No matter how new your furnace is, you don’t have to wait until it breaks down completely before taking the right steps. Professional furnace clean is demanded efficient and steady work. This article will show you the professional steps to keep a furnace clean and prolong its lifespan.
Introduction to A Professional Furnace Clean Guide
Here is simple 7 steps to keeping a furnace clean. Follow these steps to carry out maintenance on your heating system.
1. Shut Down the Unit
- Before cleaning your furnace system, turn off the fuel supply and switch off the electric power.
- The switch plate is installed at the top of the cellar stairs or near the burner. And the fuel shutoff is located at the oil tank or the gas pipe. These locations should be noted in case of fire or leak.
2. Clean the Combustion Chamber
- Fuel mixes with air and gets ignited in the combustion chamber. This leads to heat generation, water vapor, carbon soot, carbon dioxide, etc. The chamber walls can get corrupted due to soot build-up.
- A small wire brush can scrape off the build-up of carbon.
- Then you can use an industrial shop vacuum to remove loose materials. Examine the chamber for corrosion or holes before placing the cover.
3. Check the Flue Pipe
- Look out for holes in the exhaust flue or the part where the pipe is joined with the furnace. Holes can cause carbon monoxide leaks.
- If the hole is small, it can be patched with foil tape. Replace corroded flues.
- Adjust the flue pipe’s barometer damper. This part is used to control the chimney draw. A professional can help you weigh the damper to reduce the draw.
4. Replace Oil Filter
- The oil filter is a component that stops tiny impurities from clogging the oil burner nozzle. A clogged oil-burner nozzle could lead to a misfire and gets the whole system shut down.
- Now, close the oil valve, and replace the old filter with a new one.
5. Replace Air Filter
In winter, air that we breathe in the home comes through the air filter. Though it is impossible to change this too often, keep it from going for more than a year without changing it.
- Anyone can easily change the filter. You can also check out the blower’s belt wear and tension.
- A loose belt slows the blower and obstructs efficiency. If the belt deflects below 3/4 inches when you press firmly, try adjusting it by sliding the blower motor backward a little.
6. Tune the Burner and Testing Efficiency
- Set up a combustion analyser. This is used to measure furnace efficiency by measuring the gasses in the exhaust flue.
- Ensure that the burner’s air gates are tuned for an accurate flow of fuel to air.
- Replace the oil nozzle that atomizes the fuel before ignition. Also, check the flame colour and shape at the igniter.
- Whether you are using an oil or gas system, this is an indicator of complete and stable combustion. Using a gas system, use this medium to vacuum clean the burner tubes.
7. Cleaning floor Vents
- The best time to remove floor registers and vacuum the ducts is Fall. The floor register is a magnet for pet hair, food scraps, dust, etc.
- Particles minimize the unit’s efficiency. When the particles are cleared off, you will breathe easier and more comfortably.
Conclusion
Keeping your furnace clean can be a lot of work for most individuals. However, instead of stressing yourself doing this, you can hire a professional HVAC technician to be of assistance. Always ensure that your furnace is installed, repaired, and maintained by a qualified and licensed heating and cooling technicians.
