Climate challenges faced by St. Louis homeowners throw some unique considerations into the heating and cooling systems throughout the year. From summer heat that often feels like 90°F to freezing temperatures of winter, an HVAC system must operate reliably in these conditions. To maximize the systems with minimal unscheduled repair work, St. Louis homeowners get the following advice regarding maintenance.
Seasonal Maintenance Priorities

St. Louis-Specific HVAC Considerations
The Midwest climate presents unique challenges for HVAC equipment:
Humidity Management: St. Louis’s high humidity levels mean your air conditioning system must work harder to remove moisture from indoor air. Consider supplementing with dedicated dehumidification systems during peak summer months.
Temperature Fluctuations: The region’s rapid weather changes mean systems must transition between heating and cooling more frequently than in other regions. This puts additional wear on components and increases maintenance requirements.
Allergen Control: St. Louis ranks among the worst cities for allergies. Regular ductwork cleaning and advanced air filtration systems can significantly improve indoor air quality during peak pollen seasons.
