How to Know When it's Time to Replace a Residential Air Conditioner?

Updated: 3 days ago

If you're a homeowner with an air conditioner, you know that your AC unit is a crucial part of your home. It keeps you and your family cool and comfortable during the hot summer months. However, air conditioners, like all appliances, eventually reach the end of their lifespan. If you're wondering when it's time to replace your residential air conditioner, this quick blog will help.

Knowing your air conditioning unit and keeping it maintained

Age of the Unit

The first thing to consider is the age of your air conditioner. Most air conditioners last between 10-15 years. If your unit is older than that, it may be time to replace it. Even if your AC seems to be functioning well, older units tend to be less energy-efficient than newer models. Newer air conditioners have improved technology that can save you money on your energy bills.

Energy Efficiency

Speaking of energy efficiency, it's important to consider how efficient your current air conditioner is. If your unit has a low SEER rating (Seasonal Energy Efficiency Ratio), it may be costing you more money than it should. A higher SEER rating means that your AC is more energy-efficient, which translates to lower energy bills. Upgrading to a newer, more efficient air conditioner can save you money in the long run.

Frequent Repairs

If you find yourself calling for AC repairs frequently, it may be a sign that your unit is reaching the end of its lifespan. As air conditioners age, they tend to require more repairs. At a certain point, it becomes more cost-effective to replace your unit than to continue paying for repairs. A good rule of thumb is that if your repair costs are more than half the cost of a new unit, it's time to replace it.

Lack of Cooling

If your air conditioner is no longer keeping your home as cool as it used to, it may be time to replace it. A lack of cooling can be a sign that your AC is struggling to keep up with the demands of your home. This can be caused by a number of factors, including a clogged air filter, a malfunctioning thermostat, or low refrigerant levels. However, it can also be a sign that your unit is reaching the end of its lifespan.

Strange Noises

If your air conditioner is making strange noises, it's worth investigating. While some noises are normal (like the sound of air moving through your ductwork), others can be a sign of a problem. For example, a banging or clanging noise can indicate a loose or broken part. A hissing noise can be a sign of a refrigerant leak. If you hear any unusual noises coming from your air conditioner, it's best to have a professional inspect it.

Foul Smells

If your air conditioner is emitting a foul odor, it's a sign that something is wrong. A musty odor can be a sign of mold growth, which can be harmful to your health. A burning smell can indicate an electrical problem. If you notice any unusual odors coming from your air conditioner, it's important to have it inspected by a professional.


Replacing your air conditioner is a big investment, but it's an important one. If your unit is more than 10-15 years old, requires frequent repairs, isn't cooling your home properly, or is emitting strange smells or noises, it may be time to replace it. Upgrading to a newer, more efficient air conditioner can save you money on your energy bills and ensure that your home stays cool and comfortable for years to come.
