You rely on your heating system to keep you comfortable throughout the coolest months of the year. However, with age, your system might develop wear and tear that renders it less effective. To avoid a scenario where it shuts down unexpectedly, look out for the following signs that you need heating repairs. 

When to Contact an HVAC Technician

1. Inconsistent Heating

When the heater seems to warm some rooms but barely affects others, it could indicate a clogged air filter, which homeowners can replace themselves. If this is not the issue, you might have dirty ducts. Inspect the vents around your home to see if you can spot dust and arrange for professional cleaning if so.

The problem could also be a worn-out belt that is preventing the furnace’s blower fan from working properly, which will require heating repair.

2. Strange Noises

Central heating systems only produce a low hum when they work properly. If you hear anything else, contact an HVAC contractor promptly. A scraping noise, for example, could indicate that the motor inside the furnace is loose. That could cause damage to the blower fan, leading to an eventual breakdown. Rumbling sounds may be due to a low pilot flame or even carbon monoxide presence, both of which can be dangerous.

3. Light Changes

The pilot light typically burns bright blue. If it appears more yellow or orange in color, that’s a sign that the furnace isn’t burning efficiently. The problem is likely due to low oxygen levels, resulting in reduced heat. It could also be indicative of carbon monoxide. 

Sometimes dirt and debris build up on the intake valve, which, in turn, limits oxygen exposure and dulls the flame. Usually, a component called the thermocouple can detect problems with the pilot light in time and turn off the gas supply as a safety measure. However, if this part is damaged, it won’t work efficiently. Your technician will assess all components to ensure that the furnace is safe to use.
