Stay Cool Climate Control

Effective Air Sealing Services

Drafty rooms, uneven temperatures, and high energy bills can leave your home feeling less comfortable and more expensive to maintain. These issues are often caused by small cracks, gaps, and leaks in walls, ceilings, and attics that allow conditioned air to escape. Over time, this air loss forces your HVAC system to work harder, driving up costs and wearing out your equipment faster.

Stay Cool Climate Control provides professional air sealing services in O’Fallon, MO, and the Greater St. Charles County area to stop leaks at the source. Our team identifies problem areas with precision and applies proven techniques to seal them, reducing wasted energy and improving year-round comfort. With tailored solutions and a commitment to lasting results, we help homeowners enjoy lower utility bills, better HVAC performance, and a healthier indoor environment. Call today to schedule your air sealing service and start saving energy with a more comfortable home.

What Is Air Sealing and Why Is It Important?

Air sealing is the process of closing gaps, cracks, and leaks throughout your home that allow conditioned air to escape and outside air to enter. These leaks are often found in attics, basements, around windows and doors, and even near ductwork. By addressing these hidden problem areas, air sealing services improve your home’s overall energy efficiency and reduce strain on your heating and cooling system.

Proper air sealing saves money on utility bills and creates a healthier and more comfortable indoor environment. With fewer drafts and better temperature control, your home feels consistently comfortable in every season. It also helps reduce indoor pollutants, allergens, and humidity issues that can sneak in through leaks. In short, air sealing is one of the most cost-effective ways to upgrade both your comfort and your home’s efficiency.

Our Comprehensive Air Sealing Process

Stay Cool Climate Control provides detailed air sealing services that eliminate drafts, improve efficiency, and make your home more comfortable year-round. Many homeowners first discover the need for air sealing during an energy audit, which pinpoints exactly where leaks are occurring. Each service we provide is performed with precision and tailored to your home’s unique needs. Here’s an overview of what we offer:

Home Energy Inspections

Our home energy inspections are the first step in identifying where your home is losing conditioned air. Using advanced testing methods, we locate gaps and leaks that contribute to higher energy bills and reduced comfort. This evaluation helps us create a customized plan for sealing your home effectively. With an accurate assessment, you’ll know exactly where improvements are needed.

Attic and Basement Air Sealing

Attics and basements are two of the most common areas for air leakage. Our attic and basement air sealing servicesaddress these problem spots with professional-grade materials that stop drafts and reduce energy loss. Sealing these areas helps your HVAC system maintain consistent temperatures throughout the home. The result is a more efficient system and a more comfortable living environment.

Ductwork Air Sealing

Leaky ducts can waste a significant amount of conditioned air before it ever reaches your living spaces. Our ductwork air sealing services restore proper airflow and reduce the workload on your heating and cooling system. By sealing leaks in your duct system, we help improve efficiency, comfort, and indoor air quality. A well-sealed duct system ensures every room gets the air it needs.

Whole-Home Air Sealing

For maximum results, we offer whole-home air sealing services that cover every part of your house. From windows and doors to walls and ceilings, we seal leaks that contribute to drafts and wasted energy. This service is designed to create an efficient, consistent environment where your HVAC system can work at its best. With whole-home air sealing, you’ll enjoy lower energy bills and long-term comfort.

Benefits of Air Sealing Services

Investing in professional air sealing services offers advantages that go far beyond stopping drafts. By addressing hidden leaks throughout your home, air sealing helps your HVAC system operate more efficiently, lowers monthly utility bills, and creates a consistently comfortable living environment. It also contributes to healthier indoor air by reducing the entry of dust, allergens, and pollutants.

Dalton came out for our annual furnace maintenance and did amazing!

Called 3 companies early in the morning. Stay Cool was able for me to take pics of the area while other companies wanted to come out 3+ days later to look while we had no hot water. Stay Cool was able to come out the same day which was a huge plus for us since we had not had hot water for 2 days already. Their price was also $350 and $700 cheaper than 2 other companies I have had in the past. Travis and Carter showed up on time and walked me through the tearing out and install of the new heater. They were courteous of their wet shoes with slips if they had to go to their truck outside when tearing out the old water heater. Carter, with our older heavy door headed to the garage it doesn't take much to close it. Please be easier in the future. There was an issue with the old water heater being taken up the steps with a dolly that scrapped all the way up the steps in pic 2. I called the main office, they apologized, and they sent Travis back out the next day to repaint. Ill still keep them in mind for future projects. thank you.

I had Stay Cool come out for my furnace that quit working while I had just had surgery. Cindy was able to get someone out right away, I had signed up for the membership club that saved me on my repairs, and felt very confident in the technician. He made me feel at ease and comfortable in my decision . Very friendly company that does the job right the first time!

Nathan and Trey came out to do an installation on the exterior, but stuck around to help test my system and give guidance on improving house heating. We found an issue with a fan not being connected to an exhaust pipe and they went out, got materials, and came back and fixed it that day!
