Whether your AC system has reached the end of its life or you’re upgrading for better efficiency, Semper Fidelis AC handles full system installations throughout Naples and all of Collier and Lee Counties. Every installation includes permitting, county inspection, and manufacturer warranty registration.
What We Install
We install split systems, package units, mini-split systems, and heat pumps from top brands including Daikin, Allied, and RunTru by Trane. We offer three pricing tiers β Good, Better, and Best β so you can choose the right balance of budget and performance for your home. All new systems use the latest A2L low-GWP refrigerants (such as R-454B or R-32), which are now required under federal regulations replacing the older R-410A standard.
Signs It’s Time to Replace Your AC
In Southwest Florida, air conditioners work harder and run longer than in almost any other part of the country. Here are the key indicators that it’s time to consider a full system replacement rather than another repair:
- Age of the system β If your AC is over 10-12 years old, it is nearing the end of its reliable lifespan in Florida’s harsh climate.
- Frequent, costly repairs β If you are constantly calling for service, or if a single repair costs more than half the value of a new system (the “5,000 rule”), replacement is the smarter financial choice.
- Rising energy bills β As AC units age, they lose efficiency. A sudden or steady increase in your cooling costs often means the system is working too hard to maintain temperature.
- Uneven cooling β If some rooms are freezing while others are hot and humid, your aging system may no longer be able to push air effectively throughout the house.
- Uses R-22 refrigerant β If your system still uses Freon (R-22), it is obsolete. R-22 is no longer manufactured, making repairs extremely expensive and full replacement necessary when leaks occur.
Our AC Installation Process
We believe in doing the job right the first time. Our installation process is designed to protect your home, ensure maximum system efficiency, and comply with all local building codes:
- In-Home Assessment & Load Calculation β We never guess on sizing. We perform a Manual J load calculation to determine the exact cooling capacity your specific home requires.
- Transparent Options β We present you with Good, Better, and Best equipment options, explaining the SEER2 ratings, warranty terms, and total upfront costs for each.
- Permitting β We handle all paperwork. We pull the required mechanical permit from Collier or Lee County before work begins.
- Professional Installation β Most installations take one full day. We remove and properly dispose of your old equipment, install the new air handler and condenser, flush the drain lines, and install a new thermostat if needed.
- Testing & Commissioning β We test the system across all modes, verify proper refrigerant charge, check airflow, and ensure the system is operating at peak efficiency.
- County Inspection β We schedule the final county inspection to close out the permit, ensuring the work meets all Florida Building Code requirements.
How Much Does a New AC System Cost in Naples?
A new AC system in Naples typically costs between $5,500 and $15,000+ installed, depending on the size of your home, the equipment brand, and the SEER2 efficiency rating. We provide free in-home estimates with transparent pricing β no hidden fees or inflated quotes. Financing options are available to help make your investment manageable with comfortable monthly payments.
Permits and Inspections
Florida law requires a mechanical permit for all HVAC installations. For system replacements over $15,000, a notarized Notice of Commencement (NOC) must be recorded before work begins.

Frequently Asked Questions About AC Installation
How long does an AC installation take?
A standard residential AC replacement in Naples takes one full day (typically 4 to 8 hours). We arrive in the morning, remove the old equipment, install the new system, and have your home cooling again by the afternoon.
What is a SEER2 rating?
SEER2 stands for Seasonal Energy Efficiency Ratio 2. It measures how efficiently an air conditioner cools your home over a typical cooling season. The higher the SEER2 rating, the more energy-efficient the system is, which translates to lower monthly electricity bills. In Florida, the minimum required rating for new installations is 14.3 SEER2, though many homeowners opt for 16 to 18 SEER2 systems for better long-term savings.
Do you offer financing for new AC systems?
Yes, we offer flexible financing options for new HVAC installations. We understand that replacing an AC is a major unexpected expense for many homeowners. Our financing plans allow you to get the high-efficiency system you need now while paying for it over time.
What warranty comes with a new AC installation?
Most new AC systems we install come with a 10-year manufacturer’s warranty on parts and the compressor (when registered). We handle the warranty registration process for you to ensure your coverage is fully activated. We also provide a labor warranty on our installation work for your peace of mind.
