As the sweltering summer heat gives way to cooler fall temperatures, it’s tempting to forget all about your air conditioner until next year. But before you flip the switch to heat, there’s one more critical task—end-of-summer maintenance.
Whether you have a central AC unit or a heat pump, giving your system a little attention now can save you money, prevent inconvenient breakdowns, and extend the life of your HVAC equipment. Here’s what you need to do for late-season AC maintenance in Bigfork, MT.
Start with the Basics: Air Filter and Coils
One of the simplest yet most effective maintenance steps is checking your air filter. If it’s dirty or clogged, it can restrict airflow, force your system to work harder, and even lead to overheating. During high-use seasons, such as summer, filters should be replaced or cleaned at least once a month. Swapping it out now ensures your system ends the season on a strong note—and if you have a heat pump, it will be ready for fall heating too.
Next, inspect your AC coils. The evaporator and condenser coils can collect dirt and dust over the summer, reducing their ability to absorb and release heat. Dirty coils mean your system is less efficient, resulting in higher energy bills and increased strain on components. While homeowners can do some light cleaning, a professional technician can provide a deeper, safer clean.
Clear the Space Around Your Outdoor Unit
Fallen leaves, overgrown grass, and wind-blown debris often start to pile up as summer winds down. All of this can block airflow around your outdoor condenser unit, reducing performance and increasing wear and tear. Clear at least two feet around the unit, remove leaves and twigs, and ensure there’s plenty of open space to allow for proper ventilation.
Did You Skip Professional Maintenance This Year?
If you didn’t schedule professional maintenance earlier in the summer, now’s the time. Preventive maintenance performed by a qualified technician can help identify small problems before they escalate into expensive repairs or total breakdowns. They’ll inspect your system, test electrical connections, lubricate moving parts, check refrigerant levels, and more. Regular maintenance isn’t just about performance—it’s also about peace of mind.
Look and Listen for Signs of Trouble
Even if your AC seems to be working fine, keep an eye (and ear) out for warning signs. Strange noises, such as rattling, buzzing, or grinding, can indicate loose parts or motor issues. Uneven cooling, weak airflow, or unexplained spikes in your energy bill can also point to underlying problems. Addressing these signs now helps prevent more serious damage later.
Heat Pump Owners: Fall Maintenance Is a Must
If your system is a heat pump, it pulls double duty—cooling your home in the summer and heating it in the winter. That means seasonal maintenance is crucial. A fall tune-up will ensure your heat pump is clean, calibrated, and ready to shift smoothly into heating mode.
