When your AC stops working in Southwest Florida, you need it fixed fast. Semper Fidelis AC provides same-day AC repair service throughout Naples, Bonita Springs, Marco Island, Estero, and all of Collier and Lee Counties.
What We Repair
We diagnose and repair all major AC brands and system types β split systems, package units, mini-splits, and heat pumps. Common repairs include capacitor and contactor replacements, refrigerant leak detection and recharge, blower motor failures, compressor issues, thermostat malfunctions, and drain line clogs. Most repairs are completed the same day.
Signs Your AC Needs Repair
Florida homeowners should watch for these warning signs that your air conditioner needs professional attention before a small problem becomes a costly breakdown:
- Warm air blowing from vents β If your AC is running but not cooling, you may have a refrigerant leak, a failing compressor, or a frozen evaporator coil.
- Unusual noises β Banging, grinding, squealing, or rattling sounds indicate loose or failing components that need immediate inspection.
- High humidity indoors β Your AC should control humidity. If your home feels sticky even with the AC running, the system is not dehumidifying properly.
- Frequent short cycling β If your AC turns on and off every few minutes, it may be oversized, low on refrigerant, or have a failing capacitor.
- Skyrocketing energy bills β A sudden spike in your FPL bill without a change in usage often means your AC is working harder than it should due to a mechanical issue.
- Water leaks around the unit β A clogged condensate drain line is one of the most common AC problems in Florida and can cause water damage if left untreated.
- Ice on the unit β Ice forming on your indoor or outdoor unit is a sign of restricted airflow or low refrigerant and requires immediate shutdown and service.
If you notice any of these signs, call Semper Fidelis AC at (239) 316-8555 for a same-day diagnostic. Catching problems early saves money and prevents full system failure.

Frequently Asked Questions About AC Repair in Naples
How long does an AC repair take?
Most AC repairs in Naples take between 1 and 3 hours. Simple fixes like a capacitor replacement are typically done in under an hour. More complex repairs involving refrigerant leaks or compressor issues may take 2 to 4 hours. Our trucks are fully stocked with common parts for the most popular brands so we can complete the majority of repairs on the first visit.
Do you charge for the diagnostic visit?
Yes, we charge a diagnostic fee to inspect your system and identify the problem. This fee is applied toward the cost of the repair if you choose to proceed with us. You will always know the full cost before any work begins.
Is it better to repair or replace my AC?
A common rule of thumb is the “5,000 rule” β multiply the age of your AC by the cost of the repair. If the result exceeds $5,000, replacement is usually the smarter investment. Our technicians will give you an honest assessment of whether repair or replacement makes more financial sense for your specific situation.
Why is my AC running but not cooling?
The most common reasons an AC runs but doesn’t cool include low refrigerant due to a leak, a dirty or frozen evaporator coil, a failing capacitor, a bad contactor, or a clogged air filter restricting airflow. Call us for a same-day diagnostic at (239) 316-8555.
How often should I have my AC serviced in Naples?
In Southwest Florida, we recommend professional AC maintenance twice per year β once in the spring before peak cooling season and once in the fall. Florida’s heat, humidity, and salt air put significantly more stress on HVAC equipment than in other states. Semper Fidelis AC offers maintenance plans starting at $249/year.
Do you repair all AC brands?
Yes. Our technicians are trained and certified to repair all major AC brands including Carrier, Trane, Lennox, Rheem, Goodman, Daikin, York, American Standard, Bryant, and all other residential and commercial HVAC brands. We stock common parts for the most popular brands on our service trucks.
What warranty do you offer on AC repairs?
All parts we install carry the manufacturer’s warranty, and our labor is warranted as well. If a repair we performed fails within the warranty period, we will return and make it right at no additional charge. Ask your technician for specific warranty terms at the time of service.
