My Air Conditioner Does Not Interesting My House

If your air conditioning techniques appears to be like it does not neat your residence, this write-up could assistance you entry the problem. If your air conditioner is broken and is not going to turn on, this write-up is not going to assistance and you’ll have to go through on of my other articles or blog posts on the matter of air conditioning repairs.

To start with issues initial.


We will think that your air conditioner was sized properly for your residence, that it was properly picked based on the space you are living in, the typical necessarily mean temperature of your space, the typical humidity in your space and the relaxation of the calculations applied to identify the good heat load of your residence. If your program was undersized, there could not be considerably you can do about it, but if it was effectively sized and now appears to be as though it is not going to neat we can commence.

The initial factor you have to be completely certain of is that the indoor and out door coils are cleanse. Make certain that the condenser coil is cleanse, turn off the electrical power and bodily seem at the coils, if theres any filth at all on the coil, you can both clean them off your self or you can have them cleaned by a professional. I am not going to explain to you how to clean the coils in this write-up, only that its essential that they are cleanse. If the out door coils are dirty, then the air conditioner are not able to get rid of the heat it picks up from inside of the house.

The evaporator coil will have to be cleanse also, this coil is considerably trickier to cleanse than the out door coil, and it truly really should be completed by a professional. A good sign if the evaporator coil is dirty, is to seem at the blower wheel, and blower motor inside of the furnace, if you see dust caked all over the motor, prospects are that the evaporator coil is dirty. You will have to be certain both equally the indoor and the out door coils are cleanse.


Don’t even guess about the air filter, just take it out and adjust it. I don’t want it even a minor dirty.

Does the air conditioner keep functioning, or does it shut down.

If your space temperature is 80 degrees and you set your thermostat to seventy four degrees, the air conditioner really should occur on and keep functioning right up until it fulfills temperature. If the outside the house unit, or the indoor fan shut down at all ahead of the program fulfills temperature, then you have a problem that demands immediate focus. So make certain the unit continues to run the total time its in a phone for neat.

DOES THE OUT Door Enthusiast End Operating?

If you put the t-stat in a phone for neat, and the out door unit begins functioning, its essential to make certain that the out door fan continues to run the full time, though the compressor is functioning. If the fan stops functioning and the compressor operates by it self, your going to have major troubles. If a person did a mend to your air conditioner owing to a unsuccessful fan motor, with out testing to ensure the compressor valves are even now good, the compressor could have been broken by over heating and over pressure, you would need a professional to diagnose this.

If some one did do a fan motor substitution on the out door unit, it truly is crucial that they set up the right dimension fan motor. Its horse electrical power and RPM will have to be the very same as the one named for on the identify plate. For the reason that the pitch or angle on the fan blade was specifically intended to transfer a set amount of money of air supplied the rated motor requirements. Turn off the electrical power and seem through the grill at the motor, if you can see the sticker on the motor, look at the scores to the sticker on the side of the unit.

IF the motor has been replaced, you could be capable to seem down in in between the grill and see the wiring. If its a substitution motor you could see wire nuts connecting the motor to the wiring harness on the unit. If you see zip ties or tape on the wiring on the fan motor, these would be good indicators that the motor has been replaced. If its been replaced you have to recall that the compressor could have been broken when it ran with out the fan motor. You would need a professional to occur out and take a look at the compressor valves. If you do see the wire nuts and tape, and you do suspect that the compressor if bad its time to make a major choice as to the most efficient way to use your income at this issue. Additional about that at the finish of the write-up.

DOES THE Unit HAVE More than enough FREON?

Although you as a consumer likely don’t have the instruments to check the freon stage in your unit, you can get a good feel for the models cost, by applying a thermometer. If you have a electronic thermometer, you can turn the thermostat to neat, turn the temperature all the way down and permit it run for about fifteen minutes, immediately after at minimum fifteen minutes, just take your thermometer and evaluate the air temperature going into the return air grill inside of the house and then evaluate the temperature coming out of the source air diffuser, essentially this is measuring the air in vs the air out. I would seem for at minimum 18-22 degrees difference. It really should be 18-22 degrees cooler coming out than going in.

Upcoming go to the out door unit though its functioning, evaluate the out side temperature in just 5 ft of the unit. Then evaluate the temperature of the air that the fan is blowing out of the top of unit out side, seem for a difference of in between 20-thirty degrees in between whats going into the unit and whats coming out of the unit. If your two temperatures variances are not in between these ranges, you have a problem that demands addressing, phone a professional and have them evaluate the models cost. It could be over billed or below billed.

Upcoming just take your thermometer and evaluate the temperature of the copper pipe that has the black foam insulation on it. On a real hot day, the line really should be fairly chilly, and it could even sweat with modest water droplets on it. Make certain you evaluate the temperature below the foam so that the thermometer is not influenced by the out door temperature. Relying on the out door and indoor temperatures and humidity stages I would count on the temperatures to be someplace in the low 40’s to low 50’s Fahrenheit


 It is feasible that the primary burners on the furnace are functioning though the unit is contacting for cooling. If your house was painted and they set up the thermostat wiring incorrectly, or if theres a shorter in the electrical wiring, the burners could be coming on in a phone for neat. Make certain that there is no burner flame when the unit is contacting for cooling. If there is, you need a professional to diagnose the problem! Consider turning the gasoline shut off to the off posture, though you happen to be waiting for a technician.


The air conditioner really should be creating at minimum a dribble of water when it operates, if theres no water coming out of the condensation drain line (the white plastic pipe that will come off the indoor coil) then you likely have a problem that demands addressing. The white drain line really should go outside the house the residence some in which and drain, to the outside the house. Locate the finish of the pipe and check it for water dripping. If no water—its time to phone a professional and have them check the cost.


Make certain that the duct perform in the attic, or sub ground is connected properly and that your program is not drawing in Super Very hot attic air in the summer—THIS WOULD MAKE YOUR AIR CONDITIONER UNDERPREFORM. We just did a mend on a program in which the ductwork was broken in the attic and the unit was taking in air that was two.5 occasions larger than the space temperature. It could not maintain up with the heat load.

If any of the complications or circumstances that I described previously mentioned take place to your unit, you happen to be going to need a provider technician to occur out and check out your program. In essence the only real factor you as a residence owner can do, is adjust the filter and clean the outside the house coil. You can just take measurements but what to do with eh results will be the challenge. If you need comprehensive repairs to your previous air conditioner that makes use of R-22, its time to notice that the time has occur when it makes a lot more sense to substitute and enhance to 410A and its just that straightforward. Any important repairs to an older R-22 program are at best A Squander OF YOUR Tough Earned Dollars at this issue.

Good Luck
