Family Air Experts installs and replaces air conditioning throughout Sebastian, from Sebastian Highlands and the riverfront streets to Collier Club, Sebastian River Landing, Cross Creek Lake Estates and the newer builds at Spirit of Sebastian. The Highlands on its own is roughly 9,271 homes at a 1993 median build, which is the single largest block of same-age equipment anywhere on our patch.

Signs It Is Time to Replace Your AC
A system rarely fails overnight. These are the signs it is moving out of repair territory. In the Highlands, where thousands of houses went up within a few years of each other, they tend to show up across a neighborhood rather than one house at a time.
Warm air at the vents
It runs all afternoon and still cannot hold the setting on a hot day.
Weak airflow
Airflow that improves for a few weeks after a service call and then drops off again.
Short cycling
Cooling that comes on in short bursts and goes off again, returning that way after each repair.
Water near the air handler
Drain and coil trouble coming back on a system that has had it before.
Ice on the line set
Ice on the line set after a recharge, which on a thirty-year-old Highlands system means a leak rather than a top-up.
Humidity that will not drop
Humidity that will not clear even when the thermostat reads right, usually a sign the system is oversized for the house.
A power bill that jumped
Power bills climbing year on year while nothing about the house has changed. In an owner-occupied house that adds up over the life of the system.
New noises
Noises getting louder or changing character rather than holding steady.

What Our Installation Customers Say
Here is what Sebastian homeowners say after we have installed for them.
What a New AC System Costs and How We Quote It
A new system is quoted as one number covering equipment, labor, the permit and the inspection, and you see it before anything is ordered. Sebastian charges a flat $75 for the change-out permit, so that part of the number is known up front rather than estimated.
Clearly and transparently
One figure covering equipment, labor, the $75 city change-out permit and the inspection, agreed before anything is ordered.
Sizing comes first
We size the system to the house rather than copying the label off the old unit. In the Highlands the houses are of a kind, around 1,622 square feet on average, but they are not identical, and assuming they are is how a street ends up with a row of oversized systems.
What makes one big or small
Efficiency level moves the price most, then the size of the system, then whether the duct work and the electrical need attention. In an owner-occupied house that you plan to keep, the efficiency step usually pays back.
When repair stops making sense
When a repair on an older system approaches what a replacement is worth, we put both numbers in front of you rather than steering you. On a 1990s Highlands system the second significant repair is usually the moment to stop.
Want a ballpark before you book an estimate? Call 772-971-8587 and tell us whether you are in the Highlands or on the river and what the system is doing. We will tell you the range a house like yours usually lands in. See a free replacement estimate or financing options.

During your free estimate, we will review both Synchrony and Service Finance options so you can pick what feels right for you.
What Happens When You Book an Installation
Same-day service is usually available across all four counties when you call before too late in the afternoon. Here is exactly how the visit goes.
Call or Book Online
Tell us the house and what the current system is doing. We come out and measure rather than quoting over the phone.
We Text Ahead
You get the installers’ names and an honest arrival window on install day, not a four hour block.
Sizing Visit
We size the system to the house, look at the duct work and the electrical, and show you what we found before recommending equipment.
Price Before Work
You approve one price before anything is ordered. The permit and the inspection are ours to handle, not yours.
Install and Commission
We install, start up and commission the system, register the manufacturer warranty in your name, and walk you through it before we leave.
Watch a real AC Installation
Start to Finish, here’s how we do it.
AC Installation Across Sebastian
We install and replace complete residential cooling systems on every major brand, across the Highlands, the riverfront streets, Collier Club, Sebastian River Landing and the newer Spirit of Sebastian builds. If it cools a Sebastian home, we can size it, fit it and stand behind it.
Full System Replacement
Condenser, air handler, coil and line set replaced as a matched set, which is what the efficiency rating is based on and what the FPL rebate requires.
Ductwork Repair
Thirty-year-old duct work is the usual reason a new system disappoints in the Highlands. We look at the duct work before quoting the equipment rather than after.
Permits and Inspections
Sebastian runs its own building department rather than going through the county, and it charges a flat $75 for an air conditioning change-out. We pull it, book the inspection and see it signed off. Contractors from outside the city routinely file with the county by mistake and stall the inspection.
Surge Protection
Storm surges are what finish off the electrical side. Protection fitted at install costs a fraction of what it saves.
Thermostats and Controls
A new system deserves a thermostat that can actually run it, wired to the right equipment rather than whatever was on the wall.
Ductless Mini Splits
For additions, garages, workshops and rooms the ducts never reached properly.
Why Sebastian Systems Wear Out Early
A system in this climate does more work in ten years than the same unit would do in twenty up north. These four are why replacement comes sooner here.
Lagoon Salt, Not Ocean Salt
Sebastian sits along the Indian River Lagoon rather than directly on the Atlantic, so salt exposure here is real but milder than on the barrier island a few miles east. Manufacturers put the carry at up to two miles inland, which covers the riverfront streets. Out in the Highlands it is far less of a factor than run time is.
A Neighborhood Aging Together
Sebastian Highlands is roughly 9,271 homes with a median build year of 1993 and an average size around 1,622 square feet. Equipment installed with houses that went up together reaches the end together, which is why replacement here comes in waves.
Detached Houses, Owner Occupied
Sebastian runs about 87% detached and 85% owner-occupied, quite unlike Vero Beach down the road. People here keep their houses, which makes efficiency worth more over the life of the system than it is in a property that changes hands every few years.
Year-Round Run Time
Around 3,555 cooling degree days, and zero heating degree days from May through October. A system installed here runs most of the year rather than seasonally, so sizing for the worst week matters.

Why Sebastian Homeowners Choose Us to Install
We are a family business in Fort Pierce and a Lennox Premier Dealer, and Sebastian is on our regular route rather than an occasional trip. The people who quote your system are the people who install it, our installers are background checked, the price is agreed before anything is ordered, and we hold a Florida 252 certified license. More on why homeowners choose us.
The Family Clubs
Most manufacturers require documented annual service to keep a parts warranty valid, so the maintenance plan is not an upsell on a new system, it is what protects the coverage you just paid for. Once or twice a year, your choice, with priority scheduling and no overtime charges on select plans.
Financing Available
A new system is a planned purchase for most people rather than an emergency. Financing lets you match the payment to the savings instead of the invoice and on full system replacements, so you can spread the cost instead of putting off the fix.
What Our 252 License Means for Your Warranty
Family Air Experts carries a Florida 252 certified HVAC contractor license, the state level certification rather than a city registration. That is what lets us pull the Sebastian change-out permit with the city rather than filing in the wrong place, and it is what keeps your manufacturer parts coverage in force. Nearly every manufacturer requires licensed installation, and an unlicensed install can void coverage on day one.
You’re Not Locked in with Another Company
Not often mentioned, but the company that installed your unit, doesn’t have to be the one who processes the warranty. Family Air Experts holds a 252 License with the state of Florida, allowing us to handle any warranty claims from any HVAC Installer.
Your Manufacturer Warranty Stays Valid
Work performed by a 252 licensed contractor keeps your parts coverage intact. We document what we did and what we replaced, so there is a record when you need it.
We Handle the Claim Paperwork
If a covered part fails, [we file the claim with the manufacturer and you pay only labor]. Confirm exactly how we handle this before publishing.
F.A.Q.
Frequently Asked Questions
How much does a new AC system cost in Sebastian?
Three things move the number: the size the house actually needs, the efficiency level you choose, and whether the duct work and electrical can support it. Sebastian adds a flat $75 change-out permit, which is inside the price rather than added later. FPL serves the county and pays $200 on a qualifying changeout at 15.2 SEER2 or above installed by a participating contractor, which we are. Call 772-971-8587 and tell us about the house.
How long does an AC installation actually take?
Most straight changeouts are finished in a single day. Where the duct work needs attention first, or the Sebastian inspection has to be scheduled, we tell you that up front rather than on the day.
Do you handle the permit and the inspection in Sebastian?
Yes, on every job. Sebastian permits its own work rather than deferring to the county, at a flat $75 for an air conditioning change-out. We pull it, book the inspection, see it signed off and register the manufacturer warranty in your name.
Should I repair or replace my air conditioner?
Under ten years old with a small part failure, repair it. Past fifteen, or facing a compressor or a leaking coil, replacement is usually the better spend. A 1993 median build in the Highlands puts a great many systems here well past that line, often on their second unit rather than their first. A free estimate will tell you which side of it you are on.
Are you licensed and insured in Sebastian?
Yes. We hold a Florida 252 certified HVAC license and carry full liability insurance. That certification is also what keeps your manufacturer warranty valid. What the 252 license covers.
Does using a licensed contractor matter for my manufacturer warranty?
Not when a licensed contractor does the work. Most manufacturers require documented licensed service to keep parts coverage in force, which is exactly why an unlicensed handyman repair is a risk on a system still under warranty.
Do you work on brands other than Lennox?
Yes. We are a Lennox Premier Dealer, but our technicians service every major residential brand.
Do I permit through Sebastian or through the county?
Through the City of Sebastian, at a flat $75 for an air conditioning change-out. This catches people out, because the county Building Division permits both unincorporated county and the City of Vero Beach, so it is easy to assume it covers Sebastian too. It does not, and filing in the wrong place is what stalls an inspection.
Need to cool a smaller area?
