Don’t Panic When Your Furnace Won’t Shut Down

October 21, 2026

Updated October 21, 2026 If your furnace or heating system won’t shut down, you shouldn’t worry. You just need to set up a service call with your local heating company. In the meantime, there are ways to shut down the unit to avoid any further damage to your system. Why Won’t My System Turn Off? When your system is constantly running, this is a sign that something is wrong. There are several causes for this issue. One of the most common issues is the thermostat. The wiring, switches, or heating sensors can fail on your unit. If this is the case, then you’ll need to replace the thermostat with a newer model. A damaged primary controller can also cause the furnace to stay turned on. This is the main heating element of the system. If it stops functioning, then the furnace can’t regulate temperature. Your system may have another mechanical issue as well. A boiler system uses a check valve to warm your home through heated water sent through radiators. A properly functioning valve will circulate the water throughout the system. A faulty check valve could be the cause of this type of heating system to fail. If your heating...

Furnace Maintenance and Your Warranty: What O’Fallon Homeowners Need to Know

October 19, 2026

As a homeowner, your furnace warranty provides peace of mind and acts as valuable protection against unexpected repair costs. A common question we hear is wondering whether routine furnace maintenance is necessary to keep that warranty valid. The short answer is yes. In many cases, professional maintenance is a key requirement for your warranty. The exact requirements depend on the manufacturer, the specific equipment, your original installation records, and your service history. Most furnace warranties depend on proper installation by a qualified professional and documented, routine maintenance. Neglecting annual service can give manufacturers grounds to deny a claim, leaving you to pay for a part that should have been covered. How Furnace Warranties Usually Work A new furnace typically comes with a manufacturer’s limited parts warranty. This warranty covers the cost of replacement for specific components that fail due to a manufacturing defect within a set period. The standard term is often five years, but many manufacturers extend it to 10 years or even a lifetime for major components if you register the product within a specific timeframe after installation. It’s important to distinguish between a parts warranty and a labor warranty. The manufacturer’s warranty almost always covers only the...

What’s the Difference Between a Furnace Tune-Up and a Furnace Inspection?

October 14, 2026

As a homeowner in O’Fallon, MO, keeping your furnace in top condition is essential for staying comfortable during our cold winters. When you look into professional heating services, you’ll often see “furnace inspection” and “furnace tune-up” used interchangeably. What sets them apart? A furnace inspection primarily checks the system’s condition and verifies its safety. A furnace tune-up, on the other hand, is a more comprehensive service that includes an inspection plus critical cleaning, testing, and adjustments designed to improve performance and efficiency. What a Furnace Inspection Covers Think of a furnace inspection as a diagnostic checkup. The main goal is to identify any existing problems or potential safety hazards. Homeowners often use this service when buying or selling a property, or when they have a specific concern about their heating system’s operation. A technician will visually assess the furnace and its components. During a standard furnace inspection, a technician checks key areas to ensure they function correctly. The inspection includes checking the heat exchanger for cracks, which could lead to carbon monoxide leaks. The technician also checks the burner ignition, flame sensor, and electrical wiring for signs of wear or damage, and inspects the venting system for blockages or corrosion....

Furnace Repair or Replacement? How to Know Before Heating Season Starts

September 14, 2026

Deciding whether an aging furnace needs another repair or a full replacement brings uncertainty. Homeowners in O’Fallon, MO, often face this choice as cold weather approaches. You want a warm home without taking on unnecessary costs. Deciding now provides peace of mind before winter begins. The best choice depends on your furnace’s condition, repair history, comfort, efficiency, and safety. A single isolated problem usually calls for a targeted repair. However, replacement makes more sense when failures recur or performance declines. Evaluating these factors helps you choose the most reliable path forward. When Is Furnace Repair the Better Choice? A repair is often the best choice when a problem is limited. If your heating system is generally reliable, one fix can restore performance. You do not need to replace a furnace just because it needs minor service. A repair makes sense when key replacement parts are readily available. It is also ideal if your furnace still heats your home evenly. Issues like a worn belt or a faulty ignitor are reasonable to fix. Standard maintenance and quick repairs keep dependable systems running smoothly for years. What Signs Suggest Replacement May Be Better? Certain warning signs indicate that replacing your furnace might...

Why Your Attic Temperature Matters: The Link Between Insulation, Ventilation, and AC Lifespan

August 8, 2026

When you think about keeping your home cool and comfortable, your air conditioner is probably the first thing that comes to mind. However, your HVAC system doesn’t work in isolation. It’s part of a complex network that includes your home’s entire structure, and one of the most overlooked yet critical components of this network is your attic. The condition of your attic has a direct and significant impact on how well your air conditioner performs. If your attic traps excessive heat or moisture, your AC has to work much harder to maintain a comfortable temperature.

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....
