If you want to make sure that your home is always going to be as comfortable as possible, in terms of the temperature on the inside, you will need to make sure that you are fully aware of the signs that tell you that there is trouble brewing within your central air conditioning system. If you spot any of the following troubles, you will need to immediately call an HVAC contractor for AC repair.
Banging Sounds Are Becoming Very Noticeable
It is normal for there to be a little bit of noise coming from your central air conditioning unit. However, it really should not be much more than just a humming sound. The humming sound is the result of the motor working and the fan rotating. What you want to pay attention to is any banging sounds that you might hear. The longer you wait to have an HVAC repair technician take a look at the unit, the louder the banging sound and the problem may become.
The Home Is Not Evenly Cooling Off
This could be a problem with the central air conditioning unit itself, or it could be a problem with the ductwork that feeds the cool air throughout the home. You won't be able to know for sure until you have a skilled technician check it out for you. You will want to make sure that this problem is checked out as soon as possible. If it isn't resolved quickly, you might find that you have to make your air conditioner work harder just to get the interior of your home to a comfortable level. This will not only be a strain on your air conditioner, but it would most likely cause your electric bill to increase substantially.
The Lines From Your Air Conditioner Are Hot To The Touch
It is one thing for the lines to warm up a little because of direct sunlight. However, if this is a problem even after the sun has gone down, you will want to turn off the central air unit and call for a reputable HVAC technician in your area. The sooner you do this, the sooner the electrical components of the AC unit can be inspected and replaced as needed. You don't want to brush off the problem and simply assume that everything is fine. Doing that could result in your central air unit shutting down or catching on fire.
Whether you spot one of these signs of trouble, or something else that just doesn't seem right, you will want to call for professional help right away.
