It can be hard to imagine a hot day in Houston without AC. By April, we’ve already got temperatures in the high 70s / low 80s. With all the rain, it can be stifling and humid if your cooling system fails unexpectedly. Here are five common reasons why your Air Conditioner Isn’t Working according to the federal Department of Energy.
1. Your refrigerant is leaking.
Ideally, you want your refrigerant charge to match the manufacturer’s specification. A leak can cause your system to struggle to perform, not to mention harm the environment. Unfortunately, you can’t simply add more refrigerant. You’ve got to call a trained technician to repair the leak, run a few tests, and charge the system with the recommended level of refrigerant.
2. Your system is filthy.
Air conditioners are much like automobiles. Just as you need to have the oil and air filter changed every so often, you need to have your AC’s coils and filter cleaned regularly. Otherwise, the dirt will overtax your unit and cause the compressor or fans to fail prematurely.
3. There has been an electrical failure.
Over time, parts like the compressor and fan naturally wear out — especially if you’ve never had them cleaned or when you’ve purchased a system that is too large for the space it is cooling. These units turn on and off frequently all day long. Corroded wires and components are often seen in older models, so it’s good to have regular service calls to detect any issues before they become a major headache.
4. The sensor is out of position.
Sometimes the sensor gets jostled and knocked out of position, so it has a hard time measuring the air temperature coming into the evaporator coil. This can cause your AC to act erratically, cycling on/off too much or too little. Fortunately, this problem can be corrected by straightening the wires and the sensor device.
5. There is a clog in your drain.
Clogged drains can shut down your system in a hurry. Regular routine maintenance will prevent this common issue.
