During the hot summer months, you’ll want to have an air conditioner that’s capable of keeping the inside of your home cool and comfortable throughout the entire season. Certain mechanical problems may cause your unit to break down, and you should be aware of the signs of a failing air conditioner. Here are five signs that your air conditioning unit may not survive the summer.
Your air conditioner’s job is to produce enough cool air to keep the inside of your home from overheating, and a lack of cool air indicates a mechanical failure. A failing AC compression may be the cause of the problem. Dirty coils, refrigerant problems or a faulty thermostat are other factors that could affect cold airflow.
Sounds that often indicate a problem with a unit include squealing and grinding. If your system sounds like it’s running louder than normal, something may be wrong mechanically. Squealing noises often result from a displaced belt. If these noises persist and can’t be resolved with some simple repairs, it may be time for an AC replacement.
Having to add more refrigerant for your unit to work is a telltale sign of a coolant leak. According to Angie’s List, coolant leaks often occur in the evaporator coil or outdoor condenser coil, and usually the only way to solve the problem is to replace either of these parts. Small cracks that are causing leakage can sometimes be resolved by applying sealant, but this may only provide a temporary solution.
Unpleasant smells that are coming from your system could mean that there’s a burnout in the wiring. Foul odors are also sometimes the result of dirty coils, filtration system problems or a clogged condensate drain. If you notice a musty smell, there might be mold growth inside your air conditioner or ductwork.
If there’s a problem with your system’s power supply, your air conditioner could be on its last legs. An AC compressor that’s over-performing or malfunctioning in some other way can cause the circuit breaker to trip and cut power to your unit. If your system won’t automatically turn off after the set room temperature is reached, you should check to see if there’s a problem with the electronic controls.
It’s important to know the signs of a failing air conditioner so that you can try to resolve any problems quickly. By repairing or replacing a faulty unit, you’ll be able to stay cool when outdoor temperatures soar.
