Is It Time to Replace Your AC Before Next Summer

If your air conditioner barely made it through last summer or left you sweating through heat waves, it may be time for an AC replacement. Upgrading your air conditioning system before the summer arrives gives you better control, comfort, and energy savings. Learn when you should replace your air conditioner and how the expert team at AC Plus can help.

How To Tell if It’s Time to Replace Your AC

The right time to replace your AC depends on its age, performance, and efficiency. Consider these factors to make an informed decision about your AC replacement.

Unit is Nearing or Past Expected Operating Life

Most air conditioners last between 15 and 20 years with consistent maintenance. As it nears the end of its lifespan, your system’s performance may decline to the point where AC replacement is more practical than repair.

Increasingly Frequent or Costly Repairs

Multiple or costly AC repairs signal that your AC’s components are wearing out and the system is approaching the end of its operating life. For example, compressor failure and damaged coils often come with repair costs that equal or exceed the cost of a new system.

High Energy Bills

Air conditioners lose energy efficiency as they age. Worn components strain your system’s cooling power, so your AC works harder and uses more power to maintain comfortable temperatures. This translates to higher energy consumption and energy bills, even if your daily usage hasn’t changed.

You’ve Remodeled Your Home

If you’ve made significant changes to your home’s layout or square footage, such as converting a basement or garage, building an addition, or remodeling spaces, your current AC may no longer be the correct size. An undersized unit will struggle to cool the additional space, while an oversized unit may be too powerful, overconsume energy, and wear out faster.

Signs Your Air Conditioner Is on Its Last Legs

Even if your air conditioner still turns on, certain symptoms indicate that it’s imminently approaching system failure. Look for these signs that you need a new AC to anticipate potential breakdowns and start planning for a replacement:

  • Loud noises: Grinding, clanking, buzzing, or rattling noises indicate that mechanical issues inside the unit, such as failing motors or a damaged compressor.
  • Strange odors: Burning smells suggest overheating components, while musty odors may come from mold on coils or in ductwork, often due to poor humidity control in aging systems.
  • Rapid or constant cycling: Short cycles point to refrigerant leaks, overheating, or incorrect system sizing. Constant running usually indicates that the system can’t keep up with cooling demands.
  • Poor cooling performance: Hot and cold spots, insufficient cooling, or poor humidity control are common signs of an aging AC.
  • Refrigerant leaks: Hissing sounds, frozen coils, or visible pooling near the AC may point to refrigerant leaks, which cause compressor and overall system damage without attention. Some older ACs also use phased-out refrigerants, such as R-22, and are more challenging and costly to repair.

Why You Shouldn’t Wait Until Summer To Replace Your AC

Planning for your AC replacement offers several advantages and helps avoid the stress of a breakdown during a heat wave.

Avoid Peak Contractor Demand

Summer puts high demand on everyone’s ACs and is the busiest time for AC installation and repair. Replacing your system before the temperature spikes gives you more scheduling flexibility and minimizes interruptions to your cooling.

Give Your Replacement a Comfortable Timeline

Choosing the right air conditioner involves careful consideration of sizing, energy efficiency, and other factors. Replacing your unit early gives you the time to research your options, plan for potential upgrades to ductwork or electrical, and avoid rushing into a purchase if your current system suddenly fails.

Enjoy Better Comfort When it Counts

An underperforming AC might get through spring or early summer but break down once the peak heat of July or August arrives. If your system already shows signs of failure, proactive replacement lowers the risk of emergency breakdowns and interruptions to your comfort.

Get Off-Season Deals

AC manufacturers sometimes offer seasonal discounts or clearance pricing ahead of peak season. These deals can significantly reduce the cost of a new system, providing you with extra savings or room in your budget for extra features.

AC Repair vs. AC Replacement: What’s the Better Investment?

Choosing between AC repair and replacement depends on the age, performance, and type of repair required for your system. In general, AC repair is a better option if the repair is minor and the system is less than 10 years old and in generally good condition.

Replacement may be a better investment when:

  • The system is more than 10 years old.
  • Repairs are frequent or expensive.
  • Energy bills are rising without higher usage.
  • The AC can’t match cooling demands.
  • The system uses outdated components or refrigerants.

Benefits of Installing a New Energy-Efficient AC Unit

Replacing your system with an energy-efficient air conditioner provides several benefits.

Lower Monthly Energy Bills

Modern ACs with high SEER2 ratings come with advanced components that use less energy. Upgrading to an energy-efficient system that’s sized properly for your home reduces energy consumption and lowers your utility bills.

More Consistent Indoor Comfort

New systems provide even airflow and humidity control, maintaining stable and comfortable temperatures and healthier air throughout your home. Advanced components in energy-efficient models also enable quieter operation, minimizing background noise.

Eligibility for Rebates and Tax Credits

Energy-efficient systems may qualify for state energy rebates and local utility incentives. These programs offset the upfront cost of a new AC system.
