If your heat goes off, it’s easy to identify the culprit. But before that happens, your furnace may be giving you some hints that something’s not quite right.
Furnace Keeps Turning On and Off
If you notice short-cycling (your furnace turning on and then quickly turning off), something inside the furnace is malfunctioning and it’s time to call a professional.
Heating Bills Increase Suddenly
This is an indication that your system is losing efficiency. A thorough system cleaning and filter change may solve the problem. Or if your system is more than 15 years old, it may be time to replace it with a newer, higher efficiency unit.
Furnace is Making Strange Noises
Do you hear strange banging, rattling or squealing noises? Things like broken fan belts, malfunctioning blower motors, or broken or loose internal components can be to blame.
Cold Spots Around Your House
If you notice cold spots throughout your home, weak airflow coming out of your vents, or your system just doesn’t seem to be heating your home the way it should, it’s probably time for furnace service.
Burner Flame Yellow Instead of Blue
A healthy pilot light should be blue. If it appears to be a different color, especially yellow, this is an indication that you have a ventilation problem. This is caused when gases such as carbon monoxide build up in the system and should be addressed immediately.
Poor Air Quality in Your Home
Have you noticed a reduction in the air quality of your home? You may notice more dust in the air or your family may have increased issues with colds or allergies. Your heating system has a direct impact on your home’s air quality. These signs could all be indications that your system needs to be professionally cleaned.
