🥶 Don’t wait until your furnace leaves you in the cold!
Here are 11 warning signs that could mean your heating system needs service.
🔥 Furnace/heat not turning on — If your system struggles to start or shuts off unexpectedly, have it checked before it gets worse.
🌡️ Uneven heating — Cold rooms or areas of the house can indicate airflow or system issues.
💨 Weak airflow — Check your filter first, but weak airflow can also point to a larger problem.
🔊 Strange noises — Banging, squealing, rattling, grinding, or unusual humming shouldn’t be ignored.
👃 Burning or unusual smells — A brief dusty smell when first turning on the heat can happen, but persistent or strong odors should be investigated.
💧 Water around the furnace — Leaks or unexpected moisture can signal a problem that needs attention.
⚡ Frequent cycling — If your heat keeps turning on and off more often than normal, something may be wrong.
📈 Higher-than-normal energy bills — A sudden increase can be a sign your system isn’t operating efficiently.
🧊 Frozen or blocked outdoor equipment — Keep snow, ice, leaves, and debris away from outdoor HVAC equipment and its airflow.
🧹 Dirty air filters — A clogged filter can restrict airflow and make your system work harder.
🚨 Carbon monoxide concerns — If you have fuel-burning equipment, make sure your carbon monoxide detectors are working and never ignore a CO alarm.
