How To Clean A Furnace

A furnace is a device that circulates warm air around your house to provide warmth. It generates heat through the use of electricity or gas and distributes it through ducts. To keep your house cozy and warm, it's important to keep your furnace clean. The buildup of dirt, dust, and debris within your furnace over time can make it work harder and not as effectively.

Poor heating effectiveness, increased energy costs, and even costly repairs can result from this accumulation if it is not cleaned on a regular basis. The benefits of regular furnace cleaning are many. It lowers heating expenses and saves energy by making your system operate more efficiently. Eliminating dust and allergies from the air is another way that a clean furnace improves the quality of the air in your house. Additionally, it makes sure your furnace operates reliably and smoothly when you need it most.

Step-By-Step Cleaning Guide

Safety must be your priority before you begin cleaning your furnace. Here is a simple step-by-step guide for cleaning your furnace:

Step 1: Switch Off The Power And Disconnect The Fuel Supply - For safety, switch off the furnace's power before doing any cleaning. This can be done by unplugging the furnace from the outlet or by switching the switch next to it. Then off the fuel supply. Look for the gas line valve next to the furnace to see whether it is powered by propane or gas. Completely stopping the gas flow requires a quarter turn of the valve. For the cleaning process to be safe, this stage is necessary.

Step 2: Clean The Furnace Exterior And Combustion Chamber - First, remove the furnace access doors. Use a screwdriver to loosen the screws on any burner covers, then carefully remove them. The furnace's base and burners should next be cleaned using a professional vacuum or the upholstery attachment on your standard vacuum cleaner. To get dirt and debris out, make sure you reach into every little space you can. Pay attention to any dust accumulation when cleaning. Dust is an indication of poor combustion, which may require inspection and repair by an expert. Your furnace will operate more smoothly and safely if it is cleaned properly.

Step 3: Take Out The Blower Motor - You will need to remove the control panel if it is blocking the blower motor's path. Carefully unscrew the panel with a socket and ratchet set. The blower motor can be securely removed to clean it after the panel has been removed. For your furnace to be properly cleaned and to continue operating at its best, this step is necessary.

Step 4: Gently Clean The Blower - Pay close attention to the wiring and fan blades when cleaning the furnace blower. Use a small bristle brush to clean places that are hard to reach and a vacuum to remove any dust and dirt. A dirty blower might become imbalanced and impact the furnace's functioning, so be sure to clean it thoroughly. Additionally, check for damage or holes in the ductwork and any accessible air ducts. Resolving any problems early on ensures the smooth and effective operation of your furnace.

Step 5: Clean The Flame Sensor - Locate the metal rod, which is your furnace's flame sensor, and carefully remove it from its mount. Clean the sensor lightly with an emery cloth to get rid of any debris or accumulation. Slide it back into position after cleaning. It's important to clean the flame sensor because a dirty sensor can prevent the furnace from lighting up correctly. Maintaining your furnace's highest efficiency requires routine cleaning.

Step 6: Lubricate The Fan Motor - Your furnace will require oiling for its shaft bearing and motor bearings if it is older (approximately 15 to 20 years). First, take off and wipe the oil covers. Next, give the bearings a couple of drops of lubricating oil, being careful not to apply too much. After finishing, reattach the oil caps. This should be performed once a year to maintain good operations. Lubricating your furnace is not necessary if it has a more recent brushless motor. Avoid adding oil to these self-lubricating motors as it could harm them and cause them to burn out.

Step 7: Clean Or Replace The Air Filter - Cleaning or replacing the air filter in a furnace is one of the simplest maintenance tasks. Simply replace the filter if your furnace has a disposable one. Remove any reusable filters and give them a thorough cleaning. An unclean filter can reduce the efficiency of your furnace and possibly stop it from generating warm air. Maintaining the health of your furnace can be achieved by frequently replacing or cleaning the filter.

Step 8: Turn On The Burners - Power and gas must be turned back on before the furnace burners can be turned on. The heating will then begin when you turn up the thermostat's temperature. Check the flames after turning on the burners. They need to be steady and blue. The burners are unclean and require cleaning if the flames are yellow. A professional should manage this because it requires specialized knowledge and attention.
