A chilly morning, a mug of hot chocolate or coffee in hand, and the comforting hum of your furnace in the background, this is the ideal winter for many homeowners. However, like any other appliance, furnaces have their moments of wear and tear. Before a minor issue turns into a serious breakdown, often there are warning signs. Ambient Heating & Air Conditioning would like to share some of the common signs a furnace will share with owners that the unit is in need of a tune-up.

Signs Your Furnace Needs a Tune Up

Unusual Noises: While no furnace runs with complete silence, sudden, unusual noises like banging, rattling, or humming can be signs of underlying problems. These sounds can stem from loose parts, an unbalanced blower, or other internal issues.
Frequent Short Cycling: If your furnace turns on and off frequently, it is not just annoying, it is a sign that something might be going wrong. This frequent cycling could be due to an oversized furnace, faulty thermostat, or an airflow problem.
Spike in Energy Bills: If you notice your energy bills creeping up without any change in your usage habits, it may be because your furnace is working harder than it should, pointing to a possible efficiency issue.
Uneven Heating Across Rooms: Does one room feel like a sauna while another feels like an icebox? Uneven heating is a clear sign that your furnace might not be distributing air properly, which can arise from ductwork issues or a failing blower.
Yellow Pilot Light: For furnaces with a pilot light, this light should always burn blue. If it is yellow or any other color, it might be a sign of a poor combustion, which can lead to the production of carbon monoxide which is a dangerous and odorless gas.
Difficulty Starting Furnace: If your furnace struggles to start or does not stay on once started, it is a clear sign that a tune-up or repair is in order. This could be due to a range of issues, from faulty wiring to a malfunctioning thermostat.
Presence of Soot Around Registers: A well-functioning furnace should not produce any soot. If you notice black soot or dust around the furnace registers, it could be a sign of inefficient burning, which warrants immediate attention.
Age of Furnace: If your furnace is over ten years old and has not been serviced in a while, it is wise to consider a tune-up. While the equipment may be working fine now, regular check-ups can extend its lifespan and ensure efficient operation.
Reduced Air Quality: An increase in dust, allergens, or dry air in your home can be tied back to furnace issues. A tune-up can help address these air quality concerns by ensuring all components are clean and functioning optimally.
