How do I verify an HVAC contractor's license in Jacksonville, FL before hiring them?

You have two tools. First, check the DBPR licensing portal at myfloridalicense.com to confirm the contractor holds an active state-issued CAC or Registered Air Conditioning Contractor license. Second, use Jacksonville's Contractor License and Complaint Search at coj.net to verify Duval County registration and workers' compensation status. Always ask the contractor for their license number in writing before signing anything.

Should I just replace my HVAC system with the same tonnage as the old one?

No. Simply matching the old tonnage is a red flag. A qualified contractor should perform actual load calculations based on your home's specific characteristics — ductwork condition, insulation, window type, and layout all factor in. Older Craven homes with original ductwork have very different requirements than newer builds, and an improperly sized system can lead to short-cycling, higher energy bills, and poor humidity control.

What's the difference between a Class A and Class B HVAC license in Florida, and does it matter for my home?

Florida issues different HVAC contractor credentials based on the scope and size of work covered. Class A licenses cover a broader range of systems, while Class B licenses are more limited in scope. For most residential replacements, either may be appropriate, but the contractor should be able to clearly explain which class they hold and confirm it covers your specific job. If they can't explain this, that's a warning sign.

What paperwork should an HVAC company pull before starting work on my home in Craven?

Any legitimate HVAC contractor should pull the required permits and have the work inspected through Jacksonville's Building Inspection Division. They must also handle refrigerant using someone who is federally certified to do so. If a contractor skips permits or inspections, their quote isn't truly comparable to one from a company that includes these steps — and you could face liability or code issues down the road.

How to Evaluate an HVAC Company in Craven, Jacksonville Before You Commit

You've narrowed it down to two or three HVAC companies. The quotes are in, the sales pitches were fine, and now you're staring at proposals wondering which one you can actually trust with your home. If you live in the Craven area of Jacksonville, FL, the decision is more consequential than it might seem — our humidity is punishing, our cooling season is long, and a wrong hire can mean years of short-cycling equipment, higher bills, or a system that never quite dries the air out.

This guide walks through how to evaluate an HVAC company in Jacksonville, FL before you sign anything. Not the marketing questions — the verification steps, the paperwork, and the local specifics that separate a contractor who'll stand behind the work from one who won't.

Start With What Craven Homes Actually Need

Craven sits within Jacksonville's broader housing mix of older bungalows, mid-century ranches, and infill construction. That variety matters. An older home with original ductwork, single-pane windows, and a retrofitted system has entirely different load requirements than a newer build with modern insulation. A good HVAC contractor will notice the difference in the first ten minutes of a walk-through and adjust the sizing math accordingly.

Before you evaluate contractors, know what you're actually buying:

A properly sized system — not just "the same tonnage as the old one"
Ductwork that's sealed and appropriately sized for the new equipment
Refrigerant handling by someone federally certified to do it
Permits pulled and inspections passed with Jacksonville's Building Inspection Division

If a contractor skips any of these, the price on the quote isn't really comparable to one from a company that includes them.

Verify the License Before Anything Else

Florida regulates HVAC contracting under Chapter 489, Part II of the Florida Statutes, administered by the Department of Business and Professional Regulation (DBPR) through the Construction Industry Licensing Board. Any company working on your system in Craven must hold either a state-issued Certified Air Conditioning Contractor (CAC) license or a Registered Air Conditioning Contractor credential tied to local jurisdictional registration.

Jacksonville and Duval County do not issue a separate city HVAC license. Instead, contractors must verify compliance through state and county systems. That means you have two verification tools at your disposal:

The DBPR licensing portal at myfloridalicense.com, where you can confirm the contractor's state license is active and in good standing
Jacksonville's Contractor License and Complaint Search tool at coj.net, which lets you check Duval County registration and workers' compensation status

Ask the company for their license number in writing. A reputable HVAC contractor like King of Home Solutions won't hesitate to provide it — verification is a normal part of the process, not an insult. If a contractor stalls, changes the subject, or claims their "crew leader" is licensed but can't produce a number, that's your answer.

Class A vs. Class B — Ask What They Hold

Florida distinguishes between broader and more limited HVAC/mechanical credentials based on system size and type. The two main classes — Class A and Class B — cover different scopes of work. For most residential replacements in Craven, either can be appropriate, but you want the contractor to be able to explain which class they hold and why it covers your specific job. If they can't articulate that, they may be operating outside their scope.

Confirm Insurance and Workers' Compensation

This is the step homeowners skip most often, and it's the one that costs the most when something goes wrong. Florida law requires HVAC contractors to carry liability insurance and workers' compensation coverage (or hold a valid exemption). Jacksonville's Building Inspection Division specifically directs homeowners to verify a contractor's workers' compensation policy or exemption status before work begins.

Why it matters: if an uninsured technician is injured in your attic or garage, you can end up on the hook. If uninsured work damages your home, you're chasing the contractor in small claims court instead of filing an insurance claim.

Ask for a Certificate of Insurance directly from the insurer, not a photocopy from the contractor's binder. It should list liability limits and workers' comp coverage, and it should be current.

Ask About EPA Section 608 Certification

Anyone handling regulated refrigerants — which is virtually every residential HVAC job involving repair or replacement — must hold EPA Section 608 certification under federal law. This is separate from and in addition to the Florida state contractor license. A company can be properly state-licensed but still send a technician who isn't Section 608 certified, which is a federal problem, not just a paperwork one.

The question to ask: "Is the specific technician coming to my home Section 608 certified?" Not the owner. Not the office. The person putting hands on your equipment.

Insist on a Permit and Inspection

For HVAC installation, replacement, or substantial modification in Craven, a mechanical permit from Jacksonville's Building Inspection Division is required. The permit must be pulled by the appropriately licensed contractor, and the work is subject to local inspection for code compliance.

Some contractors will offer to skip the permit to save you money or time. Don't accept that. An unpermitted install can:

Void the manufacturer's warranty on new equipment
Create disclosure problems when you sell the home
Leave you without recourse if the work fails inspection later
Expose the contractor — and by extension you — to enforcement action

A quote that includes the permit fee and inspection is a quote from a company that plans to be around next year.

Evaluate the Load Calculation and Proposal

Once licensing and insurance check out, look at the substance of what they're proposing. For a home in Craven, ask specifically:

Did they perform a Manual J load calculation, or did they "size by rule of thumb"?
Did they inspect the ductwork, or just quote equipment?
Does the proposal specify equipment model numbers, SEER2 ratings, and warranty terms in writing?
Are refrigerant type, line-set condition, and drain configuration addressed?

Given Jacksonville's humidity, an oversized system is a common — and expensive — mistake. It cools quickly, shuts off before it dehumidifies, and leaves you with a clammy house. A contractor who takes the time to size the system correctly for your specific Craven home is signaling how they'll approach the rest of the job.

Questions to Ask Before You Sign

What does your warranty cover, and for how long?

Manufacturer warranties cover parts. Labor warranties come from the contractor. Get both in writing, along with what voids each.

Who handles warranty service if there's a problem in two years?

You want the answer to be "we do, in-house." Companies that subcontract service create finger-pointing when something fails.

Will you provide a written scope of work before I sign?

Verbal promises don't survive the first misunderstanding. The scope should list equipment, materials, permit responsibility, timeline, and payment schedule.

How do you handle change orders?

If they open the attic and find something unexpected, you want a clear process — not a verbal "we'll figure it out" that turns into a surprise invoice.
