I don’t understand why people think that the house will cool down faster if they turn the thermostat down to 50 degrees.
It doesn’t work that way! I will say it again. It does not work that way. You just need to set the thermostat to a comfortable temperature setting and the air conditioner will do the rest of the work. I can’t tell you how many calls I have gone out on that turned out to just be an issue of thermostat settings. Some models of thermostats won’t work if the temperature is set several degrees different from the temperature in the house. In other words. The thermostats can tell that 50 degrees is way too low and the air conditioner won’t turn on at all. The lady we have answering the phones is good about talking customers through this. I hear her do it all of the time. But some customers don’t believe her and insist someone come out and fix their HVAC system. Other customers lie and say that the thermostat is set to 70 degrees but when I show up I see it is set to 50. Whatever. I don’t mind getting paid to turn your thermostat up 20 degrees and then waiting a minute for the air conditioner to kick on. If you want to pay a service fee for me to adjust your thermostat for you that is up to you. All I am saying is that if you really do want your house to be 50 degrees then change your thermostat 5 degrees at a time until it gets there.
