Heating and cooling services
Seven kinds of call. If the system has stopped, call; call for anything else.
AC repair
Capacitors, contactors, blower motors, drain lines, coils, the slow leak that needs a recharge every June. What a diagnosis should include.
AC replacement and installation
SEER2, R-454B or R-32, the ended federal credit, the mechanical permit, and the JEA, Beaches Energy, Clay Electric or FPL rule on your bill.
Heat pump and no-heat calls
January nights at 43 °F: heat strips, defrost steam that looks like smoke, a thermostat stuck in Emergency Heat, and what is normal.
Tune-up and maintenance
What a real tune-up checks (static pressure, charge, capacitor, drain), when to do it, and the JEA tune-up rebate.
Ductwork, airflow, and humidity
Attic ducts at 130 °F, undersized returns in the old grid, a house that is cool but clammy. Airflow before tonnage.
Mini-split and ductless
Garages, Florida rooms, additions, the bonus room over the garage. Which rebates include them and which do not.

What the system is up against
The climate a Jacksonville air conditioner runs in
The 1991–2020 averages for Jacksonville International Airport, and the recent records that beat them. A system here runs from April into October, and the heat pump side works most winters.
91.9 °FJuly normal high
June 89.9, July 91.9, August 90.8, September 87.2. The low stays above 73 °F in July and August, so the house never sheds its heat overnight and a weak system loses ground every day.
2025The hottest July on record
July 2025 at the airport: 98 °F or higher on more than nine days and daily records tied or broken July 26 through 29. That week is why the capacitor and drain-line calls stack up.
53 inRain a year
June 7.60 in, September 7.56, July 6.77, August 6.88: two-thirds of it in the cooling season. Humidity, not temperature, is what an oversized or leaky system fails at; the house is 76 °F and damp.
42.9 °FJanuary normal low
December 45.8, January 42.9, February 46.1. The First Coast has real winter nights; a heat pump runs its strips, and "no heat" is a January call this far north in Florida.

Whose bill is it
Four electric utilities, four rebate rules
A replacement quote on the First Coast depends on which utility sends the bill. Each has its own efficiency floor, paperwork and window; the amounts are on their pages and the contractor usually files the form.
JEA
Duval, Atlantic Beach, parts of St. Johns, Clay and Nassau
ENERGY STAR-certified central AC, heat pump or ductless mini-split; 16 SEER2 on JEA's application form (JEA's web page adds 8.0 HSPF2 for heat pumps).
application within 90 days of installation per the application form (the form and JEA's web page currently show different program years and criteria, so confirm both with JEA before counting on it); two rebates per product type per address every seven years. JEA also lists an HVAC tune-up rebate.
JEA heating and cooling rebates →Beaches Energy Services
Jacksonville Beach, Neptune Beach, Ponte Vedra Beach, Palm Valley
Air conditioner and heat pump rebates in two tiers, SEER 15 and SEER 16 or higher, for existing homes.
Forms, the invoice and the documentation within 90 days of installation; incomplete paperwork is delayed or denied. New construction does not qualify.
Beaches Energy rebates →Clay Electric Cooperative
Middleburg, Lake Asbury, parts of Fleming Island, Oakleaf and the Westside
Energy Smart bill credit for a heat pump at 15.2 SEER2 (16 SEER) or higher, 12,000 to 60,000 BTU.
Detailed invoice and the AHRI certificate, before-and-after photos, an inspection if the co-op asks, within 180 days of purchase, on an active account.
Clay Electric Energy Smart →FPL
St. Augustine, Nocatee, Yulee and mainland Nassau
An instant rebate on the invoice for a complete new system, indoor and outdoor units, at 15.2 SEER2 or higher.
Only through an FPL Participating Independent Contractor; the credit appears on their invoice, no form to send.
FPL A/C rebate →Fernandina Beach and Amelia Island are Florida Public Utilities; ask FPU what it offers before you sign. The federal Section 25C credit ended for property placed in service after December 31, 2025; that credit does not apply to a 2026 install, whatever a sales sheet still says; other programs, such as Florida's home energy rebates, have their own eligibility and are worth checking.
Three numbers behind every quote
The permit, the refrigerant, and the river
A change-out in Duval is a mechanical permit through the City; the equipment that goes in is decided in Washington; the river decides how high a flooded condenser comes back.
The permit and the Notice of Commencement
Replacing an air-conditioning system in Jacksonville is permitted work: the City says heating and air-conditioning work "must be done only by contractors and craftsmen certified in those trades and require separate permits," and the state's 2026 $7,500 permit exemption excludes mechanical work. A Notice of Commencement is required at $15,000 for mechanical work, against $5,000 for other jobs. The contractor pulls the permit on JaxEPICS under their own license; ask for the number.
City of Jacksonville Building Inspection Division, residential permitsSEER2 and the refrigerant change
The federal floor in the Southeast since 2023 is 14.3 SEER2 for a split system under 45,000 Btu/h and 14.3 SEER2 with 7.5 HSPF2 for a heat pump. New systems built since January 1, 2025 use R-454B or R-32 depending on the manufacturer, and an EPA rule effective July 27, 2026 lets contractors keep installing R-410A units built before 2025 until stocks run out. A quote should state which refrigerant the equipment uses.
DOE regional standards; EPA final rule, NAHB summaryWhere a flooded condenser comes back
Irma put the St. Johns at 5.57 feet on September 11, 2017, the highest since 1846, and Matthew sent the ocean over A1A the year before. Jacksonville's floodplain ordinance sets the design flood elevation two feet above the base flood elevation, and the building code puts replacement equipment damaged by flood at or above the required elevation. AHRI's guidance: replace flooded equipment, do not repair it.

Which electric bill decides your rebate
JEA, Beaches Energy, Clay Electric and FPL each ask for a different efficiency and a different piece of paper, and the window closes fast. The guide walks through all four, what the AHRI certificate is, and why the contractor should file it.

Questions people ask
Does replacing my AC need a permit in Jacksonville?
Yes. The City of Jacksonville lists heating and air-conditioning work as permitted work done by contractors certified in that trade, and the state's 2026 $7,500 permit exemption does not cover mechanical work. Jacksonville Beach, Atlantic Beach, Neptune Beach, St. Johns, Clay and Nassau have their own building departments. The contractor pulls it under their own license.
Can I still get a federal tax credit for a new system?
Not for a 2026 installation. The Section 25C credit applied to property placed in service through December 31, 2025. What remains is the utility rebate on your own bill: JEA, Beaches Energy, Clay Electric or FPL, each with its own efficiency floor and paperwork.
Should I add refrigerant myself?
No. Refrigerant may only be handled by an EPA-certified technician, and a recharge kit on an R-410A or R-454B system leaves a mixed charge the contractor then has to recover. A system that needs a recharge every summer has a leak; adding refrigerant is not the repair.
My heat pump is blowing cold air in January. Is it broken?
Maybe not. A heat pump defrosts itself in cold, damp weather: the outdoor fan stops, steam rises off the coil, and the indoor air goes cool for a few minutes before the strips take over. Air that stays cool for an hour, a thermostat stuck in Emergency Heat, or a breaker that trips is a call. The heat pump page has the list.
Do you serve Spanish-speaking homeowners?
The site is in English and Spanish. Whether the contractor who takes your call has Spanish-speaking staff depends on the contractor; ask when you call, and say which language you prefer.
