Signs You Need Furnace Repair
When your furnace is damaged, neglecting the problem will worsen it, causing you to spend money on expensive repairs later. Not only that, but a poorly functioning furnace will affect your comfort during the winter months. We recommend paying attention to the following signs that can suggest a need for furnace repair in St. Catharines:
-
Increased energy costs
If your energy bills have risen this winter for no apparent reason, your poorly functioning furnace might be to blame. -
Uneven heating
Under normal circumstances, your furnace should be heating your property evenly, leaving no hot and cold spots. The failure to do so means that your unit might require repairs. -
Unusual sounds
A constant whirring sound is typical in a furnace, but unusual banging, rattling, groaning and humming mean trouble. If the noises continue, you should schedule repairs. -
Abnormal smells
Abnormal smells can indicate poor combustion, aldehydes, or a gas leak. Whatever the reason, unusual smells from your furnace are a cause for alarm and urgent action. -
Carbon monoxide alarm
You shouldn't ignore a carbon monoxide alarm under any circumstances. Please evacuate your property as soon as your alarm goes off and call for urgent repair services.
