How to Choose an AC Company in the Florida Keys

September 24, 2026
3 minutes

Ask around the Keys for the best AC company and you'll get a dozen different names. Most of the time, the answer depends on what went wrong, where you live, and who showed up when it mattered.

So instead of telling you we're the best (our customers think so!), here's what we'd look for if we were hiring an AC company down here. Use it to compare anyone, including us.

‍

1. A Florida license you can actually look up

Florida requires HVAC contractors to be licensed through the state, and you can check any contractor's license yourself on the Florida DBPR license lookup at myfloridalicense.com. It takes about a minute. Look for an active license in the company's or owner's name. Also ask about insurance, because a crew working on your roof or in your attic without it puts the risk on you.

Island Air Control is licensed, insured, and bonded.

‍

2. Experience with Keys conditions, not just Florida conditions

An AC system in the Keys works harder than almost anywhere else in the country. It runs year-round, it fights constant humidity, and it sits in salt air that corrodes coils, fins, and electrical connections. A system that might last 15 to 20 years in a cooler climate typically lasts 8 to 12 here. (Here's how salt air affects your AC system.)

A company that works in the Keys every day knows what salt damage looks like early, why outdoor units need more frequent attention, and why we recommend servicing your system twice a year instead of once. Ask how long they've been working in the Keys specifically.

Island Air Control has served the Florida Keys since 2009, from our shop in Islamorada. Meet our team.

‍

3. Real 24/7 emergency service

AC failures don't keep business hours. In August, a dead system turns into a real problem within hours, especially for older residents, pets, and vacation rentals with guests arriving.

Ask any company you're considering: if my AC quits on a Saturday night, will someone answer? Will they come out?

We offer 24/7 emergency AC repair. Call (305) 852-4042 any time.

‍

4. They actually cover where you live

The Keys are long, and "we serve the Keys" can mean a lot of things. Before you book, confirm the company regularly works in your town and doesn't just list it on the website. That affects how fast they can get to you and whether they'll come back for follow-up.

We serve Ocean Reef, Key Largo, Tavernier, Islamorada, Duck Key, and Marathon. See all our service areas.

‍

5. Factory certifications (and why they affect your warranty)

Manufacturer certifications aren't just badges. They require factory training, and with some brands they unlock longer warranties than a standard installer can offer.

Island Air Control is a Mitsubishi Electric Elite Diamond Contractor, the highest tier in Mitsubishi's contractor program. On qualifying residential installs registered within 90 days, that can extend parts and compressor coverage up to 12 years. We're also a Rheem Pro Partner, with up to 10 years of coverage on qualifying registered Rheem systems. We handle the registration for you.

‍

6. Straight answers on repair vs. replace

A good AC company will tell you when a repair makes sense, even when a new system would be the bigger sale. As a general rule, replacement starts to make more sense when a system is over 10 years old and a repair would cost around half the price of a new unit. Below that, a repair is often the right call. (More on repair vs. replacement in the Keys.)

If you're told you need a new system, it's fair to ask why, and to get it in writing.

We offer free estimates on new system installation and replacement, and financing is available.

‍

7. Reviews that mention people by name

Star ratings help, but read the reviews themselves. Look for reviews that mention specific technicians, specific problems, and how the company handled something going wrong. That tells you more than a five-star rating with no comment.

Island Air Control is BBB A+ rated. Read what our customers say on our reviews page.

‍

8. They handle commercial work too, if you need it

If you own a restaurant, bar, hotel, or rental property, you need a company that can work on commercial systems, refrigeration, and ice machines, not just residential units. It's easier to have one team that knows your whole property.

We service commercial HVAC, refrigeration, and ice machines for restaurants, resorts, hotels, and businesses across the Keys.

Frequently asked questions

Who is the best AC company in the Florida Keys?

‍It depends on what you need and where you live. The best choice is a licensed, insured company with years of experience in Keys conditions, real 24/7 emergency service, regular coverage in your town, and factory certifications that extend your warranty. Island Air Control has served the Keys since 2009 from Islamorada and is a Mitsubishi Electric Elite Diamond Contractor and Rheem Pro Partner.

‍

How do I check if an AC contractor is licensed in Florida?

‍Search the contractor's name or license number on the Florida DBPR license lookup at myfloridalicense.com. It shows whether the license is active.

‍

How often should AC be serviced in the Keys?

‍Twice a year: once in spring before peak heat, and once in fall after heavy summer use. Salt air and year-round operation wear systems out faster than inland. Learn about our maintenance plans.

‍

How long does an AC system last in the Florida Keys?

‍Typically 8 to 12 years, compared with 15 to 20 years in cooler climates, because of year-round use and salt air corrosion.

‍
