Fall is a season of crisp air, colorful leaves, and cozy moments. After months of sweltering summer heat, it’s nice to finally feel that cool breeze and thank that air conditioning system for all its hard work.
Halloween is right around the corner, and while the eerie decorations and spooky nights add some fun, the last thing you want is a spooky noise coming from your HVAC system as temperatures drop. There’s nothing fun about hearing strange clanks or experiencing cold air when your heat should be kicking in. Before those spooky sounds turn into real problems, let’s explore what might go wrong with your HVAC systems and what you can do to keep things running smoothly before fall hits.
Clogged Drain Lines
As temperatures cool down and your air conditioner takes a well-deserved break, you might notice that your drain lines are clogged. These lines help remove condensation from your HVAC unit, but over time, they can get backed up with dirt and debris. If left unchecked, this blockage can lead to leaks or water damage around your system. It’s especially noticeable when your cooling system switches over to your heating system, causing leftover condensation to accumulate. If you’re seeing water pooling around your HVAC system, it’s a clear sign your drain lines need attention.
Dirty Air Filters
One of the most common fall HVAC problems is dirty air filters. As you switch from central air units to heating, your system continues to push air through those same filters. If you haven’t replaced or cleaned them, they could be clogged with dirt, dust, and allergens. This reduces airflow, strains your system, and even impacts indoor air quality. A dirty air filter can make your heating system work harder than it should, lowering energy efficiency and driving up your energy costs.
Changing or cleaning your filters regularly is one of the simplest ways to maintain your HVAC system’s efficiency and prevent breakdowns during the colder months. It’s a critical HVAC maintenance tool you should never ignore.
Leaking Air Ducts
Leaky air ducts are another headache homeowners face when the weather turns chilly. Your HVAC system relies on properly sealed ducts to deliver hot air throughout your home. But over time, these ducts can develop small gaps or cracks, letting heated air escape into areas like attics or crawl spaces. This can cause uneven heating, drive up your energy costs, and reduce the overall efficiency of your heating equipment. You might not notice the leaks until the weather cools, but keeping an eye on energy bills and feeling for cold spots can help you detect a problem before it gets worse.
Broken/Malfunctioning Thermostats
Your thermostat is pretty much the only way for you to keep comfortable inside your home. However, when it malfunctions, you could be left shivering despite setting the temperature higher.
A broken thermostat may misread temperatures or fail to communicate with your HVAC system altogether. This could lead to your heating system not turning on when needed or, worse, running non-stop. If you find your HVAC unit running inconsistently, or if it’s producing cold air when it should be heating, your thermostat may be to blame.
Luckily, many thermostat issues are usually quick fixes, but getting it checked during maintenance service can save you from a bigger headache down the line.
Worn Refrigerant Pipes
Refrigerant pipes may sound more like a summer issue, but they’re vital to your HVAC system’s health year-round. These pipes transport refrigerant through your system, but as temperatures cool, any wear or damage can become more noticeable. If your refrigerant pipes are leaking or corroded, your HVAC system could struggle to maintain its cooling efficiency or even heat your home properly. Worn pipes can also lead to frozen evaporator coils or affect the overall performance of your system.
Blower Won’t Turn Off
If your blower fan runs continuously, it could signal a deeper issue within your system. A blower that won’t turn off is not only annoying but also a sign that your HVAC system is under strain. This problem might stem from faulty electrical components, issues with your thermostat, or even problems with the safety controls in your heating equipment.
Running non-stop can waste energy and shorten the lifespan of your HVAC system. Getting your system checked as soon as you notice this issue will help you avoid more costly repairs and ensure your home stays comfortable without unnecessary energy consumption.
