Every summer, numerous Americans are shocked when their AC units stop working, and they are left at the mercy of the scorching summer.
Don’t allow this to be you and follow the instructions your AC manufacturer and service technicians have given you. Oh, and never skip a routine annual maintenance. The technician may spot a problem which could end up breaking your AC if not repaired before it has the chance to ruin your summer.
Hughes Air Conditioning & Heating Repair technicians share the most common and the most annoying problems that people have with their AC units in the summer.
If you don’t know exactly how an AC unit works, you are no different than the majority of people whose job isn’t to know that. However, what you are supposed to know is that your AC consists of two separate units. The indoor unit actually cools your air, whereas the outdoor unit releases that heat into the air.
In order to move the refrigerant around, the AC uses a compressor pump, located in the outdoor unit. If this unit needs to work overtime for any reason, it may cause the pump to malfunction and ultimately fail.
If the air stops cooling even though the AC is on, and the fans are still blowing air, chances are that your pump has failed. Turn off the AC, and consult experts as soon as possible.
Just like any other device we have, your AC has some electrical components which may not be as durable as others.
For example, the capacitor is particularly sensitive to charge fluctuations, so if your power supply is not stable, it may end up fried, shutting down the whole AC as a result. You will notice that nothing works on your AC, despite it being turned on, so it shouldn’t be too difficult to figure out that it is an electrical problem.
The substance inside the tubes of your AC, commonly called the refrigerant operates in a closed system,and is not mixed with the air outside it. That means that, unlike in your car, for instance, this substance is not expended and it cannot run out.
It can, however, deplete itself over time by escaping through bad connections or, more commonly, through some leaks. It can start slowly, and your unit will spend longer periods of time running, but with a decreased capacity. This may be just a small annoyance at first, but it can lead to a compressor damage, not to mention how much more electricity it is wasting.
If your unit does exactly what it is supposed to do, but ends up blowing warm air into your house, this is a pretty good indication that you have a leak in the system. You can confirm it without a doubt if you notice any kind of frosting on the lines. That is not supposed to be there and if it is, you’ve found your leak.
If that happens, you will need to call in an expert to seal the existing leak, check for any other leaks or weak spots you might have missed and refill your system with the refrigerant.
Finally, if it’s not any of these things, return to the basics. It could be that the air intake is blocked, or at least obstructed, which is putting additional strain on the system.
You can start bychecking whether your outdoor unit has the necessary 3 feet of free space in every direction (don’t forget upwards). Alternatively, it may be something as simple as a clogged air filter which you have forgotten to clean or replace.
Don’t let these simple mistakes damage your AC unit and cause you unnecessary discomfort and cost.
