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....

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.

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?
