Four Small Warning Signs Your Furnace May Need Repairs

It's easy to notice when your furnace won't heat, but it's usually cheaper to repair it much sooner than that. Here are four signs of a growing problem in your furnace unit that should be repaired. 

Weak Airflow

When you turn on your furnace, you expect to feel a steady flow of warm air circulating throughout your home. However, if you notice weak airflow coming from your vents, it could be a sign that your furnace is in need of repairs. Several factors can contribute to this issue.

You may just need to replace your air filter, but a malfunctioning blower motor or a blocked duct system can also result in weak airflow. If you consistently experience weak airflow, it is contact an HVAC contractor to inspect and resolve the issue promptly.

Increased Dust or Allergens

If you've noticed an increase in dust or allergens in your home, your furnace may be to blame. A properly functioning furnace should help filter and circulate clean air throughout your living space. However, when your furnace is in need of repairs, it may fail to effectively filter out dust particles and allergens, leading to poor indoor air quality. Dirty air filters, duct leaks, or a malfunctioning air purification system can contribute to this problem. 

Short Cycling

Short cycling refers to a situation where your furnace turns on and off frequently, often before reaching the desired temperature in your home. This can be an indication of an underlying problem that requires professional attention. Several problems can cause short cycling, including a malfunctioning thermostat, a clogged air filter, or an issue with the heat exchanger. Ignoring this warning sign can lead to increased energy consumption, inefficient heating, and potential damage to your furnace so you should schedule a furnace unit repair ASAP.

Yellow or Flickering Pilot Light

The pilot light in your furnace should burn a steady blue flame. If you observe a yellow or flickering flame, it may indicate a problem with your furnace that requires immediate attention.

A yellow or flickering pilot light could be a sign of a gas leak, which is a serious safety hazard. Gas leaks can be caused by a faulty burner or a damaged gas valve. Even if you don't have a gas leak, you still likely have a problem with your burner or with air leaks near the pilot light. These are all serious issues that require immediate furnace unit repair.
