Why Can’t My Furnace Make the House Warm Enough?

cold-man-and-woman-in-parkas

Your furnace is supposed to be a reliable source for heat through the winters, but what happens when it starts falling behind? A furnace that struggles to maintain the desired temperature can turn winter into an uncomfortable one. 

We’ve seen this issue in many homes, and the causes can range from troubles that will require furnace repair in Eugene, OR to more serious ones that mean it’s time for a new furnace. Let’s explore why your furnace might not be keeping your home warm enough and what to do about it.

ONE: A Clogged or Dirty Air Filter

One of the most common culprits for a poorly performing furnace is a dirty air filter. Over time, filters accumulate dust, dirt, and debris, restricting airflow and making it harder for the furnace to distribute warm air throughout your home. A clogged filter not only reduces heating efficiency but also puts extra strain on the system, potentially leading to breakdowns.

  • Solution: Check and replace your furnace filter regularly, usually every 1–3 months, depending on usage and filter type.

TWO: Thermostat Issues

Your furnace might be working fine, but if the thermostat isn’t functioning correctly, it could miscommunicate with the system. Incorrect settings, dead batteries, or a faulty thermostat can all lead to uneven or insufficient heating.

  • Solution: Start by ensuring the thermostat is set to “heat” and is at the desired temperature. If problems persist, consider replacing the batteries or calling a professional to inspect the thermostat.

THREE: Blocked Air Vents

Furniture, curtains, or other objects might be obstructing your home’s air vents, preventing the warm air from circulating effectively. This can create cold spots and uneven heating.

  • Solution: Check all air vents to ensure they’re open and free of obstructions. Rearrange furniture if necessary to allow proper airflow.

FOUR: An Undersized Furnace

If your furnace is too small for your home, it may not be able to generate enough heat to keep the entire house warm, especially during extreme cold spells. This is a common issue in homes where the furnace was improperly sized during installation.

  • Solution: Consult an HVAC expert to evaluate your home’s heating requirements. If the furnace is undersized, replacing it with a properly sized unit may be necessary.

FIVE: Furnace Is Too Old

Furnaces aren’t designed to last forever. The average lifespan of a well-maintained furnace is about 15–20 years. As furnaces age, they lose efficiency and struggle to perform as well as they once did. If your furnace is nearing the end of its lifespan, it may simply be unable to meet your heating demands anymore.

  • Solution: If your furnace is over 15 years old and frequently requires repairs, it’s time to consider replacing it with a new, energy-efficient model. Modern furnaces offer improved heating performance and lower operating costs.
