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
Ductless mini-splits solve the problems ductwork cannot — cooling a garage, a converted addition, a sunroom, or an older Treasure Coast home that never had ducts, all without the loss and expense of running new duct runs. A/C Now installs and services ductless systems across Martin, St. Lucie, and northern Palm Beach counties.
A mini-split delivers efficient, zoned comfort by mounting a slim indoor head where you need it and linking it to a compact outdoor unit through a small line-set — no bulky ductwork required. That makes them ideal for additions, garages, workshops, in-law suites, and rooms that never cool evenly on a central system, and their inverter compressors run quietly and sip power compared to window units. We size each system to the space, place the indoor heads for clean airflow and appearance, and confirm the electrical supply and mounting are right before we start, so you get whisper-quiet, independent temperature control exactly where you want it.
One thing worth knowing: nearly every ductless system we install is a heat pump, so the same head that cools a garage in August reverses to warm it on the January mornings when the Treasure Coast drops into the forties. There is no separate heater to buy, wire or find room for.
HVAC Equipment & Environmental Factors on the Treasure Coast & Palm Beaches
A/C Now installs heating and cooling systems throughout Florida's Treasure Coast, where humid subtropical conditions, seasonal storms, and coastal exposure shape what a good installation needs to accomplish.
Installations are sized to each individual home, drainage/condensate planning for high rainfall, and equipment placement considering storm exposure — no 'typical' Treasure Coast home.
🌧️ 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.
Frequently Asked AC Installation Questions
Common questions about AC replacement, SEER2, warranties and permits.
What makes installation here different from elsewhere in the country?
Near-constant humidity, heavy seasonal rainfall, and hurricane exposure all affect sizing, condensate management, and mounting.
Do you handle both older homes and new construction?
Yes — older homes need closer attention to ductwork and insulation, and newer construction to precise sizing.
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.
Where do ductless mini-splits make the most sense?
Anywhere ductwork is impractical or a room needs its own control — garages, additions, sunrooms, workshops, in-law suites, and older homes without ducts. They are also great for a hot room a central system never quite reaches.
Are ductless mini-splits energy efficient?
Very. Their inverter compressors ramp up and down to match the load instead of cycling full-on and off, and because they cool only the zones you are using, they avoid the duct losses of a central system — which adds up to lower bills in our long cooling season.
