The Great Dane difference
The Jacksonville Beach AC Company That Knows Salt
For more than 20 years Great Dane Heating & Air has kept Jacksonville and Duval County comfortable, with a standing run over the Intracoastal for most of them. A family company with upfront pricing, comfort techs who treat your home like their own, and a soft spot for shelter dogs.
All three beaches are on the route most weeks, and out here the failures repeat — the same corroded fin, the same coil quietly losing capacity a season before anybody notices. It means we are rarely guessing at what failed.
Licensed & Insured
Florida state certified contractor CAC036942, fully insured, and accredited with the Better Business Bureau at an A+ rating. Every tech who pulls into your driveway works under that license.
20+ Years in Service
Two decades across Duval County, with a standing route over the Intracoastal for most of them. The people who answer your call are the same people who show up at your door.
Every Job Gives Back
We’re a proud supporter of the Jacksonville Humane Society. Part of what you spend keeping your home comfortable helps shelter dogs here in Jacksonville find one of their own.

Tell us what it’s doing. We find the real problem, give you the whole number before any work starts, and tell you straight if a repair is not worth your money.
When your air conditioner is past its prime, more AC repair isn’t always the answer. A new, energy-efficient AC installation can end the breakdown cycle, cool your home evenly, and take a real bite out of summer power bills.
Our Jacksonville team gives you the honest math on AC replacement vs. repair, sizes the new system correctly for Florida heat, and leaves the job site cleaner than we found it — just like this install.
Everything here runs in air coming off the ocean, and the outdoor half of your system stands in it year‑round. Four things that changes.
78°Set to 78° — nine months a year
The coilCorrosion from the outside in
Salt settles on the aluminium fins of the outdoor coil and works inward, and for a long while the damage looks purely cosmetic. A coil losing fin material loses its ability to shed heat first and holds refrigerant second — so by the time it leaks, it has usually been quietly costing you efficiency for a season or two.
The distanceA few streets matter
Salt load drops off sharply as you move back from the water, which is why a unit three blocks from the ocean and one west of the Intracoastal are not really in the same climate. Where your house sits changes both what is worth doing and how often it is worth doing it.
The rinseThe cheapest thing that works
Fresh water through the outdoor coil on a schedule takes the salt off before it has time to do anything permanent. It is unglamorous and it is not expensive, and out here it does more for the working life of a system than anything else on this list.
The planningCoastal equipment ages faster
A system at the beach will not give you the same working life as the identical system inland, and planning as though it will is how people end up making the decision in August. Coil coatings and sheltered placement both help. Knowing where yours is in its life means replacing on your schedule instead of the weather’s.
Beaches Service Area
From Beaches Town Center to the Intracoastal
Three small cities in a row, and the distance from the water changes the job more than the address does. This is where the truck actually ends up.
Jacksonville Beach
The length of it, from the pier south. Closest to the water, and the hardest place in the county on an outdoor unit.
Neptune Beach
Small, dense, and almost entirely within reach of the salt. A short run for us and a frequent one.
Atlantic Beach
The north end, including the older streets off Ocean Boulevard where systems have had a long time to meet the air.
Beaches Town Center
The restaurants and shops on the Atlantic and Neptune line — commercial work, where the equipment is usually on a roof and the salt reaches it from every side.
Penman & Third Street
The two north‑south runs everything turns off. If you are between them, we are past your house most weeks.
West of the Intracoastal
Still the Beaches as far as we are concerned, and noticeably easier on equipment than the oceanfront streets.

Straight talk: If somebody tells you your system is “illegal now” because of the refrigerant rules — it isn’t. R‑410A systems can still be serviced. New equipment moved to R‑454B in 2025 and R‑410A production is stepping down, so topping off an older system gets pricier every year. That’s a reason to plan, not a reason to panic‑buy tonight.

A Company Named by a Dog
The Dane on the van is not decoration. Great Dane Heating & Air was built by people who are openly sentimental about animals, and the idea from day one was that the business ought to leave the pet population of Duval County better off than it found it.
In practice: rescue events, time given to the animals still waiting at the shelter, and a Rescue of the Week put in front of everyone who follows us. It is also why we are a Paw Partner Corporate Sponsor of the Jacksonville Humane Society.
A working air conditioner is comfort. Out here it is also equipment standing in salt air every day of the year, which makes looking after it rather less optional than it is anywhere else in the county.
Vetted people in your home
Florida state certified — licence CAC036942 — fully insured, and BBB accredited at an A+ rating. The same small crew every time, and the same crew that knows which failures out here are the salt and which are not.
Salt, sand and what you breathe
The same air that corrodes a coil carries sand and damp indoors with it. Filtration, purification and humidity control handle what is in the air, which this close to the water is never only a question of temperature.
Shown, not just told
If the coil is finished you get to look at it, with the readings beside it, before anybody talks about replacing anything. Our work is guaranteed — that is the whole point of the name on the truck.

Paul came out and replaced our blower motor and saved the day. He fielded my call on Sunday evening, then did the service Monday afternoon. Friendly, efficient, and professional.
After years of feeling vulnerable to dishonest HVAC companies, a neighbor put me in touch. He quickly earned my trust — quick to return calls, reasonable rates, and he’s never tried to sell me things I don’t need.
We’ve used him for everything from small tweaks to replacing our entire unit. Quick, reliable, honest, and clean — and he beat the prices of every competitor. Yes, we priced out seven.
Fast and efficient, unbelievably affordable pricing. He quickly figures out the problem and explains it in a way anyone can understand. You automatically feel like you can trust him.
Our A/C went down and the team showed up Monday morning first thing. We had cool air flowing in no time. The crew was fast, clean, and finished under time.
Mike and the team were very professional, friendly, and knowledgeable. The price was not unreasonable. So happy we found this company — we know we will be taken care of in the years to come.
Just had Great Dane install a new A/C in my home. Mike came to my home, saw what I had, and I told him what I wanted installed. There was absolutely no sales pressure.
Mike came out and gave an estimate with no fluff, which is what I like. He was honest and professional. The team that installed the unit worked well together and the work performed was stellar!
The questions Jacksonville asks us most — straight answers, no jargon.
The outdoor unit looks rusty. Is that just cosmetic?+
Sometimes, and sometimes it is the whole story. Surface rust on the cabinet is cosmetic. What matters is the coil behind it: salt attacks the aluminium fin first, and a coil that has lost fin material sheds heat badly long before it ever leaks. We can tell you which of the two you are looking at in a few minutes.
The system runs constantly but the house is comfortable. Should I care?+
Yes, because out here that is often the first measurable sign of a corroded coil. As the coil loses its ability to reject heat, the system makes up the difference with run time — so the power bill moves well before the comfort does. It is worth a set of readings rather than waiting for it to stop.
Does being closer to the ocean genuinely change anything?+
Considerably. Salt load falls away quickly with distance, so a house on the oceanfront streets, one near Penman and one west of the Intracoastal are not on the same maintenance schedule and should not be treated as though they are.
Is there equipment made for this?+
There is. Coil coatings and corrosion‑resistant cabinets exist precisely because coastal installations fail differently from inland ones, and they are worth raising when a system is being specified for a house this close to the water. We will talk the options through against where your house actually sits.
Does it matter where the outdoor unit sits?+
More here than almost anywhere. Direct exposure to onshore wind and spray is harder on equipment than a sheltered side of the house, and a few feet of difference in placement changes how often it will need attention. We look at that before the pad goes down rather than after.
My system is not old, but the coil has gone. Is that normal?+
At the beach it is not unusual, and it is not a reflection on the equipment. Coastal air shortens the working life of the outdoor half of a system, which is why the replacement conversation here looks different from the same one five miles inland. We will show you the coil rather than ask you to take our word for it.
Can I just hose the unit down myself?+
You can, and doing it beats not doing it. Gentle fresh water through the coil, power off, and no pressure washer — pressure folds the fins and does more harm than the salt was doing. What a service visit adds is getting into the coil properly and measuring what it is actually doing afterwards.
What is the $99 HVAC Refresh & Tune‑Up?+
A full seasonal check‑over of the system you already have — measurements taken, the parts that genuinely foul cleaned, and a straight answer about what needs attention and what does not. At the beach the coil rinse and inspection are the parts that earn it back twice over. Cannot be combined with any other offer, one per household.
Does the sand get inside the system?+
Some of it does, and it ends up in the filter and eventually on the indoor coil. Put that together with the damp that comes of living this close to the water and you have an indoor coil fouling faster than any schedule assumes. Filtration and an honest look at that coil on a maintenance visit cover it.
Do you cover all three beaches?+
Jacksonville Beach, Neptune Beach and Atlantic Beach are all inside the normal service area at the same pricing as anywhere else we go, along with the streets west of the Intracoastal. Great Dane is licensed in Florida as CAC036942, which you are welcome to look up before you let anybody into the house.
Will you tell me if I do not need the work?+
Yes, and out here it cuts both ways. Sometimes a unit that looks alarming is working perfectly well, and sometimes one that looks tidy has a coil that is finished. You get the readings either way, and the decision stays yours.
Anything worth checking before I call?+
Three things, none of which cost anything. Check the breaker for the air handler and for the outdoor unit. Look at the filter, because a collapsed one starves the system and imitates a much bigger fault. And look at the outdoor coil in daylight — if the fin surface looks powdery or is coming away in places, say so on the phone.
