When to Repair vs Replace your Lexington AC Unit

A working air conditioner is essential when you live in Columbia, SC, or nearby in Lexington, Chapin, Irmo, or West Columbia. But no matter how well your AC has performed over the years, there comes a time when it starts acting up. At that point, you’re left with a decision: should you fix the problem, or is it time to replace your HVAC system altogether?

It’s not always an easy call. The right choice depends on your system’s age, how much it’s costing you, and how well it keeps your home comfortable. Here’s what to think about before making the call.

Key Factors to Consider

Age of the AC Unit

Most air conditioners last around 10 to 15 years. If yours is still fairly new and you’ve kept up with regular AC maintenance, repair might be all it needs. But once it starts pushing the upper end of that range, repairs can become more frequent and expensive. If your unit is past its prime, an AC replacement could save you time and money over the long haul.

Cost of Repair vs Replacement

A helpful rule of thumb is the $5,000 rule. Multiply the cost of the repair by the age of your AC. If that number is more than $5,000, it’s usually smarter to invest in a new system. For example, if a repair costs $600 and your unit is 10 years old, that adds up to $6,000. That’s a strong sign that it may be time to replace your HVAC system.

Home Comfort and Energy Use

If your AC isn’t keeping your home evenly cool or struggles to handle the Columbia summer heat, that’s a problem. Older units tend to lose efficiency, which can lead to hot spots, poor airflow, or high utility bills. A newer system may cool your home faster and cost less to run each month.

Warranty and Safety

If your unit is still under warranty, you could be covered for most AC repairs. But if that coverage has expired, you’re on the hook for everything. And it’s not just about money. Older systems can sometimes pose safety risks or affect your home’s air quality, especially if they haven’t been serviced for a while.

How Long You’re Planning to Stay

If you plan on moving in a year or two, a repair may be the simpler choice. But if this is your long-term home, replacing your HVAC system now could give you greater comfort, fewer headaches, and better energy savings down the road.

Signs Your Air Conditioning Needs Repair or Replacement

Not every AC issue means you need a full replacement. In many cases, a good technician can handle the problem quickly with a standard HVAC repair. But other times, the signs point toward a bigger issue that might require a full system upgrade.

Here are some red flags to watch for:

• Uneven cooling throughout the house
• Strange noises like banging, rattling, or buzzing
• AC turning on and off too often
• Warm air blowing out of the vents
• Water pooling near the unit
• High humidity indoors, even with AC running
• Utility bills that keep climbing
• Needing emergency AC service more than once in a season

If one or two of these sound familiar and your unit is under 10 years old, repair is likely the way to go. But if you’ve noticed several of these problems at once, or if they keep coming back, it may be time to replace the air conditioner entirely.
