How Much Does It Cost to Change a Furnace Filter?

Many homeowners opt for high-end models due to the overall savings potential and less maintenance involved. The boiler fan motor controls the air flow throughout the house all year round, while the cooling system relies on the fan motor to keep it cool during the warmer months. Your oven burners channel open flames that provide heat to your home, but you may need to replace them at some point during its life. Soot can clog burners and prevent them from igniting, in which case your HVAC technician may only need to clean them to get the oven working again.

A circuit board acts like the brain of your oven, as it starts the heating cycle when the thermostat sends heat signals. When circuit boards fail, it's usually due to humidity, so if your oven is located in a part of your home that receives high humidity, adding a dehumidifier can help protect it. The draft inductor is a motor that controls the flow of air inside the furnace. The flame sensor is a safety feature that monitors if the burners are lit, and if they don't light up, it ensures that the gas valve closes, preventing gas from accumulating.

But because it's frequently exposed to open burner flames, it picks up soot and may need to be replaced if it gets too dirty. During the home heating cycle, the oven burners heat the heat exchanger and the blower motor pulls air over it, which heats the air and circulates it throughout the house. An intelligent valve is a type of gas valve that is equipped with its own circuit board, but they are only incorporated into a few furnace models, making it difficult for your HVAC technician to find a replacement. If you don't change your furnace filter regularly, particles will cover it and not as much air will pass through.

This can lead to more extensive repairs such as replacing the air cleaner motor, which will cost more for parts and labor. A new oven can last several decades if cared for, but not replacing the filter regularly can shorten its lifespan. Knowing when to change your oven filter can be confusing, but regularly replacing it will help your HVAC system last longer. It's also an accident that many of the things the filter prevents from entering your HVAC system also improve the air quality inside your home.

If you live in a larger house, there is a lot more air moving through it and you may need to change the filter more often. Not many homeowners set their calendars for furnace filter replacement, but it's an essential step in keeping their heating and cooling system in top shape. With the exception of some labor-intensive repairs, the cost of a repair will generally depend on the cost of the replacement part.
