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.

Hear from Our Satisfied Customers

Cole is very knowledgeable alot of information came my way. Almost a tad to much, but I am glad it came. As opposed to not enough information, in regards to what. He was seeing in our system, compared to other homes. He explained all my options on how to maintain our system. Or a complete new system with the issue with ours. No scare tactics,or trying to sell the biggest system. We ended up buying right in the middle range of systems, glad Cole explained all of our options. Update we purchased new HVAC system, along with a humidifier. Brandon and Carter were top notch, texted to let us know they were on their way. Originally told us about 8 hours to install, got it done in just over 6 I think. They didn't rush the install to get down quicker, they just are experienced. Professional from start to finish, Brandon explained every step he did. From the the new equipment how it flows,to new materials used to get it all completed. Carter was great showing me the thermostat and the Ac unit rundown outside. Great job boy's keep on doing.

I highly recommend Stay Cool Climate Control. They are a local and family-owned company. Cole came out and did a service check, he went over and explained what was wrong with my unit and went over some options. Eric came out and went over all my options. They both were very informative. Brandon did a great job installing my new system. He explained everything after the install was done. Being such a large purchase/investment, you want to go with someone you can trust. These guys are great!!

I highly recommend Stay Cool Climate Control. Everyone from the office to the technician is extremely professional, courteous and a pleasure to work with. Our technician today was Cole. He notified us when he was on his way. While here, he patiently walked us through the current state of our HVAC and recommended having the blower motor cleaned. There was no high pressure sales pitch, just facts.

Jacob was very professional and courteous. Let us know the return air to the blower was undersized. Recommended we replace the blower in the future if necessary rather than replace expensive ductwork now.
