Per Homeowner he wanted me to call before I headed out to Gardnerville because his complaint was that his system will never shut off and just keep running and his thermostat is set to 67 degrees. He informed me that he just replaced filter, I asked him to see if the linesets were frozen inside and outside and he said NO. I had him go to the thermostat to see what the fan mode was doing and he said it was on the On position, I had him turn it to AUTO position and told him to call me in the next hour to see if it shut off after 15 minutes and to see what it did in the next hour. I told him that if it kept running that I would be out there but I never heard anything. Will follow up tomorrow with a courtesy call to see if that solved the problem
