Get matched with top swamp cooler installers and replacers in South Pasadena, CA

"I had a great experience with your team. They serviced and repaired my mini-split and central They serviced my A/C systems, added refrigerant, and made sure everything was working properly before leaving. Mike was thorough, professional, knowledgeable, and did quality work. I highly recommend this company."

"Their technician, Justin came out and assessed the situation, quickly discovering the true source of the problem: the wire bundle that connects the system with the thermostat on the wall and been chewed through by rodents apparently, and this was causing the system to quit. He offered to replace the wiring and do a service on the roof mounted AC condenser unit, which we agreed to. Total cost was a fraction of what we had paid the previous company to not even discover or fix! We would wholeheartedly recommend the services of this excellent company."

"I own a laundry and needed two new swamp coolers. I called DNA and Andrew came out and from our first meeting was very professional. He was knowledgeable and able to answer all my questions which put me at ease. These guys did a bang up job. They were clean and made short work of removing my old units and installing of the new ones. I would highly recommend DNA for future work."

"I needed my HVAC system urgently repaired, the technician arrived promptly to resolved the issue. They were professional and knowledgeable and gave me honest recommendations & also was very helpful. Highly recommend! Thank you!"

"These guys were great. They did a great installation. It was completed quickly & at a better price than the other companies I checked. I highly recommend this company, & will use them for any of my HVAC needs in the future."

"Cal Climate Corp had been keeping my very old ac system alive for the past 3 years at a reasonable price and with excellent service. Bob and Tom are honest and conscientious so when the time came to replace the entire ac system, I was happy that they were available to do the work...particularly in the midst of another sweltering Southern California summer. The quoted price was much less than I anticipated, the work was completed in one day, and I was perfectly comfortable leaving them to do the work unattended. I returned home to find my home as clean as when I left it...and, thankfully, much cooler. I recommend them unreservedly."

"Initially I considered having to pay $8000-ish for a replacement unit. Robert Alfonso saved the day, however. Well trained by LA Tech, and professional from start to finish, Robert diagnosed and resolved my wiring and capacitor issue quickly. The fix was $485 not $8000 to replace the unit. These guys are legit. Great result. Robert "Doctor" Alfonso rocked it."

"Excellent customer service. Made two systems operate and gave important knowledge of the future life of these 15 or more year old systems and how they will need to be repaired or likely replacement once the new environmental laws on Freon goes into effect in 2020"

"We have used Darrow before for our unit and the condo association and were extremely satisfied. We called him again when our heating unit stopped working. We called on a Friday afternoon and we asked if he could come out the next day or Monday and he insisted that we not wait (since we were having a cold spell) and came out the next day and worked around our schedule. He's friendly, knowledgeable and his price is always fair and reasonable (and he didn't charge extra for a weekend). He also diagnosed the problem right away and didn't try to sell us things we didn't need. He also noticed on the roof a problem with our neighbor's unit and he replaced the cover to a water spout so they wouldn't get water leaking in (and did it at no charge). We're always apprehensive any time we have to hire someone for repairs, but Darrow has proved himself to be our go-to person for heating (and air conditioning should we need that). He has a great work ethic and cares about his customers."

"He came on a Sunday call. Very trustworthy and efficient. Concerned that I do not spend more if not needed. Tune up of the AC condenser. Working great now. No additional expense. Will definitely recommend to others."
