5 Signs You Need a New HVAC System

Increased Running Time


When your system gets old and requires a replacement, you’ll notice that it starts up more often. It might also stay on longer in order to reach the desired temperature.

It can be caused by bad coils as well as a failing blower motor. So check these parts before ordering a new installation.

If your coils and blower motor are fine, then these are signs that your HVAC system can no longer produce and circulate the air in your home efficiently. As a result, it requires more time to reach the desired temperature.

If, even after repairs, your system runs for a significantly longer period of time more often than it used to, it’s time to replace the unit.

Loud Noises


It’s normal for older HVAC systems to get louder with age. But when you notice that the following noises, it might be a sign that you need a replacement:

  • the blower is humming louder
  • the outdoor unit is making more noise
  • the furnace is groaning and banging
  • noise before the air conditioner starts up

Some of these noises can be explained by a loose part or a part that needs to be replaced. Others may be related to problems with fans, motors, blowers, and other moving parts. But if the odd noises increase or remain after repair, it’s likely that it’s time to replace your system.

Lots of Repairs


A lot of the individual parts in an HVAC system are repairable and replaceable. But all HVAC systems will eventually wear out and require complete replacement.

And when a compressor, motor, or coil fails, replacement is far more worth it than repairing. The cost of parts, as well as labor for repairing these essential components of your system, are high.

While the upfront cost of an entirely new system seems like a lot, the cost of constant repairs when one of these parts fails isn’t worth it in the long term. That money is better invested in an entirely new system. And when you get that system, be sure to have a professional help you maintain it to extend the life of your investment.

You Don’t Perform Regular Maintenance


Most people don’t realize the importance of performing regular maintenance and checks on their HVAC system. Checking your HVAC system at least once per year ensures they’re working safely and efficiently.

Maintenance helps you catch problems before they lead to bigger issues. It keeps your system in the best working order to increase its lifespan. If you don’t perform regularly scheduled maintenance, it’s more likely that the problem has reached a point of no return.

If you notice a dangerous pilot light situation, frayed or exposed wires and conduits, or other visible damage, your HVAC system may actually be posing a safety risk in your home.

Your HVAC System Is 10+ Years Old


If you maintain your HVAC system properly, it might last you a little longer than a decade. Without maintenance, a 10-year-old HVAC system is considered outdated, inefficient, and a good candidate for replacement.

Beyond the 10 year mark, you can expect an HVAC system to start costing you in repairs. They’ll also cost you more in energy bills as they lose efficiency.

Even the most state-of-the-art technology from 10+ years ago doesn’t come close to matching the energy efficiency of today’s systems. Newer units also have digitized and programmable thermostats that are easy to use and help make your home smarter.

Why You Should Replace Your HVAC


The initial cost of an HVAC system is high, but there are many ways you benefit from a new system. In case you need some convincing on the initial investment, we’ve listed all the reasons you should replace your HVAC when the time comes.
