Living in St. Louis means embracing dramatic seasonal shifts. Sweltering summers, crisp falls, icy winters, and blooming springs—it’s part of what makes our region special. But with those changes come demands on your HVAC system. As the seasons transition, your heating and cooling systems must adapt quickly and reliably. Preparing your home in advance isn’t just about comfort—it’s about efficiency, safety, and long-term savings.
In this comprehensive guide, we’ll explore how to prepare your home for HVAC transitions throughout the year. Whether you’re gearing up for summer heat or winter chills, Rick Rasch Heating & Cooling has the expert advice you need to stay comfortable and avoid costly emergencies.
Why Seasonal HVAC Prep Matters in St. Louis
Missouri’s climate isn’t known for moderation. With temperatures ranging from single digits in winter to triple digits in summer, your HVAC system works hard. Seasonal preparation ensures:
- Peak system performance
- Lower utility bills
- Reduced risk of breakdowns
- Extended equipment lifespan
- Improved indoor air quality
Skipping maintenance, on the other hand, can result in expensive emergency calls, health risks, and long-term damage to your HVAC system.
Spring Checklist: Waking Up the Cooling System
As the snow melts and tulips bloom, it’s time to get your air conditioner ready.
- Clean or Replace Filters
Dirty filters restrict airflow, reduce efficiency, and recirculate dust. Replace them every 1–3 months. - Inspect the Outdoor Unit
Clear away debris, leaves, and branches. Check for bent fins or signs of nesting animals. - Check Thermostat Settings
Set your thermostat to “cool” mode and run a test cycle. If your thermostat is outdated, consider upgrading to a smart model. - Book a Spring AC Tune-Up
Rick Rasch Heating & Cooling offers comprehensive spring tune-ups, including refrigerant level checks, coil cleaning, and motor inspections.
Pro Tip: Enroll in a Preventive Maintenance Agreement (PMA) with Rick Rasch to stay ahead of seasonal changes.
Summer Readiness: Surviving the Heat
Once the dog days of summer arrive, your AC is your best friend. Make sure it’s up to the task.
- Check for Hot Spots
Walk through your home. If certain rooms are hotter, you may have a ductwork issue or poor airflow. - Keep Curtains Closed During Peak Hours
Block direct sunlight to help maintain cooler indoor temps. - Avoid Thermostat Tampering
Constantly changing settings stresses your system. Use programmable settings or a smart thermostat. - Listen for Odd Noises
Grinding, squealing, or buzzing sounds can indicate trouble. Call Rick Rasch immediately if you hear these.
Fall Preparation: Shifting into Heating Mode
As autumn paints the trees in brilliant oranges and reds, it’s time to switch gears.
- Test the Furnace Early
Don’t wait for a freezing night. Test your furnace in early fall to catch any issues before temperatures drop. - Clean Air Vents and Ducts
Dust, allergens, and pet hair accumulate over time. Clean vents and consider professional duct cleaning every few years. - Inspect the Pilot Light or Ignitor
Ensure your furnace ignites properly. Delayed starts or frequent cycling can signal problems. - Schedule a Furnace Tune-Up
Rick Rasch’s technicians perform 20+ point inspections to ensure your system is safe and efficient.
Don’t Forget: This is the ideal time to review your carbon monoxide detectors!
Winter Survival: Heating Reliability in the Coldest Months
With icy winds blowing off the Mississippi, your home becomes your fortress. Make sure the heating system can stand guard.
- Keep Vents Unblocked
Furniture or curtains blocking vents can reduce heating effectiveness and strain your system. - Monitor Your Energy Bill
Unexpected increases may signal that your furnace is working harder than it should. - Humidifier Maintenance
Dry air in winter can lead to health issues. If you have a whole-house humidifier, clean and refill it regularly. - Prepare for Power Outages
Invest in space heaters, blankets, and emergency kits in case of winter storms.
