No one buys an air conditioner so they can sit back and look good. An air conditioner has a specific job to do, which is to keep your family comfortable during the hot and muggy summer months.
Your climate control thermostat is the command center of the system. The thermostat communicates with the air conditioner, communicating how much cold air it should generate. Plus, you take steps to make sure you're doing your job.
Similar to the hot air problem is a problem with weak airflow. You may feel fresh air when you turn on the air conditioner, but it comes out very weakly, making it impossible to circulate around the room.
While the air conditioner is on, if you hear grinding, squeaking, or squeaking, there may be a problem with a belt slipping out of place inside the unit. Contact an HVAC expert as soon as possible to prevent costly damage to other parts as well.
An air conditioner should not smell bad. If it does, there is a problem. In this situation, a strong odor may indicate a burnt wire inside the unit, while a musty odor may indicate mold somewhere inside the unit or in the ductwork.
One of the tasks of an air conditioner is to reduce the amount of humidity inside your home. Even in low humidity climates, the air retains a small amount of moisture.
If your unit has needed an air conditioner repair service at least three or four times in a few months, it may be time to buy a new one and forget about any more repairs.
Any loss of moisture in or around the AC system is a problem. This may be an indication of a coolant leak. Since Freon is poisonous, contact a professional immediately.
Another indication that your AC system needs replacement or repair is a rapidly increasing energy bill without additional use. The cause of this problem could be one of many, including a broken thermostat switch, duct leaks in the HVAC system, or the age of the air conditioning unit.
If your air conditioner is at least ten years old, you should be thankful that it has lasted this long and start shopping for a new appliance. Air conditioners generally don't last more than a decade.
If any of these 10 signs occur, contact a professional HVAC technician. Trying to manage repairs yourself can incur unnecessary costs if something goes wrong.
