Atlas Trillo professional service highly recommended, esp. of Richard T. as advisor, Alex and Carlos as installation technicians, and also Lowe's agent for payment; many thanks again! A third-party inspection by a testing company named iPermit for HERS test (CA energy code) was also scheduled.

Vince came and made an estimate of cost and materials for my new water heater. He was very professional and installed my new Bradford white water heater in a timely way. He did apply a discount. This is the third time I have used this company and have been very satisfied. Grace

I appreciated not only being able to pick a target block of time for service, and was delighted to then get updated shortly after that by an email containing a specific 30-minute time slot when I could expect the technicians to arrive!
William and Jason then arrived within that time slot, were very professional, courteous, and thorough in asking questions about what was happening, in order to diagnose and completely fix the issue. They also provided multiple potential backup plans (though not needed), in case the initial solution did not fully solve the issue.
I'm thrilled with the service we got from Atlas Trillo and will call them again as needed in the future!

Atlas Trillo installed my HVAC system. My city's permit inspection required the installation of a seismic automatic gas shutoff valve. Atlas Trillo came back and installed the device to allow the city to issue the permit. The installing technician George did the same outstanding work with this valve as he did with the original HVAC installation. He deserves a raise.

Anthony from Atlas came to do a heating system check and tuneup in my home. He was polite, thorough, professional and reasonable. Didn’t push any services but pointed out potential problems in the next few years. Goof experience for me.

Technicians were on time, diagnosed and repaired the furnace problem and were very nice. Supplied a new simple on m-off thermostat to replace my old, over- complicated one! Excellent service. Kudos go especially to Marian in the office for help above and beyond, and to David Downs, technician whose persistence paid off.

Nick from Atlas Trillo came to my house yesterday and did a seasonal tune-up on my HVAC system. He was friendly, knowledgeable and did excellent work. He gave me excellent information on how to take the best care of my HVAC system to help it run at top performance for as long as possible. I highly recommend Atlas Trillo for HVAC systems, maintenance, and repair.

He did an amazing job figuring out what the issue was with my furnace. He showed so much knowledge, and caring that I understood the issue. Also showed me how to operate the thermostat. I’d want him on every call out.

Alfonso was extremely thorough and patient with all my questions and walked us through the process. We had a main line master toilet clog and our toilet was not seated properly and the misalignment caused a leak in our garage onto our cars. Alfonso pinpointed the issues leading to the leak and was able to carefully get his heavy equipment upstairs 2 flights of stairs and without damaging anything. He also gave us live cam recordings of the sewage line and we found pine needles in the lower spouts of the line which he said if the issue recurs the could dig up concrete find the offending clogged pipe and replace and repair. I would recommend Alfonso and ARS they were very responsive and nice and didn’t nickel and dime us for parts like roter rooter quoted.
