How Long Do Air Conditioners Last in Louisiana

How long do Air conditioners last in Louisiana is a common question we receive as Morgan City’s trusted AC company. Air Conditioning systems last for varying lengths of time depending on many different factors. You should take into account your current system, where you live, and how well it is maintained. HVAC systems typically last between ten and twenty years.

Your home is cooled with an air conditioner. They usually look like large boxes with fans inside and are situated outside your home.

Most air conditioning units last 15 years or so. Salt exposure can cause units in coastal areas to deteriorate much more quickly. Generally, air conditioners only last between seven and ten years in regions near saltwater.

The compressor of an air conditioner is usually replaced when it fails. A condenser should also be replaced if it shows signs of serious problems, such as leaking or corrosion. Call Southern AC and Heating if you need any AC repairs in the Morgan City, LA area.

How to make your air conditioner last longer

1. Keep All Vents Open

You can trust Southern AC and Heatings experts to know exactly what you want. When a room doesn’t get much use, such as a guest room or storage area, why should you keep the registers open? While it may be tempting to close those registers to save energy, your air conditioner will have to work harder as it tries to cool your entire home.

Make sure that all of the registers in your home are open to allow air to flow freely. This will help your cooling system last as long as possible. Furniture and rugs of a large size can easily impair airflow and make your air conditioner work harder. Open all the interior doors at the same time, too, to improve air circulation.

2. Replace Air Filters Frequently

Simple as they may seem, air filters are some of an air conditioner’s most important parts. They not only keep pet dander, dust, pollen, and other airborne pollutants from entering your home’s air supply, but they also keep them from slowing down your air conditioner.

Make sure that the HVAC filter is changed at least once every three months to keep your home’s air supply and air conditioner as clean as possible. The filter should be replaced every month if it is used heavily, such as during the summer months.

3. Schedule Regular HVAC Maintenance

HVAC maintenance should be a top priority if not scheduled once a year. It is imperative to perform regular HVAC tune-ups in order to keep your air conditioner running efficiently and to identify minor problems before they become major ones. Air conditioner tune-ups can also enable your air conditioner to run more efficiently for longer by ensuring that it is not working harder than it needs to keep you cool.

4. Update Outdoor Landscaping

If you want your cooling system to function at its best, you have to maintain your AC’s outdoor unit regularly. Trim back bushes, trees, and shrubs so there is at least two to three feet between them and the unit.

Additionally, keep the nearby grass short throughout the growing season, and remove fallen leaves and twigs regularly from the unit. Keeping your outdoor unit clean and clear only takes a few minutes every week, but it ensures that nothing blocks the airflow or causes it to work too hard.

Make sure that the HVAC filter is changed at least once every three months to keep your home’s air supply and air conditioner as clean as possible. The filter should be replaced every month if it is used heavily, such as during the summer months.

When To Install A New AC Unit

It doesn’t always make sense to keep repairing an older ac unit when it is beyond repair. Your ac unit should be replaced or repaired when: 

  • It is over 15 years old
  • Repairs are becoming frequent

Older units are not as energy efficient as newer units, so even though you might be able to squeeze a couple more years out of your older unit it might not be the financially best choice. Newer units are extremely energy efficient and cost lost in monthly utilities. So you make be able to extend your older unit but it may actually be costing you more rather than purchasing a new ac. 

If you’re having to call out an ac repair company repeatedly for your ac unit to work correctly you may be spending more on repair bills than what a new unit would cost in the long run. Call us today for a free estimate and inspection on your ac unit. We’ll let you know if we think you should replace or repair. 


What Size AC is Best

There are different sizes of air conditioning units. Your home’s size and cooling needs will determine what size to get. Choosing the wrong size air conditioner will result in hot air in your home, while too large a unit will run short cycles, wasting energy. A professional should be able to determine what size air conditioner you need.
