What is Air Conditioner Short-Cycling?

Short cycling of the Air Conditioner, means that you hear it coming on, and off too frequently. A normal cycle would be for the air conditioner to come on, and remain on for 10-20 minutes and then turn off. Often with a short cycle you will also notice that it is not cooling your home, because it is not running long enough to achieve the desired temperature. What could be the problem?
     Have you changed your filters lately? One reason for short cycling is, filters being clogged to the point that air can’t move freely through the system. In Boise and Meridian, filters should be changed at a minimum of twice a year.
      Here is what to do. Turn off your air conditioner at the thermostat, Open up your furnace and clean, and vacuum all that you can see. Change the filters, and then turn the air conditioner back on. It may not come on immediately, so wait a minute or two and see if it comes on and runs through a normal cycle.
      If the fan in either the air conditioner OR the furnace seems sluggish coming on, or seems to turn slowly or makes a growling noise, you may have fan bearings going out. If this is the case, you need to call Greens Heating and Air, and have one of our technicians perform a diagnostic check to know for sure what the problem is. The coil on your A/C may also be clogged with dirt and grass. It is called the ‘Condensing Coil’ Again call us!  There is also a coil attached to the top or bottom of your furnace. It can become clogged as well. It is called the ‘Evaporative Coil’. We highly recommend that you sign up for our Preventive Maintenance program, where we come out twice a year and clean, check and tune up your equipment, along with changing the filters. We call this our Peak Performance Agreement.
