Importance of Maintanance free essay sample

Maintenance of air conditioning is important to prevent health and safety issues and keep the air clean and prevent break downs. Heating, ventilating, or air conditioning units for repairs entail significant costs, so it is important to avoid future expenses. Older air conditioners may still be able to offer years of relatively efficient use. However, making older air conditioner last requires performing proper operation and maintenance. Air conditioning maintenance facts HVAC system failures are caused but common dirt and dust buildup caused by neglect. With both the indoor and outdoor components out of every day sight it is easy to forget to regularly service air conditioning system performance. If the filter is not cleaned at regular intervals it may become partially clogged with lint and dirt. Operating the system without a filter allows the lint and dirt that is normally trapped by the filter to accumulate on the cooling coil of the air conditioner.

That why proper maintenance of air conditioning system required. Preventive Maintenance Preventative maintenance is essential in reducing equipment failures, corrosion and expensive repairs. Preventative maintenance programs can help reduce energy usage and save you money. Followings are packaged air conditioning system preventive maintenance procedures. (a) Air-side maintenance 1. Change filters time between filter changes depends on the type of filters, their dust-holding capacity, and the amount of dust in the air. A change interval of from 3 to 6 months will be the normal range. . Check all portions of the unit through which air flows for cleanliness and for evidence of standing water or biological growth every 6 months. Clean as required, and repair any leaks or other uncontrolled sources of water. 3. If there is evidence of biological growth, clean thoroughly and disinfect. If the condensate tray or drain does not drain completely, modify as necessary to ensure that it does. 4. Test operation of any motorized dampers clean, lubricate, adju st linkages, or repair as needed. 5. Check operation of gravity dampers; clean, lubricate, or repair as needed annually. (b) Cooling section maintenance 1. Check the cooling coil and its condensate tray and drain clean as necessary. Ensure that condensate drains completely from the tray, the drain is not blocked, and there is no evidence of biological growth. 2. If there is evidence of biological growth, clean thoroughly and disinfect. If the condensate tray or drain does not drain completely, modify as necessary to ensure that it does. (c) Gas-fired heating section maintenance . Inspect, calibrate, repair, and test fuel burners, including induced draft fan. 2. Check operation of the flue gas venting system to ensure it is not leaking, and that flue gases are not recirculating to any ventilation air intakes. (d) Hot water heating coil maintenance 1. Check coil to ensure it is clean; as required. (e) Electric resistance heating element maintenance 1. Check element to ensure it is clean; clean as required Routine Mainte nance People often think  routine air conditioning maintenance  isn’t necessary. The average person mistakenly thinks that spending money when the unit is operating properly is unnecessary, but this couldn’t be further from the truth. Followings are packaged unit routine maintenance. Three Monthly A. Supply Air Fan-Check fan and bearings for overheating, noise and excessive vibration. Check belts for wear. Adjust tension as necessary. Check flexible duct connections. Check all guards are securely mounted. B. Electric Motor-Check bearings for overheating. Check motor and drive for overheating, noise and excessive vibration. Check condition of cable, terminal box and isolator. C. Air Filters- Check condition of filter medium, frame and for any air bypassing the filter. Check the operation of the manometer. Record reading. Wash washable filters. Yearly (Y) A. Casing- Check casing for breakdown of insulation. Report any deterioration. Check for corrosion or breakdown of the paint surface. Report any deterioration. B. Supply Air Fan- Lubricate bearings as required. Check fan mountings are secure. Clean the fan impellers, casings and all surfaces where dust can accumulate. On stopping and starting, check flexible connections are not overstressed due to fan movement. C. Electric Motor- Check air passages to the motor are clear and clean of dust. D. Cooling/Heating Coil- Check and clean coil. Clean condensate tray. Check condensate tray for free drainage and flush through with a high pressure hose. E. Dampers- Check all blades are free to rotate and seal well in the closed position. Check all linkages are in sound condition. Lubricate as required and all parts for corrosion and general deterioration.
