Commonly Asked Questions About Central Air Conditioner

1. Plug on air conditioner melted and burned black. Can we replace the plug/cord- or trash the whole unit?

You do not have enough Amps to run that airconditioner in that room. This causes over heating. It is possible you just burnt up the plug.

But replacing it will just cause it to do the same again. So you need more Amps to the room. Heaver wire and breaker to the room.

Or all off but the airconditioner on that breaker to reduce amp pull. Or you may have burnt up the whole thing. Your house may be next if you do not fix the amp problem.

You also can go to a smaller airconditioner. Less amps being used. Plus there is heavy pull on the grid right now with the heat.

You may be able to cut power use in other parts of the home to leave sufficient for his air. What size off transformer do you have at the pole. How many amps to the whole home.

Do you have 30 amp service 60 amp,100 amp, or more to the home? There is a limit as to what you can pull and run in a home. On your service

my central air conditioner "freezes up" near the unit outside my home. What is the cause and what is the cure?

2 effortless products reason AC to freeze.

Too little airflow and too little coolant. think about dirt previous only the dirty filters that desires to be bumped off. decreased airflow means that the chilly fringe of the coils keeps getting less warm and fewer warm until eventually it freezes.

often, the nice and comfy temperature air might want to hit the coils, cooling the air and warming the coils. once the unit starts to ice, that makes airflow drop even more effective. once you've replaced the filters and wiped clean the unit as perfect you may without unfavorable the coils, then you really want professional help.

Too little coolant can decrease the rigidity interior the evaporator center, which finally ends up in icing. This calls for pro help. both way, it truly is time to call in a professional earlier you harm the unit with ice.

3. can you run the central air conditioning unit only with solar and if so how many panels would be needed.

How many watts is your central air conditioner?

I'm betting about 5000W. How many hours would it run, let's say 12? 5000W x 12 hours 60,000 watt hours (wh) a day, or 60 kwh (kilo watt hours) needed.

Depending on where you are, you probably get no more than 6 sun hours a day (during air conditioning season). Sun hours is different from hours of sun, it's the equivalent hours at a standard test condition that the panels are rated at. 60,000 wh / 6 sun hours 10,000 watts (10kW) of panels needed.

That's not figuring in losses or inefficiencies, it's probably closer to 13kW. Installed costs are running about $7 a watt, so you're looking at about $90,000. There are rebates and tax incentives available.

I may be way off on your load, you'd need to find out how many watts and for how many hours the A/C is on. Then you can do the math yourself.

I want to know what will be cheaper on electricity ?

It depends on a lot of different factors. For example, if you central air is not cooling right, you may have an issue with its age, efficiency or amount of coolant.

You really should get that checked first. If the house is large and has 2 stories, that will be a big factor. It will take a lot of central air to cool 2 stories, especially the upstairs, unless you have "zone" thermostats.

Finally, how many rooms of the house do you actually USE? And how cool do you need them to be? If you can deal with a warm house but want a cool bedroom to sleep in, the window AC and some fans should be enough and would be most efficient.

But if you use the entire house - a lot - and need it to be relatively cool throughout, then the 3 room ACs probably will not do the job for you and the central air would be more effecient. As long as you get it working RIGHT.

Wattage for small central air?

Like the previous poster recounted, the Kill-A-Watt device is high-quality. I've one on my laptop proper now.

Besides that, there is fairly no option to tell what is going to cost more, unless we all knew exactly what home equipment you were making use of, and exactly how long you were making use of them. Mainly, you need to be concerned with the things you utilize essentially the most. Summer is upon us, so appear into how probably you use the AC.

In the iciness time, display the heater utilization. Each of these matters are relatively able of using big amounts of electrical energy. The fridge is going to make use of quite a lot of electricity, much more so than a television or computer, however you almost always wont be ready to do so much about that except you change the fridge

I have a house without an attic. Is there a kind of central air conditioner I can install?

A tenant is authorized to do exceedingly lots something that may no longer unlawful or prohibited by way of the lease.

in the adventure that your leases do no longer handle the subject of the setting up of window air conditioners then you definately are caught with it a minimum of till the lease expires or is up for renewal. you additionally must furnish serious attention to segregating the utilities for all 3 gadgets and having anybody pay their own way. Do additionally remember that the thermostat placing on the floor floor might have little impact on situations on an top floor.

the top flooring of a house tend to run warmer for the reason that warmth rises, this is why maximum HVAC execs advise split structures on multi-tale properties. In my domicile, placing the thermostat at 22 on the floor floor will effect in temps upstairs between 28 and 30 on a warm day, so once I even have the recent device put in later this 3 hundred and sixty 5 days it is going to likely be a split device.

How does an air conditioner work?

An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling.

The mechanics of the Freon evaporation cycle are the same in a refrigerator as in an air conditioner. According to the Merriam-Webster Dictionary Online, the term Freon is generically "used for any of various nonflammable fluorocarbons used as refrigerants and as propellants for aerosols." The compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas (red in the diagram above).

This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid. The Freon liquid runs through an expansion valve, and in the process it evaporates to become cold, low-pressure Freon gas (light blue in the diagram above). This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the building.

Mixed in with the Freon is a small amount of a lightweight oil. This oil lubricates the compressor. Fairly long article.

8. what's wrong with my (central) air conditioner?

Everyone who answered is most likely correct.

A dirty condenser will deliver warmer air. But, you should be careful to turn the power OFF at the disconnect to the condenser before you clean it the right way. Turn the disconnect box to OFF or pull the breaker OUT.

You don't want the fan to come on while you are cleaning ! Unscrew the top with the fan and motor attached to it. Lift it up and turn it aside without pulling on the wires.

Remove all the leaves and dirt by hand. Use a hose with a nozzle at medium pressure and back wash the fins inside to outside for about 20 minutes. You'll get wet and muddy.

Replace the top, power back on and turn on ac. The supply air should be colder right away. If not, you'll need to call someone.

Good luck.

9. Why does the central air conditioner coil and fins in my furnace leak water to the floor?

Could be the condesate drain pan is cracked, or if it's an older unit, the metal drain pan is rusted through. The latter usually happens where the coil makes contact with the pan. The dissimilar metals react & rust out the pan.

I've seen this many times. Sometimes you can get a replacement pan, but usually you're forced to replace the entire evaporator coil which has the pan integrated onto it. The upside is that the new style pans are plastic, so they'll never rust.

Access the coil & pour water in the pan & observe where it goes. If you see it running down through the pan & not the drain, time to call a licensed pro, as the refrigerant must be removed from the system to replace the coil, definately not a DIY project! Hope this was helpful, good luck!

10. Can having a window open cause a house air conditioner to start burning?

Having a window open will NOT be the reason.

Some of the things that *could* be are dirt, age, manufacturer defect, and electrical. Keep in mind that these are just *possible* reasons, and the real reason can only be established by someone who can examine it. Dirt can get into the bearings and cause the motor to *freeze up* and some A/Cs don't even have true bearings in their fan motors.

Any defect from the manufacturing point of view *could* have something to do with it, and one of those *might* be a bad winding on the motor. Under powering it electrically may also cause the motor to fail prematurely, but there isn't much you can do about that. You power is supplied by the grid and you get what you get.

Age could be another factor, but you didn't mention that. You also didn't mention if this was a central unit or a window unit, so an exact cause can't be determined, but as for a window being open causing the motor to fail, - not a chance! Al

water leaking around the furnace when the air conditioner is running?

First check and make sure that the drain is not plugged. Bugs and things that grow will sometimes take up residence in the drain pipe outside or between the furnace and outside.

Go outside where the drain is and see if it is dripping. If it is but only slowly turn off the air and let the drain go down and the water stop dripping. Then get some bleach and pour about 1/2 cup down the drain.

Let it come out the outside. Then take a quart of hot water and dump down the drain and see if it is free. I had to do this to my AC yesterday.

Works good now. Next, look for where the water is coming out if the above is not the case. Sometimes a bare pipe will sweat a bit which is not a big issue.

The biggest thing that you could run into is that the pan is rusted our which is a replacement by an air conditioner repairman. If the water is bad do not let it continue, my neighbor had to replace the ceiling drywall due to a plugged drain.

What pressures do the high and low side run at on central air conditioners?

properly, that relies upon on the ambient temperature. The unit has a 2 ton skill.

finally, the cost might remember on the dimensions of the line set. It makes use of R22. in case you propose on working in this unit, you will need some somewhat expert kit & kit.

Please be recommended that we value greater on provider calls the place the owner of a house tried to repair it and F'ed it up. (edit) ok then, notwithstanding it variety of feels unusual that the a/c guy desires to come back returned to do a 'top off' (?).

-if thats all he's going to do then particular, you would be screwing your self. person-friendly horse experience dictates that if it desires refrigerant, it went someplace. which ability there's a leak.

The leak could desire to be got here upon and caught. base line
