I am in the Houston Texas area and am looking to get an idea of how long you guys in other very hot areas are seeing your AC's run on a daily basis? My electric bill shows what I consider to be a very large amount of power usage, and the only thing I can think of is that my AC's are running more than they used too to account for it.

They are really the only device in the house that draws a significant amount of power, and changing the thermostats on them over the winter is really the only thing that has changed since last summer. Just curious, thanks in advance! Tags: None. August 1,PM. I live in south MS and it is unbearably hot lately.

The outside temperature has been in the upper nineties for a few weeks now. During the day, the setpoint is higher, but on weekends it's set a couple of degrees lower. Comment Post Cancel. We've noticed what appears to be "brownouts" in the midwest at peak energy usage times. I 've not seen this since the 90's. It seems to even out the temperatures some. The cycling from what I can tell is a bit less looking at the Omnistat 2.

Typically during the summer months the electrical usage is higher along with the monthly bills. Not gonna say more other than my wife likes the temperature of the MB and Family where its at My neigbor is currently having an issue and I think its more related to the design of his AC; as his home is about the same age as mine.

He's having problems keeping a 78 F even temperature in his home; and his AC is working just fine. Outside temps here have been mostly in the upper 90's.Remember Me?

How many hours should the AC run during the hottest days of the year? Here in South Carolina my AC ran in minute cycles most of the time last August hot and humid time of year. In the evenings it would run much longer cycles but averaged about 9 hours per day. My data is from my Ecobee thermostat. Should it run in longer cycles and more hours of the day if properly sized? Thanks for your help! Runtime should increase with outdoor temperature until you get to design temperature, when the unit should run constantly.

Originally Posted by rider Yes, that is short cycling if it is the hottest day of the year. Nit a whole lot you can do about it, except plan to get a smaller air conditioner next time around.

That would be short cycling. What town are you in?

What is the humidity inside the house? At those temps listed your system should be running constantly or dang near. The design temps here are 95F and 26F. That means at 95 your system should be running all the time. And make a cold, wet cave out of your house. So if the AC is sized for continuous running when the outside temp is 95F, what happens when it's 93 and we have company say 12 people over and we are cooking out so people are going in and out.

Doesn't sound like it would keep up then. Where is the sweet spot? Originally Posted by jmed Locate site members HERE! Questions should end with a question mark "? BALloyd liked this post. Originally Posted by kdean1. How many hours in a year will you have company and be cooking out?

Answer: not enough to justify oversizing the equipment. Lower air flow removes more moisture and slows cooling rate. A small whole house is one way to remove moisture during non-cooling hours. Keep us posted.In the dog days of summer, AC is a necessity. But it can be a complicated necessity. How frequent and how long your AC cycle runs will depend on four things:.

It might seem obvious, but the hotter it is outside, the more your air conditioner should be running. It needs to work much harder than usual in order to keep your home cool. On days that are warm, but not unbearably hot, your AC should run less. In warm weather, your AC cycle should run every 15 minutes or so.

On a very hot day, your AC should run a lot. But if it is literally always running, you might have a problem. The air conditioner is probably too small for your home, or it is not working properly.

You might have a refrigerant leak or an airflow issue. But if it runs for too short a period of time—say, for about 10 minutes at time—you might have an oversized AC. Plus, if it turns on and off more frequently, the parts will wear out quickly, and that means more frequent repairs and a shorter lifespan. Ideally, your AC should run for 15 minutes on nice, warm days.

Only on those rare triple-digit temperature days should your air conditioner be running almost all the time.

Posted in Uncategorized.Maybe your air conditioner seems to be cutting on and off too frequently, or maybe it seems like it never turns off at all.

Either way, you may find yourself wondering—is this right? How often should my AC run, and how long should it go before it turns off again? Well, the answer depends on a few factors. It is designed to run at maximum capacity when the temperature outside is hottest. On those sweltering degree summer days, your air conditioner should be running almost continuously. This holds the temperature inside your home close to the setting on the thermostat.

This could be due to a refrigerant leak, an airflow problem, or some other mechanical issue. On the other hand, when the weather is milder, your air conditioner should run less of the time. In mild weather, a correctly sized and functioning AC will run in cycles of about fifteen minutes each. This is approximately two to three times per hour.

That might seem like a good thing—too much AC is better than too little, right? And in our muggy Tennessee Valley summers, dehumidifying is especially important! So, your air conditioner should run for about fifteen minutes at a time on mild days and almost constantly on the hottest days, all while keeping your home nice and cool. Search for: Search.

how many hours should ac run per day

Just curious I'm near Ottawa and yesterday's temperature was around Celsius and my central AC started at like 9am and didn't stop until 8pm. I've set it to 23 degrees and during the day I saw I have a 2 levels square foot house with a lot of windows.

I believe my AC unit is 20 years old and 2. I know my unit is old, probably not strong enough but I'm curious to know what's normal. A - When was the last time you or hired help cleaned the exterior unit? The little metal fins used to dissipate the heat will get clogged up with dust and junk, diminishing the unit's efficiency. B - It seems to be doing pretty well for the heat wave we're having. How's your humidity? C - To answer your original question: A properly sized AC should be runing almost always in this hot weather.

You want the AC to have the time to dehumidify your air. I did clean the exterior unit last summer bought the house in June and it was clogged. I should do it again I also need to clean the air filter at the furnace, I've heard that could help also. As for humidity Other than running all the time, it feels comfortable in the house, I really can't complain.

However, it is often at times like this, when there appears to be a much higher than usual chance of a power failure in the neighbourhood. I could thrive on the heat myself, and my little dog can take a lot, but will usually wilt before me.

I had a quick question.

how many hours should ac run per day

Home is around sq. It's difficult to determine how long it's been on since we have an ecm motor and it tends to go on cruise control so it's never on high speed unless it's been turned on for the first time and the outdoor condensing unit tends to shut off several times throughout the day yet cold air still comes out the vents. I adjusted the dip switches so low speed is around rpm.

We keep the house at around degrees F. The furnace fan regardless of what temperture it is outside it will never run on high once it's reached around 74 degrees and normally runs at around rpm on days like today. If I were try try to estimate how many hours the outdoor condensing unit runs in a 24 hr period with outdoor tempertures over 30 C I'd say maybe 6 out of 24 hrs. My attic fan however runs around 12 hrs per day and I have the attic thermostatic set to 90 F and will usually turn off around pm at night.

The second floor temperature is also at 74 F. I personally love the heat, but hate humidity and we tend to have lots of humidity in the GTA. My AC runs for the most part of day as I have big and too many windows in house.

Living room has double ceiling height and also have roughly 18 ft X 4 ft X 2 windows on one wall. My nest thermostat says the AC has run between 4 hours to 10 hours a day over the last two weeks Toronto.

My condo is sq feet, I'm on the top floor of a 6 floor condo. My condo has 4 big windows and they all face east during the day which means sunlight all day long.Some people worry their air conditioner runs too much. In a perfect situation, an air conditioner should run for minutes at a time in mild temperatures. Any less than that and your AC could be too large for your home — more on that below.

The hotter it is, the longer your air conditioner has to run to reach your desired temperature. This is especially true when the humidity is high. The lower you set your thermostat in summer, the longer your air conditioner will have to run to reach it. The biggest factor in air conditioner run times is the size of your air conditioner. An air conditioner that is too big will decrease your run time to around 10 minutes or less.

This is called short-cycling, and it means your air conditioner cools your home too quickly. Short cycling also impacts the percentage of humidity in your home. That means you still feel hot and sticky. An air conditioner that is too small will do the opposite. Anything over 20 minutes with little to no change in temperature means that your air conditioner might be too small. However, a neglected air conditioner does the opposite.

This is bad for your air conditioner and bad for your electricity bills. A larger home will take a little longer to cool, especially if the air conditioner unit is on the small size. Instead, close off the dampers and doors, and redirect that air into your family room.

Your home needs insulation all year round. A lack of insulation means that much of the air you spend your hard-earned money on cooling is actually leaking into the outside world. This means it takes much longer to cool your home, and your air conditioner will run longer to compensate for the loss. Long story short? Buying the wrong sized air conditioner will waste your money, lead to more repairs, and impact your comfort in your own home.

July 6, Air Conditioning. An Air Conditioner Should Run for Minutes at a Time In a perfect situation, an air conditioner should run for minutes at a time in mild temperatures. There are a lot of factors that impact how long your air conditioner runs, including: 1. The Temperature Outside The hotter it is, the longer your air conditioner has to run to reach your desired temperature.

The Setting on Your Thermostat The lower you set your thermostat in summer, the longer your air conditioner will have to run to reach it. The Size of Your Air Conditioner The biggest factor in air conditioner run times is the size of your air conditioner.
