Common HVAC Problems We Address in Hazelwood

Hazelwood’s location near Lambert Airport and the busy I-270 corridor means homes experience unique comfort challenges throughout the year. Summers are hot and humid, winters bring bitter cold, and older neighborhoods often face added strain on their systems. Stay Cool Climate Control provides HVAC services in Hazelwood, MO that solve the problems local families deal with most.

  • High Summer Humidity: The heavy St. Louis County air makes cooling less effective and harder on AC units. We provide dehumidifiers and AC tune-ups to keep homes cool and efficient.
  • Cold Winter Nights: Hazelwood furnaces often run nonstop in January and February, which can lead to breakdowns. Seasonal maintenance ensures systems stay dependable when temperatures drop.
  • Air Quality Concerns: Homes near major roads like Lindbergh Boulevard and I-270 deal with more dust and pollutants. Advanced filters and UV sanitizers help improve indoor air quality.
  • Older HVAC Systems: Many Hazelwood houses built in the mid-20th century still rely on outdated equipment. We offer replacements and upgrades that improve efficiency and comfort.
  • Uneven Heating and Cooling: Split-level and two-story homes often have hot and cold spots. Zoning systems and ductwork improvements bring balanced comfort to every room.

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.
