Air Conditioning Maintenance Tips

Question:  How often should I have my Freon added to my Air Conditioner?

Answer:  Your air conditioner does not consume refrigerant (Freon) as a car consumes oil, so under ideal conditions, it would not be necessary to change or fill.  Therefore, a low Freon level indicates a leak that needs to be repaired before adding more. Most new system connections are welded to minimize leaks, many older units (over 8 years) , however, were connected with mechanical flared fittings which can vibrate loose over the years, causing leaks.

Freon Leaks are a problem because:

  1. The efficiency of the air conditioner is effected by low Freon levels.
  2. Low Freon level or leaks can cause the evaporator coil to freeze, causing it  to literally ice up.
  3. Freon is an EPA controlled substance, deemed hazardous if released into the environment.
  4. The compressor, which is the central component of the air conditioner,  is cooled by the refrigerant. Over time, low Freon levels can cause overheating and premature failure of the compressor, often requiring complete replacement of the compressor or possibly the entire condensing unit – a very expensive project.

Things homeowners can do to maintain their air conditioning units:

  1. Check to make sure the condensing unit located outside is not covered up, before turning on your unit. Obstacles, such as stacked lawn furniture, bag of leaves, lawn clippings around a unit over the winter can hinder the unit from being able to draw air into the system creating a problem because it has to have something to circulate inside in order to cool.
  2. Remove any covers that may have been placed on the outside condenser.
  3. Run your air conditioner for a few minutes in late spring or early summer, before you need it, making sure that it is indeed working.  This could be a blessing in disguise to prevent being caught off guard and be stuck in the heat longer than you would like waiting for an available service specialist to come and fixit.
  4. Filters should be changed regularly.  Dirty filters restrict air flow, reducing the efficiency of the unit and in worse cases can cause the evaporator to ice up.  Electronic or Electrostatic filters need to be washed regularly. Disposable fiberglass filters should be replaced.
  5. Be sure all access panels are secure, with all the screws in place. Clean obvious obstructions such as newspapers and leaves from around the exterior of the unit.
  6. Be sure the thermostat has been set in the cooling mode.  Just setting the dial below room temperature will not activate the air conditioning if it is still set in the heat mode from the winter season.
  7. Homeowners are strongly cautioned and discouraged  from using a water hose to try to clean their unit because of the very serious risk of electrical shock and possible shorting of the electrical components. It is recommended to have a seasonal cleaning and system check before starting the new season by a trained specialist.
