Furnace Failure: A Guide To Spotting 5 Common Seasonal HVAC Problems

Furnace Failure: A Guide To Spotting 5 Common Seasonal HVAC Problems

As the temperatures drop and the leaves start to fall, it's a clear sign that winter is just around the corner.

It's also a signal for homeowners to prepare their furnaces for the chilly months ahead. To keep your home cozy and comfortable, it's crucial to be aware of common furnace issues that can arise during the fall and winter seasons. So, we’ve prepared this helpful guide that will maximize your comfort in the coming months by keeping you aware of the Top Five Furnace Issues To Be On The Look Out For.

1. Irregular Heating

Have you noticed uneven heating in your home? Are some rooms nice and toasty while others are already settling into a Central Valley January? This issue is likely the result of a malfunctioning thermostat or clogged air ducts. And to tackle the problem, you should always start by checking your thermostat settings, buttons, and batteries.

If the issue persists, it's time to consult a professional tech who can diagnose and repair it more swiftly.

2. Reduced Airflow

A decrease in airflow can also lead to inadequate heating and cause your furnace to work harder, consuming more energy. That’s usually a result of dirty air filters – and regularly changing or cleaning the filters can prevent this issue and improve the efficiency of your furnace.

If the problem persists, consider having your ductwork inspected for cracks and blockages.

3. Strange Noises

If your furnace starts making unusual noises, it should be a clear indication that something's not right. Common sounds include banging, clanging, or screeching. These noises could be the result of any number of system disruptions, including loose or damaged components, worn-out belts, or a malfunctioning blower motor.

Ignoring these sounds can lead to costly repairs in the future, so it's best to address them promptly.

4. Frequent Cycling

Furnace cycling refers to the process of turning on and off. If your furnace is cycling more frequently than usual, it is likely due to things like a dirty or faulty flame sensor, a clogged air filter, or improper thermostat settings.

This is another major problem, as frequent cycling can not only increase your energy bills but also decrease the lifespan of your furnace, resulting in a costly, inconvenient replacement.

5. Pilot Light Problems

For older furnaces, the pilot light is a critical component that needs your attention. If the pilot light is frequently going out or producing a weak flame, it may be due to a dirty or malfunctioning thermocouple.

Addressing this issue is essential to ensure your furnace's safe and efficient operation.

Let Someone Else Worry About All That!
