Stay Cool Climate Control

Thorough Energy Auditing

High utility bills, uneven temperatures, and drafty rooms are clear signs that energy is being wasted in your home. These issues can cause HVAC equipment to work harder than necessary, increase monthly costs, and leave you feeling uncomfortable in certain areas of the house. Over time, small inefficiencies turn into ongoing expenses that add up quickly.

Stay Cool Climate Control provides professional energy auditing in O’Fallon, MO and the Greater St. Charles County area to uncover the source of those problems. Our team uses advanced tools to evaluate your HVAC system, insulation, ductwork, windows, doors, and appliances with a detailed eye for inefficiency. We then create a step-by-step plan designed to lower energy bills, improve comfort, and enhance your home’s efficiency all year long. Call us today to schedule your energy audit and start making your home more efficient.

What Is Energy Auditing and Why Do I Need It?

Energy auditing is a detailed evaluation of your home that identifies areas where energy is being lost or wasted. The purpose is to measure how efficiently your home uses energy and to uncover opportunities for improvement that can lower utility bills and create a more comfortable living space. During an audit, trained technicians use specialized tools to test, measure, and inspect different parts of the home to provide a complete picture of its performance.

You need an energy audit because small inefficiencies can add up to big costs over time. Drafty windows, leaky ductwork, poor insulation, or an aging HVAC system all contribute to wasted energy and higher bills. A professional audit shows you exactly where improvements will make the greatest impact, giving you a clear plan to save money and keep your home comfortable in every season.

Energy Auditing Services We Provide

Stay Cool Climate Control offers comprehensive energy auditing services that help homeowners save money and improve indoor comfort. Our detailed home energy audits combine advanced diagnostic tools with HVAC expertise to uncover inefficiencies and provide clear solutions for long-term savings.

HVAC System Evaluation

Our technicians carefully examine your heating and cooling equipment to determine how efficiently it is running. This part of the energy audit often reveals issues such as clogged filters, outdated systems, or poor airflow that contribute to higher energy bills. By identifying these problems early, we can recommend the most effective repairs or upgrades to improve performance and efficiency.

Insulation and Air Leak Detection

Proper insulation and a well-sealed home are critical to maintaining consistent indoor temperatures. During the energy audit, we check attics, crawlspaces, doors, and windows to locate leaks that let conditioned air escape. Addressing these gaps can significantly lower energy costs while making your home more comfortable year-round.

Ductwork Inspection

Leaky ducts are one of the biggest sources of wasted energy in a home. As part of your energy auditing service, we test ductwork for leaks, blockages, and poor connections that reduce airflow and strain your HVAC system. Fixing these problems helps ensure heated or cooled air reaches every room effectively.

Appliance and Lighting Review

Older appliances and outdated lighting often use far more energy than newer, efficient models. During an audit, we review your major appliances and lighting systems to highlight opportunities for improvement. Even simple changes like switching to LED lighting can have a noticeable impact on your monthly bills.

Utility Bill Analysis

Your past utility bills contain valuable data about how your household uses energy. We analyze these records during your energy audit to identify seasonal patterns, spikes in usage, or areas of unnecessary waste. This allows us to recommend specific changes that will deliver measurable savings.

Customized Energy Report

At the end of every energy audit, we provide a personalized report tailored to your home. This document outlines the issues we discovered, the improvements we recommend, and the potential savings you can expect. With this clear plan in hand, you can prioritize upgrades that will make the biggest difference.

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.
