You may be committing to yearly furnace inspections that have kept your furnace functioning properly thus far, but what if something happens between check-ins? Even with efficient heating cycles that leave your home pleasantly warm, there’s no guarantee your furnace is up to par.
Below are some tell-tale signs that’ll help you detect imperfections in your furnace that can damage your entire HVAC system.
Unusual Noises
You may also hear a slight humming coming from the furnace burner. This humming may be like an air conditioner or HVAC unit in tone. Since it’s the blower’s responsibility to transmit hot air into the ducts that will travel into your living quarters, a soft buzzing from the motor is expected.
However, don’t overlook it if your blower motor draws more attention with louder or harsh new sounds. These sounds can mean that your blower motor is run down and needs replacing:
- Grinding
- Clanking
- Rattling
- Squealing
Squealing can also signify bearing issues or an old, loose fan belt. Other ways to tell it’s time for a furnace repair include:
– A constant clicking sound, meaning either the flame sensor or the pilot light is malfunctioning.
– A clicking sound that continues once the cycle begins, indicating a bad control panel or faulty circuit board.
– An explosive sound, which can indicate various issues from mild to severe.
Inadequate Heating Power
Short Cycling


What do you call a person who fixes furnaces?
An HVAC technician, also known as a heating, ventilation, and air conditioning expert, is a qualified worker who replaces and repairs furnaces.
Why is my furnace running but with no heat?
Several things can cause your furnace to produce no heat when running. Dust, dirt, and grime from the air can block the airflow in the filters. These blockages can lead to the chambers or heat exchanger overheating and short cycling.
While cleaning the filters on your system can be a quick fix, feel free to contact a specialist like those at Topline Heating & Air to walk you through the steps. We’ll also come over to examine other possible issues, such as a problematic thermostat, exchanger, or pilot light on a gas furnace.
Why is my furnace not turning on?
If your furnace isn’t turning on altogether, the cause could be the flame sensor or ignitor. You can usually tell if those are the problem if you hear an unwavering clicking sound as a cycle begins.
You may also have a broken or clogged component restricting the warm air, including a worn blower motor, pilot light, or thermostat.
