When you have a central air conditioning system for your house, you expect it to … well, cool the house. You set the thermostat to a comfortable temperature, and after about ten minutes, you should have the level of cooling necessary to keep your household happy.
So when an AC is running but not able to deliver the comfort it should, it’s a problem.
But … what kind of problem?
We have more than 40 years of experience working on repairing air conditioning systems in Malvern, CA, so we’re the people you can turn to for the help you need to get your cooling system back to work. Below we’ve listed some of the reasons you may have an under-performing central AC.
Clogged Air Filter
This is the most common source of a low-cooling air conditioner. Thankfully, it’s an easy one to correct and may not require calling for professionals. The filter located in the HVAC cabinet must be replaced with a clean filter every one to three months or the trapped debris in it will throttle the airflow into the air conditioner. The less air enters the AC, the less air is cooled and sent into the ventilation system. Change the air filter and see if this improves cooling—and remind yourself to change the filter regularly through the summer.
Faulty Thermostat
When your house won’t cool down enough, you’ll probably spend some time adjusting the thermostat to attempt to overcome it. But the thermostat may be the source of the problem. A simple miscalibration that causes the thermostat to misread the temperature will throw off home cooling. The thermostat may have lost its connection to the AC, or have failed programming. Technicians can repair or replace the thermostat to fix this.
Leaky Air Ducts
The air conditioning problem may be due to the ductwork responsible for distributing cool air around the house. The ducts can develop leaks over time, and this allows the cool air to begin to escape from the ventilation system before it reaches the room. This not only means less cooled air getting to rooms, but a drop in air pressure throughout and ventilation system that affects the entire house. To fix this, you must have professionals test the ducts and seal the holes.
Short-Cycling
This is symptom of a number of different problems in an air conditioner. When the AC can’t complete a full cooling cycle and instead turns on and off in quick cycles, it won’t have enough time to properly cool the house. This could be due to a clogged air filter, leaking refrigerant, a dying compressor, or a number of other issues. HVAC professionals must diagnose the problem first and then find the right remedy.
Undersized AC
If the air conditioner is new, the problem may be that the system was badly installed—it’s too small for the house. In this case, the only solution is to have professionals (not the people who originally installed the AC) to replace the system.
