Most homeowners depend on an air conditioning system to keep temperatures cool and comfortable indoors, especially during the hot months of summer. Using a central air conditioning unit has been the go-to solution to manage unbearable weather. Most air conditioning units can last for at least ten years, provided they undergo regular checkups and maintenance. In time, however, the system will break down and have to be replaced. Is it time to get a new system for your home? Learn how to assess your unit, identify issues, and find the best option as a replacement.

6 Common Causes of Air Conditioner Failure

All mechanical units (their digital components included) can and will fail eventually. Here are the reasons why:

Age

On average, an air conditioner will last for about 17 years if it was bought brand new. An older unit is likely to show signs of age after it reaches the 10-year mark. Once it gets to this stage, it will require more energy to run, which means you will spend more for the same level of comfort. It is also likely that an older unit will require more repairs and replacement of worn or old components.

Frozen Coils

In air conditioning units, coils are responsible for cooling warm air. Over time, dirt, debris, and other particulates may slip inside the unit, preventing warm air from getting to the coils. This results in the failure of the coils to cool the air, causing them to become frozen.

Refrigerant Leak

The refrigerant is a chemical inside the coils that cool the air. Without a refrigerant, air conditioning units simply will not work. One of the reasons why the A/C unit fails to produce cool air is a refrigerant leak. When this cooling element is absent from the system, it will no longer produce cool air.

Overworked Contactors and Capacitors

Contractors and capacitors work to ensure that the A/C motors are running. These components keep the blower and fan motors operational. Electrical power runs through these components, causing them to become overworked and overheated, particularly when they are used constantly, such as during the summer months.

Electrical Problems

In older air conditioning units, wiring could begin to break down or become worn out. This will affect the performance of the circuit breaker. Other than age, an error in the set up may also cause wiring to become problematic.

Defective Thermostat

The thermostat component acts as the temperature gauge, and it also activates the air conditioning unit by turning it on or off. When a thermostat fails and provides false information, the A/C may fail to turn on or off when necessary.

Easy Troubleshooting Tips

Not every issue that an air conditioner shows requires the expertise of an HVAC technician. Some problems are simple enough for you to fix. Here are three basic steps you can do on your own to keep your air conditioner in good shape:

  • Keep the unit clean by wiping surface dirt and dust periodically. You may also have the unit cleaned professionally and inspected annually. Regular checkups will help keep the unit in good working condition longer.
  • Check the fuse and circuit breaker from time to time to determine if there are any potential problems with its electrical components.
  • Get the furnace filters replaced every month or every three months depending on their condition. This will keep the filters clean and working efficiently.
  • If there are other issues that affect your air conditioning unit, do not attempt to fix it on your own. Call an expert technician. We can perform a thorough diagnostics of your unit for free to determine what types of repairs or replacements are needed.

What to Consider When a Replacement is Required

One concern that homeowners have is when to replace the A/C unit. First, Enercare will perform a professional assessment to determine if the unit can still be repaired. However, if repairing the unit will cost more than having it replaced, we may recommend a replacement. Before choosing a unit, consider these factors first before deciding to buy:

Efficiency and Age

If your unit is at least 12 years old, its efficiency level could be very low, which means you may be spending more money using it than you should. You might be able to save more if you purchased a new, energy-efficient unit. The most efficient appliances are given a SEER (Seasonal Energy Efficiency Ratio) rating. Today’s SEER rating is usually set at 13 at the minimum. Some of the most efficient units even have a SEER rating of 25.5. Higher figures mean a higher level of efficiency, which means the appliance is cheaper to use.

Space Changes

If the room had been reconstructed, try to choose the air conditioning unit with the right capacity. If the room is smaller or had been extended, choose the appropriately-sized system. An air conditioner with a smaller capacity placed in a large room, for example, will be less effective in keeping the area cool. To ensure that you buy the correct unit, ask a contractor to perform a load analysis.

Cost of Replacing Your Air Conditioner

The biggest consideration for most homeowners when it comes to AC unit replacement is cost. Fortunately, there are rebates that will help you save money. The amount of utility and government rebates available to you will depend on which unit you choose to install. We offer high-quality options in an installation that often includes a rebate. Our highly trained technicians will assess your unit to determine which type of unit is best for your needs. We will discuss the options you have, including brand, model, capacity, and rebates. We will help you work out a solution that meets your cooling needs and your budget.
