My husband and I decided to have a humidifier and u/v light air scrubber installed on our heating system. Senior technician, Dago, was scheduled to do the work, and we couldn't have been happier. His level of professionalism and attention to detail are qualities rarely seen today. We moved into a new house 9 years ago and our a/c and furnaces have never been serviced until I contacted Sierra Air for annual servicing.

When Dago arrived to do the installation of the new systems, there were issues with our furnace that were not done correctly when the unit was installed by the builder. Dago corrected these issues prior to installing the new humidifier and air scrubber. He was determined to have everything done properly. We were so impressed with Dago's level of expertise, his work ethic, and his high standards for doing the job right. He takes pride in his work, and it shows. Thank you, Sierra Air and Dago, for a job well-done!
