Why is My Greenwood Furnace Struggling to Keep up With Cold Weather?

Jan 17, 2024

As the chilly winds of winter sweep across Greenwood and central Indiana, your furnace becomes your home’s hero, safely keeping you and your family warm and comfortable. Sometimes, though, it feels like your furnace is just struggling to keep up with the chill, and you’re no longer as comfortable as you want to be. What’s the reason for that? Typically, it’s one or more of these factors:

Wrong Size

Furnaces are manufactured in different sizes to serve the wide range of home sizes. If your furnace is too large or too small for your home, you probably won’t get the performance you want. An oversized furnace may cycle on and off frequently, resulting in inefficiency and faster wear, while an undersized model probably won’t be able to reach the temperature you set on the coldest days.

Growing Old

Home appliances don’t last forever, and your furnace is no expectation. Today’s top-quality models can deliver up to 20 years of service, but if your home’s furnace is more than decade old, it probably isn’t generating and distributing heat as effectively as it used to do. Regular maintenance is crucial to address wear and tear, but if your furnace is reaching the end of its expected lifespan, replacing it today may lower your energy bills and improve your comfort for years to come.

Dirty Filters

Sometimes, improving your furnace’s operations is as quick and easy as changing its filter. Furnace filters trap and prevent dust, debris, and allergens from entering your Greenwood-area home’s ductwork system. Over time, these filters become saturated and obstructed, reducing the heat that’s distributed throughout your home, causing your furnace to work harder. Regularly replacing your filters keeps your furnace operating efficiently.

Thin Insulation

Inadequate insulation in your home’s walls allows heat to escape, forcing your furnace to work harder to compensate. Check for drafts, seal gaps around windows and doors, and consider adding insulation to your walls and attic to not only ease the burden on your furnace but also enhance the heating systems’ overall energy efficiency.

Thermostat Trouble

Sometimes, what a Greenwood homeowner thinks is a furnace problem turns out to be a faulty thermostat. Your home’s thermostat serves as the command center for your heating system, and if there are programming errors, dead batteries, or faulty wiring, your furnace may struggle to maintain the desired temperature. Upgrading to a programmable thermostat can also match your heating system’s operation to your lifestyle, keeping it at peak efficiency while you feel more comfortable.

Ignition Issues

If your furnace is struggling to ignite or if the pilot light keeps going out, it can’t generate enough heat to keep your home warms. Ignition issues may be caused by a faulty thermocouple, a dirty or damaged pilot assembly, or a malfunctioning electronic ignition system. Regular maintenance and prompt repairs can help address these issues and prevent further complications.

Doomed Ductwork

The ductwork in your home plays a crucial role in distributing heated air. Leaks, blockages, or poorly designed duct systems can impede the flow of warm air, making it difficult for your furnace to keep up with the weather. Have a Johnson Heating Cooling & Plumbing professional inspect your ductwork for any issues and make necessary repairs or improvements.
