AC Not Keeping Up? What Homeowners Should Know
As warmer weather moves in, many homeowners notice AC problems. The system may not cool like it should. It may run all day and still not reach the set temperature.
In some cases, the AC may blow warm air. It may freeze up, make strange noises, or trip the breaker. It may also cool one room better than another.
Because these problems can get worse, they should not be ignored. It helps to know what may be causing them.
Dirty Outdoor Condenser Coil
One common issue is a dirty outdoor condenser coil. The outdoor unit removes heat from your home. To do this, it needs good airflow around the coil.
Over time, dirt, grass, leaves, and debris can build up on the coil. When this happens, the system cannot release heat well.
As a result, the AC may run longer. It may cool poorly. It may also put extra strain on the compressor.
Weak Capacitor or Electrical Failure
Another common issue is a weak capacitor. Capacitors help the compressor and fan motors start and run.
However, when a capacitor gets weak, the system may struggle to start. It may hum, shut off, or run without cooling.
Electrical problems can also cause bigger issues. They can lead to burned wires, bad contactors, tripped breakers, and motor damage.
Low Refrigerant or Refrigerant Leaks
Low refrigerant is another major cause of poor cooling. In most cases, low refrigerant means the system has a leak.
For this reason, adding refrigerant without finding the leak is not a true fix. The same problem can come back again.
Over time, low refrigerant can cause the indoor coil to freeze. It can also lower cooling power, raise energy use, and damage the compressor.
Poor Airflow Problems
Poor airflow can also keep an AC from cooling well. Even with the right refrigerant charge, the system still needs proper airflow.
Dirty filters can block airflow. So can blocked return vents, closed supply vents, dirty coils, dirty blower wheels, or duct problems.
As a result, the system may freeze up. It may short cycle or run longer than normal. Some rooms may also feel warmer than others.
Aging Equipment and Major Repairs
Sometimes, the problem is the age of the system. If your AC is over 10 years old, major repairs should be reviewed carefully.
Major repairs can include a bad compressor, leaking coil, condenser coil issue, or refrigerant leak repair.
In some cases, a repair makes sense. However, replacement may be the better choice if the system has repeated problems or poor efficiency.
What a Professional AC Diagnostic Should Include
A good AC diagnostic should include more than adding refrigerant or replacing one part. The full system should be checked.
This helps find the real cause of the problem.
A proper diagnostic should include:
Thermostat operation
Air filter condition
Indoor blower operation
Evaporator coil condition
Outdoor condenser coil condition
Refrigerant pressures and temperatures
Superheat and subcooling
Capacitors and contactor
Compressor and fan motor amperage
Drain line condition
Ductwork and airflow concerns
