Why Sizing and SEER2 Matter
A new system is the biggest comfort decision a homeowner makes, and in a climate where the AC runs most of the year, sizing it right matters more than the brand on the box. A/C Now installs and replaces high-efficiency systems across the Treasure Coast and northern Palm Beach County, matching equipment to your actual home instead of a rule of thumb.
Cooling load isn't uniform across this region — a block home near the water in Jensen Beach gains and sheds heat differently than a two-story in Palm Beach Gardens or a ranch in Fort Pierce. We size the system to your home before we quote, so you're not paying to over-cool or fighting hot rooms after the install. With long, humid summers this far south, right-sized high-SEER2 equipment is what protects both your comfort and your power bill — and we handle permitting and haul-away so the changeover stays clean.

Ductless Mini-Split Installation Across Martin County
A Martin County address can fall under the county's building department for unincorporated land or under one of the municipalities, such as Stuart, Sewall's Point, Ocean Breeze or Jupiter Island. Requirements and inspection scheduling are not the same between them, and the address decides which set applies.
That can move a start date further than any equipment choice does, so it is worth knowing early.
They agree on one thing. A condenser is equipment left standing outdoors, so it has to carry wind loads — a rated pad or bracket, the specified fasteners, and documentation an inspector can read. A unit resting on a loose paver or strapped to a fence will not pass here, and correcting it afterwards means disturbing pipe already cut to length.
HVAC Equipment & Environmental Factors in Martin County, FL
Martin County's homes run from older waterfront estates and mid-century ranch homes on large lots to newer gated communities around Jensen Beach and Palm City. They sit at very different points in their equipment life and raise very different installation questions, so A/C Now sizes every new system to the house with a load calculation instead of matching the old unit's tonnage.
Every Martin County system replacement needs a permit before the job starts, and the finished installation is inspected under it. Depending on the address, that permit comes from the county building department or from a municipality such as the City of Stuart, and A/C Now pulls it on every replacement and hauls the old equipment away. How soon an inspection can be scheduled depends on that department, so if the start date matters, say so when you book.
🌧️ Climate Reality Check: High Water Table & Humidity Control
Long, humid summers make moisture removal as important as cooling, and an oversized system that cools fast and shuts off leaves the air damp. Downpours on ground with a high water table can also leave a unit at grade standing in water; an elevated equipment stand, which A/C Now installs, lifts it clear.
Where a Martin County home sits shapes what its outdoor unit needs. On low ground along Palm City's South Fork, high water after a heavy storm is the main threat to a unit sitting at grade. Along Jensen Beach's Indian River Lagoon waterfront, salt air is the bigger problem, so factory-coated coils and stainless hardware are worth asking about, along with a regular fresh-water rinse of the outdoor coil. In downtown Stuart and in any community with design rules, check whether the outdoor unit's location or screening needs approval before the work is scheduled.
Frequently Asked AC Installation Questions
Common questions about AC replacement, SEER2, warranties and permits.
Our Martin County home is a 1965 CBS ranch with original interior walls — we can't run new ductwork without major disruption. What are our options for a full HVAC replacement?
You very likely won't need new wall runs. In most 1960s concrete block ranch homes the ducts already run overhead, with a trunk in the attic and branch runs to ceiling registers, so the walls never come into it. Attic ductwork that old is often leaky, crushed or undersized, and leaky ducts can make even a correctly sized new system underperform, so the ductwork deserves a look before equipment is chosen. Where a trunk needs rework, it can usually be done from the attic without opening finished ceilings or interior walls, and a room that was never on the duct plan can take a ductless mini-split instead. The replacement estimate is free, so you know the scope before any work begins.
Does Martin County require a permit for a like-for-like residential HVAC replacement, or only for new installations?
A like-for-like swap needs a mechanical permit just as a new installation does, and the finished work gets a final inspection, which leaves an official record that it was done to code. When A/C Now replaces your system, we pull the permit, so you don't have to contact the building department yourself.
Does A/C Now LLC handle the building permit process?
Yes. We handle the entire local municipal permitting process for your new AC installation. The state of Florida requires building permits and inspections for all HVAC changeouts to ensure safety, structural wind load limits, and code compliance. We file permits in municipalities from Palm Beach Gardens and Jupiter to Stuart and Port St. Lucie, and coordinate inspections.
