How do I know when to replace my HVAC?

A good HVAC system will last you a long time but not forever. The real question is, “How do when I know when my HVAC system needs to be replaced?”

Here’s a few signs that might be telling you it’s time to replace your current system:

Constant Repairs

Like an older car, repairs tend to get more frequent as your HVAC system nears the end of its useful lifespan. At a certain point, the cost of a new system will actually be saving you money rather than having to keep repairing your current system.

Increased Energy Bills

Speaking of rising prices, the older your HVAC system gets, the more it will cost you on your regular bills. If your costs are climbing, this is normal, but it doesn’t have to be! If you think your costs are getting concerning, it might be time to start fresh. Though it might feel like a higher hurdle, a newer, more efficient system will save you money in the long run.

Your A/C Can’t Keep Up

Is your A/C struggling to keep your house cool this summer? It may not be as effective as it once was. This measurement is more of a “to taste” kind of preference. There’s isn’t a specific number of uncomfortable days that is the universal signal to replace it. If it’s not as strong as it used to be but you’re ok with it, then just keep it in the back of your mind. But if your air conditioning just isn’t getting the job done for you, it may be time to fix that.

Unusual Noises

There are a lot of things in life that make strange sounds when they’re not quite right (cars, knees, kids…). Your HVAC system is on that list. A pleasant little hum is a good thing, but if you are hearing any kind of mechanical grinding or scraping, that is definitely not what you want to hear. These noises tend to increase with your system’s age. You may not need a whole new system, but you may need to consult an HVAC expert to see if it’s an easy fix or something more serious.

Asking “What is that smell?”

Nobody likes a bad smell, let alone one that is being circulated through the whole house by your HVAC system. But be careful, if your HVAC is a little funky, it may be more serious than just a smell. Your HVAC might have developed mold! This can happen with something like your furnace if it hasn’t been used for a couple months. This should be a top priority as it can put you and those in your household at risk of getting perpetually sick. Just remember, though it may be an urgent need, don’t forget to look for special deals that can help make your unexpected expense a little lighter.

Lack of Circulation

Lack of air circulation can be a little bit harder to identify. Sometimes, the air in a room might just feel or smell stale. Another sign is that certain rooms in your house might be significantly warmer or cooler than others, indicating insufficient air flow to certain rooms. This isn’t as dangerous as something like mold, but it may affect air quality and increase allergic irritations.
