HVAC systems often prove some of the most reliable systems in a home. They chug along, uncomplaining, for years. That makes it easy for homeowners to overlook or neglect them.

Like most mechanical systems, your heating and cooling will throw up some warning signs when things break down.

Keep reading for some of the warning signs that you’ll need a new HVAC system.

1. Age

HVAC systems last a long time. It’s common for them to hold up for 15-20 years or more. Once a system reaches 15 years old, however, your heating and cooling system lives on borrowed time.

It’s not a question of if something will fail, but when it will fail.

If your system gets to the 15-year mark, it’s prudent to start looking at a new HVAC system. As it approaches the 20-year mark, you should schedule a replacement.

2. Inexplicably Higher Utility Bills

Utility bills fluctuate up and down across the year and from year-to-year. The price of electricity, propane, and natural gas vary based on a lot of factors.

If you see consistently higher utility bills when the cost of electricity or gas doesn’t change, that’s a warning sign. It might only signal that your HVAC system needs some basic servicing.

Like all other machines, though, HVAC systems grow less efficient over time. There can come a point where a new system proves less expensive.

3. Humidity

When your HVAC system functions properly, it should keep the humidity at a stable, comfortable level in your home. If you notice that it’s more humid than usual in your home, that is often a sign that your system will fail soon.

This is one warning sign you should never ignore. Extra humidity in your home can encourage mold and fungus growth in your home. Mold and fungus can affect your health and even prove deadly.

4. Noise

The fans, blowers, and compressors in your HVAC system will make a certain amount of noise. As a general rule, though, that noise should mostly fade into the background.

If you find that you must speak loudly over your furnace or AC unit, that’s a bad sign. Other noises you should watch out for include:

• banging
• clacking
• rattling
• hissing

These noises can indicate worn down parts and leaks in your system.

5. Repeated Repairs

All homeowners accept the occasional repair of the heating and cooling system as the cost of owning property. The critical word is occasional.

If your system needs repair on regular basis, it’s a clear sign that it’s near the end of it’s working life. At a certain point, the repairs become more costly than a new system.

Parting Thoughts on Signs You Need a New HVAC System

As your heating and cooling components wear out or grow old, they’ll give you warning signs it’s time for a new HVAC system.

Watch out for things like high utility bills, noise, and poor humidity control. Constant repairs should tell you it’s time for serious consideration of a new system.

Of course, once your system gets older than 15 years, replacing the system becomes an inevitable certainty.
