Spring and fall in Missouri often bring wild temperature swings—chilly mornings that demand heat followed by afternoon heat spikes requiring air conditioning. These rapid changes put significant stress on your heating and cooling system. At Survant Heating & Air Conditioning, we help homeowners keep their indoor climate comfortable and energy-efficient, no matter how unpredictable the weather gets outside. Here is how you can prepare your HVAC system for drastic temperature fluctuations.

Inspect and Change Your Air Filters
Rapid switching between heating and cooling increases airflow demands on your system. Clogged or dirty air filters restrict airflow, forcing your equipment to work twice as hard to stabilize temperatures. Check your air filter monthly during transitional seasons and replace it as soon as it looks dirty. Clean filters protect your internal components and improve overall indoor air quality.

Upgrade to a Smart or Programmable Thermostat
Constantly adjusting a manual thermostat as the temperature shifts can lead to high energy bills and unnecessary system wear. A smart thermostat automatically adjusts setpoints based on your daily routine and local forecasts. You can program gentle transitions between heating and cooling modes, preventing your system from short-cycling or overworking during sudden weather shifts.

Clear the Outdoor Unit and Vents
Ensure your outdoor AC unit or heat pump is free from debris like fallen leaves, twigs, and overgrown vegetation. Maintain at least two feet of clear space around the unit to ensure proper airflow. Indoors, make sure supply and return vents are open and unblocked by furniture or drapes, so air circulates freely throughout your home.
Schedule Preventative Maintenance
The best defense against sudden breakdown is professional maintenance. Comprehensive tune-ups catch minor issues before extreme temperature changes turn them into costly repairs.
