Is It Time to Replace Your Air Conditioner? Top Signs for Homeowners in Los Angeles & Orange County

Is your AC struggling to keep up with the heat? Discover the top signs it’s time to replace your air conditioner in Los Angeles & Orange County.

If you’ve lived through even one summer in Los Angeles or Orange County, you know how crucial a reliable air conditioning system is. But AC units don’t last forever. If yours has been acting up, running less efficiently, or just feels outdated, it might be time to consider a replacement.

At Smartchoice Service, we help homeowners make confident, informed decisions when it comes to AC installation and upgrades. Here are the most common signs it may be time to say goodbye to your old system.

Your AC Is Over 10–15 Years Old

Most air conditioners have a lifespan of 10 to 15 years—if well-maintained. After that, even with repairs, they tend to lose efficiency and cost more to operate.

Energy Bills Are Going Up (Without Changing Usage)

If your energy bills are climbing even though you’re using your AC the same way, your system may be working harder to cool the home—likely due to aging components, low efficiency, or refrigerant issues.

Repairs Are Becoming Too Frequent

An occasional fix is expected, but if you’re calling for AC repair every season, it’s worth asking if the money spent on repairs would be better invested in a new, energy-efficient system.

Uneven Cooling or Poor Airflow

If certain rooms are always hotter than others, or your system struggles to push air evenly through the vents, there could be issues with the blower, ductwork—or it could be the AC unit itself is no longer performing at full capacity.

Your AC Uses R-22 Refrigerant (Freon)

If your unit is older and still runs on R-22 refrigerant, it’s definitely time to replace it. R-22 has been phased out in the U.S., making it expensive and difficult to source for repairs.

Strange Sounds or Odors

Grinding, banging, musty smells, or burning odors aren’t normal. These signs can point to serious issues like electrical faults, motor wear, or mold inside the unit—all reasons to consider a new system.

You’re Planning a Remodel or Adding Square Footage

If you’re remodeling or adding rooms to your home, your current AC may no longer be the right size or capacity. A professional installation ensures your whole home stays cool and efficient.

Why Replacing an Old AC Is a Smart Investment

Upgrading to a new AC system means better energy efficiency, quieter operation, improved comfort, and lower monthly utility costs. Many of today’s models also qualify for rebates and are eco-friendly, which is a big plus in California.
