If it is raining out and the humidity is rising together with the heat there is a good possibility that your air conditioning system can ice up. When it does your house will heat up quickly.
The common misunderstanding is that when your air conditioning unit is already running to turn the thermostat chillier. Do not do this. It will only make the issue even worse.
Under non damp conditions icing up your a/c system is not as typical. To spite the inconvenience it could reveal a problem that could otherwise cause your unit to require a major air conditioner service if not remedied in time.
One usual reason for an air conditioning icing up is restriction in air flow caused by a filthy filter. If this holds true You will wish to alter the filter and shut the air conditioning unit off for a couple hours. This time will enable the system to thaw. When you reactivate the AC air will move freely across the evaporator coils and continue to cool your house.
When the evaporator coil is iced over is the coils are covered with tiny lint and dust particles that cause a constraint in air flow, the other issues that we discover. This restriction happens all the time however is worsened by the wetness that is gathered however this lent and dust. High humidity exposes this problem at it’s worst. Be careful not to just neglect this issue. Chance are you are loosing around 35 % of your a/c unit’s effectiveness leading to a higher than needed power bill. Consider having an AC service done right away.
Slow blower fan
The blower fan that that is inside your a/c can in some cases slow in its revolutions. This is caused by a number of things such as dust and lint develop on the bearings or simply wearing out gradually. In either case, if the motor is still working, this can be easy to miss diagnose. Your AC was developed to have a certain volume of air blown across the coils. If the motor is working but not up to the proper speed, you could never see it up until the cover is gotten rid of and electrical amperage test is performed.
Too typically air conditioning repair technicians of Las Vegas are do not wish to climb up in the 14o degree attic so they just jump to the conclusion that the device is short on refrigerant. They keep adding refrigerant, R22 or 410a, till the unit is overcharged. In time this inappropriate resolution will cost you huge dollars.
Over Charging with Refrigerant
Over charging the refrigerant is as bad as under charging it. The system is built so that the one side of the shut system has a gas in it while the opposite has liquid. By putting too much refrigerant, R22 or 410a, in the air conditioning system, fluid is required to pass to the gas side and cause the compressor to work overtime to cool. In time this will sorten the life of your system and require costly repairs.
Too often unskilled AC professionals will avoid the proper checks of the AC and presume it is low refrigerant.
One usual cause of an air conditioning icing up is constraint in air flow caused by a filthy filter. When you restart the AC air will move freely across the evaporator coils and continue to cool your home.
Low refrigerant can likewise cause a air conditioner to ice up. Your AC was created to have a particular volume of air blown throughout the coils. By putting too much refrigerant, R22 or 410a, in the air conditioning system, fluid is forced to pass to the gas side and cause the compressor to work overtime to cool.
