Feb 27, 2010 Do not operate at a maximum power for more than 30 minutes. For continuous operations, do not exceed the rated power. For example their E6600DE is 6600 watts peak, but 6000 continuous (which is still quite high because normally continuous is 50-60% of peak) with a running time of 7.4 hours at rated load. Nov 17, 2017 Duty cycle: The duty cycle of almost all two-stage air compressors is 100%, which is one of the reasons they are viewed as being more powerful and durable. This duty cycle indicates that the compressor can run nonstop, without needing time to cool down. In contrast, most single-stage air compressors have a duty cycle of 50% or 75%.
We went on the advice for size for both from the heating and air wholesaler we purchased our central ac units from. Our home is approximately 1600 square feet and we have 13 registers. We also purchased a new thermostat.We've never had Central air conditioner before.
Our new central ac unit runs constantly during the heat of the day, usually from about 2pm till 9pm in the evening. Granted, it's been hot here, mid 90's and the heat index higher. Do we have a problem or is this normal?My husband thinks our duct work may be too small for our new central air conditioner system.
Our home was built in the 60's and we used our existing duct work. Thanks so much for any help you can give me. Ratingmany things to consider NEWby: DavidAny of these will cause your AC running non-stop and not to keep your set temperature:1. Your air return window (grille) is too small. 3.5 ton AC needs 700 square inches of air filter area.2. Dirty air filter3.
Blower in furnace must support 1600 CFM (1 ton of AC need 400 CFM)4. Attic air leak. You need to climb up there and seal all air leakage passages. I sealed 14 small and large attic air leaking spots in my house.5. Large window facing West should be covered with blind and/or tint them with head control film6. Weak insulation attic.
Adding more insulation if it is too thin up there.7. Round duct size should be 18' or more for 3.5 ton AC. RatingCentral Ac Run All The Time NEWby: TommyVickie & DandanI have the exact same problem. I live in an apartment and the maintenance guys are stupid. They tried to tell me it should run constantly. My bill has double and I know it will be more next month.
It runs from 2:00 to about 8:00pm. They replace the unit twice but still the same problem where the AC runs constantly for those time frame. I have decided to research it myself and find out what the issue maybe. My thermostat is set at 76 but during the time frame above the temp reaches from 78-80 on the thermostat.
I thought it had something to do with the oven being on. I say that because I noticed when it on the temp goes up on the thermostat, which is expected if oven is on for long period of time but the oven is only on for about 10-15 minutes. The theory when out of the window when I left the oven on for about two hours and nothing happened. I will continue to search for a solution and post any update that might be useful. RatingHelp NEWby: DineneTurned my air on, it ran for three days without shutting off.
Ran constantly. I turned it off and tried it again today. My thermometer I taped up near the thermostat reads 78 degrees. The Thermostat reads 70 and it is set at 78.
It Has been running non stop for 5 hours now. It is not cooling down hardly at all. Landlord sent some here today and he said he put Freon in it. I now this isn't right to run this long and the different temperatures on my thermometer and the thermostat. My bill will be outrages! Why if it is set at 78, reads 70 and runs so long not cooling down.

RatingGood A/C Unit vs. Old Houseby: B.E.K.Many of the houses built in the 60's as yours was had little, or no insulation at all. I've found this to greatly affect the heating, and cooling of these structures. Also, if you are using the original, rigid metal heat ducting then 1.-It is too small. 2.-It probably doesn't have any insulation left on it which means that it WILL be super-heated by the high heat in the attic, will sweat (alot!) - this can eventually cause sheetrock damage, wood rot, mold, or could provide a nice damp area for termites. You might have purchased a good (or great)air-conditioner system but, need to seriously focus on your home. GET A PROFESSIONAL INSPECTION - QUICK!!!
RatingA/C runs all the timeby: woodFirst check the T-stat setting. If it is set way below the actual air temp.
It will continue to cycle a/c unit until set temp. Is achieved at T-stat. In your house does not cool efficiently there could be other problems associated with your cooling system. Condenser sizing, supply and return air duct sizing, dirty coils (indoor and outdoor coils), check air filter for clogs and excessive dirt build up, this can cause return airflow problems. Indoor coils can be clogged with dirt not allowing air to flow through coil to remove humidity and air to pass through cold coils.
Check TXV adjustment and proper placement of bulb. Duct sizing is imperative to system efficiency. Refrigerant levels determined by superheat at outdoor coil. Low refrigerant (FREON) can cause indoor coil to freeze up so air cannot pass through coil. The A/C system is integration of refrigeration and air flow with many components that must operate efficiently.
For example indoor fan speed changes from cooling to heating. Hire an experienced HVAC service tech. That is how you will get your $$$ worth. RatingRuns all the timeby: AnonymousA properly sized AC unit would run constantly during times of maximum load.
Check the thermostat.If actual temperature is still above your set point, then the unit should be running! Once it reaches the set point at some point it should start to cycle on and off.But on your hottest days, it should be mostly on. If your unit cycles during lower demand times, then it is probably just fine. If the actual temperature is below your set point, then there is something wrong.It is just as important to have an AC unit that is not too large as too small. Too large and the AC will drop the temperature, but not have time to dehumidify and you will feel 'clammy'.Air gets dehumidified by the air flowing over the cold coil and water condensing on the surface of the coils. When purchasing a modern unit, a unit that allows you to set humidity as well as temperature will save a great deal of money, because you can set the humidity low, and be just as comfortable at a higher temperature.Well worth the extra cost (is actually a bargain), and you will be more comfortable. If your unit is sized to run continuously on the hottest days, then it is sized right and should be doing a good job at humidity control.
RatingCentral Ac Run All The Timeby: DadanHey, VickieI’m not sure what you meant by “all the time.” If it run nonstop, that is not normal. It normal for central ac unit to run and stop for like 8 or 18 minutes and then it come back on. (8 and 18 minutes is made-up number, sometime it less and other time it more.)I had seen this thermostat that had hold button. This button allows your central air conditioner to run nonstop until something causes it to stop. I don’t recall the thermostat branch.
Thisthermostat is digits screen by the way.Had the contractor look at the ductwork? I can’t tell you if it too small for your new central air conditioner units. It not normal for central air conditioner unit to run nonstop, until you had this thermostat.Regards,DadanP.S come back here if I didn’t answer your question correctly.
Been living on a 6.5kW generator for the last three days now up here in middle New Yorkthe generator - a Yamaha gasoline engine on a Homelite portable wheeled chassis - has been running almost nonstop for about 60 hours now, with only about 10 minutes of downtime this morning when it ran out of fuel. Other than that we have been refueling it live. It was bought a year ago and prior to Tuesday it had maybe 12 hours on it since new. As far as we know, the load is well within the continuous output capacity of 6500 watts.what i would like to know is, will it hurt or put excessive wear on anything to have this run for another 72 hours? Should the machine be allowed an hour or few hour break? How often?the electric utility company says its going to be at least a few days longer due to the weather getting worse as the week goes on.
When I was in the Army and we had to run off generators in the Field- It was customary for us to shut off power every 6 hours to check the oil and air filter as well as to fuel them up. (these were diesel though),But you should probably read the manual.
And occasionally shut it down to check the oil and air filter as well as to refuel. ( I would say every 4 - 6 hours to check the fluids then let it sit for at least 10 min ) not to mention if the belts are visible then check them. (some have chains and those you have to make sure are lubed). Not to mention you should see if there are any lube points- though probably you are snowed in and don't have a grease gun.If not then look online for a manual- usually they have a general maintenance section.Also to note make sure that it is in a well ventilated area.Though after this period of use you may want to consider getting the oil changed in the generator as soon as the weather clears. I'm positive its 6500 continuous watts.
No worries there, i know the difference between peak and continuous output. By the sound of the gen outside, we aren't even getting close to the continuous max for more than a little while at a time.i am more worried about the engine really, but at least its cold, not hot, out there right now being the middle of winter so it won't overheat or anything. I will see about checking the oil tomorrow, something we forgot about really.
As for shutting it down every few hours, its not going to happen with my family. Dad dumps gas into it while its running as it is.the manual is long hidden away and i'm not going outside to find out the model. It seems to be holding up well.the power definitely isn't clean, the blower in the furnace is a tad quieter (and slower) and the incandescent lamp in our fridge has a noticeable flicker depending on the load.
But it seems to be holding up well. It powers enough of this household to keep all 4 of us happy.
Energy efficient integrated florescent light bulbs (the 15w kind that screw in to replace regular 60w bulbs) are used in all other light sources and they operate just fine.its connected to our mains box with a cable that provides two leg power (2x120 or 240 volts). We are careful as to what is running. So far its lighting, two small televisions, a 3 month old fridge, a trailer-sized oil burnig furnace from the 70s that is running about 60% of the time, cable modem and router, three laptops plugged in and powered on, a water pump hooked to an underground well, and for a short time this afternoon, my Oki LED page printer. If we kill the heat, the water heater can be run, usually for 30 minutes or so at a time we give it.same with the clothes dryer.
No light dimming here, though i wish i had a P3 Kill-a-Watt handythanks for the replies, im going to sleep now:). Not sure what a gen like that can handle but whole home ones are greatconnect right to your power and it auto switches on when the power goes out. Nice to have them and they run off natural gas so no refillingdad is thinking of a 12000 watt diesel for a future upgrade, as it would be more than enough to power.everything. we normally use. Natural gas would be nice, but i think he'd go for diesel because it could easily be hooked into our heating oil tank and would burn slightly cleaner for a cheaper price per gallon than standard road vehicle diesel fuel.all else: turning off the heat for an hour makes the place pretty chilly, but the fridge temp creeps up to 50 degrees which isn't good for our food.
Tomorrow we plan for a two to three hour break.and about the noise? There are at least 5 generators running on our road at any given moment, although i think we might be the only ones running one constant. First off why do you need to run a freezer 24 hours per day? It is winter outside and you could put the stuff in a cooler and leave it outside unless of course the temperature is above freezing. Second of all that is why it is always good to have a wood burning stove in situations like that where power could be out for days. Luckily during the ice storm about 12 years ago it was only for a stretch of 8 hours that we were out but had constant loss of electricity.Turning the heat off for an hour makes the place chilly?
You probably have lousy insulation if that is the case and to save energy should put on more clothes. Sheesh talk about panzies. When our power went out because of the wind storm in the Midwest, we ran our generator 12 at a time, and never had any issues except the noise.
I used good quality fuel and Castrol oil, with some Jacobs added to the gas and oil. It worked great. We had 2 freezers, and a refrigerator, and they were fine with only 12 hours a day. The trick is to keep the freezers covered to keep the cold in. We had no power for 6 1/2 days.We are planning to get a whole house generator, Costco has a 10k NG/PG unit (12k PG) that comes with auto 100 amp switch box (it will cover up to 150 if you upgrade), which is more then enough to power my house.
It can handle most homes, and only cost $1997.99. It is a little larger then an air conditioner, but something that i plan to get, (the batteries for my UPS are getting to costly).

Aren't your powerlines underground or something? I know a lot of snow has fallen, but really, a few days without power? There would be riots if something like that happened here, no one even has a generator over here:Dnah over here in America our power grid is old and unreliable. Very newly built areas usually have utility lines underground and inner city areas of course have all wiring, fuel, and water lines buriedbut not out in the woods where i live, here everything is suspended in open air on poles.147000 customers in the dark is the power co's estimate as of last night.
