No one buys an air conditioning unit so you can sit and do nothing but look great. Your air conditioner has a specific job to do, which is to keep your family comfortable during the hot and humid summer months. During the hot months of the year, you need your air conditioner to function properly. However, if it fails to blow cool, refreshing air and blows warm air instead, contact an HVAC technician for assistance.
Your air conditioner thermostat is the system's command center. The thermostat communicates with the air conditioner, letting it know how much cool air it should generate. It also takes measurements to make sure it is doing its job. If your air conditioning unit runs for short periods of time before shutting itself off, or if it doesn't turn on completely, this may be an indication that the thermostat is not properly determining whether the system is working or not. If you are experiencing this problem, you need a trained HVAC professional to inspect this issue as well due to the complex electrical components involved.
As with the problem of warm air, there is the problem of poor airflow. You may feel cold air when you turn on the air conditioner, but it comes out very weakly, making it impossible to circulate in the room. In many cases, this is an indication of a faulty compressor, but it may also be a sign of a problem with the ducts. Given the uncertainty of this issue, it is best to contact an HVAC technician for a tune-up. A professional has the knowledge and experience necessary to ensure there are no bigger problems in the future.
While the air conditioner is running, if you hear a grinding, squealing or scraping sound, there may be a problem with the belt moving out of place inside the unit. Contact an HVAC expert as soon as possible to avoid costly damage to other parts as well.
Your air conditioner isn't supposed to smell bad. If that happens, there's a problem. In this case, a strong odor may indicate a burnt wire inside the unit, while a musty odor may indicate mold somewhere inside the unit or air ducts. It is essential that a specialist diagnose this problem as soon as possible because this may cause you and your family to become ill.
One of the functions of an air conditioner is to reduce the amount of humidity inside your home. Even in a low-humidity climate, the air retains a small amount of moisture. If you start to notice some moisture inside your home while your air conditioner is running, the unit may need repair.
If your unit needs air conditioner repair service at least three or four times within a few months, it's probably time to buy a new one and forget about any more repairs.
Any moisture seeping into or around your air conditioning system is a problem. This may be an indication of a refrigerant leak. Since Freon is toxic, call a professional immediately. However, in less severe cases, this moisture may be water from a broken or clogged pipe that is evacuating condensation. This problem may present itself in more than one way. In some cases, you will notice water leaking from your HVAC system; While other times, ice may form inside your AC unit on the copper refrigerant lines located outside the condenser. Either way, this is a warning sign to call an HVAC professional.
Another indicator that your air conditioning system needs to be replaced or repaired is an energy bill that rises quickly without additional use. This problem could be caused by one of several reasons including a broken thermostat switch, leaks in the HVAC ducts, or the high age of the air conditioning unit. Regardless of the cause, your unit will need repair.
