Should You Repair or Replace Your HVAC System? Here’s How To Know

Repair or Replace HVAC System Charleston SC

If you’re living in a home long enough or have owned a rental property here in Charleston, odds are good that you’ve experienced your fair share of HVAC issues.

Just as sure as you’ve hired a local HVAC company to help you with those tasks, you’ve had to come to the decision as to whether to repair or replace that heating and air system.

While repairing your system is generally less expensive than installing an entirely new system, paying for constant repair work on your system over time could easily add up to what you would be paying for a new system.

Here are some key indicators and things to look out for — especially system age — to understand if it’s the right time for a system replacement or you should simply keep repairing.

For Younger Systems (Less Than 12-14 Years Old)

Generally speaking, for a system that is 10 years or older, if it costs you more than $500 to keep it running, then replace it if you have the means to. The reason being is because at that age, you will never recoup your investment into that repair and your HVAC system runs into a money pit.

The only other case where a younger system might need to be replaced is if you are unhappy with its performance. This can occur if your system is sized incorrectly or was poorly installed.

For Older Systems (More Than 12-14 Years Old)

Older systems, however well they are currently working, are at a higher risk for untimely major breakdowns. These can often occur at the worst times as well — during the heat of the summer or the cold of the winter — so replacement is usually the best option.

To go along with this, older system are generally much more expensive to repair than younger systems, and repairs won’t necessarily extend the lifespan of your system.

If You Have High Electricity Bills…

While many factors go into your systems’ efficiency & energy use, system age can be a major culprit as to why your system is driving up your electricity use.

Most older systems don’t have the newer, advanced engineering that most modern systems — like the Trane XV20i Variable Speed system — have in place to keep energy use down over the extreme temperature seasons.

While it’s not a perfect science as to know when you should replace or repair your HVAC system, looking out for the items mentioned above should help you decide.
