Florida’s intense storm season brings more than heavy rain and lightning—it also poses a serious threat to residential air conditioning systems. In Brevard County, frequent thunderstorms cause power surges and voltage fluctuations that can quietly damage sensitive HVAC electrical components. After storms, homeowners often notice systems struggling to start, making buzzing or clicking sounds, or shutting off unexpectedly. These issues are commonly linked to electrical damage caused by storm-related surges.
Power surges occur when electrical voltage spikes beyond what an AC system is designed to handle. A direct lightning strike is not required; nearby strikes or disruptions to power lines can send damaging voltage through the electrical grid. Repeated small surges, especially during outages and power restoration, steadily weaken electrical parts until failure occurs. Over time, this stress leads to costly breakdowns.
Modern air conditioning systems are particularly vulnerable because they rely heavily on electronic components. Control boards, sensors, capacitors, contactors, and microprocessors all require stable voltage to function properly. Even minor fluctuations can shorten their lifespan. Capacitors are among the most frequently damaged components, as they store and release the energy needed to start motors and compressors. When compromised, systems may hesitate or fail to start entirely.
Contactors are another common failure point. These electrical switches regulate power flow to major components. Power surges can damage their contact points or weld them together, preventing normal operation. Other at-risk parts include compressors, fan motors, thermostats, and control boards. Compressor damage is especially concerning due to its high replacement cost.
Warning signs of electrical damage often appear gradually. Homeowners may notice unusual noises, short cycling, burning odors, or thermostat displays going blank after a storm. Ignoring these symptoms can be expensive, as weakened electrical components place additional strain on the compressor and increase the risk of major system failure.
Florida Breeze Air and Heat helps homeowners recover after storms by inspecting electrical components for surge damage and wear. Prevention is equally important. Whole-house surge protectors, regular maintenance inspections, and shutting off the system during severe storms can significantly reduce risk. With proper care and prompt attention to warning signs, homeowners can protect their AC systems and stay comfortable throughout Florida’s storm season.
