"Called Aether for a HVAC inspection prior to listing our home for sale. Nico and his team were friendly, professional and did a thorough inspection of our system. They did find a couple tune up issues, his recommended fixes (valve replacement/exhaust repair) were done well and Nico explained how it might affect a home inspection if those weren't resolved. Aether provided great service and I wouldn't hesitate to hire them again."

"The repair was made.  Sean, the service tech was courteous and professional and obviously knew what he was doing. He replaced the circuit board which took less than 1/2 hour and for that I was charged $597.00. Thinking that the circuit board was pricey (Sean, the service tech indicated so), I thought the repair bill of $597 was reasonable.  Only after calling some stores (the next day) and finding out a circuit board cost $125 did I realize I got ripped off. Controlling Systems labor charge for 1/2 hour work amounted to $472. I called the owner/guy in charge to request a refund for part of the labor charge. (I really didn't expect to receive anything) Not only did this person(whose name I wished I remembered, I would state it here) not want to hear my complaint, he hung up on me because he knew he ripped me off. He was rude and didn't want to hear my complaint. He obviously didn't want to hear anything I had to say, only stating that I agreed to the repair charge beforehand. To that he's correct, I did agree to the charge but when I asked Sean what was the cost of the circuit board, he said  $250-300. Now I know parts are marked up when purchased through a company such as CS but I still believe this company took advantage of me. ( and probably hundreds of others out there). Controlling Systems did not provide parts cost, labor costs, etc in their estimate which they used to (I had used them 3 years ago, but I won't ever use them again) Future potential customers take heed: I WOULD ALWAYS REQUEST THE ESTIMATE REPAIR BILL BE BROKEN DOWN to parts cost, labor cost, etc. And if they tell you they can't provide that, that's a good sign you're being overcharged.
Normally I am careful about negotiating and reading the fine print, etc. but this day I was distracted and the temperature was in the teens. I wanted the furnace fixed and I didn't have time to get estimates. Also if I hadn't  used Controlling Systems I would have been charged the $100 diagnostic(service) charge. Lastly, Sean intially quoted me $700. When I told him I was going to get other estimates, he lowered the estimate to $597.

FAQs for swamp cooler service or repair projects in Longmont, CO

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.
