One of the most common questions asked of HVAC technicians is, “How often should I replace my central air conditioner system?” The answer truly varies based on many different factors, but there are some general consistencies and guidelines to follow. Here’s what you need to know.

The Average Lifespan of an Air Conditioner

Most of the air conditioners built today will last somewhere between 15 and 20 years before they’ll need to be replaced. Even if these systems are built with the best and highest-quality parts, something will come along in the next two decades that will render it inefficient. For this reason, most HVAC technicians will recommend replacing any HVAC system that is 15 to 20 years old with a newer, more efficient model. Most of the time, doing so will help you save money in the long run, even if the initial investment is a little more than you’d planned for.

Repair or Replace?

Even if the average air conditioner lasts 20 years, the truth is that this is an average. Some may fail after just 10 years, and others may last for 30 without so much as a single repair if they’re well-maintained. If your central air unit is getting up there in age, and you’re paying for at least one major repair every year, then it’s probably time to think about investing in a new system. The money you’re spending on repairs will add up, as will the inefficiency of a system that isn’t performing optimally.

Making the Decision

If a technician recommends that you replace your HVAC system with a newer model, it may be worth it to obtain a second opinion, if only for your peace of mind. While systems that are 10 years old don’t always need to be replaced, there are some circumstances in which it may be the best choice. If the system wasn’t well maintained during its lifespan, or if it is especially inefficient, replacement may just save you money, and very quickly, at that. Your technician should discuss all your options with you and help you make the right choice for both your budget and your comfort needs.

Finding a Trusted HVAC Company

Part of making the choice to repair or replace a central air conditioner system involves getting information from a company you can trust. This can be tough, especially when you have so many companies from which to choose locally. A trusted reputation and great customer service are the two main qualities you’ll need to look for. After all, if previous clients and customers are happy, then there’s a good chance you’ll be happy, as well.

A central air conditioner system usually lasts 15 to 20 years before it needs to be replaced, but in some cases, it may need to be replaced sooner. Just because it’s still running doesn’t mean you should continue to use it – inefficiency can be a major expense by itself.

A central air conditioning system is an expensive investment, but most systems aren’t meant to last for much more than ten years. Ideally, it should be energy-efficient, while maintaining optimal comfort in every part of the home. Your system should be able to reduce the humidity level that contributes to the discomfort of summer heat, while lowering the temperature enough to let people sleep well or enjoy their activities when they’re awake.

Even with regular maintenance, you may reach a point where your air conditioning system isn’t functioning well enough to keep your home comfortable during the hottest part of the summer. Here are a few signs that may indicate that it’s time to replace your central air conditioning system with a new air conditioning unit.

Central air conditioner lifespan
The average lifespan of an air conditioning system is 10-15 years. Central air conditioner lifespan is one of the more important factors to consider when planning to invest in a replacement unit. If your unit is close to ten years old or older, you may want to consider replacing it instead of repairing it. Heating and cooling costs account for roughly 44% of your utility costs. If you’re paying more than the average for your area, your air conditioning system may not be working effectively.
Older air conditioning units also use R22, a refrigerant, which is being phased out over the next few years out to meet environmental protection regulations. Replacing this refrigerant in older air conditioning units to one that complies with these regulations is expensive and since R22 is being discontinued, it's becoming more difficult to source. New air conditioning units are all manufactured to comply with these regulations and are designed to be much more energy-efficient. Using the correct refrigerant, they are also far more eco-friendly because they release fewer carbon emissions. By installing a new air conditioning system you will also notice a significant improvement in your home’s indoor air quality. A newer air conditioning system will also increase the resale value of your home.

Excessive noise and dust
The constant presence of dust in your home – even after cleaning, is a good indication that there are leaks in the ductwork. Those leaks will compromise the efficiency of your air conditioning system, and that will increase the operating cost. If your air conditioner is excessively noisy, there is a good possibility that your duct system isn’t large enough for the square footage of your home. It’s also possible that you have a problem with the unit’s indoor coil.
Your air conditioning-related expenses are increasing
If your utility bills are going up and there isn’t any change in the way you’re using it, that’s a good indication that your system is no longer as efficient as it should be. Another obvious sign is the amount of money you are paying for air conditioning repairs, and the frequency with which you have to have the system repaired.
Cooling and humidity inconsistencies
Your home’s air conditioner is supposed to remove humidity from the air because excessive humidity makes the space more uncomfortable. When it functions, the unit will maintain consistent temperatures throughout the house. When the cooling portion of your HVAC system isn’t able to do these things, either your equipment is malfunctioning, or there are issues with your ductwork. Think about the cost of repairing these problems, and ask yourself if the central air conditioning repair cost is worthwhile.
These warning signs may be an indication that you should think about replacing your air conditioning system. It’s natural to be concerned about the cost of replacing part of your HVAC unit. It’s an expensive purchase, and a huge investment in your home. Don’t panic at the prospect of having to come up with a lot of money upfront. A new air conditioning unit may wind up eliminating the constant repair costs, and lower your utility bills enough to help you recoup part of your investment. A newer, more energy-efficient air conditioning system will also increase the resale value of your home.
