How do I know if something is wrong with my system?
clear

There are several indicators that a system needs attention. The easy ones are when the unit will not reach the heating or cooling set point on your thermostat. Typically that means the unit is not working properly.

  1. If you have a digital thermostat and it is blank that means you have lost power to the thermostat.
  2. Check your breakers and if everything is okay with your breakers, call us.
  3. If the blower is not producing the airflow that you are accustomed to check your air filter.  Change it if needed.
  4. If you hear the unit come on and it makes a noise that you normally do not hear pay special attention to it and if the noise continues call us.
  5. If you see ice on your unit and it does not go away call us. Heat pump units will ice up but the unit should go into a defrost mode and the ice will go away.
  6. Smells are a good indicator that something is going wrong. If you smell gas or a burning smell turn the unit off and call us before you turn it back on.
  7. The appearance of your outdoor system is a good indicator of how well the unit is working. If it is clean and sounds smooth in its operation that is a good indicator that the unit has been maintained properly.
  8. If the outside unit has dirty coils and sounds rough get it serviced promptly.

About the Spring Maintenance Check: Coil Cleaning & Hail Damage
clear

Tim Panther, Interstate AC Service Technician, demonstrates cleaning coils and discusses hail damaged coils.

 

Always have a spring maintenance check before the hot weather.  Avoid having your system fail on the really hot days.  Cleaning your air conditioner’s outside unit coils is very straightforward.  First you spray coil cleaner carefully on all four sides of the coil’s fins.   Wait until you can see the cleaner foam. The foam is removing the dirt on the coils. Now use a hose with an adjustable pressure nozzle and carefully wash the foam off. The foam and dirt will quickly dissipate on the ground leaving the coils clean.  While cleaning the coils Tim inspects for hail damage.  Some units have hail guards so hail damage is not a problem. But if there are no hail guards then it is important to inspect all four sides for damage to the fins.  If the damage is minimal a fin straightener tool can be used.  If the damage is severe the coils will need to be replaced. 

You should always keep the area around your outside unit clean from dirt and especially grass clippings. Dirty coils reduce the cooling power of your system requiring more on time, more load on the compressor, and can lead to total failure of the system.  Click for more.
