If you turn on your air conditioner and all that comes out is warm air, it’s a sign your system has a problem. This could be a sign that your compressor is failing, or you have clogs in the ducts that can’t be easily fixed without the help of a professional.
1. Loud Noises
While it’s normal for your air conditioner to make some noise during its standard operation, you should not hear squealing or screaming. These sounds usually indicate a problem with the compressor, and they should be addressed immediately to avoid further damage or failure.
A whirring sound that resembles the drone of a helicopter is another sign that something is wrong with your air conditioning. The sound typically indicates a faulty fan in the indoor blower or outdoor unit.
Clicking noises, which are often heard when the air conditioner turns on and off, are also indicative of a problem. Loose parts striking against each other can lead to significant problems, so these noises should be fixed as soon as possible. These issues could require a replacement part or total unit replacement if left untreated.
2. High Utility Bills
While energy bills always rise during summer, a dramatic jump that doesn’t correlate with increased AC use indicates that your system may struggle. Depending on the problem, your air conditioner may be using more energy to cool your home than it should or could have a leak, which requires intensive repair to avoid the dangerous refrigerant leaking out of the unit.
Another indicator of a leak is moisture around the air conditioner unit. To avoid more severe problems like mold and mildew from arising, your air conditioner needs to be repaired right away if there is even a tiny pool or discoloration.
Moisture also could indicate a refrigerant leak, which is dangerous for your family. Regular maintenance, including changing your air filter and cleaning your air ducts, is the best defense against moisture and leaks.
3. High Humidity
Even when it’s hot outside, a well-functioning air conditioner should keep your home cool and comfortable. If your AC isn’t keeping the humidity down, it may be a sign of a severe problem that must be fixed before it escalates into an expensive repair bill or new unit.
Your air conditioner’s evaporator coils are designed to remove humidity by converting it into a liquid directed out of the condensate pan and into the drain tube.
High humidity can adversely affect your health, from respiratory issues to poor sleep quality. An air conditioning repair should diagnose and correct the source of your humidity issues as soon as possible.
4. Uneven Temperatures
It’s not uncommon for one room in your house to feel warmer or colder than another, but when this happens consistently, it could be a sign that your AC is struggling. Uneven temperatures are often the result of air vents being closed or blocked, which can cause unequal pressure throughout your home.
If you notice any unusual smells while your AC is running, it’s a good idea to call in an expert as soon as possible. A bad odor can indicate several issues, from burning wires to mold growth.
5. Frequent Repair Calls
If you’re calling for AC repair services regularly, it’s time to have a professional look at your unit. This will stop a small problem from growing into a big one that needs expensive repairs.
A power bill spikes up without a corresponding increase in AC usage, which is another sign that it’s time to get a technician out to examine your system. A broken thermostat switch, air duct leaks, or low refrigerant are all possible culprits.
Finally, if your unit is approaching its tenth birthday and you’ve been calling for repairs more frequently, it’s time to shop for a new one. Most AC units last up to a decade without regular maintenance and repair. A new model will save you money in the long run.
