A new AC system is one of the largest investments you'll make in your home. In Jacksonville's subtropical climate, your air conditioner runs 2,500+ hours per year — more than almost any other appliance. Choosing the right system, sized correctly and installed properly, determines your comfort, your energy bills, and the lifespan of the equipment for the next 15 to 20 years. Cool & Cozy takes this decision seriously, and we make sure you have all the information you need to choose confidently.

When Should You Replace Your AC Instead of Repairing It?

Consider replacing your AC system if it is 12 or more years old, requires a repair costing more than 50% of a new system's price, uses R-22 (Freon) refrigerant which is no longer manufactured, needs repairs more than twice per year, or has a SEER rating below 13 (significantly less efficient than modern systems rated SEER2 14.3 or higher). If your system is under 10 years old and the repair is a one-time fix under $500, repair is almost always the better financial decision.

Consider Replacement When…

  • Your system is 12–15+ years old and showing increasing repair frequency
  • The repair cost exceeds 50% of what a new system would cost
  • Your system uses R-22 (Freon) — phased out by EPA mandate, replacement refrigerant is increasingly expensive and scarce
  • You've needed 2 or more repairs in the past 12 months
  • Your system's SEER rating is below 13 (modern systems are SEER2 14.3–22+, saving 25–50% on energy costs)
  • Your JEA electric bills have been rising despite normal usage patterns
  • Your system no longer cools your home evenly — some rooms are always warm
  • You're renovating or adding square footage that exceeds your current system's capacity

Repair May Be the Better Choice If…

  • Your system is under 10 years old and the repair is a one-time component failure
  • The repair cost is under $500 and your system has been reliable otherwise
  • Your system uses R-410A refrigerant (still available and reasonably priced)
  • The issue is limited to one component (capacitor, contactor, thermostat) and the rest of the system is sound
  • A technician has confirmed the compressor, coils, and major components have substantial remaining life

Not sure where you fall? Our technicians will inspect your system, diagnose the issue, and give you an honest recommendation. If repair makes more sense, we'll repair it. We never push a $6,000 installation when a $250 capacitor replacement solves the problem. Learn more about AC repair options →

What to Expect During Your AC Installation

A six-step process built to remove the guesswork from a major home investment.

  1. 1

    Free In-Home Estimate

    We visit your home to inspect your current system, measure your space, evaluate ductwork condition, and perform a cooling load calculation. We discuss your comfort goals, budget, and any specific concerns (like rooms that never cool properly, humidity issues, or noise). You receive a written estimate with equipment options, efficiency ratings, and total installed pricing — no hidden fees.

  2. 2

    System Selection & Sizing

    Based on the load calculation, we recommend 2–3 equipment options at different price points and efficiency levels. We explain the differences in plain language: what you get for the extra investment, how much you'll save on energy bills, and what the warranty covers. For property managers, we discuss standardization benefits across your portfolio. You choose the system that fits your budget and goals.

  3. 3

    Pre-Installation Preparation

    We order your equipment and schedule installation day. Before arrival, we confirm: clear access paths to the indoor air handler and outdoor unit location, any permits required by Duval County or your HOA, and estimated completion timeline. Most residential installations are completed in one day (6–8 hours). Larger or more complex systems may take 2 days.

  4. 4

    Professional Installation

    Our licensed technicians remove the old system (including proper refrigerant recovery per EPA regulations), install the new outdoor condenser and indoor air handler, connect refrigerant lines, wire electrical connections, and integrate with your ductwork. If duct modifications are needed for optimal airflow, we handle those as part of the project. We follow Florida Building Code requirements including hurricane tie-downs for outdoor equipment.

  5. 5

    Testing & Commissioning

    After installation, we run a comprehensive startup: verify refrigerant charge, test airflow at every supply and return vent, measure temperature splits (supply air should be 16–22°F cooler than return air), calibrate the thermostat, test all operating modes, and verify the condensate drain is flowing properly. We don't leave until the system is performing to specification.

  6. 6

    Walkthrough & Warranty

    We walk you through your new system: how to set the thermostat, recommended filter type and change schedule, what normal operating sounds are vs. anything to call about, and how your warranty works. We register the manufacturer warranty on your behalf, provide our labor warranty documentation, and schedule your first maintenance visit. We clean up our work area completely.

AC System Types We Install in Jacksonville

The right system depends on your home's layout, ductwork, and how you use cooling year-round.

Central Air Split System

The most common residential AC type in Jacksonville.

A split system has two main components: an outdoor condenser unit and an indoor air handler connected by refrigerant lines. It's the standard for most Jacksonville single-family homes. Modern split systems offer SEER2 ratings from 14.3 (minimum code-compliant) to 22+ (premium variable-speed units). Cool & Cozy installs split systems from all major manufacturers and sizes them using Manual J calculations specific to your home's layout, insulation, and Jacksonville's humidity load.

Best for: Single-family homes with existing ductwork, whole-home cooling.

Ductless Mini-Split System

Zone cooling without ductwork.

Ductless mini-splits mount directly on the wall or ceiling and cool individual rooms or zones without ductwork. They're ideal for room additions, converted garages, sunrooms, or older Jacksonville homes that were never built with ductwork. Multi-zone systems can cool 2–8 rooms from a single outdoor unit. Mini-splits are extremely energy-efficient (SEER2 ratings up to 33+) and provide both cooling and heating. They're also an excellent solution for property managers adding climate control to units that lack central air.

Best for: Room additions, homes without ductwork, zone control, property management conversions.

Heat Pump System

Cooling and heating in one system.

A heat pump operates like a central AC in summer but reverses the cycle in winter to provide heating. In Jacksonville's mild winters (average low around 42°F in January), a heat pump eliminates the need for a separate furnace or electric heating strips. Modern heat pumps are highly efficient and qualify for federal energy tax credits. For Northeast Florida, a heat pump is often the most cost-effective single-system solution for year-round comfort.

Best for: Homeowners wanting year-round comfort from one system, energy-conscious buyers.

Package Unit

All-in-one outdoor system.

A package unit combines the condenser, compressor, and air handler into a single outdoor cabinet, typically installed on a concrete slab beside or behind the home. It's common in manufactured homes, smaller homes without indoor closet space for an air handler, and some commercial applications. Package units are available in AC-only, heat pump, and dual-fuel (heat pump + gas furnace) configurations.

Best for: Manufactured homes, limited indoor space, some commercial applications.

Why Proper Sizing Matters in Jacksonville

An AC system that is too small will run constantly, never reaching your desired temperature, while consuming maximum energy. A system that is too large will short-cycle — turning on and off every few minutes — which fails to remove humidity from the air (a critical problem in Jacksonville's 70–90% relative humidity) and causes uneven temperatures throughout the home.

Cool & Cozy performs a Manual J cooling load calculation for every installation. This industry-standard calculation accounts for your home's square footage, ceiling height, insulation quality, window count and orientation, roof type and color, number of occupants, and Jacksonville's specific design conditions (outdoor dry-bulb 95°F, coincident wet-bulb 77°F). The result tells us exactly how many BTUs and tons of cooling your home requires — no guessing, no rules of thumb like "one ton per 500 square feet" that ignore humidity and building construction.

SEER2 Efficiency Ratings — What You Need to Know

As of January 2023, the HVAC industry transitioned from SEER to SEER2, a more accurate testing standard that typically produces lower numbers for the same equipment. In Florida (Southeast region), the minimum efficiency requirement is SEER2 14.3 for split systems and SEER2 13.4 for package units. Higher-efficiency systems cost more upfront but save significantly on monthly energy bills — especially in Jacksonville where your AC runs 2,500+ hours per year.

For a detailed explanation of SEER2 ratings and how to calculate energy savings, see our guide: SEER Ratings Explained.

Top AC Brands Available for Your Jacksonville Installation

We install and warranty equipment from every major manufacturer.

  • Carrier
  • Trane
  • Lennox
  • Rheem
  • Goodman
  • Daikin
  • York
  • Bryant
  • Amana

When we recommend a Carrier over a Goodman or a Daikin over a Trane, it's because we genuinely believe it's the right system for your specific situation. We install and warranty every brand we carry with the same commitment to quality.

How Much Does a New AC System Cost in Jacksonville?

A new AC system in Jacksonville typically costs between $4,500 and $12,000+ fully installed, depending on system type, size (tonnage), efficiency rating (SEER2), brand, and the complexity of the installation. A standard 3-ton, 14.3 SEER2 split system for a typical 1,500–2,000 square foot Jacksonville home generally falls in the $5,000–$7,500 range installed. Higher-efficiency systems, heat pumps, multi-zone ductless installations, and projects requiring ductwork modifications fall toward the upper end.

System Type Typical Range Notes
Standard Split System (14.3 SEER2) $4,500 – $7,500 Most common residential replacement in Jacksonville. Includes outdoor condenser + indoor air handler + labor.
Mid-Efficiency Split (16–18 SEER2) $6,500 – $9,500 Two-stage compressor, better humidity control. Saves 15–25% on energy vs. base model.
Premium Variable-Speed (20+ SEER2) $9,000 – $14,000+ Inverter-driven, whisper-quiet, maximum efficiency. Best for high-use homes or buyers prioritizing long-term savings.
Ductless Mini-Split (single zone) $3,000 – $5,000 One indoor head + outdoor unit. Ideal for room additions, garages, sunrooms.
Ductless Multi-Zone (2–4 zones) $6,000 – $12,000 Multiple indoor heads, one outdoor unit. Per-zone control. Great for homes without ductwork.
Heat Pump System $5,500 – $10,000 Cooling + heating in one system. Eligible for federal energy tax credits. Ideal for Jacksonville's mild winters.

Factors That Affect Installation Cost

  • System size (tonnage) — A 2-ton system costs less than a 5-ton system. Sizing is determined by the Manual J load calculation, not by square footage alone.
  • Efficiency rating (SEER2) — Higher SEER2 = higher equipment cost but lower monthly energy bills. In Jacksonville's climate, the payback period on a high-efficiency system is typically 3–6 years through energy savings.
  • Equipment brand — Premium brands (Carrier, Trane, Lennox) cost more than value brands (Goodman, Amana). Both categories offer reliable equipment — the difference is often in noise levels, warranty length, and advanced features.
  • Ductwork condition — If existing ductwork is damaged, undersized, or leaking, it must be repaired or modified to support the new system. This can add $1,000–$3,000 to the project.
  • Installation complexity — Attic installations, tight mechanical closets, long refrigerant line runs, and code upgrades (electrical panel, disconnect, pad) affect labor time and cost.
  • Permits — Duval County requires permits for HVAC installations. Cool & Cozy handles all permit applications and inspections as part of the project.

Frequently Asked Questions About AC Installation

Most standard residential AC installations — replacing an existing system with a similar type and size — are completed in a single day, typically 6 to 8 hours. The process includes removing the old equipment, installing the new outdoor condenser and indoor air handler, connecting refrigerant and electrical lines, and performing a full startup and testing sequence. If the project requires ductwork modifications, electrical panel upgrades, or a change in system type (for example, adding a ductless system to a home that previously had central air), the installation may take 1.5 to 2 days. Cool & Cozy provides a specific timeline estimate during your free in-home consultation.

The correct system size depends on more than just your home's square footage. Cool & Cozy performs a Manual J cooling load calculation that factors in your home's total square footage, ceiling height, insulation quality, number and orientation of windows, roof type and color, occupancy, and Jacksonville's specific design conditions including sustained high humidity. A system that is too small will run constantly without reaching your desired temperature, while an oversized system will short-cycle, fail to remove humidity, and cause uneven cooling. In Jacksonville, humidity removal is just as important as temperature reduction. Proper sizing ensures both.

Yes. Duval County requires a mechanical permit for most HVAC installations and replacements. Cool & Cozy handles all permit applications and coordinates the required post-installation inspection as part of your project — you do not need to contact the county directly. Permits ensure the work meets Florida Building Code requirements for safety, including proper electrical connections, hurricane tie-downs for outdoor equipment, and condensate drain compliance. The permit cost is included in your installation quote.

Cool & Cozy removes your old system as part of the installation. The old equipment is properly disposed of, including EPA-mandated recovery of any remaining refrigerant (it is illegal to vent refrigerant into the atmosphere). We haul away the old condenser, air handler, and any replaced ductwork or components. You do not need to arrange separate disposal. The removal and disposal cost is included in your installation quote.

Yes. Cool & Cozy offers financing options through approved lending partners with competitive interest rates and promotional offers including 0% APR for qualified buyers. The application process takes minutes and can be completed during your in-home estimate. Monthly payments allow you to invest in a higher-efficiency system that saves more on energy bills without a large upfront payment. Visit our financing page for current offers and details.

New AC systems come with two warranties: the manufacturer's equipment warranty and Cool & Cozy's labor warranty. Manufacturer warranties typically cover major components (compressor, coils, heat exchanger) for 5 to 10 years, with extended coverage available on select models when registered within 60 days of installation. Cool & Cozy registers your warranty on your behalf and provides our own labor warranty covering installation workmanship. We provide all warranty documentation at the project walkthrough and remain your ongoing service partner for any warranty claims.
