How to know when it's time to replace your air conditioning unit

It can be hard to know when it's time to replace your air conditioning unit. Sometimes, the signs are obvious – like when your energy bill starts to skyrocket in the summertime. But other times, it's not so clear. If your AC is on the fritz and you're not sure whether or not to call a technician, here are four questions to ask yourself.

You can't avoid the need to replace your air conditioning system forever. Usually, manufacturers' warranties run from five to ten years, depending on certain factors such as climate and location. If you live in a temperate area with mild seasons, you may be able to get away with replacing your unit every eight or nine years instead of after seven. Some parts, such as the outdoor condenser fan motor, don't last more than a few years. Other parts of an air conditioning unit survive longer. The compressor can last up to twelve years or more if it's run frequently enough and you keep the evaporator coil clean.

The cost of purchasing and installing an air conditioning system averages $6,500. The actual price varies based on the size of your house, whether you're installing central air, what features you want in your system, and several other factors. No matter how old your air conditioner is, that number should give you a good idea of what to expect when it's time for replacement. If you haven't already noticed problems, you will soon.

Over time, any system accumulates hard water mineral deposits (scale), clogs in the drainage and condensation systems, and mold and mildew growths. If you have pets, their fur can even get trapped inside your evaporator coils. That debris contributes to inefficient operation of your air conditioner, so it's time for replacement if you notice it.

The most common problems to look out for are:

- Low cooling capacity

- Frequent system shut offs and restarts

- High electricity bills despite the AC being off sometimes as long as an hour at a time

If your unit is still under warranty, check with your manufacturer. If you bought it used, these may be signs that the warranty doesn't apply and you should replace your air conditioner.

Regular maintenance of your air conditioner by a professional. Most AC companies offer at least a semi-annual maintenance program, and some even offer programs that cover all seasons. You may be able to use your manufacturer's warranty for repairs if you have a regularly scheduled maintenance program.

It's also time to consider replacing your air conditioner if you notice an increase in noise. The most common reasons for excess noise are:

- Worn out fan blades

- Worn out bearings 

- Worn out motor couplings

If your system is still under warranty, contact the company that sold you your unit and ask about how to replace worn parts. If not, shop around for a replacement. Replacements don't have warranties unless you purchase an extended warranty from the retailer who sells you the new air conditioner or one of the major manufacturers.

If you live in a harsh climate, you may need to replace your air conditioning system every five years instead of every seven or eight. If you live in a milder area and keep up with the maintenance, it may last ten years or more. As soon as you notice any problems, get them dealt with right away before they get worse.

Conclusion:  You’ve been running your air conditioning unit for a while and it just doesn't seem to be cutting the mustard anymore. It sounds like a truck is passing by when you turn on the AC, or perhaps you have an office full of people sweating in front of their computers during summer months.
