Air Conditioner DIY Maintenance

Posted on The Cooler Blog March 31, 2013

Heating and cooling make up at least 40% of the average person’s energy consumption. In reducing the electrical bills and raising efficiency, proper A/C maintenance is essential! You don’t want to replace an air conditioning unit due to neglect. Taking these steps in maintaining your system can help avoid the repairman when you could have prevented the problem beforehand.

How To Perform Maintenance On Your Air Conditioner

  1. Check the controls. Make sure that the A/C unit starts, operates, and shuts off properly. It’s vital to repeat this habit.
  2. Check your settings. Time the A/C to your schedule. A timer that turns off when you leave and restarts before you return is an ideal investment.
  3. Check the drain. A plugged drain will cause water damage.
  4. Lubricate. Any un-lubricated moving parts can increase friction and the amount of used energy.
  5. Tighten all connections. Bad electrical connections are unsafe and can damage your unit.
  6. Measure voltage and currents. Faulty currents can reduce the durability of major components.
  7. Adjust blower components: This provides better airflow; related problems can reduce efficiency by 15%.
  8. Change air filters once a month. A dirty filter reduces efficiency and the life of the A/C unit.
  9. Clean condenser and evaporator coils. Dirty coils cause the system to run longer because the system cannot function as well.

Running the air conditioner this summer can be a necessity, so make sure it’s working efficiently. Reducing your unit’s energy consumption is good for your wallet/carbon footprint and the planet.
