Most AC systems should be serviced once a year, ideally in the spring before the cooling season starts. Annual maintenance catches small problems before they become expensive repairs, keeps your system running efficiently, and extends its lifespan. If you have an older system or use your AC heavily, twice-yearly service might make sense. Regular maintenance typically pays for itself through lower energy bills and fewer emergency repairs.
Watch for these warning signs: your system isn’t cooling effectively, it’s making unusual noises, your energy bills have increased significantly, there’s poor airflow from vents, or the system is cycling on and off frequently. Strange smells, ice forming on the unit, or moisture where it shouldn’t be are also red flags. If you notice any of these issues, it’s worth having a technician take a look before a small problem becomes a major repair.
A well-maintained AC system usually lasts 15-20 years, though the duration varies based on usage, maintenance, and local climate conditions. Dover’s humid summers can be tough on AC equipment, making regular maintenance even more important. Signs it might be time for replacement include frequent repairs, rising energy bills, uneven cooling, or if your system is over 15 years old and needs a major repair. A good technician can help you decide whether repair or replacement makes more financial sense.
First, check your thermostat settings and make sure the system is set to cool. Check your circuit breaker to see if it’s tripped. Look at your air filter—a completely clogged filter can shut down some systems. If these basics don’t solve the problem, turn off the system and call for service. Don’t keep trying to restart it, as this can cause additional damage. Most AC failures during hot weather need professional diagnosis and repair.
Start with regular filter changes—dirty filters make your system work harder. Keep vents and registers unblocked by furniture or curtains. Set your thermostat a few degrees higher when you’re away from home. Use ceiling fans to help circulate cool air. Make sure your home is properly insulated and seal any air leaks around windows and doors. Annual professional maintenance is also essential for keeping your system running at peak efficiency.
