Common HVAC Solutions We Bring to Weldon Spring Homes

Older houses sometimes need ductwork improvements or updated systems, and newer builds benefit from zoning upgrades to better regulate temperatures.

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.

Their quote was spot on, they showed up when they said they would. Great experience. Travis was also super helpful in navigating a new furnace. We will be using them again when our other furnace finally dies. Thank you!

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.
