When To Consider AC Replacement Instead of Repair

Air conditioning systems typically last around 10 to 15 years, so if your system is nearing the end of its lifespan, it’s best to replace rather than repair it. This is especially true if your system breaks down frequently or if the cost of repairs is too high.

If your AC requires only minor repairs or regular maintenance, choosing repairs rather than a replacement is more cost-effective. However, if your AC needs significant repairs, such as a compressor replacement or refrigerant leak repair, these can add up to the cost of a new unit.

Another important consideration is energy efficiency. Newer ACs are often more energy-efficient than older models, which can significantly lower energy bills over time. If your system is older and you notice increased energy costs, replacing it could save you money in the long run.

Let Donley A/C & Plumbing help you decide the best next steps for you and your air conditioner. Contact us at 602-787-3956 today.

How Often Should You Replace Your AC?

Air conditioners don’t always age at the same pace, but most systems will last the most common lifespan of 10 to 15 years.

After 10 years, your system will likely fall short on performance compared to a newer unit, just on technology and sustained wear and tear, with each additional year leading to lower efficiency, more frequent repairs, and worse performance.

You’ll substantially delay the need to replace your air conditioner if you take care of minor repairs promptly, keep up with annual maintenance, and replace your air filters often. Your system will also last longer if it’s properly installed and well-matched to your cooling needs.

Systems that are too small or too big will usually fail earlier, and even minor errors in installation could shave years off a system’s service life.

Common AC Parts To Need Repair or Replacement

There are many components to an air conditioner, and failure in any of them can lead to problems with performance or efficiency and even shut your system down completely. You’ll frequently see trouble with the electrical components of an air conditioner, especially if you haven’t kept up with annual maintenance.

Mechanical parts also fail frequently, including the belts, blowers, and motors that compress heat and move air through your system. Because these parts constantly move, wear and tear inevitably takes its toll. Routine maintenance to clean and replace them can reduce the risk of them causing lost efficiency or unexpected breakdowns.

Of course, some parts need frequent replacement no matter what, but usually as part of regular maintenance: replacing filters, worn-down bearings, and belts, recharging refrigerant, replacing clogged condensate lines, and more.

The Importance of Professional AC Installation

Hiring a professional AC installer is always better than installing an air conditioning system yourself. Professional installers have the knowledge, experience, and tools to install the system correctly and safely. Attempting to install an AC yourself can be dangerous and may damage the system, your home, or yourself.

HVAC technicians like those at Donley A/C & Plumbing ensure the unit is properly sized and installed for your home and cooling needs. We can also advise you on the most efficient and cost-effective systems for your home and offer ongoing maintenance and support to keep it running smoothly.

Hiring an HVAC pro ensures your system’s installation is safe, efficient, and of the highest quality.

Frequently Asked Questions

How long does an AC replacement typically take?

The duration can vary depending on the installation’s complexity and the system’s size. However, technicians usually finish a basic installation in one to two days.

Do I need to replace my ductwork when I replace my AC system?

It depends on the condition of your existing ductwork. If your ductwork is in good condition and adequately sized for the new system, you may not need to replace it. However, if your ductwork is damaged, leaking, or improperly sized, it may need to be replaced to ensure the new system functions properly and efficiently.

An experienced HVAC technician can assess the condition of your ductwork and provide recommendations for replacement if necessary.
