How Much Can You Save by Replacing Your Old HVAC System?

The thought of replacing an old HVAC system doesn’t occur to everyone, especially if they think it isn’t broken and there’s no need to fix it. This way of thinking can be costly for many, especially as the efficiency of many new HVAC systems can save a good amount of money. Not only that, but the impact on the environment from an old unit can be considerable compared to a unit built in recent years. Now is a great time to consider upgrading an old unit with all of the benefits that a new system could bring.

Signs an Old HVAC System is No Longer Practical

The quiet hum of a smooth, efficient HVAC system can be pleasant. But when the unit makes other noises, it may be time to consult with a pro about replacing it. These sounds may include squealing, bumping, rattling, or other uncommon noises. Also, if any strange smells are noticed, that’s an indicator that the unit requires attention.

Not as Warm or Cold as it Used to Be

Changing temperature—such as what should be hot air coming out only mildly warm, or while using the AC, it’s hard to get the space as cool as it used to be. The problem may be that the HVAC system is struggling. These issues should be addressed as soon as possible as it may be time to replace the system before it fails.

Higher Than Normal Utility Bills

Another sign of an HVAC unit not performing as it used to or should be is a much higher than usual utility bill. Higher power consumption usually indicates that the system isn’t working efficiently and may only worsen.

What Kind of Savings Can Be Expected?

The energy use of any HVAC system is determined by the demands of the locational climate of an area. Regular maintenance of an HVAC system can also contribute to its efficiency. With these variables, providing a firm number of savings that one can expect when replacing an old HVAC system is challenging.

Be sure to ask about any tax deductions or credits available when working with an HVAC specialist. These kinds of savings can add up and reduce costs right off the bat.

After the initial cost of installing a new system, the savings can usually be seen in a lower energy bill. Regular, consistent maintenance—which averages at about $100—can save even more energy costs in the long run. The overall savings can add up to what a new HVAC unit initially costs, making replacing an old system extremely reasonable.


Replacing an old HVAC system feels like a daunting task, and the best way to go about deciding what’s best is to talk with an HVAC specialist to determine AC repair Vs replacement options. If energy bills cause a moment of panic before opening them, it’s time to consider replacing that older system. The savings and potential incentives that can go hand in hand with a more energy-efficient option can save someone tons of money in the long run.
