3 Things That Cause A/C Failure

Electrical problems, inadequate oil lubricant and blocked suction lines are all things that can cause your AC unit to fail. While these are important to think about, the real failure comes from lack of preventative care for your unit. We have identified the three main things that, on a larger level, cause A/C failure.

Regular Maintenance

  1. The biggest thing we stress to all of our clients is regular maintenance. Our production manager Andy Gibson said it best when he said “Regular maintenance really goes a long way. Not maintaining your AC unit is a lot like buying a new car and never changing the oil”. We recommend cleaning and servicing your unit once a year. The ideal time to clean is spring, just before the cooling season starts. Regular changes to filters not only keeps the air in your home cleaner, it helps your unit run more efficiently, which saves you money on monthly bills and helps your unit last longer.


  1. While maintenance is crucial for keeping your unit clean, there are a few things too look out for between scheduled service. In the spring cottonwood and pollen can do a lot of damage in blocking up your air filter. If you can’t see the coils, it’s time to address the problem. Keep an eye on your filters and overall cleanliness of the unit, if it looks dirty or blocked up, it’s time to call in the professionals.

Professional Technicians

  1. Speaking of professionals, one thing that can really do damage on your unit is an inexperienced ‘technician’. Your air conditioner is an investment and worth paying a professional to fix and maintain. Improper maintenance and a quick fix can do long term damage to your unit. Don’t risk damaging your unit with inexperienced service, trust professional technicians to protect your investment and keep your unit running efficiently longer.
