This could be 2 issues. 1 being a simple issue and the other requiring service.

First issue:

Make sure you have the thermostat on cool and not Fan.


Secondnd issue:

If the thermostat was on cool and not fan, It sounds like the freeon level is low in your system. This will cause the air to not be cold. You will need to contact your local heating and air conditioning shop and have them take a look at this. You may be low on freeon because of a leak in your system also. It is recommended you get your system checked and tuned up every year. The cost of this is usually between $50 and $90. It is a good idea because they can catch problems early on before they become larger problems. It also will also keep your central air system running efficiently and use less power compared to a system that has not been maintained. Keep me posted and if you found this helpful please rate accordingly.

SOURCE: central air conditioning blowing out hot, not

Can you tell if your outside unit is running (the fan and compressor)? Sometimes it is hard to hear the compressor for the fan. If they are running then you possibly have a low refrigerant charge and need to have some added. Refrigerant pressures and temps can be checked to verify this. If they are not running then you need to find out why. If both the fan and compressor are not running then first make sure all the breakers and disconnects are closed. Then a bad contactor or capacitor could be the problem. If its just the compressor that's not running then it could still be the capacitor or maybe the compressor.

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

What type of refrigerant should be used in a Mitsubishi ms09tw 2001 air conditioner?


The answer is R410A.

Refrigerant Types in a Central Air Conditioner
There are 2 different types of air conditioning refrigerant currently used in residential cooling systems. R-22, commonly referred to a Freon and R410A, a blend considered to be more environmentally friendly, sometimes called Puron.

R410A (sometimes known as Puron), is the industry's choice to replace R-22 in central air conditioning systems. It is less reactive with the environment while having the same home cooling characteristics of R-22. R410A is not interchangeable with R-22-you choose one or the other and your air cooling equipment is designed to operate with it. When you purchase a R-410A system, a new line set is included with your central air installation as well as a new evaporator coil. Our experience with R-410A has been excellent. New cooling systems have been dependable and efficient, as well as operating quieter! R-410A is the refrigerant of the future!

Less reactive with the environment
Replaces R-22 in the year 2020
Cannot be used with R-22 systems
Quiet and dependable
Freon, R22, heat pump refrigerant
R-22 also known as Freon has been used for decades as the refrigerant in central air conditioning systems. However it has been linked to Ozone depletion and has therefore been banned from being manufactured after the year 2010. It's price will increase as the supply decreases.

Good luck,

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

Central air conditioning system is blowing warm air.


many, many. Is the outside unit running? If it is, is the compressor running? Feel the refrigerant lines leaving the unit. Little one should be warm. Big one should be cold, probably sweating.

Tipically, a hot air furnce has exhaust and a cold air intake. My question is, why is one of them hooked to condensation pump that pumps water out?


Hello
In a forced hot air system you have a supply and a return.

Now with central air cond,you also have the same supply and return exept you also have an air conditioning coil that the return air goes through to be cooled,then it is blown out through the supply side to the vents in the home.

Since warm air or summer air contians water or humidity the cooling coil collects the moisture and sends it to a pan which when fills up is pumped out by a condensation pump.

your indoor unit is only circulating the air in the house. for your condensing unit. check your breaker in the electric panel. your contactor or your capacitor.

Central Air Conditioning


It sounds like a restriction in your ducting. Feel the A/C vents in the hot rooms to see if cold air is blowing out of them. If the ducts are restricted, then it is possible that the air conditioning coils are freezing up from lack of circulation. Inspect the ducts if you can to see if there is any restriction.

Note that even if you feel air coming out of the ducts, it could be ambient as opposed to cold. The best thing is to measure the air temperature coming out of the ducts. It should be around 20 degrees colder than the ambient air at the intake of the A/C.
