Steps To Clean a Furnace Heat Exchanger in Fellsmere
Although you may want to try to clean a heat exchanger in a furnace yourself, many people rely on our professionals. Our furnace technicians have the tools and know-how to clean the exchanger quickly and thoroughly for you. We will give you transparent pricing, too.
However, if you would like to try to clean it yourself, you can follow these steps.
Turn Off the Power or Gas
Before doing any work on your furnace, always turn off the sources of fuel or power. You can turn off the breaker for the furnace at your breaker box. Look for the gas supply valve and turn it off, too.
Even if you have a gas-powered furnace, it has an electrical component that supplies power for fans and circuit boards. You’ll need to turn off both the gas and electrical power.
If you’re not sure whether you are turning off the gas correctly, the rest of the cleaning process may be difficult for you to do on your own. Call our professionals for help.
Find the Heat Exchanger
Remove the access panel to the interior of the furnace. Look for the heat exchanger, which may consist of:
- Metal coils
- Curved metal tubes
- Straight metal tubes
Clean the Heat Exchanger
If you're wondering how to clean a furnace heat exchanger, start with a vacuum attachment or a wire brush. Remove dirt, cobwebs, and other debris from the area around the heat exchanger. If you notice scale and soot, you can use a cleaning solution on these areas.
Open the pipes and clean their interiors with a pipe brush and a mild cleaning solution. If you’re worried about replacing everything correctly, take photos or add labels to help you reassemble the system.
The cleaning solution will become dirty while you’re cleaning. Replace it with a new solution when you notice discoloration. If the cleaning solution remains clear, you’ve removed all the dirt and can stop the cleaning process.
If the tubes are significantly curved, you might need a power washer to remove the grime and buildup inside the tubes.
If you’re unsure whether everything is clean, use an inspection mirror for a closer look.
Replace Everything
Once you’re sure the heat exchanger system is completely clean, replace everything.

Why It’s Important To Clean a Furnace Heat Exchanger
You should notice immediate improvements once you clean the exchanger.
Improving the Longevity of Your Furnace
Keeping the heat exchanger clean reduces the need for expensive repairs and lengthens the lifespan of the furnace. Removing airflow blockage by cleaning the exchanger helps to prevent dangerous overheating of the unit.
Regular Cleaning Improves Performance
A clean heat exchanger allows the furnace to efficiently heat your home and use less energy. This, in turn, helps you save money and improves comfort.
How Often Should You Clean the Heat Exchanger?
You should clean the heat exchanger as often as once a year. If you use your furnace less often than average, which is common in the mild weather in the Fellsmere area, cleaning it every two or three years is possible.
Some signs that you may need a heat exchanger cleaning include:
- Odd smells resembling sulfur
- Soot buildup
- Moisture leaking from the furnace
Does a Heat Pump Have a Heat Exchanger?
When you have a heat pump vs. a furnace, you may wonder whether the heat pump has a heat exchanger that needs cleaning. Heat pumps do have heat exchangers that need cleaning and servicing occasionally.
Because low temperatures in the Fellsmere area are not extremely cold, our technicians see many clients who have heat pumps instead of furnaces. To keep these heat pumps operating in top condition and to lengthen their lifespans, it’s important to clean them occasionally with the help of professionals. A clean heat exchanger ensures that your Fellsmere heat pump is ready to run when temperatures dip.
