FAQs & Tips

Is your air conditioner is “running too much”?   First, check to be sure all exterior doors and windows are closed and sealed properly.

Is your air conditioner “not running” at all?    Check your fuses or circuit breakers. Let the unit cool down for about five minutes before resetting any breakers.

Your unit IS NOT “BLOWING COLD”?  Your unit may be low on FREON, either it was undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. A trained technician should fix any leak, test the repair, vacuum the system  and then charge the system with the correct amount of refrigerant. Performance and efficiency of your air conditioner is optimal when the refrigerant charge exactly matches the manufacturer’s specs, and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment.

You should CHANGE FILTERS MONTHLY As your filter gets dirtier it slows down the air flow, requiring your air conditioner or heater to work harder, therefore less efficient.  Also keep your filter grill clean and unobstructed by furniture, pictures, etc. so not to restrict the air flow to the system.  If you allow filters to become too dirty the system will work harder and the compressor or fans are likely to fail prematurely.

Is there WATER OR FLOODING around your Air Handler?  This most frequently happens when it’s humid outside.  Check the drain to make sure it isn’t clogged and is draining properly.

Steps you can try first if your unit has “ICED UP. A dirty filter, dirty coil, low on Freon or a broken blower motor is often the cause of your unit icing up.

A few steps you MAY want to trouble shoot before calling a technician is to pull the filter, if it’s dirty get a new one. Then turn the thermostat to OFF position and the fan to ON position.  Let it run a few hours, this will assist in defrosting the unit.  After the unit is completely thawed, turn the fan switch to AUTO and replace the filter.  Then turn the system back ON to COOL and observe to see if it is working well.  If it’s not…then it’s time to call a qualified technician.

FAULTY INSTALLATION, POOR SERVICE PROCEDURES AND/OR INADEQUATE MAINTENANCE  can result in leaky ducts and low airflow. IT HAPPENS MORE OFTEN THAN ONE REALIZES. Often, the amount of FREON in the system is incorrect and improper FREON charging causes poor performance & inefficiency of your unit. Unqualified techs often fail to charge properly and or fail to find FREON charging problems or even worsen existing problems by adding too much refrigerant to your already full system.
