"Air Tech was great. I would HIGHLY recommend. I initially had 2 other companies besides Air Tech come out for a replacement estimate. Price wise Air Tech was right in the middle but were doing a lot more than the other 2 quotes I got. For example they were changing the copper refrigeration lines, which the other 2 weren’t going to do. When I called the other 2 companies to add the lines in there was going to be an additional $1500-$2000 charge. I’m very pleased with this the work that was done by Air Tech"

"Chris was able to fix our ac unit, where my old account guy said we NEEDED to replace it!!! Plus Chris is very personable and I believe he is very honest and forthcoming as he could have sold us a new system, but found us a much cheaper option!!"

FAQs for swamp cooler service or repair projects in Diamond Bar, CA

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.
