When Should I Repair or Replace My AC?
Spring is finally here! Many homeowners wonder when should I repair or replace my AC?
Landry Mechanical is here to offer expert advice on when you should consider repairing or replacing your AC.
How Long Do Air Conditioners Last?
According to Carrier, you can expect a good 15 to 20 years of cooling from a new high-efficiency air conditioning system.
However, there are a number of factors that impact how long air conditioners last.
- Climate (Especially High Humidity)
- Air Quality Issues such as pollution or salty sea air
- Regular or Irregular AC Maintenance
- Installation Quality & Proper Sizing
- How Often The System is Used

When Should I Repair My AC?
New Central Air Conditioners can be an expensive investment.
Therefore, if your existing unit isn’t running properly it might be a good idea to consider repairs before replacements.
You Have A Newer Air Conditioner
If you have a newer air conditioner that’s less than five years old, it would be best to repair it. Many Air Conditioners come with a warranty that may cover repair costs.
You Have a Small One-Time Repair Need

When Should I Replace My AC?
When it is no longer feasible to repair your AC it’s time to consider replacing it.
Here are some of the best reasons to replace your AC.
You Want To Lower Your Energy Bill
Older AC systems are not as energy efficient as newer models.
One of the best ways to reduce your energy cost is to replace old AC systems with new more efficient models.
However, this must be balanced with the cost of the new system.
Your Old AC Unit Is Rusty Or Ugly
If your old AC unit has signs of rust, corrosion, or is just ugly it’s time to replace the unit. Repair will not be an option in this case.
Your Air Conditioner is Too Small
Not All AC Units are equally powerful. Some AC systems are great for one room, but are unable to cool an entire house efficiently.
Also, underpowered AC units can raise your energy costs and shorten the unit’s lifespan by running it constantly.
Your AC System is Mismatched
In a central air system you have indoor units and outdoor units.
These components need to be compatible in order to cool your home effectively.
If you have a mismatched AC system, it won’t run smoothly and is far more likely to break down.
