Most households don’t notice their HVAC systems. As long as their home stays cool in the summer and warm in the winter then they don’t think about it. However, when it stops performing effectively or starts getting more disruptive, homeowners are forced to evaluate their HVAC units to determine what can be fixed and what needs to be replaced. Here are three signs that your HVAC system needs to be replaced or at least needs to be inspected.   

 

There Is More Dust Floating Around

Dust is more than a cleaning annoyance. It can worsen your allergies and make your children sick. If they have asthma, they could struggle to breathe — even in their own homes. Furthermore, pollen from the outside can spread to areas like the bedroom and den that you want to feel comfortable in. Replacing your HVAC unit and cleaning your ducts can make it easy to breathe in your home again.

If you have noticed more dust in your home lately, check your air ducts to see if they’re particularly dusty. While air filters catch a significant amount of dirt and dust, older models are less effective at trapping these irritants. Your older home could also have decades of dust build up in your air ducts if they have never been cleaned.

 

Your Energy Bills Are Increasing

There are two signs that your HVAC system isn’t performing like it should: your energy bills are increasing and your system seems to run constantly. In this instance, you might have a leak in your air ducts that is pushing the air out of your home instead of inside your rooms. If your energy bills have been on the rise lately, pay attention to your HVAC system and see if it’s not turning off as often as it used to. The two could be correlated.

Before you decide to invest in a new system, call your local HVAC company for a checkup. There might be something wrong with your unit that’s causing it to run longer or push out room-temperature air. This could be an easier — and more affordable — fix than a complete replacement. During your tune-up, the HVAC professional will also check other sources around your home for leaks, like a drafty room or loose windows. This too could provide an affordable alternative to an HVAC replacement.

 

Your System Is Loud and Disruptive

Has your HVAC system grown louder in the past few years? Is there roaring and clanking that is keeping you and your kids up at night? If so, then your unit may be on its last legs. Older motors have to work harder and lose pipes or doors could lead to clanking noises.

This is another reason to have your HVAC unit inspected by a professional. He or she might be able to tighten up a few loose elements or find a way to muffle the sound of your system without requiring a complete replacement. 

A poorly performing HVAC system can make the summer miserable, whether you’re sweating through the day or sneezing all night. If you’re experiencing these symptoms, then it might be time to invest in a modern unit.
