"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"

"From beginning to end, The Right Choice Heating and Air Conditioning Co. provided superior quality customer service and onsite work. From scheduling, to multiple follow-ups and reminders, re-confirming exact appointment time, and the post-inspection follow-up, they have truly impressed us. More importantly, Michael Taib, the technician who performed the work at our home, was indeed a true gentleman and professional. He was extremely knowledgeable and patient. I am familiar with the type of HVAC related work requirements, the lingo, and technician data. I quizzed him several times and he constantly responded with 100% honest and factual answers. He tirelessly worked on both of our HVAC units and performed the necessary services and repair. He was polite, courteous and clean. His most impressive talent was ensuring my wife's absolute confidence in his work after she grilled him with so many questions! We will continue to refer True Choice to all our friend and family! Call them; you will not be disappointed."

"We had our hot water heater replaced and I'm impressed! They didn't charge me extra for calling after 5pm. I was scared of being charged for an emergency call. They texted info of the technician coming to my house. As a woman, I appreciate knowing WHO is coming to my home. I don't want just anybody coming with my child in the house. This is a great family company. They arrived as promised and promptly stopped the old water heater from flooding my garage. My new water heater works great! They fixed my pressure regulator and I can enjoy my house again!"

We look forward to building long-term relationships with our clients and guarantee your satisfaction!

"Had them do 2 units on my property. The first one was great, the pre team is great, and the guys who actually do the work. After the 2nd one, where I chose the more expensive option to get a Mitsubishi Heat Pump, the unit would not turn the fan on some of the time. I told them, and wasted insane amounts of time. They kept saying things like 'I am trying to understand what doesn't work.' 'Pretty simple, you choose to run the fan to simply circulate the air and the icon goes, Nest thinks it is on, but does not go on.' Then they said they were going to have a Mitsubishi tech come out and for sure it would get resolved. Never happened. Just listened to a book on Benjamin Franklin and he and John Adams had to share a bed one time while traveling and Adams went to close the window and Franklin said this place will be a tomb if you do. That was what 250 years ago? and HVAC is their business? Guess I will have to take them to court. The office staff post job is a clown car of silly children. So if your job goes great, they will be a good choice. If you run into an issue you will wish you hired ANYONE else. You've been warned."

FAQs for swamp cooler service or repair projects in Walnut, 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.
