Air Conditioner Repair & Replacement
What the Storms Do to the Electronics Inside
Florida takes more lightning than any other state, and out here the lines are mostly overhead. The part of your system that notices is not the part most people worry about.

Modern systems are run by low‑voltage control boards, and those are the cheapest thing in the cabinet for a surge to damage. The compressor usually survives what the board does not — which is why a system that seems completely dead after a storm is often a comparatively small repair.
A surge can leave a capacitor or a contactor weakened rather than finished, and the part then gives out under load some days afterwards. People connect the two events about half the time. We connect them most of the time, because we see the pattern across a whole street.
Nothing dries the air while the power is down, so a house comes back from a long outage damp as well as hot. Bringing the temperature down is the quick part. Getting the moisture back out is what actually makes it feel right again.
Power coming back hard trips breakers and disconnects, and a system that will not start after an outage very often has nothing wrong with it. It is the first thing we check and the first thing worth checking yourself before anybody is called out.
Orange Park Service Area
From Kingsley Avenue to Doctors Lake
The oldest suburb on the Clay side, and one where the power goes out often enough that it shapes what fails. This is where the truck actually ends up.
The original town, under big trees and on overhead lines. More storm‑related calls per street than anywhere else on this run.
The spine through the middle, residential behind and commercial along it.
The water side, where the air stays damp later into the evening than it does inland.
The commercial corridor — shops, restaurants and offices we cover on the commercial side.
Established streets with established equipment, and the repair‑or‑replace conversation to go with it.
The newer end of the run, where the equipment is young and the questions are about setup rather than failure.

Let’s Figure This Out Together
No quote needed, no email, no phone number — just tell us what it’s doing and we’ll give you our honest read.
1How old is the system?
2What’s it doing? tick all that apply
3How often has it needed fixing?
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.

Why a Dog Is on the Paperwork
Great Dane Heating & Air was set up by people who are shameless about animals, and the name was the first decision made. The idea behind it was that a heating and air company could quietly be worth something to the pet population of Duval County.
In practice that is rescue events, time spent with the animals still waiting at the shelter, and a Rescue of the Week shared with everyone who follows us. It is also why we are a Paw Partner Corporate Sponsor of the Jacksonville Humane Society.

Comfort That Survives the Summer Storms
A working air conditioner is comfort. Out here it is also a box full of electronics attached to a power supply that goes down and comes back several times a season.
-
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, which counts for something when the whole street called the same afternoon.

The air after the house shuts up
A house that has been closed and warm through an outage comes back damp, and damp is what everything unwelcome grows in. Filtration, purification and humidity control are what bring it back rather than simply making it cold again.

A board is not a system
If a surge took out a control board you will be told it is a board, not sold a system on the strength of a bad afternoon. Our work is guaranteed — that is the whole point of the name on the truck.

Barking Good News From Orange Park
★★★★★ 4.9 out of 5 across 74 Google reviews
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.
Beyond reproach. Prompt, professional, and had the problem diagnosed and repaired the same day. Integrity, honesty and great customer service.
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.
They replaced our entire AC unit and did some duct work. Professional staff and excellent communication. Top quality service and work!
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!

No fluff and no scare stories — the same answers we give on the phone, written down so you can try the free fix first.

FAQ
Good Questions to Ask
The questions Jacksonville asks us most — straight answers, no jargon.
The power came back but the air conditioning did not.
Start with the breakers and the outdoor disconnect, because an outage frequently trips one and nothing else is wrong. If those are fine, the next most likely thing is a control board rather than the compressor — boards are the cheapest component in the system to damage and the easiest to mistake for a total failure.
Everything worked through the storm and quit two days later.
That is common enough that we look for it. A surge can weaken a capacitor or a contactor without finishing it, and the part then fails under load a day or a week later. It looks like coincidence and it is usually cause and effect.
Is a lightning strike going to destroy the whole system?
Rarely, and that is worth knowing before somebody quotes you one. A direct strike is genuinely destructive and it is also uncommon. Far more often what reaches your equipment is a surge down the line, and what it finds is the low‑voltage electronics. We will show you what is actually dead.
Is surge protection for HVAC worth it?
In this part of the state it is a reasonable thing to ask about, and it is a category rather than a magic box — protection at the panel and protection at the equipment do different jobs. It will not stop a direct strike. It does deal with the everyday surges that quietly shorten the life of a control board.
The insurance adjuster wants to know what failed.
Then you want somebody who will write down what actually failed and why, with the readings, rather than a line that says the system is bad. We will document what we found in plain terms. What we will not do is describe damage we did not measure.
The system is old and the storm finished it. Replace or repair?
That depends on what the storm actually did, which is why we look before answering. If a surge killed a board on a twenty‑year‑old system, you are choosing between a modest repair on old equipment and a replacement you were probably heading toward anyway. Both are legitimate. You should get the numbers for each.
Should I turn the system off when a storm is coming?
Switching it off at the thermostat does very little. Killing power at the breaker does more, and it is a reasonable thing to do if a severe storm is genuinely overhead. What we would not recommend is doing it every time the sky darkens in July, because the humidity that builds while it is off has its own cost.
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. Out here it is also when we check the electrical connections and the contactor, which is where storm wear shows up first. Cannot be combined with any other offer, one per household.
The house smells musty after a few days without power.
It will. Nothing has been removing water from the air, and in a Florida summer that adds up quickly. Running the system normally again fixes most of it; where it does not, the filter and the indoor coil are the places to look rather than assuming the worst about the walls.
Do you come over to Clay County?
Regularly. Orange Park, Kingsley, Doctors Lake, Oakleaf and the streets off Blanding are all inside the normal service area at the same pricing as anywhere else we go. 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 after a storm that matters more than usual, because it is exactly when people get told the system is finished. A tripped breaker and a dead board are both very different from a dead system, and you will be told which one you have.
Anything worth checking before I call?
Three things that cost nothing. Check the breaker for the air handler and for the outdoor unit, and check the disconnect box outside — after an outage that is the answer more often than anything else. Look at the filter. And note whether the outdoor fan is turning at all; that one detail narrows it a long way.
Done Right the First Time
Honest, upfront pricing and work we stand behind 100% — that’s the Great Dane guarantee.
