Air Conditioner Lifespan: When is it Time to Pull the Plug?

Buying a new air conditioner is a big investment. It’s important to understand how long your air conditioner’s lifespan really is and when it’s time to replace so that you can budget appropriately when it’s time to finally pull the plug on your old unit. Below, we’ll discuss how long a typical AC unit lasts, when you know it’s time to replace, and what you can do to prolong the life of your air conditioner.

How long will my AC last?

The average lifespan of a central air conditioning unit is 15 to 20 years. However, if you want your air conditioner to perform optimally during this time, it’s important that you take care of your system with adequate maintenance.

Here are just a few of the preventative HVAC maintenance tasks that you should routinely complete to prolong the life of your AC equipment:

  • Replace your air filter every 1-3 months.
  • Get a seasonal HVAC tune-up, preferably before winter and summer.
  • Keep your air conditioning equipment clean and well lubricated.
  • Get your HVAC equipment inspected for repair needs.
  • Repair or replace any damaged parts as soon as possible.

Many homeowners find that an HVAC maintenance plan is the best way to ensure that their HVAC system gets the proper maintenance it needs throughout the year. With an HVAC maintenance agreement, you get the benefit of having an experienced and licensed HVAC technician inspect, clean, and maintain your system for optimal performance.

When is it time to replace my air conditioner?

There is no one right answer for when it’s time to replace your air conditioner. Most homeowners decide to replace their AC when the cost of repairs outweighs the cost of a new unit. While others choose to purchase and install a new air conditioner when their old unit is no longer keeping their home comfortable.

Here are a few factors you will want to consider when deciding whether it’s time to replace your air conditioner:

  • Age – If you have an older air conditioner, you may find that it’s not as efficient as a new system. Newer systems tend to use 20 to 40% less energy that units that were sold just 10 years ago. If efficiency and saving money on your electric bill is important to you, you may want to consider purchasing a newer, more energy efficient unit.
  • Repair Needs – Is your current AC always breaking down? Whether it’s due to age, over use, or some other cause, if your air conditioner needs frequent repairs, it may be time to replace it. Consider how much you are spending on repair costs and what a new system would cost to determine which is more cost effective.
  • Home Comfort – Your air conditioner’s most important job is keeping your family comfortable and creating a healthy living space. If you find that your AC is just not meeting your home comfort needs, it may be time to look for a new unit. Consider what features are most important to you before shopping for a new HVAC system.

Who Needs Air Duct Cleaning, When and Why?

Your air duct system helps keep your living space comfortable by distributing conditioned air into every room of your home. The air inside your home contains tiny particles like dust, dirt, pollen, pet dander, and other debris that can build up inside your air ducts over time. If this debris builds up too much, it can start to restrict air flow in your living space. Sometimes it can even re-circulate the particles throughout your home, impacting indoor air quality.

When performed by HVAC professionals, air duct cleaning services help eliminate this buildup of debris in your duct system. But duct cleaning may not be necessary for every home. Read on to find out what air duct cleaning is and if you need it in your home.

When do air ducts need to be cleaned?

Frequent air duct cleaning is not a necessity for most homes. However, there are a few serious issues that may indicate your air ducts need to be cleaned by HVAC professionals:

  1. There is visible mold growth in your ducts.

If you notice mold growth in your air ducts or on other parts of your HVAC system, it’s time to get it checked out by a professional. An HVAC technician will be able to inspect your system, determine if you have mold growth, and suggest the best next steps for cleaning your air ducts. Remember, if you don’t get rid of the conditions that caused the mold, it will come back! So if you find mold growth in your ducts, you will still need to find the source of the issue and remedy this as well.

  1. Your ducts are infested with rodents or insects.

If you find that vermin have started to camp out in your air ducts, then it’s time for a cleaning. Not only can rodents and insects in your ducts impact your indoor air quality, but they can also cause damage to your air duct system that can become costly to fix.

  1. Your HVAC system has become less efficient.

Research shows that cleaning your air ducts and other HVAC system components can help improve the efficiency of your system. Similarly, it can help you prolong the life of your HVAC equipment.

If you notice that your HVAC system has become less efficient, it may be time for duct cleaning. However, other issues may also be causing the decrease in efficiency so make sure that you consult with your HVAC technician first.

  1. Debris is re-circulating through your home.

A little dust or dirt in your air duct system is normal. However, if you start to notice that debris or particles are being released into your home through your supply registers, then it’s definitely time for an air duct cleaning. At this point, the debris has starting to impact your indoor air quality and can have consequences for your health.

  1. Your system won’t maintain ideal temperature or airflow.

If your HVAC system is struggling to keep your home comfortable or you notice a change in airflow, dirty air ducts may be to blame. When debris accumulates in the ductwork, it can restrict the airflow throughout your home, making it harder for your HVAC system to maintain home comfort.

It’s important to note that these issues could also be the result of damage to your HVAC system. You will need to get an HVAC technician to inspect your ductwork and diagnose your system needs.

How to Save Energy in Big, Old Commercial Buildings

Did you know that 20% of all the energy we use in the U.S. powers commercial buildings? This can be anything from office buildings to schools to government offices. With this much of our energy use going to commercial buildings, it’s important that we work to keep these buildings as energy efficient as possible.

However, according to, the average commercial building wastes 30% of the energy it consumes. With this in mind, there are a variety of ways that commercial building owners can work to improve energy efficiency measures to save more energy and money over time.

5 Commercial Building Energy-Saving Tips

Unfortunately, the same energy-saving tips for homeowners are not necessarily effective for older commercial buildings. That’s why we’ve put together a list of simple tips that you can use to improve energy efficiency in your commercial building.

  1. Turn off lights when not in use.

When you are not using lights or daytime light is sufficient, be sure to turn off the lights within the building. This includes during the night time when no one is working in the office. Turning off lights when not in use can reduce lighting expenses by up to 40%.

  1. Monitor computer power usage.

Computers use a lot of energy over time, so it’s important to be smart about how you manage computer use. Use power management functions to ensure that computers and computer monitors go to sleep when not in use. You should also activate sleep settings on other office equipment such as printers, copiers, and scanners.

  1. Use smart power strips.

Plug any electronics into smart power strips that allow you to designate which electronics are always on and which are switched off when not in use. Using a device like this can help you save energy by turning off the power supply to the devices that do not need to be on continuously.

  1. Use programmable thermostat to adjust temperatures at night.

To save energy when the building is not in use, you can use a programmable thermostat to adjust the temperatures at night. This will ensure that you are using less energy when the building is unoccupied, while still maintaining comfortable temperatures during the day when the building gets the most traffic. Also, remember to adjust thermostats during seasonal temperature changes to save energy.

  1. Repair damaged and missing insulation.

Just as insulation plays an important role in home energy efficiency, it’s also a vital part of maintaining efficiency in commercial buildings. Repair any damaged insulation and replace missing insulation with the proper insulation for your commercial building. Proper insulation helps ensure that hot and cool air are not escaping the building.

Save Energy with Routine Commercial HVAC Maintenance

In addition to the tips above, it’s important that you get ongoing commercial HVAC maintenance for your building’s heating and cooling systems. This goes beyond just changing the air filter regularly. You also need to get annual tune-ups and maintenance services to ensure that your system is working properly. Wear and tear on your HVAC system’s parts can make your commercial heating and cooling equipment work harder than it needs to. This not only results in increased energy usage, but can also cause lasting damage to your system.
