When your air conditioner stops working in the middle of a Northwest Florida August, it is not a minor inconvenience. It is a problem that needs a clear diagnosis and a fast, correct repair. McCombs Electrical Heating & Air handles AC repair across Milton, Pace, Pensacola, Gulf Breeze, and Cantonment, and our work is led by Josh Rogers, PE, a licensed Professional Engineer who holds Florida HVAC License RM0034309. That engineering background matters here, because an AC that has stopped working is often an electrical problem wearing an HVAC costume, and we diagnose both sides in a single visit.
Start With the Two Things You Can Check Safely
Before you call anyone, two quick checks can tell you a great deal. First, look at your thermostat. Confirm it is set to cool, the temperature is set below the current room temperature, and the batteries are not dead. A thermostat with dead batteries is one of the most common reasons a system that worked yesterday does nothing today. Second, check your electrical panel for a tripped breaker. If the breaker that serves your air handler or outdoor unit has tripped, switch it fully off and then back on one time. If it trips again immediately, stop. A breaker that trips the moment you reset it is telling you there is an electrical fault, and that is the point to call rather than keep trying.
The Most Common Reasons an AC Stops Working in August
When the thermostat and breaker are not the problem, the cause usually falls into a short list that our technicians see repeatedly during the peak of a Northwest Florida summer.
A failed capacitor is near the top. The capacitor is a small component in the outdoor unit that gives the compressor and fan motors the jolt they need to start. In a climate where the system runs seven to eight months per year, capacitors wear out faster than they do in milder markets, and August heat is often the moment a marginal capacitor finally quits.
A failed contactor is a close relative. The contactor is the electrical switch that tells the outdoor unit to turn on. When its contacts burn or stick, the outdoor unit goes silent even though the indoor fan keeps running.
A refrigerant problem is another frequent cause. A system low on refrigerant from a slow leak can lose cooling capacity until it stops cooling entirely, and a frozen evaporator coil can shut the system down completely. If you have read our guide on an AC running but not cooling, you already know how a frozen coil develops.
Finally, a clogged condensate drain can trip a safety float switch that shuts the system off on purpose to prevent water damage. This one is common in August because high humidity means the system produces a large volume of condensate every day.
Why August Is the Month Systems Quit
There is a reason the call volume climbs in August. By late summer, your system has been running almost continuously for months, and every weak component has been under sustained stress since spring. The August heat index in Milton, Pace, Pensacola, Gulf Breeze, and Cantonment pushes equipment to run at full output for longer stretches each day, and a part that was merely weak in May reaches the end of its life in August. This is also why a system that fails in August often has more than one issue. The original fault may be a worn capacitor, but the strain of running hard can reveal a second problem at the same time.
The Diagnosis That Covers Both Sides
Because an AC that has stopped working is so often an electrical fault rather than a mechanical one, the right diagnosis examines both. Most HVAC companies are licensed only for the mechanical side and have to refer the electrical questions elsewhere. McCombs Electrical Heating & Air holds both a Florida HVAC license and a Florida electrical contractor license, License EC13014513, which means our technician can test the capacitor, the contactor, the breaker, and the wiring in one visit without bringing in a second company. Josh Rogers, PE leads our team, and that engineering depth is the reason we treat an electrical symptom as an electrical question rather than guessing at it.
When to Call
If your system is completely dead, if a breaker trips again the moment you reset it, if you hear a hum from the outdoor unit but the fan is not turning, or if you see ice on the refrigerant lines, those are the signs to stop troubleshooting and call. Running a system in any of those conditions risks turning a small repair into a compressor replacement. To reach McCombs Electrical Heating & Air, call (850) 994-5467 or submit a service request through our contact form, and we will get a technician to you as soon as available. Scheduling an HVAC maintenance plan visit afterward helps catch a weak capacitor or contactor before it fails again.
Frequently Asked Questions
Why did my AC stop working overnight when it was fine yesterday?
The most common overnight failures are a dead thermostat battery, a tripped breaker, or a capacitor that finally wore out after months of summer running. A quick thermostat and breaker check rules out the simplest causes before a technician looks at the electrical components.
Is it safe to keep resetting a breaker that controls my AC?
No. If a breaker trips once, you can reset it a single time. If it trips again immediately, that indicates an electrical fault, and repeatedly resetting it can create a fire risk. That is the point to call for service.
How fast can someone come out during an August heat wave?
McCombs Electrical Heating & Air responds as quickly as available, and demand is highest during August heat. Calling early in the day improves your chances of being seen the same day (when available).
Could my AC problem actually be electrical?
Often, yes. Failed capacitors, burned contactors, and tripped breakers are electrical faults that stop an AC system. Because we hold both HVAC and electrical licenses, we diagnose both in a single visit.
An air conditioner that has stopped working in August is not a problem to wait out in Northwest Florida heat. McCombs Electrical Heating & Air serves Milton, Pace, Pensacola, Gulf Breeze, and Cantonment, and has been serving the region since 1974. Call (850) 994-5467 or submit a service request and we will diagnose the cause correctly the first time.
