6 Common Reasons Your Furnace May Need Repair

Every member of the Signature HVAC team has years of experience handling every furnace concern. Look for these most common furnace issues, and if you notice them, call Signature HVAC:

  1. Clogs or debris in the AC ducts: Duct systems collect a considerable amount of dust, pollen, and other allergens over time, which can contribute to poor airflow and air quality issues.
  2. Electrical issues, including frequent breaker trips: Routine furnace maintenance is critical to keep your unit operating properly and without interruption.
  3. Dirty, grimy components in your furnace: Similar to your ducts, components tend to wear down and collect gunk over time. This can lead to huge efficiency drops and even potentially trigger a furnace breakdown.
  4. Blowing cool or cold air, or having weak airflow: This usually relates to your furnace overheating or an unruly pilot light. If overheating is the cause, call for repair immediately.
  5. The thermostat displays incorrect values: Is your thermostat reading 70 degrees when it feels more like 50? This often relates to electrical connection issues. No matter the cause, Signature HVAC can help.
  6. The furnace is unresponsive: A complete breakdown can result from a wide range of issues, but our experts have seen and repaired them all.

When you notice your furnace isn’t working like it used to, you need to call Signature HVAC in West Chester. With our heating repairs, you can avoid a complete breakdown.

Frequently Asked Questions

Can a cracked heat exchanger be repaired?

Unfortunately, this is one of the few problems that require replacement. A cracked heat exchanger can’t be welded or glued back together because there remains the potential for a fatal carbon monoxide leak.

Replacing a heat exchanger is a time-intensive process, and many replacements take up to a full day to complete.

How often should I change the air filter?

Generally, about every three months. However, if you have pets, significant dust, etc., you may want to change it every 30–60 days. Staying on top of filter changes will improve system efficiency, improve indoor air quality, and help prolong your furnace’s serviceable life span.

When should I replace my old furnace?

Most furnaces will last between 15 and 20 years, but some well-built and exceptionally well-maintained models can operate for as long as 30 years. As your furnace ages, it will lose efficiency and require increasingly frequent repairs.

If you have an older furnace that isn’t performing efficiently or one that needs repairs that exceed 50% of the replacement cost, investing in a new furnace can be a cost-effective investment in your comfort.

Can I perform furnace maintenance myself?

Absolutely. There are many simple tasks you can perform every month, such as inspecting and cleaning debris and blockages from your registers, changing the cabinet’s air filters, and inspecting for signs of leaks or corrosion.

However, we recommend leaving any tightening, adjusting, or lubricating to a professional, as these tasks can damage your furnace if performed incorrectly.

What are the most common causes of furnace failure?

Many things can cause your furnace to fail. However, these are the most common reasons we encounter:

  • Dirty air filters
  • Blocked ducts/vents
  • Malfunctioning blower motors
  • Clogged fuel supply
  • Poor drainage
  • Lack of maintenance
