AC Service

AC Service is the broad term for what keeps your cooling system running through Jacksonville’s long, humid season, and it includes everything from a seasonal tune-up to a full diagnostic when something fails. Homeowners call us for AC service when their system is short-cycling, making noise, or simply running but not cooling the way it should. A standard AC service visit in Jacksonville typically runs $80 to $200 for a tune-up, while most repair work lands between $150 and $650 with parts and labor included. For a full breakdown of what to check, see our AC Repair Maintenance Checklist for Jacksonville Homeowners. Brandt HVAC Co Jacksonville starts every service call with a written price, so you approve the cost before any tool comes off the truck.

Tune-Up and Safety Inspection

We check refrigerant levels, test the capacitor, clean the condenser coil, and measure the temperature drop across your evaporator. That gives us a baseline for how your system is performing. If we find a problem, you get a written quote before any repair work starts.

Diagnostic Service Call

When your AC isn’t working and you aren’t sure why, we trace the issue methodically: thermostat signal, electrical connections, refrigerant pressure, airflow, and drainage. Our technicians carry digital manifolds and clamp meters to get accurate readings quickly. You’ll know the root cause and the fix cost within the first visit.

AC Unit Repair

AC Unit Repair covers any mechanical or electrical failure inside the condensing unit sitting outside your Jacksonville home or the surrounding area, including AC Repair in Orange Park, or the air handler tucked in a closet or attic. When you need AC unit repair, something has usually failed outright: a compressor that won’t start, a fan motor that seized, a contactor that burned out, or a control board that stopped responding. Most AC unit repairs in Jacksonville fall between $150 and $650, depending on the part and how long the repair takes. Our technicians at Brandt HVAC Co Jacksonville diagnose the failure and put a written price in your hand before any repair begins.

Compressor and Fan Motor Diagnostics

A compressor or fan motor failure often mimics smaller problems, so we test amperage draw and winding resistance before condemning any component. That prevents replacing a good part when the real issue is a capacitor or relay. You pay for the repair you actually need, no guesswork.

Control Board and Wiring Repair

Jacksonville’s heat and humidity can corrode terminals and stress electrical connections over time. We inspect for burned spade connectors, pitted contactors, and frayed thermostat wiring. When a control board has failed, we verify line voltage and low-voltage signals before recommending a replacement.

AC Capacitor Replacement

AC Capacitor Replacement is one of the most common air conditioning repairs we perform in Jacksonville, and it’s usually the fix when your outdoor unit hums but the fan won’t turn. The capacitor stores the electrical jolt needed to start the compressor and fan motor, and Jacksonville’s heat shortens their lifespan significantly. A capacitor replacement in Jacksonville typically runs $150 to $400, including the part and the labor to install and test it. If it’s diagnosed early, this is a fast, affordable repair that can save you from a dead compressor down the line.

Start Capacitor and Run Capacitor

Some systems have separate start and run capacitors, while others combine both into a dual capacitor. We check the microfarad rating against the manufacturer’s specification and replace any capacitor that has drifted more than 10%. A weak capacitor forces the motor to work harder, which shortens its life.

Why Summer Brings Capacitor Failures

North Florida summer heat pushes your AC to run longer cycles, and that constant electrical load degrades the dielectric material inside capacitors. We keep common capacitor sizes on our trucks, so many Jacksonville capacitor replacements are completed in a single visit. The repair comes with a written guarantee under our 365-Day Done Right Promise.

AC Recharge

AC Recharge is the process of refilling the refrigerant, a fluid that moves heat out of your Jacksonville home. If your system is low on refrigerant, it’s not because the fluid “wears out” over time; a low reading almost always signals a leak somewhere in the sealed system. A straightforward AC recharge in Jacksonville generally runs $150 to $500, depending on the refrigerant type and the amount needed. At Brandt HVAC Co Jacksonville, we don’t just top off the system and leave; we run a leak search so you’re not paying for the same recharge again next season.

Refrigerant Level Check

We connect digital gauges and compare your system’s high and low side pressures against what the manufacturer specifies for current outdoor temperature. That tells us exactly how much refrigerant is missing. We never add refrigerant without first confirming the system isn’t dangerously overcharged or contaminated.

Leak Detection and Repair

Using an electronic leak detector or UV dye, we trace the line set, evaporator coil, and condenser coil for the source of the leak. Small leaks at Schrader valves or braze joints are often repairable the same day. If the leak is in an older evaporator coil, we’ll show you the repair cost alongside a replacement price so you can make an informed choice.

Emergency AC Repair

Emergency AC Repair is for the moments when your system dies on a 95-degree Jacksonville afternoon or a humid night when no one in the house can sleep. Brandt HVAC Co Jacksonville takes emergency calls around the clock, and a live person answers every time, including weekends and holidays. Emergency AC repairs in Jacksonville typically run $150 to $650, and we do not charge overtime markups for nights or weekends. Our technicians will be at your door as soon as the calendar allows, and you’ll know who is coming before they arrive.

After-Hours Response

When you call at 2 a.m. because your AC just died over a sleeping baby’s room, you won’t reach an answering service. A real, local dispatcher picks up, asks about your system, and schedules the soonest possible appointment. We dispatch from our Jacksonville base, so drive times stay as short as possible.

What Counts as an Emergency

Hot air blowing, a burning smell, water pouring from the unit, or a total system failure during dangerous heat all count. If you’re unsure, call us anyway and we’ll help you figure out over the phone whether it can wait for a standard visit or needs immediate attention. Either way, you’ll get an honest recommendation, not a push to spend money.

AC Not Blowing Cold Air

AC Not Blowing Cold Air is the single most frequent complaint we hear from Jacksonville homeowners, and its causes range from a dirty air filter to a failing compressor. When your AC is not blowing cold air, the first thing we check is airflow, then refrigerant, then the compressor and electrical controls. Most repairs for a system that is running but not cooling in Jacksonville fall between $150 and $650. Brandt HVAC Co Jacksonville diagnoses every one of these calls with a systematic process so you don’t pay for parts that won’t solve the problem.

Airflow Problems That Mimic Refrigerant Issues

A clogged filter or a collapsed duct can make your AC behave like it’s low on refrigerant: long run times, weak cooling, and frozen coils. We check static pressure and temperature drop before touching the refrigerant system. Replacing a filter or clearing a blower wheel costs a fraction of a recharge and often fixes the symptom completely.

Refrigerant and Compressor Failure

If airflow is good and the system is still not cooling, we look at refrigerant pressure and compressor function. A system running low on refrigerant will blow lukewarm air, and the evaporator coil may ice up. Our leak search and compressor diagnostics are included in the service call, so you leave with answers, not guesses.

Brands We Service

We work on Trane units regularly across Jacksonville, and we’re familiar with their variable-speed compressor setups and communicating thermostats. When a Trane system throws a fault code, we use that code plus live pressure and electrical readings to pinpoint the failing component, not a parts cannon approach.

We also repair Lennox, Goodman, and Rheem systems. Lennox equipment often uses proprietary control boards, and we stock or can quickly source their most common replacement parts. Goodman units are popular in Jacksonville for their affordability, and we know the weak points: capacitors, contactors, and evaporator coils. Rheem’s scroll compressors are reliable, but we’ve replaced enough outdoor fan motors and defrost boards to diagnose them fast. Whether you have one of these brands or any other make, we can help.

Signs You Need a Pro Right Now

• The air is warm or lukewarm. If your vents are blowing air that feels like room temperature, the compressor may be running without refrigerant, or the outdoor unit may not be running at all. This won’t fix itself, and running the system this way can damage the compressor.
• The outdoor unit is making a loud buzzing or grinding noise. A buzz usually means a failed capacitor or contactor, while grinding suggests a motor bearing. Either way, shut the system down at the thermostat and call us before the damage spreads.
• Ice is visible on the copper lines or evaporator coil. A frozen coil usually means low airflow or low refrigerant, not that your AC is “working too well.” Continuing to run it can send liquid refrigerant back to the compressor and destroy it.
• Water is pooling around the indoor unit or soaking the air filter. A clogged condensate drain can overflow into your ceiling or floor, causing water damage far more expensive than a drain cleaning. Shut the system off and give us a call.
• The system is short-cycling or running nearly nonstop. If your AC turns on and off every few minutes, it’s overheating or hitting an internal safety. If it runs all day without reaching the set temperature, something is seriously wrong, and your summer electric bill will show it. Both patterns deserve a diagnostic visit.

Our Process, Step by Step

1. 1
   You call and talk to a live person. No recordings, no “press 2 for service.” We ask basic questions about your system and what it’s doing, then schedule a visit, often the same day. Before the technician leaves our shop, you’ll receive their name and photo by text or email.
2. 2
   The technician arrives and shows a photo ID badge. They’ll knock, introduce themselves, and confirm the name matches what you were sent. This is the Threshold Verified standard, and if anyone ever shows up who you were not told to expect, that visit is on us.
3. 3
   We diagnose the system and give you a written price. Using digital manifold gauges, clamp meters, and temperature probes, we trace the problem to its source. Before any repair work begins, you get a written quote showing parts, labor, and the total. You approve it, or we don’t proceed.
4. 4
   We complete the repair and test the system. After the repair, we measure temperature drop, check refrigerant pressures, and verify the system cycles correctly. You’ll see the results before we leave. Every repair includes a written guarantee that says exactly what it covers and for how long.
5. 5
   We follow up with a written record. You’ll have documentation of what was found, what was repaired, and what we recommend for future maintenance. If anything fails inside the guarantee period, a return visit is free under our 365-Day Done Right Promise.
