5 Common Central Air Conditioner Problems

Central air conditioners are generally very reliable. When problems arise it's usually the result of lack of maintenance or an aging unit that is reaching the end of its lifespan.  Here are some things to check of your AC is not cooling.

Air Condioner Problems

1. Low Refrigerant Levels
An air conditioner that is running, but staying on too long and not cooling properly, may have a refrigerant leak or be insufficiently filled.

2. Thermostat or Sensor Problems
Check that the thermostat is set to "cool" and is set low enough to turn the unit on. Also ensure that the batteries are charged if the thermostat has batteries. If the unit does not turn on, check the circuit breaker to make sure it hasn't tripped.

3. Drainage Problems
A damaged refrigerant line or broken fan can cause an air conditioner coil to freeze, casing the unit to malfunction. Also ensure that the drain pan is not backed up, by clearing the drain line if needed.

4. Dirty Air Filter
Air filters should be replaced monthly or as recommended by the manufacturer. A dirty filter will cause the air conditioner to run more frequently, reducing efficiency, wasting energy and shortening the lifespan of the unit.
 
5. Leaking or Obstructed Air Ducts
Air ducts are an often overlooked part of a home's cooling system. Air duct cleaning and sealing can ensure that your system cools as efficiently as possible without wasting energy.

5 Factors To Consider When Deciding To Repair or Replace Your AC

How old is the Air Conditioner?

A central air conditioner will last 10 to 15 years. Older units are usually much less efficient and need more frequent repairs. Some older AC units will use Freon which is being phased out and is expensive.

What needs to be repaired?

Minor problems like clogged drain lines and ignitors are less expensive to repair than blower motors, condenser coils and compressors. It may be better to invest the money for expensive repairs in a new air conditioner.

How efficient is the unit?

Newer, high efficiency air conditioners can have up to 20 SEER (https://en.wikipedia.org/wiki/Seasonal_energy_efficiency_ratio) efficiency ratings, reducing energy use and operating costs significantly. If the current unit is less than 13 SEER, you can expect significantly lower energy consumption and hundreds of dollars a year in savings from a newer unit.

Frequency of repairs

If major repairs have becoming more frequent in recent years, it may be best to invest the cost of repairs in a new unit.

Is the Current Air Conditioner the Right Size?

An over-sized unit will cycle more often, be prone to early failure and have poor humidity control. A new, professionally installed system using heat gain calculations will be matched to your home's unique requirements.
