If your HVAC system shows signs of malfunctioning, you should get adequate repairs so your home can be properly heated, cooled, or filtered. If repairs aren't possible, however, you may need a replacement. According to home improvement expert Bob Vila, the lifetime of most HVAC systems is 15 to 25 years, but trouble can arise even before you hit that range. Here are some of the common signs we see indicating you need an AC replacement soon.

1. Smells

Is there a rancid smell circulating in the room whenever you turn on your AC? That's a sign your filtration system is clogged and dirty. If you keep running your AC under such conditions, not only will your house smell bad, but you may also be exposing yourself to mold, dirt, and other contaminants that cause these nasty smells.

2. Sounds

Turning on a healthy HVAC unit may come with a slight click and a barely audible hiss. At best, any sound you hear should barely register as white noise. However, if your unit begins to rattle, shake, or thump to the point where you can barely watch TV, talk on the phone, or have an in-person conversation without raising your voice, you have a problem. The motor unit or other parts may be loose, or it may be time for AC replacement services.

3. Allergic Reactions and Poor Circulation

When your unit isn't circulating clean air, you may notice your eyes begin to well up. You may begin coughing and wheezing constantly. A once-dormant case of asthma may now begin producing regular and more severe attacks. All of this can happen when you have a unit that's not circulating clean air. Poor circulation can also contribute to uneven, uncomfortable spots throughout your home. For the sake of your health and your comfort, reach out to experts in your area for HVAC services. A newer system may even be innately more efficient at keeping your air clean.

Don't underestimate the value of keeping up with your AC repairs or making timely replacements. Doing so can ensure your family remains healthy, breathing in quality air. It can also reduce allergic reactions and ensure your home remains at a properly regulated temperature.
