Is your furnace acting up? Whether you’re dealing with an older model or a brand-new system, furnaces can develop quirks that leave you scratching your head.
At Air Repair Pros in Frisco, we’ve seen it all when it comes to heating systems. Let’s break down some common issues you might face, depending on your furnace’s age.
Understanding furnace efficiency
Before diving into specific problems, it’s crucial to understand AFUE – Annual Fuel Utilization Efficiency. This percentage tells you how much of your fuel actually turns into heat for your home. Older furnaces typically hover around 80% AFUE, while newer models can reach up to 98%. Higher efficiency is great for your wallet, but it can also mean more complex components.
Common problems in older furnaces
Older furnaces often face issues related to wear and tear on basic components. One of the most serious problems is a cracked or rusted heat exchanger. This isn’t just inefficient; it can be dangerous, potentially allowing carbon monoxide to leak into your home. Regular inspections are crucial to catch this problem early.
Another common issue is blower motor burnout. The blower motor is responsible for pushing heated air through your ducts. In older models, these motors can wear out over time, leading to poor airflow or complete failure. Signs of a failing blower motor include unusual noises, inconsistent airflow, or a furnace that runs constantly without reaching the desired temperature.
Challenges with modern, high-efficiency furnaces
Modern, high-efficiency furnaces have their own set of potential issues, often related to their more complex components. Pressure switch problems are common. These safety devices ensure that combustion gases are venting properly. If a pressure switch fails or becomes blocked, it can cause your furnace to shut down as a safety precaution.
Ignition systems in newer furnaces can also be a source of trouble. Unlike older models with standing pilot lights, new furnaces use electronic ignition systems. When these fail, your furnace won’t be able to light the burners and produce heat.
Another issue unique to high-efficiency furnaces is related to condensate handling. If the condensate drain lines clog or the condensate pump fails, it can cause your furnace to stop working to prevent water damage.
When to call for professional help
While understanding these common issues can help you communicate effectively with an Air Repair Pros technician, it’s important to remember that furnace repair is not a DIY job. Heating systems involve gas, electricity, and potentially dangerous components. Attempting repairs yourself can void warranties, cause further damage, or even create safety hazards.
