When to Replace Your AC in Oregon


Posted On April 28, 2026

On a hot Oregon day, a sudden grinding noise or lack of airflow can be a sign of an impending AC failure. As cooling systems age, they require more repairs and become less energy efficient. By working with Priority One Heating & Air Conditioning, Eugene and Springfield homeowners can determine when to replace an AC and when basic repairs will do the trick.

How Long Do Air Conditioners Last?

So, how long do AC units last in Springfield and Eugene? An average air conditioning system will last about 10 to 15 years. While consistent maintenance can extend the lifespan of your unit, its performance will gradually decline.

There are a few factors that impact how long your air conditioner will likely last.

  • Maintenance: Performing routine maintenance and scheduling timely AC repairs can extend the lifespan of your unit, boost its performance, and reduce your energy costs.
  • Usage: If the unit is used more intensively, it will experience more wear and need to be replaced earlier.
  • Eugene’s Climate: The rising number of days with extreme heat and wildfire smoke can take its toll on heating, ventilation, and air conditioning (HVAC) systems. While routine maintenance can defray some of the damage, our climate can still have a negative impact on how long your AC lasts.

8 Signs It’s Time To Replace Your AC

By paying attention to signs that you need a new air conditioner, you can ensure your Springfield home is cool and comfortable all summer long.

1. Your AC Is 10 to 15 Years Old or Older

Once your AC is 10 to 15 years old or older, the chances of it failing increase significantly. Additionally, your energy efficiency and performance will continue to decline as the unit ages.

2. Frequent Repairs Are Adding Up

If you have to keep performing repairs on your AC, it’s likely time for a replacement. When an AC needs constant repairs, it has reached the end of its lifespan.

3. Rising Energy Bills

A sudden surge in energy costs may mean your HVAC system is struggling, especially if you haven’t changed any of your usage habits.

4. Poor Cooling or Uneven Temperatures

Weak performance is a sign that something is wrong with your AC unit. It’s also a good idea to get your ductwork inspected because damaged or leaky ducts can cause airflow issues and uneven temperatures.

5. AC Uses R-22 Refrigerant (Freon)

Because of the environmental risks involved, R-22 refrigerant is in the process of gradually being phased out. Currently, it cannot be produced or imported in the United States. The only exception is for servicing units that already use it.

While existing ACs can still use Freon, the costs will gradually increase. Because of this, it’s a good idea to replace your AC if you notice other symptoms on this list.

6. Strange Noises or Odors

Your AC may click when it first starts up and hum gently while it is on, but it should not produce consistent clicking, banging, squealing, hissing, or screeching sounds. Any weird smells or sounds should be inspected by a professional HVAC technician right away. 

7. System Runs Constantly Without Cooling Properly

Another indication of when to replace your AC is poor cooling performance. If your unit runs for extended periods and your home still feels warm, it’s time to consider a replacement.

8. Excess Humidity Indoors

Your air conditioner is supposed to pull excess humidity out of the air. If your home feels humid, it means that something is wrong with your AC.

Repair vs. Replace: How To Decide

To help you decide when to replace your AC, you can try using a basic rule of thumb known as the $5,000 rule. You multiply the age of your AC by the cost of potential repairs. If the result is more than $5,000, you should replace your air conditioner. Over the long term, you’ll end up spending more on repairs than you would on a new system.

While the $5,000 rule is a good framework for thinking about the decision, other factors matter as well. For example, someone who is about to sell their house might want to make a simple repair instead of investing in a long-term solution.

If you plan on living in your house for the next few years, a complete air conditioner replacement can save you money in the long run. While it might cost more upfront, you’ll end up spending less on repairs and utility costs over time.

Benefits of Replacing Your AC

By getting an AC replacement in Eugene, OR, you can enjoy a few important benefits.

  • Improved Energy Efficiency: The Seasonal Energy Efficiency Ratio (SEER2) represents an AC’s cooling output over a typical cooling season. Over the years, ACs have become more efficient. By upgrading to a higher SEER2, you can maximize your HVAC system’s energy efficiency.
  • Lower Monthly Utility Bills: Energy-efficiency improvements from a higher SEER2 directly lead to lower utility bills, which can help defray the cost of a new AC.
  • Better Indoor Comfort: A new AC will have the right capacity for your home’s occupants, square footage, and personal temperature preferences. Through a simple upgrade, your family can enjoy a more comfortable, energy-efficient home throughout the summer.
  • Smart Thermostat Compatibility: Smart thermostats can be programmed with temperature schedules for different times of the day. They can automatically adjust based on user preferences as well as fluctuating humidity levels in your home. As a result, upgrading to a smart thermostat can save you a significant amount on your energy costs. For example, an ENERGY STAR smart thermostat saves an average of 8% a year on heating and cooling costs.
  • Environmental Benefits: By lowering your energy costs, you can reduce your impact on the environment. Switching from R-22 to a safer refrigerant type is also an eco-friendly choice.
  • Peace of Mind: One of the most important reasons to replace your air conditioner is for your peace of mind. When the temperature level starts to rise, you don’t want to worry about your AC breaking down. A new unit can give your family greater peace of mind and a more consistent level of comfort.

Cost of AC Replacement in Eugene, OR

When deciding whether to repair or replace an AC in Eugene, it helps to look at prices. The prices can vary based on the size of your home, the system type, and any ductwork installation requirements.

As you consider whether to replace an air conditioner and the cost in Oregon, it’s also important to look at rebates and financing options. The Energy Trust of Oregon offers up to $3,000 in cooling incentives for ductless mini-splits and heat pumps. Plus, utility providers like the Eugene Water & Electric Board offer incentives for programmable thermostats and heat pumps.

At Priority One Heating & Cooling, we make affording AC replacements and repairs as easy as possible. Through our financing partner, you can access the best HVAC financing options for all your needs. Once approved, you can get your project funded in just one to three days.

Choosing the Right AC System for Your Home

Deciding on a new cooling system is a major decision. As a homeowner, you can choose between heat pumps, ductless mini-splits, and central air conditioners.

Ductwork and Whole-Home Cooling Requirements

Central ACs and heat pumps are good options if you already have existing ductwork and want a whole-home solution. Meanwhile, ductless mini-splits are an energy-efficient way to cool specific zones, such as a bedroom or a home office.

Rebates, Incentives, and Tax Credits

Heat pumps also offer a number of other benefits when it comes to heating and incentives. While heat pumps can heat and cool your home, central ACs are only able to cool it. Additionally, heat pumps are eligible for many incentives and rebates from state governments, municipalities, and utility providers. The federal Energy Efficient Home Improvement Credit will provide a 30% credit of up to $2,000 for installing a heat pump.

Sizing Needs

No matter what unit type you choose, you need to get the right sizing. Through our professional load calculation, you can find out the correct size for your home’s square footage, the number of occupants, layout, the number of windows, insulation, and climate.

When Is the Best Time To Replace Your AC?

We generally recommend getting your AC replaced during the spring and fall instead of during the peak summer season. Planned upgrades are easier to schedule, more affordable, and less stressful than getting an emergency replacement during a summertime heat wave. Plus, there are often off-season deals that can lower the cost of your planned AC replacement.

FAQs

How often should you replace your AC?

You should generally start considering a replacement once your AC is 10 years old. While well-maintained units can last up to 20 years, they can lose efficiency over time and require more frequent repairs.

Is it worth replacing a 15-year-old AC?

It depends on the cost of repairs and the unit’s current energy efficiency. ACs start to lose their efficiency after the 10-year mark, so it’s a good idea to consider replacing a 15-year-old AC. This is especially true if your unit requires frequent repairs or you’ve noticed a sudden spike in your energy bills.

How much does a new AC cost in Eugene, OR?

The cost of a new air conditioner in Eugene, OR, varies based on several key factors, including the size of the system, your home’s layout, energy-efficiency requirements, and whether ductwork installation or repairs are needed. Because every home and project is different, the total cost can vary significantly. For the most accurate estimate, a professional assessment is recommended.

Should I repair or replace my air conditioner?

It depends. If the cost of repairs multiplied by the age of the unit is more than $5,000, it’s generally better to replace the AC. You should also consider the unit’s history of repairs, energy efficiency, and whether you plan on selling your home in the near future. 

What is the most energy-efficient AC option?

When it comes to cooling your home, ductless mini-splits and heat pumps are the most energy-efficient option. By switching to heat pumps, the average American homeowner can save $300 per year on their energy costs.
