Unit cycling on and off

"My unit will turn on and off repeatedly. What could be causing this?" When your unit is turning on and off repeatedly, you could have a problem in the unit itself. What I've seen also is the unit is too big for the house. I was in a conversation with somebody the other day and they said, "Well, you know, I got a 3-ton unit. How about I just go to like a 5-ton? Won't that cool the house faster?" Yes, it will cool the house faster, but your challenge is now Now you're not dehumidifying because it's coming on, cooling the house down, turn it right back off. On, off, on, off. The most power that unit pulls is when it first starts up. So I think Advanced Energy, when we did back with them in Raleigh a few years ago, did a study and if a unit ran for 8 hours constantly, pulled less power than if it was started and stopped, I think it was 3 times. So starting and stopping is not good for the power of that unit. It's also not good for the unit. It's kind of like I've talked about before, miles per gallon with your car. Obviously, it's more efficient for you to hop on the interstate and drive 8 hours than to spend 8 hours in stop-and-go traffic, right? You get better gas mileage out of the long trip. Your unit's the same way. So if it is cutting on and off, chances are the unit is too big for the home. And it's satisfying that thermostat very quickly and turn it right back off. It's getting cold or warm again and then it's coming back on, satisfying, coming right back off. So the challenge with that would be wear and tear on the unit as well as running up your electric bill because it's wasting energy. And when you get into the summertime, you're not dehumidifying the house properly. So you walk into some of these houses and yeah, 75 degrees, but it feels kind of clammy and sticky, that's because it's not dehumidifying properly. So when it's, you know, 30 degrees outside or 90 degrees outside, for that unit to run all day is not uncommon. Okay, it's not going to hurt anything. It's better for it to run longer than start and stop, start and stop, start and stop. Now, I would have it checked out just to make sure you're not having some kind of problem in the unit itself. But if the unit is okay, then you have to look at where it's at, the home and the duct system as well. We tell our guys all the time, there's 3 aspects to a home. There's the unit itself, there's the envelope, which is the home. Is something causing this to happen? Did I change something? Did I change a window? Did I leave something open? Are you missing insulation? You know, is something causing this to happen? And then you got your duct system under the house as well. So check all those things to make sure it's operating correctly. And if all those check out, then we have— we need to do a load on that house to make sure that unit is sized for that house properly. And if it's too large, then we can fix it.
