My AC Is Acting Strange… Is This Normal?


It may be almost winter, but in the Modesto area, that doesn’t necessarily mean much. So even as we start using our heaters a bit, you should still ask yourself how your AC system is acting. Are the things it’s doing normal or should you call your local HVAC technician? Knowing the difference between what is normal and what constitutes a service call can end up saving you both time and money, so it’s important to be aware!

For your convenience, we’ve listed some of the most common “is this normal” questions homeowners have when it comes to their air conditioning systems. Keep reading below to find out more!

“Is This Normal?”

Some of the common questions we get about AC performance is “is this normal?” when it comes to various symptoms, such as:

“My AC is pretty noisy.”

Many homeowners have experienced strange noises coming from their air conditioners, and to answer your question, this is not normal. Your air conditioner is not inherently noisy, so sounds that resemble screeching, humming, buzzing, rattling, and clanking are definitely a cause for concern.

If you hear any strange sounds coming from your air conditioner, be sure to contact your local HVAC professionals right away. A professional will be able to pinpoint the exact source of the sound in order to fix it safely and correctly.

“My AC is running in short bursts.”

This is called short cycling, and no, this is not normal. Short cycling is when your system repeatedly turns on and off without ever completing a full cooling cycle. Not only is this extremely inefficient, but it also places a lot of strain on your system, leading to sky-high energy bills and all sorts of mechanical issues.

If your air conditioner turns on and off rather frequently, it is important that you contact an HVAC professional ASAP!

“My energy bills are quite high.”

Sure, you might see an increase in your energy bills during the summer season, as you are likely using your AC much more frequently. However, if this year’s cooling costs are monumental compared to last years, then it is likely you’ve got an AC problem on your hands.

Often, high bills suggest your system is inefficient due to some sort of underlying issue. Have a professional check out your system sooner rather than later.

“My AC is on, but I am still hot.”

Your air conditioner should be able to keep up with your cooling demands. If you are turning on your air conditioner only to find that it is unable to cool your entire home, then it is time to contact a professional.

A lack of cool air can be the result of a multitude of issues, so it is important that a professional inspect your system in order to find the root cause.

Trust a Professional
