Homeowners were concerned that they’re new system was short cycling. They timed 3 cycles at 4, 10, and 7 minutes. I checked turned the thermostat down 1° and then cycle lasted 8.5 minutes. It came back on sometime later and ran 6.5 minutes to maintain the temperature. The average cycle time is about 10-15 minutes. Although ambient temp right now was 73°, I explained the when the weather is cooler like it is now the unit will have shorter cycles and that normal. I asked when they seem to notice is short cycles most often and Mrs Jackie mentioned it seemed to do it most in the evenings. Which at this time of the year our outdoor temp cools in the evening to the point where you they not even need to run through the night and will have shorter cycles.
