3 Signs Your HVAC System is Failing You

Every driver knows the signs of a failing vehicle. A sputtering engine, a puddle of leaked oil on your driveway, or one of the many warning lights on your dashboard are just a few of the recognizable signs. But do you know how to spot similar signs in your HVAC system? If not, you may be enduring more of the Dallas, Texas, heat than necessary.

HVAC systems may not have a dashboard covered with warning lights, but the signs of a failing system are just as recognizable if you know where to look. Here are three signs that your HVAC system is failing you and needs an upgrade, repair, or replacement.

Reduced Efficiency

Is your home not as comfortable as you like? Is that Texas heat getting a little too intense? This may be one of the easiest signs of a failing system. As HVAC systems age or fall into disrepair, they aren’t able to keep up with the demands thrust upon them. A drop in efficiency could result from a number of issues in the system, ranging from a failed compressor to issues within the ductwork.

Lower efficiency will not only reduce the level of comfort in your home, but it will also cause your utility costs to spike as the system works harder to compensate for the loss of efficiency.

Excessive Dust

Have you noticed that when you run your finger along the top of that dresser, much more dust clings to your finger? This may be another sign of a deteriorating HVAC system that is linked to a number of issues. An excessive amount of dust in your home is likely a result of two things: either poor filtration or leaky ducts.

Poor filtration in an HVAC system may allow more dust and other allergens through the system than it should. If you haven’t replaced your filter in a while, your filter or air purifier could be failing you, allowing irritants into the airflow that is then distributed throughout your home. This may be a sign of faulty filtration, but it is also a sign of bad indoor air quality, which will only exacerbate other issues you may be experiencing with your system.

As a system ages, it is also possible that its duct network will begin to slowly deteriorate. When a duct gets a leak, it will pull in dust and other particles from the area surrounding the leak (such as in attics, basements, and other potentially dusty places), then distribute it throughout your home. If the leak is minor, it could easily be sealed, but if the damage is extensive, the need for an entire system replacement may be in order.

Strange Odors and Sounds

Let’s go back to our car analogy for a moment. When driving, you may start to hear some quiet clanking in the engine, or a slight odor permeating the interior of your vehicle. Many of us ignore these symptoms in our vehicles — that’s not a good idea. They should also never be ignored in an HVAC system.

Any kind of grating, grinding, clanking, scraping, or screeching sounds coming from within your system are an indication that something is wrong with the unit. This problem will not fix itself, and if it’s ignored, it will likely only cost you more time and money in the near future.

The same goes for any strange smells. If you smell a foul, pungent odor coming from the air conditioning vents, it’s possible that the wiring insulation within the system has burned out. There might be a musty odor, indicating the likelihood of mold growing in the duct network. Both issues should be taken care of immediately.
