How Earth City’s Climate Impacts HVAC Systems

Earth City’s location along the Missouri River exposes homes and businesses to some of the region’s toughest seasonal extremes. These conditions force heating and cooling systems to work harder, often leading to higher costs and more frequent service needs. Here are some of the most common climate impacts we see:

  • High Summer Humidity: The Missouri River Valley traps moisture, making Earth City summers especially muggy. Air conditioners run longer cycles to remove humidity, which can increase wear and energy bills.
  • Extreme Heat Waves: Temperatures in July and August regularly climb into the 90s, causing older AC units to struggle with airflow and cooling capacity. This often leads to breakdowns at the peak of the season.
  • Sudden Winter Cold Snaps: Earth City experiences sharp temperature drops in the winter, which can overwhelm furnaces and heat pumps. These rapid swings put extra stress on equipment, leading to more frequent repairs.
  • Increased Allergen Levels: With farmland and wooded areas surrounding the community, seasonal pollen and dust are common. Without proper filtration, these contaminants circulate indoors and reduce indoor air quality.
  • Floodplain Humidity Concerns: Properties near the Missouri River often face higher baseline moisture levels, which can encourage mold growth and strain dehumidifiers or air conditioning systems.

Travis , the technician, came out in very polite and professional and identified 2 problems I was experiencing with my furnace. The last few days have been very chilly. He stated what was needed and the price it would involve. With recommendations to plan on if other problems arise. He had to gather equipment needed to get the repair done he was quick and fastidious in his service and informed me when it was completed. Was very happy with the results. My furnace is running again and I’m warming back up. Thank you Stay Cool HVAC for you service.

On Jan 16, 2026 I called Stay Cool Climate Control to get a quote on replacing our old HVAC because the furnace was showing signs of imminent failure. I called the office in the morning, and Jeremy was able to come that afternoon. Jeremy looked at the old system and offered us multiple replacement choices. A few days later, after checking with 2 other companies, we concluded that Stay Cool was the best choice for us in terms of cost, efficiency, and equipment quality. We are not disappointed. Installation was scheduled for the following Tuesday. Brandon, Dalton, and Trey arrived on time early that morning, and after seeing the old system began removing it. Even though the outside temperature was in the teens and there was snow on the ground they worked tirelessly all day. By late that afternoon we had a new, highly efficient HVAC system up and running. Our thanks also go to Carter, who has answered many questions and was able to make the quick schedule possible.

HIGHLY Recommend. Our furnace quit right as a winter storm rolled in, and they sent someone out within an hour! Dalton figured out our issue and got our unit to work for just a bit longer until our replacement could be scheduled. Jake and Skylar handled our replacement. The office will send names and pictures of who is coming to your home, which made me feel very safe. Every person we encountered on the phone or in person was professional, friendly, and knew what they were doing. Pricing was fair and transparent, and they helped us get financing. Never felt rushed or pressured. A+ communication.

On time arrival to service my furnace for the winter. Travis was very courteous. He carefully reviewed his findings and answered all of my questions. As a realtor and homeowner, I strongly suggest that your HVAC system be checked, serviced and cleaned twice yearly. Use a professional like Stay Cool Climate Control.
