Signs You Need Furnace Maintenance

Below are some of the most common signs that you need furnace maintenance in Silver Spring, MD. 

Increased Energy Bills

The longer you go without maintenance, the harder your furnace system has to work to get the same results. The outcome is your energy bills rise while furnace performance stays the same. Regular maintenance keeps things efficient so your energy bills won’t spike from heater usage.

Yellow Pilot Light

Traditional furnaces work by burning natural gas to produce heat. The pilot light provides the initial heat to start the reaction and usually is blue. If your pilot light is burning yellow, call a professional immediately. A yellow pilot light means your furnace produces carbon monoxide, an extremely dangerous colorless and odorless gas.

Strange Noises

Furnaces have several moving parts that can come loose and grind against one another. If you hear a loud scraping or grinding noise from your vents when you turn your heater on, it could be loose mechanical parts scraping your ducts.

Inefficient Heating

The longer your unit goes without heating maintenance, the more its performance will falter. Debris from the air might clog filters, reducing your furnace’s heating potential. Regular maintenance keeps your unit in tip-top shape so it can heat efficiently.

Cycling Too Much

Electrical components sense temperature and control when your furnace turns on. If you notice that your furnace frequently cycles from on to off, it could be a problem with your thermostat or heating element.

Heater Preventative Maintenance FAQ's

Below are some common questions about heater preventative maintenance. 

You should get heater maintenance at least once per year but ideally twice annually. The more you get service, the better your system will perform. 

The typical furnace lasts for about 15 years. However, routine maintenance can extend the lifespan of your unit by an additional five years. 

Some maintenance you can perform on your own, such as cleaning the heat exchange or replacing the furnace filters. However, you will need an expert for more involved maintenance.
