Common Causes of AC Problems 

With over four decades of experience, our team of talented technicians has dealt with all types of AC issues. Your air conditioner is a complex system made up of several mechanical components. If your unit is running constantly, cycling too frequently, or showing any other signs of failure, there are several potential causes. 

Some of the most frequent causes of AC issues include: 

  • Clogged air filters
  • Dirty or frozen evaporator coils
  • Faulty thermostats
  • Low refrigerant charge
  • Broken blower motors
  • Blocked condensers
  • Leaky ductwork
  • Improperly sized AC
  • Lack of maintenance

If you’ve recently noticed your AC struggling to keep up with your cooling demands, call our professionals for an expert evaluation. We’ll identify the source of the issue and advise you on the repairs that should be made. Once you approve the work to be done, we’ll get it taken care of quickly and efficiently. You’ll be back to being cool and comfortable in no time!

How to Prevent AC Damage 

Eventually, all AC units will begin to experience problems. However, you can significantly reduce the frequency and cost of repairs with routine maintenance. An air conditioner should be serviced by a professional once a year to maintain optimal operational capabilities. A service technician will perform many tasks, such as changing the air filter, cleaning components, and lubricating parts. Regular maintenance is also useful in detecting minor issues before they become major problems. By investing in a low-cost annual maintenance program, you will end up saving yourself a ton of money on energy bills, repair costs, and premature replacement.

The team at Controlling Systems is trained to repair AC systems that are made by all major manufacturers. As a Ruud Pro Partner, we specialize in repairing Ruud air conditioners.
