I Have a House Without an Attic. Is There a Kind of Central Air Conditioner I Can Install?

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.

Need some advice on how to trouble shoot central air conditioner.

Your discription is a little vague but it sounds like it could be the transformer or one or both of the capacitors. If your Tstat signal isn't getting from there to the contactor on the condensing unit, it won't start and that could be a bad transformer.

If the signal is getting thru to the condensing unit and the contactor is engaging without chattering, then there is a problem with the compressor, fan or capacitor(s). Is there a hum when the unit is supposed to be running? Is it silent, with no noise at all?

The hum is a sign that the compressor isn't starting or the fan motor isn't starting. If the fan motor won't go the compressor will build too much head pressure and shut itself down by blowing the breakers. This is very bad for the compressor.

If there is no noise at all from the unit, then the signal isn't getting thru form the Tstat or there's no power to the Tstat so someone needs to check the output at the transformer to see it you've got the 24v the circuit needs to operate. This forumn isn't designed for back and forth questions so I hope you can figure it out from here. If not, don't take a chance on ruining your compressor.

It's the heart of your A/C and it's expensive to replace but that isn't a very good idea, not as good as replacing the whole unit. Good Luck John

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

I am trying to determine what size central air conditioner I need for my home?

Go to and read:www.energystar.gov/index.

cfm Then, Get three estimates no more try a big private franchise look in the yellow pages, then try Sears and someone that has been in business for a long time especially the company that makes the unit. You,ll know the companies that have been around for decades. I don't want to guesstimate this as there are variables that i can't compute as I'm not there.

Each area may have a different major A/C central system maker available. It's a good time for a new a/c Try & do it while the Obama energy credit still exists with many stores sales on top of that from state to state you have to check. I know a easy way is to have a Company like Sears give you a site estimate they will usually give you three prices for a regular better and best grade unit.

Except for bells & whistles "you should go by the efficiency rating the best Eff. for cost of operation. The best that you can afford even if you must pay some interest to buy the one that suites your cooling costs do it, I'm certain you can handle the decision buy the highest efficiency unit.

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.

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!

Nashville air conditioning repair with payment plans?

3,000 simoleons for a busted central air unit? Wow.

The new unit must be manufactured by Gucci or Prada. Tell us what you are having done, if it's a pretty big system or they are changing out the air handler and A-frame along with the outdoor unit, it could get up there. I'm just curious what this 3,000 bucks is paying for.

For work that major, get lots of bids and in the mean time go get a window unit for the bedroom you sleep in. Are you positive that the unit can't just be fixed? ------------------------- Read the edit.

Mismatched? OK.all that really means is that either the air handler is pushing too much air for the A-frame and vaporization is taking place way too quickly or the air handler isn't moving enough air and the A-frame is getting liquid loaded.

If it's the later situation, you could simply put on a TXV or EXV (you could even install a VFD on it that would be way less than 3 large). Pray tell, is either unit properly sized for your given condition? Is either unit actually broken down?

Which is bigger (capacity-wise), the air handler or the outdoor unit?

Central Air Units froze up?

This icing situation is led to by fairly some issues.

One is as suggested earlier, destructive air flow around the evaporator. The evaporator is the factor on suitable of your furnace you spot icing up. verify for a grimy clear out, unfastened belt ot different obstruction such because of the fact the coil itself being grimy.

yet another reason is a "low load" situation. that is led to whilst the return air is merely too chilly. Your evaporator runs approximately 40 tiers chillier than the air for the time of it to take in the warmth.

If the return air is seventy two or decrease, you're freezing the evaporator. it's going to be working at 32-30 degress. Water freezes at 32 and the moisture interior the air isn't something yet water.

to repair this, attempt to no longer run the A/C so low. additionally, there's a shortage of refrigerant. (that's the perfect term, 'Freon" is in user-friendly terms a form made by DuPont, you dont call each motor vehicle a Mustang do you?

) in case you have a sluggish leak, it is going to must be pinpointed, repaired and the unit will must be evacuated and recharged. this might must be accomplished by a professional. each little thing else you're able to do on your very own yet i might easily turn the mode on your t-stat to "OFF" and your fan to "ON".

this might soften the ice on your coil. After an hour the ice could be thoroughly melted and the evap could be dry. then you could do the tests
