5 Signs Your Air Conditioner Has Sustained Storm Damage

July 19, 2026

Quick Answer: Signs of AC storm damage include a system that will not restart, weak cooling, refrigerant leaks, unusual noises, standing water around the outdoor unit, and burning odors. Turn the system off and schedule an inspection if you notice electrical damage, flooding, exposed wiring, or persistent performance problems. Air conditioners are designed to withstand routine exposure to rain, wind, heat, and other outdoor conditions. However, severe thunderstorms, hail, flooding, lightning, and wind-blown debris can damage the outdoor unit or its electrical components. Inspecting your cooling system after severe weather can help you identify damage before it causes energy waste, additional wear, or complete equipment failure. Here are five signs your air conditioner may have sustained storm damage. 1. Your Air Conditioner Will Not Turn Back On Severe storms frequently cause power outages and electrical surges. If your air conditioner was operating before the power went out, it may restart automatically once power is restored. However, a tripped breaker or damaged electrical component could prevent it from turning back on. First, confirm that the thermostat is set to cool and that the home has power. If the air conditioner and surrounding area are completely dry, you may check whether the...

R-22 vs R-410A: Is There a Difference?

July 13, 2026

Quick Answer: R-22 and R-410A are different refrigerants and are not compatible or interchangeable. R-22 has a 100-year global warming potential of 1,810, while R-410A has a GWP of 2,088. Existing systems can still be serviced with the refrigerant they were designed to use, but you cannot simply put R-410A into an R-22 system. Older air conditioning systems commonly used R-22, while many systems manufactured after 2010 used R-410A. Both substances are refrigerants that allow an air conditioner to absorb heat from inside a home and release it outdoors. However, R-22 and R-410A have different chemical compositions, operating pressures, lubricants, and equipment requirements. They cannot be mixed or substituted for one another without major system modifications. Understanding the differences between R-22 and R-410A can help O’Fallon homeowners make informed decisions about refrigerant leaks, AC repairs, and equipment replacement. Why Does an AC System Need Refrigerant? Refrigerant carries heat through an air conditioning system. It repeatedly changes between a liquid and a vapor as it circulates between the indoor and outdoor equipment. The compressor raises the pressure and temperature of the refrigerant vapor. The refrigerant then moves through the outdoor condenser coil, where it releases heat and condenses into a liquid....

Keep Your Summer Air Fresh and Cool With an Energy Recovery Ventilator

July 1, 2026

Modern, energy-efficient homes are tightly sealed, which is great for keeping cooling bills low during a hot summer. However, this airtight construction traps stale, polluted air inside. Without natural drafts, your indoor air can become stuffy, full of odors, and less healthy to breathe. Fresh outdoor air has difficulty entering, and contaminated indoor air has no way to escape. An energy recovery ventilator (ERV) is a ventilation solution designed specifically for this problem. It brings in fresh outdoor air while minimizing the loss of your conditioned, cool air. As homes become more airtight, ERVs can be a helpful part of maintaining ventilation, indoor comfort, and energy efficiency. This guide will explore how ERVs work, the problems they solve, and why they are an ideal addition to your home’s comfort system. Why Do Modern Homes Struggle With Stale Air? Newer construction techniques heavily focus on reducing air leakage. Upgrades like high-performance windows, advanced insulation, and tight building wraps are excellent for preventing conditioned air from escaping. The benefits of an airtight home include better energy efficiency, improved indoor environment by eliminating drafts, and lower utility costs. However, this efficiency comes at the cost of natural ventilation. In older, draftier homes, air...

Keeping Your St. Louis AC Running During Extreme Heat

June 8, 2026

A heat dome traps hot air over a region for days or even weeks at a time. When one settles over the St. Louis metro area, temperatures can exceed 100 degrees Fahrenheit. Meanwhile, the nighttime lows bring no relief. Your AC system runs almost nonstop under those conditions, and that demand pushes it closer to its limits every minute. Knowing how to manage your system during extreme heat can prevent a breakdown when you need cooling the most. Why a Heat Dome Pushes Your AC to Its Limits Most residential AC systems size for a design temperature around 95 degrees. Engineers use that benchmark because it covers the vast majority of summer days in the region. When outdoor temperatures stay above 100, your system loses the ability to keep up. The gap between indoor and outdoor temperatures grows wider than the system can bridge. High overnight temperatures during a heat dome add extra strain to your AC. Cooler nights give the unit a lighter workload and a chance to rest between cycles. When the lows stay above 80, the system runs more often through the night to hold your set temperature. That increased runtime adds wear to the compressor, fan...

Reasons 2026 May Be the Year Fixed-Speed ACs Become Obsolete

June 1, 2026

For many decades, fixed-speed AC units were the standard in homes all across areas like O’Fallon, MO. With this unit, you turn it on, and it runs at 100% capacity until the thermostat temperature is reached. In recent years, and especially now in 2026, variable-speed ACs are quickly taking their place. These units adjust their output in real time based on the temperature. It’s a much gentler process that also saves electricity. Fixed-speed air conditioners hung around so long because they were the only viable option for larger units like central ACs. With more market competition, government regulations, and technological advances, we’re seeing variable-speed ACs increase in popularity. The Precision of Variable-Speed Compressors The first huge advantage of a variable-speed compressor (VSC) model is that it’s all about precision. Fixed-speed compressors are an “all or nothing” style of machine. With a VSC model, your unit can kick on at 25% and gently lower the temperature. This saves a lot of electricity. Fixed-speed systems generally use more electricity because they operate at full capacity whenever they run. Gently running requires far less current. It also creates less wear and tear on the machine itself. The VSC model also excels at keeping...

Why Do Air Conditioners Freeze Up?

May 17, 2026

Quick Answer: Air conditioners usually freeze because airflow across the evaporator coil is restricted or refrigerant pressure is too low. Common causes include a dirty filter, blocked vents, a dirty coil, blower problems, refrigerant leaks, low outdoor temperatures, or a faulty TXV. Turn the cooling off and allow the system to thaw before restarting it. Finding ice on your air conditioner during an O’Fallon heatwave may seem strange, but it is a common sign that the cooling system is not operating properly. The ice usually begins on the indoor evaporator coil, although it can spread along the refrigerant line and become visible near the outside AC unit. A frozen air conditioner may produce weak airflow, blow warm air, run continuously, or stop cooling altogether. Continuing to operate the system while it is frozen can strain the compressor and allow a relatively minor problem to cause more extensive damage. Contact Us for AC Service How Can You Tell If Your AC Is Frozen? The evaporator coil is normally located inside the air handler or above the furnace, so the ice may not be immediately visible. Common warning signs include: Warm air coming from the vents Weak or reduced airflow The air...

Cooling vs Moisture Control: Why Dehumidifiers Matter in Missouri

May 2, 2026

Missouri summers bring more than heat. They bring high humidity that can make you feel sticky and uncomfortable. You rely on your air conditioner to keep the temperature bearable. An AC system does remove some humidity, but it can’t always control moisture levels effectively on its own. Understanding the difference between cooling and dehumidification can help you create a more comfortable home and avoid overworking your HVAC system during summer. Cooling and Moisture Control Are Not the Same Thing It’s easy to assume that lowering the temperature will solve comfort issues, but humidity is equally important. When moisture levels rise, your body can’t cool itself efficiently because sweat evaporates more slowly. This makes the air feel warmer than it is, even if your thermostat shows a comfortable setting. Your air conditioner focuses on reducing the temperature. It removes some moisture as a byproduct of cooling, but that process depends on how long the system runs. In many circumstances, it may not run long enough to remove humidity. This creates a situation where your home feels cool but still damp. A dedicated dehumidifier can target the moisture more effectively. What Your AC Can and Can’t Do Your air conditioner’s primary function...
