My Central Air Conditioner Unit Is Freezing Up and then Won't Cool...is This Caused by Humidity?

It is likely that your air conditioning unit is low on freon. This causes what you refer to as 'freezing up'. I would stop running the unit and have it checked by a professional.

You could do harm to the compressor if you allow it to run in this condition which would be very costly to repair

Air conditioner does not recycle during the night.

get a fancy thermostat that has a humidity setting. I got a new carrier ac/heat pump this year, it came with a carrier tp-prh-a thermostat.

it has a humidity setting. If the temp is satisfied but the humidity rises it will run the ac and set the inside fan to a low speed to take the humidity out of the air.

stop the air flow of a central air conditioner from a specific room?

You can close the vent half-way, not all the way. Central air is designed for your whole house with vents open and closing one will do three things. Back the air up in that duct to the fan and making it work harder.

Waste cold air. Allow the return vent to draw in warmer air from your room and make the supply air to all the other rooms warmer

Problems with brand new air conditioner and thermostat?

I hope you got more that a 6 month warranty on a new installation.

If you did call the installing company and tell them to get back out there and fix it. If you did not it is almost certain you are dealing with a shabby company that originally installed your unit and their entire installation could be wrong. Dealing with reputable companies, not always the cheapest, is essential in HVAC installation

how much does it cost for a central air conditioner?

Figure on at least a few thousand dollars. But, like the first person said, there are too many variables to determine for sure on our end. Call an air conditioning company and have them come out to give you an estimate.

They have to do a heat load calculation on your house to determine what size compressor you need before they can quote a price

New central air conditioner stopped blowing cold air, help?

If the system is under a year old-then this is a warrenty issue. You can check the circuit breakers to ensure they did not trip, and make sure your thermostat batteries, (if it has them) are not low or dead.

Other then that, anything you do could void your warrenty-call the installing contractor or the seller and let them fix it under warrenty.

How to refill Central air ?

thats a tuffie.

you need a license to buy r-22,you need a set of guages,if the unit has never been serviced you may need a torch and silver solder to install a schrader valve,a vaccuum and recover unit and some leak detection equiptment.you be better off trying something simpler like kidney stone removal as it requires less equiptment

------

Is our central air conditioner working properly?

which fan.

inside or outside. if outside fan is running then yes your using ac. if its the inside fan running then you are just circulating inside air.

kinda helps on reducing hot places but will cause the elec. bill to go up. it also filters the inside air.

dont forget to replace your air filter often. flip your switch from on to auto

------

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

Why not just buy a solar Air conditioning unit?

They have tubes that heat up the freon so they only need a smaller compressor using less electricity, then you would only need less solar electric panels on the roof too. Lennox makes a central AC unit that has the inverter built in and takes care of the connection to the house and grid, all you need is the solar panels

------

What percentage of total kilowatt hours is consumed by a electric fan in a central air conditioner?

Not near enough information.

The condenser takes by far the most current, but it cycles on & off, while the fan runs continuously. (One would have to know the cooling load.) The current used by the air handling fan is governed by the ductwork it must move the air through, (varies widely from one installation to the next).

------

Where is the filter on a Central Air Conditioner?

It will be adjacent to the air handler, and accessible from inside the home. Find the handler, not the exterior compressor, and look on the interior wall closest to unit.

This unit should be in garage, sometimes in the ceiling if you have a drop ceiling. If it is to far to be coming out an interior wall than it will be at the base of the unit itself

------

My home central air conditioner turns it self on while the montier is on a off mode.

Is it the a/c or just the fan?

As you may know that the fan for heat comes on by a thermostat built into the unit. So if your attic is very hot, the heat may trigger that fan to come on thinking that the heater is on and the plenum is hot enough and the fan runs.

------

will a dehumidifier work like an airconditioner?

It will only remove moisture from the air and not heat. Less humid air may feel cooler. A thermostat will read the same temperature with or without the humidifier.

Weather reporters give us a temperature and a humidex. The humidex (humidity index) is an estimate of how we perceive the combination of temperature along with the humidity in the air. The Muse

------

Should my attic fan still come on when my central air is on ?

Yes it should come on if the thermostat tells it to come on. Most attic fans these days have a built in thermostat that controls only the attic fan it is attached to. It would have nothing to do with your central air conditioner.

Remember that heat rises and it may get hotter quicker in your attic than in your main living areas

------

  Why does it take my air conditioner many hours to cool off again, after I turn it up, and turn it back down again?

Yes yes your are unless you know how to use a multimeter to check voltages an capacitor an amp draw of compressor.  An gauges to check refrigerant.

From what you say sounds like possible your compressor isn't kicking in all the time hence the hot air probably cause because you air handler is in the attic.

What size central air conditioner needed for a 1400 sqft house?

Hi Robert, Properly sizing an air-conditioner is very important.

In most of the country there is a rule of thumb that you would need one ton for every 500 to 700 square feet. There are other variables such as insulation, ductwork, and windows. Ultimately the decision should be made by a qualified contractor.

If you have any other related questions please let me know

------

Should you run a dehumidifier while the central air on?

If your basement is exceptionally damp it is fine, plus you probably don't run the AC 24/7. I know I don't run it when the weather is cool for a few days.

Having the dehumidifier in the basement is no problem. When the AC is not used it will keep the basement dry. I do the same thing

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

The outside unit is not getting 24V to the contactor for one reason or another. Look around the unit where the refrigerant lines run from the unit into the house. There should be a small cable run along the lines.

The cable would have at least two small wires in it. See if there is a break in the wire. Is the indoor air handler running?

BEARING OUT ON AIR CONDITIONER! HELP PLEASE!?

HVAC Tech.: Don't run it shut it off! You have a bushing in the blower motor gone bad and is allowing the squirrel cage blower to drag against the housing.

When the motor over heats and kicks out you could do serious damage to other components of the system. Call a repairman and have the minor problem fixed and avoid the major one!.

------

I have central air do I cover the system ?

yes you should cover but not air tight. The unit will not run all winter and many times the fan will freeze which can cause the motor to burn out.

In the summer the fan runs enough times to keep it free. In the winter snow sits on the motor and cause corrosion and rust. Make sure the fan turns freely before you turn the AC on in the spring

Question about Central Air Conditioners?

See details?

If you turned the breaker on, maybe the installers put a disconnect on the outside of the house by the unit. Make sure it is turned on.

Turn the t-stat to cool and fan auto and turn it down. I would think they ran the unit to try it out after they finished the installation. Hope this helps!

Good luck!.

do portable air conditioners work?

they are rather weak. most of them are not strong enough to cool off an entire apartment. likely you will have to close the bathroom door, bedroom doors etc, biggest thing to make sure of is that there are no leaks (no open windows, no open door cracks, no where for hot air to enter and cool air to escape

------

central air conditioner?

The only time the compressor should stop running is when the thermostat's temperature is reached. The compressor compresses the refigerant and it is sent to txv valve or orifice that greatly reduces the refigerant temperature. This how the refigerant gets so cold.

As the residence gets warmer the a/c kicks inagain and starts the whole process over again.

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

The bushings interior the motor are drying out.

close the ability off,take the panel off and spray wd-40 on the decrease component to the shaft and manually spin it.placed the panel back on and initiate it up and you're able to nicely be waiting to purchase some extra time till finally you replace the motor. good success.

incredibly saturate it with wd-40 and it will in all threat paintings

I have central air and the air conditioner is running but the air is barely working. What should I look for?

You should look at the filters in your air conditioner to see if they need to be replaced or cleaned.

When filters have a dust buildup on them the air will have a hard time passing through. You can all call a technician because you central air condition could need a good cleaning or freon. You can go to this site to see if this will help

------

Why does my air conditioner keep freezing up?

The unit is freezing up because the load is too heavy or the temperature is set too low. An A/C unit is only supposed to cool the air a bit. You may want to add a dehumidifier as well if your weather is humid.

Your A/C shouldn't be set to less than 72 so 68 is far too low, which explains the freezing. 72 is a very tolerable temperature for dogs.

------

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

HVAC Tech.: Your Pressures are those of a system in peak running condition. Temperature will effect them but not to much.

As it warms up the head pressure will rise more rapidly than the suction side. A word of caution for what it is worth. It is ILLEGAL to access the refrigerant lines with out proper certification, BE CAREFUL!

Does it cost more to turn off your air conditioner when it is cool outside, or to turn up the air?

you will possibly have a partly clogged evaporator coils, or clear out. besides the incontrovertible fact that this is plenty extra possibly the unit is low on Freon.

you could verify the clear out your self. seem on the evaporator and notice in case you notice dirt build up on the fins. yet you're probable going to ned an AC tech to envision the cost point of the unit

about central air conditioner size?

You want it to cycle that way.The minutes you stated are very good and normal.If it were running continuously and not shutting off,that would be a sign of trouble.

If you are going to replace it,look into a 3 ton 14 SEER Goodman. They have excellent warranties and are extremely competitively priced compared to other brands. Good luck.
