"I'm utterly delighted with this company! I had been with a company for the past 11 years, but their service was going downhill due to selling out to a large Corp (APEX). So Cal Boys came recommended on Angi's list. I AM SO HAPPY I CONTACTED THEM!!! George and his brother Earvin came out yesterday to assess the problem (dirty sock syndrome on the AC) and today they installed a new, Lennox AC for a very reasonable amount (less than half of what I paid for my original system 11 years ago."

"Jesse replaced both units and added two attic fans that keep our house cool during the summer! He was very clean and professional. Jesse explained what work needed to get done.

We highly recommend him. Can’t say enough good things about him and his services."

A well-maintained swamp cooler can last between 10 and 15 years. Its longevity depends on usage frequency, water quality, and proper care. Regular maintenance, like winterization and protective measures, can preserve your system's efficiency and prevent premature breakdowns, ensuring reliable cooling performance over its lifespan. Hiring a professional to take care of any repairs over your swamp cooler’s lifespan will ensure it’s restored to proper functioning and can help it last longer.
You should consider replacing your swamp cooler if it shows signs of severe corrosion, inadequate maintenance, advanced age, restricted airflow, or ongoing leaks. When repair costs and performance inefficiencies make restoration impractical, replacement may be the best option. Evaluating these issues with a professional ensures you choose the most effective solution, preserving comfort and cost efficiency while avoiding further deterioration of the system.
