As your air conditioning system ages, the inevitable question arises: should we repair or replace the old ac unit? The decision of whether to repair or replace the unit is a complicated decision for many homeowners. The most important factor for homeowners is obviously cost.
Today we’ll discuss the issue of repairing or replacing an old AC unit in Arizona, and give you information you can use to help you make the best decision for your family and budget. We’ll consider the age of the unit in question, the nature of the problems the system might have, and do a cost/benefit analysis about this question. We’ll also take a look at how personal finances factor into the issue. In the end, you’ll be able to make a more informed decision about whether repairing or replacing your ac system is best for you and your family .
Should You Repair or Replace An Old AC Unit?
When considering repairing a unit or replacing your old ac unit, you’ll need to carefully consider a few different factors. Here are some of the most important:
The Age Of The Unit
The age of your AC system is the most significant factor in determining whether to repair or replace it. As with any mechanical system, air conditioners have a finite lifespan, and their efficiency tends to decrease over time.
On average, a well-maintained air conditioning system can last between 15 to 20 years. However, this can vary depending on factors such as usage patterns, environmental conditions, and the quality of the installation. As a general rule, if your unit is approaching, or has surpassed, the 15-year mark, a replacement might be a better way to go, as it’s unlikely to go much longer without needing another repair.
If you don’t take care of your unit, it will have a shorter lifespan, often needing replacement around 11 to 12 years in. This is why it’s worth investing in maintenance, since having to replace a system 5 years early will cost you more than maintaining the unit in the first place.
The Extent of The AC Unit's Problems
One of the most important factors when considering whether to repair or replace an AC system is the current state of the system. If the system is in generally good working order, then minor, fairly inexpensive fixes, such as a faulty capacitor or replacing a fan motor can make good economic sense. When major components break on an older system is where things get a little dicey.
Issues with critical parts like the compressor or coil are not only expensive to repair but often indicate that the system is about to kick the bucket altogether. If you have a 20-year-old unit and your compressor or your coil fails, it’s best to just put that money towards a new unit. In the old days, we used to call that “throwing good money after bad.”
Family Financial Considerations
While an AC replacement is sometimes the better long-term solution, you may not have the money on-hand for a full replacement. Repair may be the only option, even if replacing the system is the most rational choice. But, we all know that family finances aren’t always “rational”. You do what needs to be done with the resources you have available.
One consideration you can look at is not just the cost of the replacement itself, but the potential savings over time. For example, newer AC units are typically much more energy-efficient than older models, especially with new R-32 models. The potential energy savings from a new, high-efficiency system can help offset the higher cost of replacement over a few years. According to the U.S. Department of Energy, replacing a 10-year-old air conditioner with a newer, more efficient model could reduce your air conditioning energy costs by 20-40%.
When Should I Repair My Unit?
Opting for repair is often the best choice when your AC unit is relatively young (typically under 10 years old) and the problem’s minor. If your system has been reliable, and the cost of repair is reasonable compared to replacement, fixing the current unit makes sense. For instance, problems like clogged filters, minor refrigerant leaks, or electrical issues are almost always worth repairing.
Consider repair when:
- The unit is still under warranty, covering parts or labor costs.
- You’ve maintained the system regularly, and it’s been performing efficiently.
- The repair cost is less than 30% of the price of a new unit.
- You’re planning to move in the near future.
- The issue is isolated and not indicative of widespread wear and tear.
Remember, a repair can significantly extend the life of your unit, providing several more years of efficient cooling without the substantial investment of a new system.
When Should I Replace My AC Unit?
Replacement becomes the preferred option when your AC unit is showing signs of chronic issues or decreased efficiency. If you find yourself frequently calling for repairs, or if your energy bills have been steadily increasing despite consistent usage, it’s probably time for a new system.
Consider replacement when:
- Your AC is over 15 years old, especially in harsh climates like Arizona’s.
- The cost of repair is more than 50% of the price of a new unit.
- Your system uses R-22 refrigerant, which is increasing difficult to replace due to phaseouts.
- You’re planning major home renovations or an addition that might require a different cooling capacity.
- Your current system is inadequate for your cooling needs, leading to uneven temperatures or humidity issues.
Investing in a new, energy-efficient AC unit can provide long-term savings on energy bills and repair costs. It also offers the opportunity to take advantage of newer technologies, such as smart thermostats and zone control systems, which can further enhance your home’s comfort and efficiency.
Ultimately, the decision to repair or replace your old AC system comes down to what you need, when you need it and the condition of the existing unit. If you just need the unit to hold on a little longer until you move or can afford a replacement, then it’s a good idea to repair it. If, however, your rusted bucket of a unit can’t stop malfunctioning in one way or another, then the thing has probably got to go!
