want assurance that the unit is installed to spec. Faulty installs lead to product failures and they won’t cover those without licensed documentation.
