Family Air Experts installs high-efficiency air conditioning across Martin County, where the median home was built in 1986 and the 1970s and 1980s together account for about 46% of the entire housing stock. That is roughly 39,000 homes now thirty-five to fifty-five years old. Martin County also requires a Manual J load calculation and a duct tightness test on a new system, so the sizing is documented and the ducts are verified before we hand it over.

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 Stuart, where only 27.6% of housing is single-family detached, that often also means a closet air handler and an association to satisfy, both of which are easier to plan for than to discover on the day.
Warm air at the vents
It runs right through the afternoon and still will not bring the house down to the setting on the thermostat.
Weak airflow
Airflow that improves for a few weeks after a service call and then drops off again.
Short cycling
Cooling that starts and stops in short bursts, coming back after each repair.
Water near the air handler
Drain and coil trouble that returns on a system with a history of it, which in a closet air handler usually shows as a ceiling stain first.
Ice on the line set
Ice on the line set that returns after a recharge. On a forty-year-old system that points at a leak, not a top-up.
Humidity that will not drop
Humidity that hangs about even when the temperature reads fine, common where a system was oversized to compensate for leaky ducts.
A power bill that jumped
Power bills climbing year on year while nothing about the house or the household has changed.
New noises
Noises that are getting worse or changing character rather than holding steady.

What Our Installation Customers Say
Here is what Martin County 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. Martin County also requires a documented load calculation and a duct tightness test, so we tell you up front what that adds rather than letting it appear later as an extra.
Clearly and transparently
One figure covering equipment, labor, the 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, which in Martin County is not just good practice but what the Manual J requirement is there to enforce. An oversized system cools fast, shuts off early and leaves the house damp.
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. With a duct tightness test required here, ducts that would have been left alone elsewhere sometimes have to be addressed.
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. With 46% of the county’s housing built in the 1970s and 1980s, a lot of Martin County systems are reaching that point together.
Want a ballpark before you book an estimate? Call 772-971-8587 and tell us what the system is doing and whether you are in a condo, a townhome or a detached house. We will tell you the range a house like yours usually lands in and what moves it. See a free replacement estimate or financing options.

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 Martin County
We install and replace complete residential cooling systems on every major brand, from the condos and townhomes in Stuart to the detached homes in Palm City and the manufactured housing in Hobe Sound and Indiantown. If it cools a Martin County 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, what the FPL rebate requires, and what the Manual J is calculated against.
Ductwork Repair
A duct tightness test is required here, so duct work is not an afterthought on a Martin County install. We look at it before quoting the equipment, because new equipment on leaking ducts will not pass and will not perform.
Permits and Inspections
Martin County has six permitting authorities. The county permits all of the unincorporated communities, which includes Palm City, Hobe Sound, Jensen Beach, Port Salerno, North River Shores and Rio, while Stuart, Sewall’s Point, Ocean Breeze, Jupiter Island and Indiantown each run their own. The county also requires a Manual J load calculation and a mandatory duct tightness test on a new system. We handle all of it.
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 Martin County 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.
Salt Air, Where It Actually Applies
The coastal strip and the barrier island take salt year round, and near the water a corrosion-resistant coil is usually worth the upgrade. Worth saying plainly though: Palm City and Indiantown are fully inland, and a blanket warning about salt air would be wrong for two of the county’s largest communities.
Age, More Than Anything
With 46% of the housing stock built in the 1970s and 1980s, most replacements here are systems that have simply reached the end rather than failed early. That is a different conversation from a ten-year-old unit with a bad part.
Seasonal Vacancy
The county’s own 2025 capacity analysis counts 6,166 seasonal vacant units in unincorporated Martin against only 1,744 true excess vacancies. Jupiter Island runs 47.7% vacant. Systems that idle through the summer tend to fail on arrival rather than gradually.
Storm History
Frances and Jeanne came ashore at the south end of Hutchinson Island three weeks apart in September 2004, the same stretch of coast twice. Surge protection on a new system is inexpensive next to a control board.

Why Martin County Homeowners Choose Us to Install
We are a family business in Fort Pierce, one county north, and a Lennox Premier Dealer, so 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 county registration. In a county with six permitting authorities and a code that requires a documented load calculation and a duct tightness test, that certification is what lets us pull the permit and sign the work off wherever your address falls, 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 Martin County?
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. Martin County adds two requirements that are part of doing it properly here, a Manual J load calculation and a duct tightness test, and we take care of arranging both. 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 a condo or townhome needs association approval first, or the permit sits with Stuart, Sewall’s Point, Ocean Breeze, Jupiter Island or Indiantown rather than the county, we tell you that up front rather than on the day.
Do you handle the permit and the inspection in Martin County?
Yes, on every job, with whichever of the six authorities covers your address. A changeout requires a permit throughout the county and it is not optional. We pull it, arrange the load calculation and the duct test, 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. With the median county home built in 1986, a great many systems here are well past the point where that tips. A free estimate will tell you which side of it you are on.
Are you licensed and insured in Martin County?
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.
What is a duct tightness test and why do I need one?
It measures how much air your duct work leaks. Martin County requires it on a new system, and it is a sensible requirement: leaky ducts in a hot attic waste a meaningful share of the cooling you just paid for. If yours do not pass, we would rather tell you before the equipment goes in than after.
Need to cool a smaller area?
