Maintenance work to a central air conditioner’s sealed refrigeration system is not a do-it-yourself task. They should be handled by professional HVAC service experts. You can, however, do certain cleaning and maintenance tasks yourself to ensure efficient operation and keep the need for professional service people to a minimum. Before doing anything, check the warranty on your current air conditioning unit to determine whether any tune-ups, repairs or replacements may be covered.
An air-conditioning technician needs to use a high pressure vacuum to clear the drains. It should be done every year to avoid water accumulation that can cause mold growth in your air conditioner and water damage to ceilings and walls. A central air conditioner’s condenser unit, normally located outdoors, is like a large fan in a metal box with sides that look like grills. Ideally, it is protected through the winter by a condenser cover or tarp to prevent accumulation of debris inside it. Otherwise, it is likely to contain leaves, yard debris, and dirt—and that needs to be cleaned.
If you have a window type air conditioner installation or something that is mounted on the wall, examine for any physical damages such as deformed aluminum plates and coils. If these are present, you should immediately contact a professional air conditioner serviceman. Air conditioning units consume a rather large amount of electricity than most appliances, so checking the wires and cords for scratches or damages is a must. Wires can easily be conked out by pets, weather, from being tangled in other furniture and others. A broken wire needs to be replaced because they can overheat, spark and cause serious problems such as a fire.
Your air conditioning system can be your best friend especially during the hot days of summer. To keep it running well, it needs constant checkup.
