September 9, 2025

As fall starts to shift the outdoor air from warm to crisp, your heat pump needs a reset. After a long summer of cooling, it’s about to switch gears. That kind of seasonal transition is harder on the equipment than most people realize. During a well-timed maintenance visit, an HVAC technician can smooth out the change, spot any hidden issues from the cooling season, and make sure your heat pump is ready to heat efficiently. At , in O’Fallon, MO, we walk homeowners through precisely what we check, why it matters, and how it keeps your system running longer. Our goal isn’t just to fix things when they break.

Switching to Heating Mode Isn’t Automatic Your heat pump doesn’t just flip from cooling to heating like a light switch. It shifts how it moves refrigerant, how the reversing valve operates, and how the outdoor coil behaves in colder air. In the summer, the outdoor coil dumps heat.

Fall brings shifting indoor and outdoor temperatures, fluctuating humidity, and more frequent cycling as heating demands ramp up. That seasonal shift makes early fall the best time to prep your mini split for what’s coming next. As leaves fall and the air gets cooler, your outdoor unit starts working differently. Any debris near the base, like twigs or dead leaves, could obstruct airflow or trap moisture. Clearing out that area gives the system better breathing room when it needs it most....
