Keep the Calgary Furnace Running Properly
calgary furnace repairs maintenance can be categorized into 2 methods, called the periodical maintenance and the preventive maintenance. In the first type, you may follow the DIY procedures to clean the parts, replace the oil and lubricant, remove the rust, test the working components, and replace the external accessories and screws, etc.
Preventive maintenance needs professional approach. Here, the furnace expert inspects and scans the external and internal parts of the furnace. He identifies the potential points of failure which may grow into critical damages. He repairs or replaces the parts depending on the technical feasibility and durability factors.
By implementing the two maintenance methods, it is possible to enhance the lifespan of the furnace by many years for safe and efficient functionality.
Periodical furnace repair maintenance is a process in which the various parts of the furnace are inspected for defects, calibrated (whenever applicable), and lubricated and cleaned. In some cases you may have to replace the defective (minor) parts whenever it is required. You need to inspect the furnace at least once in three days to ensure the proper functioning without any unexpected breakdown. You can also prepare a checklist of the cleaning and lubrication tasks with the help of the furnace technician or the engineer who visits your home during the installation.
You can perform the simple cleaning procedures for the parts including the filter, heat exchanger, air ducts, vent, blower, coils (electric furnace), and other non-critical components.
The filter location in most of the standard furnaces is in the front panel. Turn of the furnace and unscrew the panel refer to the maintenance manual to locate the filter. It is the rectangular or square shaped carbon coated fiber material. Before removing the filter from its location, you need to check the accumulation of dirt, dust, and other macro level deposits within and around the tracks. Use an air blower or vacuum to remove them. Then you can take the filter out. Use mild detergent or soap in the ratio of 1:4 with moderately hot water in a bucket or a tub. Immerse the filter into the water and let it soak for 10 to 15 minutes. Then you can use a cleaning brush to remove the dirt deposits. Make sure you don’t damage the filter or cause scratches. If it is not possible to clean, it is better to replace it with the new filter. Screw the panel.
Heat Exchanger Cleaning
The heat exchanger is located beneath the flue vent and behind the front panel. You can see it once you remove the two components. The looping of the metal tubes in multiple rows and columns forms the exchanger. Check for the deposits of dirt, soot, and dust. You can vacuum or use the air blower to remove them. Also check for any deposits of rust on the exterior surfaces. Use a metal brush or a sandpaper to gently take out the rust only. Make sure you don’t cause any scratches to the heat exchanger surface. Use a dry and soft cloth to take out the rust deposits. In the next step you can remove the rust band dirt deposits from the base of the exchanger. Finally you can vacuum and rub the exchanger pipes with the dry cloth.
Rust removal is a process which covers the metallic internal parts that can accumulate it from exposure to the heat, humidity, vapor and water. You can use the antirust spray for the removal. You have to soak the rusted part in the spray for a few minutes, before taking the rust out using the brush.
You can also use the mechanical methods like the sandpaper, grinder, or the sanding machine. Make sure you don’t leave any visible marks or scratches on the heat exchanger coil. Using the sprays and the long handled brush is useful when the rusted parts are located within the furnace interiors.
After the rust removal and cleaning, it is necessary for you to lubricate the rust prone metal surfaces, joints, screws, and the other complex parts. You have to pay special attention to the parts like the furnace blower, flame sensor, motor and the other moving parts. Make sure of lubricating the screws, tube joints, and the other connecting parts.
Motor lubrication requires motor oil. Apply it to the ports and the belts, joints and the other visible parts. You have to avoid application of excess lubricant as it can cause loose contacts and lessened tightness of the belts and screws. Similarly, you can also lubricate the blower, bearing, cushion, and the other connecting parts. Some forms of the motor may have a grease cup which empties after consistent usage of the motor for many years. You don’t need to replace the grease every month or week. But you should keep checking the levels regularly.
Preventive maintenance is also a regular task for ensuring the smooth running of the home furnace. But it is specific to the parts and the sub-parts of the furnace. Tightening of the loose screws, calibration of sensor and other electronic parts, and repair or replacement of the failing parts are some of the tasks covered in this category. The best practice is to take the help of the furnace repair and maintenance professional. He will have access to the latest technology and tools for carrying out the diagnosis and analysis tasks. He can diagnose many types of microscopic defects before they grow into critical damages.
Visual inspection is good for the exterior parts of the furnace and the interior parts which become visible when the expert opens the casing. panel, etc. He will be able to detect the loose screws, missing bolts, rusted joints, cracked pipes etc. This procedure helps in the efficient repair and replacements.
Ultrasonic scanning can display the hidden or internal defects and damages to the components and parts. A hairline crack within the interiors of a pipe can develop into large size cracks with time. Preventive maintenance procedures by the furnace repair and maintenance experts can protect the furnace and the surroundings from critical damages.
