Does your furnace run the way it used to? Sometimes it can be difficult to put your finger on what changed (or when it changed).
These changes can be subtle at first. You may notice a change in airflow from some of your registers. Maybe your furnace is running longer or not as long as normally does. You may even notice new sounds, smells and pools of water coming from your furnace.
These changes can indicate that your furnace needs service or repairs.
I’ve worked in HVAC service for a little over 15 years. And while I could list the performance benchmarks that I look for as an HVAC professional, that list likely wouldn’t help many homeowners.
Your furnace is a critical component of your home’s heating system, and it’s essential to keep it in good working condition to ensure comfort and safety. Here are the top signs that indicate your furnace may require repair or replacement:
(a) Inconsistent Heating: If some rooms in your home are significantly colder than others or if you notice inconsistent heating throughout your house, it may be a sign that your furnace is struggling to distribute heat evenly.
(b) Increased Energy Bills: A sudden and unexplained spike in your energy bills, especially during the heating season, could be a sign that your furnace is operating inefficiently.
(c) Frequent Repairs: If you find yourself repeatedly calling for furnace repairs, it may be more cost-effective in the long run to consider replacing the furnace.
(d) Unusual Noises: Strange or loud noises coming from your furnace, such as banging, rattling, or squealing, can indicate mechanical problems. These noises could be caused by loose or damaged components.
(e) Yellow or Flickering Pilot Light: If you have a gas furnace, a yellow or flickering pilot light may indicate a combustion problem. This could be due to a dirty burner, a gas supply issue, or improper ventilation.
When you observe any of these signs, it’s advisable to contact a licensed HVAC technician to inspect your furnace and recommend the appropriate course of action, whether that’s repair or replacement. Regular maintenance and timely repairs can extend the life of your furnace and ensure it operates efficiently and safely.
