How to Choose an HVAC Contractor in South Florida

Step one: verify the licence yourself

Florida licenses air conditioning contractors at the state level through the Department of Business and Professional Regulation. Anyone doing HVAC work on your home should hold a current licence, and you can check it free in a couple of minutes.

• Go to the DBPR licence search at myfloridalicense.com and search by licence number, business name, or the individual’s name.
• Confirm the licence is current and active, not expired, null or under discipline.
• Confirm the name on the licence matches the company you are actually hiring. A licence belonging to someone who is not involved in the work is a serious problem, and it is more common than it should be.
• Florida uses classes: a CAC licence is a certified air conditioning contractor, valid statewide. Registered licences are limited to specific local jurisdictions.

Ours is listed in the author box at the foot of this page — look it up. Any contractor who hesitates to give you a licence number is answering the question.

Step two: verify the insurance

Ask for a certificate of insurance, and ask for it to be sent directly by their agent rather than as a photograph of a document. You are checking two things: general liability, which covers damage to your property, and workers’ compensation, which matters because an uninsured worker injured on your property can become your liability.

Airo Service carries $1M/$2M general liability and provides a certificate on request. That is a normal thing to ask for and no legitimate contractor is offended by it.

The red flags

• No written estimate. A verbal number is not a quote.
• Pressure to decide today, or a price that expires at the end of the visit. Genuine seasonal promotions exist; “this price only if you sign now” is a technique.
• A large deposit demanded up front, particularly in cash. Some deposit on equipment is normal; a majority of the job before work starts is not.
• They ask you to pull the permit as a homeowner. This shifts liability onto you and often means their licence will not support it. See permits and inspection.
• Quoting a replacement without a load calculation — sizing from the old unit’s badge is guessing with confidence.
• Condemning a system without showing you anything. Ask what the reading was, and what the specification is. A real diagnosis has numbers.
• An unmarked vehicle and no physical address.
• A price far below everyone else. Check what has been left out — the list is in hidden costs of AC installation.
• Refusal to provide model numbers for the equipment being quoted.

The questions worth asking

• What is your licence number, and does the work run under it?
• Can your agent send me a certificate of insurance?
• Is the permit included and pulled by you?
• Will you perform a load calculation before recommending a size?
• What are the model numbers of the indoor and outdoor units, and the AHRI matched rating?
• What is included, and what would be a change order?
• What is your labour warranty, and will you register the equipment with the manufacturer?
• Who does the work — your own technicians or subcontractors?
• What happens if something goes wrong in month eight?

Reading reviews usefully

Volume and recency matter more than a perfect average. A company with two hundred reviews averaging 4.7 is a more reliable signal than one with nine reviews averaging 5.0. Read the negative ones specifically — what you want to see is how the company responded. And be sceptical of clusters of reviews posted within a few days of each other.

Look for reviews that mention the things that matter here: whether they came back, whether the price matched the quote, whether the permit was closed out.

South Florida specifics

• Hurricane zone requirements. Miami-Dade and Broward sit in the High Velocity Hurricane Zone, where equipment anchoring and product approval requirements are stricter. A contractor who works here routinely will handle it without being asked.
• Condo and HOA rules. Buildings frequently have approved-vendor requirements, insurance minimums, elevator and work-hour rules. See condo AC replacement rules.
• Salt-air experience. Coastal properties need coil protection and more frequent condenser attention. A contractor who has never mentioned corrosion has not worked much east of Federal Highway.
• Post-storm caution. After a hurricane, out-of-area operators appear. The licence lookup takes two minutes and is never more worth doing than then.

Getting the comparison right

Collect two or three quotes, and insist each one itemises the same list so you are comparing the same job rather than three different jobs at three different prices. Then weigh the process, not just the number — the reasoning behind that is in brand vs installer.
