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 run a room-by-room Manual J load calculation 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.

When an AC system reaches the end of its life on the Treasure Coast, replacing it right is one of the highest-return home decisions you can make — a modern high-efficiency system can cut cooling bills meaningfully in a climate where the AC runs most of the year. A/C Now handles complete system replacements across Martin, St. Lucie, and northern Palm Beach counties.

The decision to replace rather than repair usually comes down to age, refrigerant, and repair cost. Systems past about 12 to 15 years, or those still running discontinued R-22, often cost more to keep alive than to replace — especially given how hard our long, humid summers push equipment. We size every replacement with a proper Manual J load calculation rather than matching the old unit's tonnage, so you get uniform cooling and real efficiency instead of an oversized system that short-cycles. High-efficiency SEER2 equipment, FPL utility rebates, and complete warranties make the upgrade practical, and we handle permitting and haul-away so the changeover is clean.

🌧️ Climate Reality Check: High Water Table & Humidity Control

Heavy summer downpours and high local water tables create extreme indoor humidity loads. We size variable-speed inverter equipment and elevated hurricane pads to keep homes dry, mold-free, and flood-protected.

Frequently Asked AC Installation Questions

Find expert answers to common questions regarding AC replacements, high-efficiency SEER2 standards, warranties, and local building permits.

A/C Now Premium AC Installation

When is it worth replacing my AC instead of repairing it?

Generally when the system is over 12 to 15 years old, runs R-22 refrigerant, or faces a major repair like a compressor or coil. In our climate the energy savings from a modern high-efficiency system often pay back a replacement faster than homeowners expect.

How much can I save with FPL rebates on a replacement?

Qualifying high-efficiency SEER2 heat pump systems may earn utility rebates and federal energy tax credits. We review current rebate programs and provide documentation for your installation.

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.
