One of the biggest misconceptions associated with air conditioning units is that they tend to break down too often. In actuality, the fault lies within the owner’s maintenance schedule, not in the units themselves. Timely AC service and maintenance are key variables that determine the life of a unit. The following are a few maintenance tips that will ensure the maximum life of your air conditioner.

Cleaning or Replacing the Air Filter

Most of the problems associated with air conditioning units such as inefficient cooling, high noise levels and dust throwing can be rectified by simply cleaning or replacing the air filter. Air filters tend to last anywhere from one to six months, depending on the season. During high use seasons such as the summer months, reusable filters should be cleaned at least once a month, preferably with an air blower as contact cleaners can cause damage to the surface lining.

Oiling Mechanical Parts

AC units are composed of several mechanical parts and motors such as the compressor. Like all moving parts, they are susceptible to wear and tear due to friction. Regular lubrication is necessary to assure proper functioning; lubricants such as WD-40 and lithium grease are recommended. Also check for cracks or any other irregularities within the compressor motor blades, replacing them as necessary.

Checking the Internal Circuitry

While it’s a rare occurrence, the internal circuitry may also malfunction due to extreme temperatures melting the insulation on the wires. To check for fried circuits, remove the outer access panel and see if any of the wires display signs of burning or charring. Vulnerable parts include circuit contact points and the condenser switch.

Before you start with the maintenance however, make sure to turn off power to the air conditioner. This can be done by switching off the main breaker panel in your house.
